I built a lay-down desk

In an attempt to be more of the former than the latter, if the string or especially that strut sheer off of their mounts, that whole contraption is slamming down. Your groin is pretty well protected, but you can still catch that upper bit in the teeth. Figure out how far stuff should move and add stops to keep it from going a hair farther. Replace most of the nails with bolts (beware of end grain, which can split, in which case nail/bolt makes little difference).
Aside: My personal favorite trick that doesn't get used enough is eddy currents. If something has to move easily but not too quickly, a piece of aluminum, copper (or I think non-ferrous steel?) and a rare earth magnet will decrease the terminal velocity of the moving bit. You still take a hit, but you might walk away from it.
You do you, but this is my apartment. It is there especially to allow me to do the things that I want to do.
If this person is not doing carpentry work at 12 o’clock at night, they’re not disturbing anyone with their activities.
Your position is completely unrealistic. Everyone causes a disturbance at times, but we generally try to minimize it and limit it to reasonable hours.
I live in NYC and do projects like this chair all the time. I talk to my neighbors and ask them when they wont be home or when would be a good time to do X hours of work.
Most of the time they say don't worry about it as long as it's not past like 9pm or before 10am. I extend the same courtesy to my neighbors in turn. Just communicate and be reasonable.
See, this is where our opinion differs. I am perfectly ok with anyone doing it. I think this probably heavily depends on the culture you grew up in.
Or maybe some people are just intollerant, I really don’t know.
Seriously, everytime there is some kind of pro-urbanist post here on HN, I think to myself "sure, but noise". And people who don't value peace and quiet.
Now if you have any ideas for noise outside I'm open :-) A hipster bar opened opposite last year (when we moved in there was a commercial unit that had been empty for a few years, turns out it was a restaurant with alcohol license before), and we regularly have drunk people speaking loudly/shouting outside in the evenings from Thursday - Saturday. We can obviously close the window (triple glazed), but it's nice to have a breeze coming in.
I live in an earthquake zone. Masonry construction is illegal on almost the entire US West Coast.
Cities are just large human settlements with high density and a (mostly synthetic/mental) boundary defining it's area.
One of the many parts mostly any city has are residential areas. Noise is absolutely not desired there, even if you think it is. What you seem to be talking about are public, business and industrial areas for example. Demographic development has people living there, sure. But mostly because it's cheap because of the noise and other environmental issues.
Thankfully despite your opinion New York does a good job of putting these noise complainers in their place. Unless the noise is beyond the pale or at hours between 10pm and 7am, complainers are told to GTFO most of the time. Somehow the city still remains a highly sought after place to live, half of it because all the whiners who need silence for realigning their chakras have decamped to Hastings-on-Hudson.
It doesn't have to be loud!
I literally vacuumed under my sleeping girlfriend (and it's not like she sleeps that deeply on the sofa, it just wasn't louder than the running TV). The loudest part is, unless you turn it to max power, the scraping of the thing over the floor. Compare that to the upstairs neighbours, who we barely hear except when they vacuum.
My mom's first reaction, when I excitedly told her, was "yeah but those don't have any power". Not sure, I've used a bunch of vacuum cleaners over the years (old or second-hand in student rooms, newer stuff at my parents' house) and this one doesn't do any better or worse than others. The EU also reduced the max power of new vacuum cleaners, apparently they're overspec'd for the job and people just buy what they think will get them done faster I guess? Haven't read up on it, I just remember reading that the max power allowance went down as of some recent year. Perhaps the loudness is subconsciously a proxy for performance since an ordinary person can hardly measure suction directly?
In the EU, appliances have a score card. In the case of vacuum cleaners it contains things like how well it vacuums, how much dust comes back out while vacuuming, how loud it is, how much power it uses, and another stat or two that I don't remember. They're all roughly the same (I just walked through the store from vacuum to vacuum for each stat to see what the best is you can get per price category) in pretty much every stat except noise level and power usage. In those two categories you can win a bunch for virtually no extra money and I'm super happy with it.

