But my everyday work is now done at a floor table. This posture brings a different level of activation energy, and it lets me keep moving around which is a clear advantage over most. It can present some of the same stresses as chair seating but it has more opportunities to relax. And unlike the standing or treadmill desks it easily works on a budget too - tape up a cardboard box and weigh it down and you have a temporary desk setup that will support most equipment. For a better surface with a finish and leg room, Ikea provides options, or you can get more specialized folding floor desks with angle adjustments and drawers off of Amazon.
Still, whatever works for you.
Beforehand I reworked my whole house to lift everything up and to make arrangements for computer use/entertainment while lying down.
I used an older iPad as a remote screen with a sturdy heavy use bendable arm to hold it, while just putting the keyboard on myself with the mouse down next to me which worked well enough. His mounted keyboard would probably have been an improvement, but using the mouse next to your body on a sturdy surface+mat worked really well.
I also made a temporary standing desk using boxes of paper to lift up my screen, keyboard and mouse, so that when I got tired of lying down I could stand for a bit.
All in all it turned out to be a really cheap and fast to implement solution that easily worked for the 3+ months.
I used a MacBook Pro clamped onto a bipedal stand, so the more elaborate scaffolded approach shown in the article wasn't necessary.
I've returned to it a few times since, because it's so damn comfortable.
