I custom build mine out of marine ply and scrap scaffolding pipe (a few years ago, don’t have it anymore), it was handy at times but I ended up sitting down more than I expected, basically any time I had to really focus I’d sit down.

I think it’s because I have 30 years of body memory saying programming should be done sat down, I know others who’ve used them and like them so really it comes down to trying a cheap one and see how you get on.

I used a standing desk for a few years. Then I had ACL surgery and it wasn’t viable for a while. Standing desks are worth trying. Set one up on the cheap and give it a go for a couple of months. You’ll learn something and maybe it will be great for your work.

I tried going back, but putting the keyboard in my lap was a much better ergonomic improvement for me.

Get a desk that is adjustable, you don't want to be standing all of the time. I try to switch between standing and sitting each hour.

Been using 'Geek Desk' for 8+ years, I think there are other less expensive options available these days.

Sitting kills my back because I tend to slouch, standing all day makes my feet hurt.

The adjustable from ikea was too wobbly for me. I now just use boxes. The key is to switch , once you get used ti it you cant sit too long anyway.