These contraptions cost more than my car... But they do seem to be safer. Nothing hanging above the user's head.
I was trying to find a used/rent/borrow arrangement for a device called a log arch a few years ago, to help with a landscaping project. This is how I discovered just how many people have learned to basic to intermediate welding to avoid the labor costs of having someone else do low-volume work for them. Especially out in the boonies.
This thing is a nice first prototype, but it looks like a death trap. There is absolutely no reason for the giant lever arm coming up from behind you and all the way around.
Look at the altwork design. It's a lot lighter and more robust. It doesn't place a ton of weight overhead, and there's a lot less leverage on the joints. Or look at ErgoQuest. The monitors are stationary, and only a lightweight desk/keyboard tray moves.
I appreciate your confidence, but I'm afraid it's misplaced. I've been doing woodworking and engineering for a lot more than 15 years. A couple of things to consider:
"When you want to build this kind of structure, I'm not sure you can plan everything beforehand, there are always things that will happen that you didn't expect." You absolutely can. It just takes practice and experience. When I build something, I plan out what I do, and 9/10 it comes together on the first go. For my mentors, it's 10/10. The first few years I was doing this, it was 0/10.
"After a few failing choices, I ended up with a main pole of 7cm x 7cm." You generally want about a 10x safety margin for dynamic loading and similar issues. If you had a few failing designs, you're way too close to failing in your current design.
Back to the overengineering point: Simply using massive beams of wood and bolts doesn't necessarily make things robust. A 7cm x 7cm piece of wood weighs a ton, and puts that much more strain on everything. That's true for all the pieces. I could build a more robust design with normal-sized boards. That has the distinct advantage that if there is a failure, what falls on me my hurt me, but won't kill or cripple me.
I'm glad you're trying, but by overestimating your expertise, you're putting yourself at risk. I'd encourage you to keep trying, but to also take this sort of constructive criticism seriously.
Think through how the desk ought to move so you don't need the giant lever arm, whether you want the monitors to move at all, and where to mount these so you can get in and out easily. I can think of a half-dozen designs where there are no massive lever arms, where nothing moves or just the keyboard tray moves, where if things break, I don't die, and generally simpler, lighter, and more robust.
I'm going to quibble with the other response about the arm above being over-engineering. You're copying existing designs instead of trying to work out your own geometries. You could probably move the moving parts behind the monitor, but I don't know how hard a time you'd have keeping the footprint from increasing.
The people who actually build cool stuff left because they didn't like a bunch of people with little to no experience in the things they are doing telling them about how they should have done them and that should have worn more safety glasses, used more jack stands and that a Dremel is going to eat their hand if they use it while wearing work gloves. Nobody who's actually contributing content of any value is going to stick around somewhere they have to take shit from a bunch of internet riff-raff that isn't contributing anything.
There's calling out stuff that's actually unlikely to last and there's pandering to the safety crowd for virtue points and the publicly accessible internet is rife with the former while actual constructive criticism is proportionally rare. For every comment to the tune of "you should consider fastener X because your application is Y and that plays to X's strength Z" there are ten teenagers (or adults acting like teenagers) making some low effort jab about something in the building code, or some written list of best practices, they don't understand the reasons behind.
It takes time and effort to build something. It doesn't take any time and effort to make some quip about PPE so that a bunch of teenagers can click on an up arrow and you can get your fix. The people actually building things got sick of being used like that.
Ah, yes. The exact realization I had, 26 years ago, which made me finally give up on asking questions in EFNet #Linux.
try /r/woodworking for a more mature conversation.
The people who know they fucked up post self-deprecating pictures for a group chuckle. Showing your first dovetail (even if it looks like a 10 year old made it) is practically a rite of passage. The rest of the projects are usually small enough they can't kill people, or anchored to the floor so you might lose a toe at worst.
I still laugh. Perhaps true in part though.
You can bounce aroundd on it which is fun too as the seat is mounted on a spring like a pogo stick.
Apparently this bouncing helps keep the joints lubricated.
Some days I actually sit on it for 8-10 hours (I hate to admit it).
I do take breaks and it can become fatiguing so occasionally, I feel like having a slouch so I go lie on the floor or use a regular chair (with decent posture) for a break.
Probably what this chair has done for me the most is make sitting with bad posture feel noticeably strange and unnatural.
There must also be something to be said for the fact that there is a “ramp up” time. I don’t think I have a stronger back from using this chair alone, although I guess I do have a less damaged and atrophied one. I do remember a time when it felt like certain muscles were getting stronger. I vaguely remember it taking a few months to become comfortable.
It’s worth mentioning that I do a fair bit of weight training too and that I’ve had the chair for about 8 years.
(Just for the benefit of anyone interested and trying to search for it :))
Edit: You probably also should focus on core work too. Try some forearm planks to start.
your shoulders will shrug and round forwards, which will limit your range of motion over time. any stretch that retracts the scapula should help; also if you do any exercise like a row, make sure to focus on really pinching your scapula together.
your core muscles will weaken, leaving your spine more vulnerable to injury. "hunched forward" will become your default posture which exacerbates this further. your spine is actually really strong when it is aligned properly, but you need good core strength to do this. doing a "hollow body" pose and your basic plank are good ways to strengthen these muscles (overarching your spine in either direction is a problem).
I'd say anything that engages the core (superman, plank variations) and activates the upper back (YTWL's) would be good choices, ideally substituted with some stretches or mobility work
Forearm plank, side bridge, bird-dog, dead bug.
This video is a meta-analysis of the best rehab exercises for the glute muscles: https://www.youtube.com/watch?v=EgWSsaC3UJk
This page has pictures of the above mentioned PT exercises: https://mikereinold.com/5-common-core-exercise-mistakes-and-...
I recently did PT for lower back stuff mostly related to sitting for long periods.
I went from constant “3-4” level pain to “0-1” pain. I’m still working on strengthening, and re-injured my back moving something heavy, but PT was a game changer.
A lot of stretching like the above video shows, as well as working on posture, sleeping position, as well as just overall education on how my muscles work and what to do when I feel them tighten up or feel an area swelling up.
It’s mostly simple stuff but requires habit changes and can be time consuming so you have to fit it into regular routines. Stretching before/after bed, while you brush teeth, etc.
You look weird randomly stretching on a stair while you stir your tea, but it can make a big difference.
Among the many other things I had hammered into me about health when I was a kid in the late 1980s and 1990s that I've come to reject is the incessant hammerbeat about aerobics, aerobics, aerobics. I think the evidence is that the average person is better off with a lot more strength training, which will incidentally train you on some aerobics, and if you feel like occasionally folding some aerobics in, hey, go for it. They're not bad or anything. But they ought to be considered a specialist training, like working out legs specifically for biking, not a default that everybody do. Strength training is a default everybody should work on. Strength training isn't so you can lift 300 pounds when you help your friend move... it because it makes everything work better. You sleep better. Your back hurts less. You fall less. You build a better base for aging.
Similarly, I used to get eye strain from all the screen time. Until I moved to an office with a view and I found myself staring out whenever I would zone out to think. Now I'm working from home and don't have the same inducement to look out and my eyes have started bothering me again. I try to observe 20-20-20 (every 20 minutes spend 20 seconds looking at something 20 feet away) but it's not quite the same.
These days I just make time for moving outside of work and change my position at work. Standing desk, sitting on an exercise ball, sitting in a chair, repeat.
From his blog post:
> But while standing may be better than sitting, I like to at least start my day with something more active, and for more than a decade I’ve been making sure to walk for a couple of hours every morning. But how can I be productive while I’m walking? Well, nearly 15 years ago (i.e. long before it was popular!) I set up a treadmill with a computer in the room next to my office:
> The biomechanics weren’t too hard to work out. I found out that by putting a gel strip at the correct pivot point under my wrists (and putting the mouse on a platform) I can comfortably type while I’m walking. I typically use a 5% incline and go at 2 mph—and I’m at least fit enough that I don’t think anyone can tell I’m walking while I’m talking in a meeting. (And, yes, I try to get potentially frustrating meetings scheduled during my walking time, so if I do in fact get frustrated I can just “walk it off” by making the treadmill go a little faster.)
Only downside is that when having video meeting, my head is bouncing while walking. Usually leads the conversation on treadmill.
If you are suffering from back pain caused by sitting and have trouble sleeping, I used this video [1] to relieve the pain for a while. It helped so much that after 2-3 weeks of doing it every day 2-3 times, I was able to sleep normally again. I also slept on the ground for a while since my mattress was too soft. I now own a very firm mattress.
Supposedly it's good for patients that stay in bed for long periods without moving as it improves circulation, reduces back pain and prevents bed sores.

I could hardly believe it myself, but it is true.
The "local police may harass you anyway" part threw me off as I thought that's a reference to something actually happened.
Seems cool, but I prefer to drive myself. Maybe I'm not cut out to be an executive? IDK
If I had the space I'd consider it myself. Like you, I can drive five hours without stopping and be fine the whole way and when I get there.
It'd be nice if being comfortable at a computer all day was as easy as changing the seat but i don't believe that's true.
As someone who lives in the midwest, I have to disagree. Pick pretty much any random 100 mile stretch of I-70 or I-80 between the Appalachians and the Rockies and the majority of it will be straight enough that you could set the cruise and only have to turn the wheel a few degrees at most as long as traffic doesn't do anything stupid.
When I was younger and dumber I once drove from I-71 near Cleveland almost to Chicago with just my knee on the wheel. There's a kink about half way across Indiana that was the only real challenge.
Having recently (and historically many times before that) drove both I-70 and I-80 in the area indicated, I feel you’re being a bit hyperbolic. I’d agree both are as described for some 100 mile stretches (I-70 between Hays / Salina KS and I-80 between Lincoln / Grand Island NE as two examples), but not any random section.
>so basically just a desk that constantly moves around?
No, a desk that has a gyro grill attached.
Seriously though, one thing I did find was when I quit smoking my ability to solve complex problems at work went down for a while. I was no longer taking a forced 10 minute break every 60-90 minutes that let my brain reset. (Or explaining my problem out loud to another filthy smoker skulking around the back of the building :D )
Fortunately for me it was about the same time that the Pomodoro technique was featured on Lifehacker and I implemented a similar system to replace the regular nicotine craving induced breaks.
It might also be the lack of breaks too, but who knows.
I have an electric standing desk from ikea, and bought a walking pad (movable and foldable) for underneath.
I was scared that walking would make it too hard to read code, but it actually works really well. I would recommend it to everybody.
Mostly I walk about 30 min to an hour in the afternoon. The rest I sit.
https://medium.com/@truppr/long-sitting-how-it-affects-your-...
I'm a big guy, 6'4", and fidgety. Being tall, I learned early on good posture is crucial for a pain free back, as is strong back muscles. Between that and being always moving, I don't deal with a fraction of the body issues a lot of office workers seem to. The worst is long flights, because getting up and walking around at least once an hour is something I don't even have to think about, so planes aren't great for that. On planes I understand why people want comfort at their desk.
The sitting posture matters because the spine is kept erect naturally, like a vertical pendulum. Once you get used to it, it is a pretty relaxed posture that feels quite sustainable .. compared to sitting in any chair.
I've also taken to being fairly strict with a Pomodoro routine. 25 minutes focused (strictly locking down email!) work, 5 minutes when I get up and have a wander around the house. I think my attention is better, my eyes get a chance to rest, less aches.
The other thing I did was to start using mouse left-handed. I got terrible RSI with my right (I'm naturally right-handed) and actually although I'm slower with my left it's no bad thing - my movement is more considered, less jerky, and I think has a lower impact on anything likely to trigger RSI.
So yeh, I think I'm ok for a death-trap lying down desk, thanks anyway...
There's a reason the guy in the image is like 90+ years old and either suffers from immobility and/or nerve issues. Anyone more healthy than that would feel the need to squirm and get up long before one would form.
Also, the way we sit in a chair isn't exactly activating any muscles over just laying down or reclining in a La-z-boy. For that reason I do like the idea of sitting on one of those inflatable yoga balls when I'm not standing.
I bet you could burn an extra 200 calories a day just incidentally bouncing as you ponder HN.
It’s folks who are bedridden and don’t have the ability to move themselves around that get pressure ulcers. Combine that with poor circulation and potential nerve damage (diabetes) and it’s not hard to do.
A health 35 year old? You’d have to force yourself to get a pressure ulcer.
I've now come to the conclusion that low latency video glasses/headset connected as external display to the laptop/smartphone is a better solution for that problem as it doesn't require any of these contraptions; But I'm still in search of one[1].

Disclaimer: I'm an investor in Immersed, but I invested because I loved the product!
But, those who have no issues with VR might indeed find immersedvr useful.
Thanks, now I'm intrigued. I'll have to checkout Quest soon.

The real problem is no VR headset has a resolution high enough to come even close to what a normal monitor would provide dpi wise.
I guess you have to find a low weight VR set though.
I completely get it because of how easy it is to get lost in the VR experience and forget about the outside worlds. Seems great for productivity. Might have to try it out sometime.

For people suffering from severe RSI -- especially those for whom essentially any amount of sitting in one class (say "sitting"), even in difference positions within that class -- becomes unbearable for more than an hour or so -- then this 33 percent can be of significant impact.
Also - for some people standing just doesn't work (for more than very short intervals). So in fact the lying option provides significantly more respite potential (50 percent).
Google "pressure ulcer" / "bedsore".
Then for ultimate convenience (laziness) I connected a bluetooth presentation clicker to my iPad to turn the pages for me so I didn't have to keep reaching up or take my arms out from under the blanket on cold nights. In two years it's never dropped.
Is there a way to use the clicker with the kindle?
I keep thinking of assembling about the same thing, but missed the warm-blanket factor. Now I definitely must do it.
This must be today's "most HN" comment.
- Dismisses a new project that simplifies a task and makes it more approachable to non-technical folks (Like the famous Dropbox comment [0])
- Is extremely pedantic and serves only as a distraction from a discussion
- Argues in favor of pure functional programming
- Misses obvious sarcasm, even when the /s is included.
- tries to come up with an overly precise technical definition of something entirely subjective and unserious.
;-)
There's always someone that's religious about their particular technical choices.
* dismisses the thought by referring to the commenter's privilege for having it in the first place, rather than commenting on the value or feasibility of the thought itself.
Can you think of any other community where someone can discuss the damage of a CRT monitor falling into your face with terms like "scale linearly" and everybody just nods in agreement?
I think it's delightful, one of the little pleasures of hanging around here.
And some of the later generation CRTs breached 20" and were a good 30+kg.
Sony's 24" GDM-FW900 was a pretty incredible 42kg.
I use them for reading in bed, although sites do everything in their power to make landscape mode on mobile phones unusable.
I have a standing desk that earns me a closed cyan ring every day.
Cool project, but would not be one that I would use.
Is this referring to some tracking software?

In my experience, I've found a MS Surface and a gooseneck ipad holder is a lightweight ideal laydown desk. I clamp the gooseneck a few feet above me in bed and I can lay perfectly flat and have access to a full PC.
It also can be disassembled and stored in moments.
Could you please point me to your choice of stickers, or mention the brand? I desperately need some bumps on the current keyboard and thought of messing with glue and plastic, but it hasn't occurred to me that someone already made a finished solution for that. From searching, I now see a bunch of related stuff, like braille and such, so it would help to narrow it down to more suitable products.
Laying down and typing is at a weird angle so you can't quickly check that your fingers are aligned right. It is just easier to have a tactile anchor at the far end of the keyboard, particularly when typing fast.
It doesn't take much, just the smallest sticker can change the feel of a key.
It was incredibly comfortable, and uncomfortably decadent at the same time.
Now we have adjustable beds and a TV in the bedroom, so that's easier.
Mount the arm to something (like a desk) and swing it over the couch to lay down. In my case, I can actually pivot it between the couch and the chair on the other side of the desk.
Great for a few hours a day when you want to sink into focus mode. Super highly recommended it.

I actually think the biggest downside to the multi-station dynamic setup is that the ideal monitor configuration for that is a single curved ultrawide, and there are essentially no high resolution options.
I think raising my hands up higher (90 degrees as you say) would actually be a lot worse. Never understood that aspect of all the more "real" laying desks.
I should note that I purposely don't use a mouse with this setup, because it would end up being quite far away and would need to be on a solid surface.
If you happen to like the ThinkPad TrackPoint mouse nub, these keyboards work great for that type of setup: https://www.lenovo.com/us/en/accessories-and-monitors/keyboa...
And this monitor: https://www.rtings.com/monitor/reviews/lg/32ud99-w (specifically because it's the only USB-C monitor I found that's completely flicker-free, which RTINGS tests for).
Ergomart actually looked at the specs of my monitor and recommended the right arm and parts to properly balance the weight. I'll happily recommend them recommend them.
The monitor moves easily on three axes, and tilts; cords are cable-managed through the pole. I just sit down and plug in a single USB-C cable to get video, webcam, keyboard/mouse, and power.
That's a lot of weight and hinges in this system. It looks like a guillotine for the stomach.
As I stated at the top level, I'm not a fan of the hinge, but the side braces he added to hinge were a good idea.
And contrary to what we can imagine, there is not much weight, the right part of the desk, which could fall on me if something breaks is about 40kg. Thats the advantage of wood, it is very light
1. There is a failure near the top of the stand. The whole thing comes collapsing down verticaly
2. There is a failure in the swing-> pressure is pushed towards the user. I just saw that the table connects to the chair.. looks like that would mitigate some of the force
3. When pushing the desk out to get in, there could be a failure at the pivot point above..if you're sitting in there.. that's a post going to the head.
Posts are VERY heavy. They're even worse that high up and above you.
The workstation is awesome technology; it's really well built, nicely runs wires everywhere, etc. My only complaint is that the headrest is too hard to be lying down on it for hours at a time -- I fixed that by putting an old sweater between my head and the headrest, which made it perfectly comfortable for me. One thing that might not be obvious is that it takes up surprisingly little space -- something like 4' x 6'.
Talking to them about the delivery, a lot of their customers are other folks with medical reasons to want it, because I think that's what justifies the price point for people. But the price will come down with scale (there's already a $4K model: https://altwork.com/products/flex-altwork-station?variant=34...). And at that price point, the price is immaterial compared to software salaries, at least if you think about it as a capital item that will amortize over many years.
I would not know where to lay down all my paper notes though :)

Then gradually, I sink into lying down and my laptop held on it's bottom edge on my chest, knees keeping the laptop upright.
Finally, I know it's time to go to sleep when I doze off and the laptop hits me in the face.
I always dreamt of having a laptop stand that could suspend the laptop above me while lying down. I guess this guy made it happen.
It basically looked like a desk lamp with a tension holder at the end.
This is no different. Sit too long; stand too long; lay down too long. All bad for you in the long term.
I switched from a sitting to a standing desk with a high chair. This allows me to switch between sitting and standing multiple times per day without having to fiddle with the motorized desk too much. I make it a point to go for a short walk a few times a day when I transition from sitting to standing. And exercise is key.
I've seen lots of these desks that allow you to lie down. From my perspective, this is a horrible idea unless there's a solid medical reason for it. In other words, someone with a condition that almost requires it. People in bed at extended care facilities develop all kinds of problems. This is no different. Almost every muscle in your body weakens. Not a good thing. I hate to think what happens to gamers who buy these desks and sit there for ten hours at a time playing. Horrible stuff.
Avoid the extremes at all costs.
Some people who've tried the new HP Reverb G2 are claiming we've already reached that point.
I'm not so sure myself but it's pretty close.
At the rate display resolution is improving, I'm quite sure it will happen this decade.
Also, this article about how different distances between eyes, pupils etc could affect VR was fascinating: http://tomforsyth1000.github.io/blog.wiki.html#%5B%5BVR%20op...
Can someone provide a link to elaborate? My intuition would be that you wouldn't need any more pixels, just smaller pixels. It feels like the aforementioned claim is comparing apples to oranges: to fill your entire FOV with desktop monitors at normal distances would also take about eight monitors.
To put this in Snellen eye chart perspective, in order to read the 20/20 line and distinguish letter details to tell them apart, you have to be able to see details as fine as 1 arc min - 1/60th of a degree.
So basically if your math comes up with less than 60 pixels per degree, you are going to essentially be near sighted inside of the VR environment.
Let's say you have a set of VR goggles with a 140 degree field of view. You need 140 degrees * 60 pixels/degree =8400 pixels to get that same visual acuity as 20/20 vision in real life.
Using HP's new G2 goggles (coming out soon) as an example, they have a screen resolution of 2,160 pixels,and (I've read) about a 100 degree horizontal FOV. That works out to about 22 pixels per degree. Which is about like having 20/55 vision. This is why in VR, you can't read things from a normal distance if drawn to scale. You have to either get closer to them (in VR) or scale them up to make them readable.
You CAN give the user effectively better vision by reducing the field of view. If you don't mind having a 36 degree wide field of view, you'll have 20/20 vision.

Picture of my setup: https://imgur.com/a/OLhkrPV
Bought a used Aeron chair about 10 years ago and is still working fine. Love the Kinesis Keyboard, also about 8 years old.
The Lounge chair needs to be replaced once a year ($50) because by that time the fabric on the back becomes saggy and will start to cause discomfort on the back.
I don't like to use multiple monitors. Somehow I couldn't get used to it.
When I'm on the Lounge chair, keyboard is on my lap and I use the arm rest to make sure my wrist is not pressed against anything.
When I'm sitting, the armrest is adjusted to keep my wrist from touching anything.
I'm not kidding, if he'd dome some slight of hand with chicken parts, I'd totally believe in that psychic surgery crap.
But before that, I created a mount for a laptop and second monitor that would clamp into my bicycle maintenance stand (Ultimate Support Classic), and I could rotate the arm around to bring the screens to a comfortable location.
The biggest problem I had was that there was very little arm support. I could rest part of my forearm on the chair's arm rests, similar but less so than what the article has. Maybe in his case that's fine, but for me it was like holding my arms out in front of me at a 45 degree angle and after maybe an hour it was pretty painful in my shoulders. I probably would have added some additional armrests to it if my back problems hadn't been solved and I decided to abandon it.
I was happily using a Thinkpad keyboard with trackpoint at the time, so the mouse issues didn't impact me. One could also imagine a counter-weighted mouse, with the weights hanging off the back, via a pulley sort of system.
I also found being entirely static for hours at a time wasn't that comfortable, and that sort of "bucket seat" really doesn't lend itself to anything but one position.
Maybe a decade after that, I tried another experiment that worked pretty well. This one I guess I'll call a "lounging desk". I got a nice leather club chair with ottoman, and a big, heavy entertainment center that I put to the side of it.
On the top of the entertainment center I had my laptop and one 30" monitor, and then a monitor arm holding another 30" monitor. This was in front of a window so I could look outside. I could swing the monitor in front of me, and the club chair allowed me to sit or recline or curl up, lots of different positions. This was actually a pretty nice setup, and if I hadn't shortly after that moved jobs to an at-the-office setup, I'd probably still be using it.
These days I find switching between sitting and standing to be very comfortable.
With the exception of the two monitors, which were $1,100 each, the setup boiled down to roughly: $300 for super duper monitor arm, $250 for the entertainment center (close out from fancy furniture place), club chair I already had, but was $350 from a going out of business furniture place. Also $50 for a couple USB hubs I sticky tape mounted conveniently located on entertainment center (computer was back behind entertainment center).

Situation: When I was ~17 one night I slept kind of oddly twisted. I was kind of stretching my back and fell asleep and woke up with a sore neck. It stuck with me for years at some low level, massage would help a bit but it would never really go away. The pain was largely in the area where my neck and shoulders met, say around the size of a salad plate.
I woke up one morning when I was around 30 and it was so painful I couldn't sit up from a laying position to get out of bed. That's when I saw the Osteopath. A physician friend recommended I see them.
They gave me these "super ibuprofen" and isometric exercises, and literally it cured me basically immediately.
Solution: The exercise involves standing up straight, and using your hands to put opposing force against the different muscles in your neck. Your head needs to remain unmoved, neck straight, it was recommended that it be done in front of a mirror so you could make sure you weren't bending and remained straight.
Isometric exercises are exercises you do where your joints and muscles basically stay static. If you put your hands in front of you, like the praying position, and press equally with both hands, that is an isometric exercise. Lifting something is not.
In all cases you gently start pushing and gradually push harder, and similarly at the other end start pushing less hard until you are not pushing at all to end it.
The exercises were:
- Clasp your hands behind your head and oppose tilting your head back. - Ditto on the front, trying to look down. - Hand on one side if your head by your ear and try to tilt your head to that side. Ditto for the other side. - Palm on your forehead and try to turn your head that direction. Ditto for the other direction.
Again: See a medical professional before you do such a thing, but in my case it solved a chronic upper back pain as if it were a miracle. Literally a decade of pain was gone after spending 5 minutes doing this. YMMV. On the other hand, my non-genetically related mother had terrible bone deterioration and several surgeries including cervical fusion and added metal bits to her back, and if she had tried these exercises she'd probably end up in the ER.
If this guy had spoken in tongues and pulled out chicken parts hidden in washcloths, while doing similar exercises on me, I would absolutely, 100% believe in psychic surgery. It was miraculous.
At first it looks really flimsy and jumbled together. But on closer inspection it seems more stable, and ultimately the proof of the pudding is in the tasting.
To one's own decapitation in the search for freedom and comfort!

I can't wait until I'm working in my sleep. /s
My WIP involves a Zero G chair from relax-the-back, a sit-stand desk from which I mount the three monitors only, and a side table for the Mac. I dropped the $$$ on the chair because (a) it is motorized so I can change position throughout the day slightly, and (b) because if I ever have to go back to the office 100%, the chair is nice enough to put in the living room. The sit-stand desk allows moving the monitors up and down. Finally I have a couple of pieces of foam, with an MDF board glued on top for a workspace. The foam rests on the chairs arm rests, and now also two more side-tables just to support the foam. I use two magic keyboards, one for each hand (karabiner is required to make the cmd key etc work across keyboards)
It is a WIP. Step 1 was taking the load off my neck. I can now totally relax it during the day, with the result that I am now taller. Step 2 is taking the load of my shoulders. My second iteration has resulted in my elbows being slightly above my shoulders, so I'll be needing to get some thinner foam.
I'm in for about $5k so far, mostly the chair.
Will hopefully get to a writeup when it is 100% comfortable.

I have one of the original prototypes in my flat and I've been sitting in it, while coding, 8-10hs every day. Pretty much since the lockdown started here in Germany and throughout the rest of this year so far.
The reclining angle is fixed in three steps from 125-130-135deg which is ideal, pressure wise[2]. The legs are up so far that they won't fall asleep (your feet have to be under your heart, vertically, for that to 'just work').
It is one the most comfortable 'chairs' I know. Before the lockdown I never used it for working, only for reading or watching movies. When there's a sit-in at my place there's usually a fight for it among the guests.
It doesn't yet have any of the contraptions attached to it to make it into a 'lay-down desk' though.
I usually work with a laptop on my legs and for that it's absolutely fine -- as-is.
Sascha is now looking into designing an extension that allows mounting 1-3 screens and a keyboard/mouse/touchpad/Wacom combo. Just like the contraption in the linked article. :]
With the caveats: it will be structurally sound (he's an ex aerospace engineer) and -- assumedly -- beautiful too.
I'll try posting this on the front page once his shop goes live.

The one thing I've always wanted to try though was face DOWN recline, like a massage parlor, approaching a sensory deprivation kind of experience. Again might need a lot of coffee beforehand though.
Would love to hear any reports from the daring adventurers who may have tried it. I think the blood flow to your arms might get weird, issue #1 ...
I did look into the AltWork setup mentioned. At $7000 (or $4500 for manual option), it's quite expensive but not that bad if amortized over a 20 year period of working 8 hours a day. Investment in long-term health is worth it if the product works as it should and lasts the expected amount of time.
Aside from my wife not wanting it in our apartment (I understand), there isn't enough evidence that zero gravity workstations improve health versus just a good ergonomic chair (ie. an adjustable chair that fits your body) and desk (adjustable and gets low enough to support 90° elbow angle without hitting your legs). In all cases, one needs to take breaks to stretch and move around, not to mention daily exercise.
Went with a HM Embody (armless) chair and IKEA Skarsta hand crank desk instead; zero regrets and I wish I got them earlier (especially the Embody)!
https://altwork.com/products/signature-series?variant=316179...
I bought an AltWork earlier this year when COVID hit and it's been pretty fantastic. Currently standing at it. 5 stars would reccomend!
That said, for lying down, you really want a trackball mouse (the alternative is to dock the mouse when not in use, which is OK if you mostly use the keyboard for everything).
The biggest problem was that if I used it for any length of time, my stomach core was in agony!
You get the largest screen you can afford (use it at a low resolution) Put it on the wall just under the ceiling.
Put a stack of books under the legs of the bed. This is an art in it self. If you gradually increase the angle eventually you slide down. Train the legs to "stand" like this and gradually increase the angle by tiny amounts. This way it magically qualifies as a zero effort leg exercise. (my legs got huge muscles from it)
Get thick curtains to make the room pitch dark. Switch off the lights, adjust the themes and dim the screen to the point you cant see anything on it anymore without getting used to the dark for 5-15 min. This will allow comfortable naps while coding.
As soon as a task feels complicated take a nap. It is hilarious to wake up and see absolutely nothing besides text on the screen.
On day 2, I discovered that I could spend hours lying flat on the couch with my legs propped up with cushions and a laptop on my 45deg legs. In that position, I could use the computer two handed for extended times as if I didn't have a broken collarbone.
Coming into the office to work (as COVID has been eradicated in my part of Australia) was harder since more than 20mins in an upright position (chair or standing) caused my shoulder to ache.
It took me a couple of weeks to work this out, but I ended up using a large upright shaped bean-bag as my office chair. I could mold the beanbag to give my arm support and sit the more reclined position that re-leaved aches. Having an Ikea standing desk helped, as I get into the bean bag and then lower the desk to match.
It's healed enough now to use regular chair and standing desk, but I learnt a lot about me and desk positions.
My main conclusion (after 15years of having a coding job) is that variation is key. There is no magic seating or standing position. Even if there was, it would be become uncomfortable eventually.
While probably the worst seating position for my back and posture, I have kept the beanbag chair at work, because using it occasionally feels good.
And, when at home I have continued to use the lying flat on the couch position, because again, it's different to how I usually use computers.
Which brings me to my main thought on this project (which I love the idea of): It's too permanent. I'm sure it'll feel amazing and comfy for a few days (or even weeks), but at some point for my body, it'd become just as annoying and uncomfortable as a regular desk.
I know you can build in mounts for that stuff, but I think there's a lot of value in how dynamic desk surface is. Need 2 notepads so you can see things side by side? Cool, put it on the desk. Working on 2 laptops today, because you got a new one? Cool, put it on the desk.
I wonder if you could find a way to to make things stay put. Anything sticky would get all over your arms. Velcro seems usable if you put the soft side on the desk, but it's ugly. You could maybe use magnets that you embed into your stuff to increase the friction enough that they don't slide. Won't help with tea, but it should work for most other things. Modern monitors and computers without magnetic hard drive are okay with magnets, right? (I can't say for sure)
Well, you are lucky that floppies are a thing of the past ;-).
Has anyone found a good solution for positioning a mouse and keyboard in front of yourself while sitting on a recumbent exercise bike?
My primary use case is exercising while gaming. I can somewhat get by when playing mostly-mouse turned-based strategies; I put a table next to my bike and use the mouse on that. But it's not good to keep my shoulder at that angle for so long, and I'd like to also play games that require active use of the mouse + keyboard.
So far I haven't found a good match on the market. I could build one myself, but TBH I'd rather not spend the time right now to iterate on the design.
Both setups are relatively inexpensive (especially for the "wow" factor) and can be done in a reasonable size room.

I recently have bought a stationary-bike-desk, hoping it will offset the sedentary nature of my job with some sweating.
It makes my home-office look ridiculous, but my legs are getting a workout.
Weird.
Or aim a projector at the ceiling
I also built a reclined exercise chair desk. https://twitter.com/richardheartwin/status/92085596458001612... Make sure to isolate the monitor stand from the bike stand, or it will wiggle unbearably.
Apple Magic Trackpad 2 with velcro on bottom. Even a vertical mouse could work too. Else something which ensures mouse doesn't drop (foam, cord not too long, a holster to store it, or something magnetic perhaps).
What is the effect of such a desk going to be on blood flow? Does this increase chance of hemorrhoids?
I'd just use a hangmat with a MBP for a simple lay down desk. More modular and less work. Or a bed + laptop; what I currently use for remote work. More out of necessity (noise and space constraints) though.
In my daydream, I am lying flat "on" ("against"?) a board, as if lying on a bed, but the board is at an incline of about 45 degrees. The board is of a slippery material like formica to make it easy for me to get on and off it, which makes it important for there to be a "ledge" at right angles to the board for my feet to "stand on"("rest against"?) so I don't just slide down the incline.
Components similar to the ones used in my setup:

The mouse is located on the armrest (I don't need to use it too often), and the keyboard (a heavy and thus stable one) is on my lap (I don't need to look at it while typing).
The leaning chair is basically a waist-high wall that you lean against. It does help me to better tolerate standing all day. Only downside is that it can hurt my knees if i don't use it correctly.
That said, working from home i sit less in front of the computer. That's because i can read something walking around or whatever, and there 's no reason to "look busy". I also find that a simpler immobile chair with no armrests keeps me more refreshed.

I can imagine being in this position as my cockpit for serious lengths of time.
You'll quickly figure out what you like & don't like, and because you didn't invest too much you're more free to hack it up later :)
I couldn't use this for any long time period, but each to his own.
Cool idea though, looks functional
My intuition is that as people's standard of living improve, bedding is one of those things that gets easily overlooked when you can't afford it but is somewhere investing some "real" money returns a good result.
I went from using the bed from my parents' house (which was a hand-me-down) to a dorm bed (briefly) to the absolute cheapest thing I could get my hands on that wasn't stained brown or covered in bugs. It wasn't until I was relatively successful and making ~$80k / year that I felt like it was reasonable to invest in a nice mattress, and even then, I came to the conclusion that the "mattress store" beds were way overpriced and had little to differentiate them.
I ended up with a memory foam bed off Amazon. It was ~$200 for a queen and I've had it for about five years. The biggest issue I have with it is that the fabric seems to take stains more readily than my previous mattresses. Comfort-wise, I'd put it on part with a $1,500+ "mattress store" brand, so I'm happy replacing it every few years and passing my old one on to someone who doesn't have a decent one. In fact, it's getting to be about that time...
If you need a desktop monitor, you can get an over-bed table and mount a small VESA mounting arm.
If you can spend 1k, the absolute best is to get a medical VESA arm and mount it to the wall. These can also have trays for keyboard and mouse.

I built a PC and don't even use it because sitting at a desk is so crappy.
I imagine this desk setup slows you down a bit, at least.
I recommend the Logitech MX ergo trackball.
The bottom part is hold by a magnet. You can stick it to the table board!
I'd wonder if a split keyboard like the Dactyl Manuform wouldn't be more comfortable instead.
$300 in material, $10,000 in medical bills and physical therapy.
hopefully this was a joke
