It's actually pretty comfy. Here's a quick write up with pics: https://coursemaker.org/blog/create-affordable-lay-down-desk... (sorry for the pop-up)

The mouse is a little out of the way. Seems like have you to move to a workflow that you are almost entirely on keyboard? I would love that but just find that there is so much forced mouse interaction which I would like to avoid?

Just the photo, the mouse can be used no problem. I switch sides from time to time so shoulder doesn't get stiff.

I'm severely disabled from a back injury and I use this over my bed, with a vesa wall mount attached. I've also got a pair of joycons that I use as dual mice through steam https://www.amazon.com/gp/product/B0109Y3CCE/ref=ppx_yo_dt_b...

I'm having trouble understanding how that goes "over a bed" from looking at the photos.

With a 25" wall mount arm attached to the side of the tower, the screen hangs right over my bed. It does take a bit of balancing though depending on the weight of the screen and computer. I've got a 27" monitor on the side with the longer legs, and a large desktop on the opposite side near the ground

Re edit, that's not new ground though: aren't all desks 'standing'?!

True, there aren't transitive and intransitive versions of stand, but since desks stand by default, you can make assumptions about what a standing desk is. I really was not expecting a lay down desk to be something you lie down to use.

I agree with you; I read it the same way, I was just saying that 'standing desk' already annoyed me.

And damage does not scale linearly. I'd much rather have 50 200g rocks falling on my head than a single 10kg rock :)

Saying something obviously true makes it the "most HN" comment?

A friend once said “There’s all these studies about how bad sitting is for you. Now there are even studies about how bad standing desks are for you. Nobody ever says anything bad about laying down so I just try to do that as much as possible.” I still laugh. Perhaps true in part though.

IME it's not sitting or standing or lying down that's injurious, it's not moving . My pain to a large extent went away when I stopped staying so still. Now I change my posture on the regular, from leaning against the backrest to sitting away from it to taking little breaks to pace around a bit. 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 star…

Buy a standing desk and put a threadmill underneath.

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.

I am aware of this which is why I have always wanted one of those standing table treadmill combinations. I'm just not sure that I could actually work and concentrate while running... maybe if the table somehow compensated for the shaking caused by running on the treadmill. Or maybe one could use a VR headset instead of a regular display.

I had a diy one for a while. I found it really hard to type and walk. I can't imagine trying to type and run. 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.

I find it surprisingly easy. Are you able to properly rest your wrists on the table?

I thought about this same idea for a long time like 5 years ago. From hanging a monitor from the ceiling with string, to complicated wood framework such as the author. I finally realized that you can get about 90% of the way with a simple "medical table" ($50 on amazon) and a normal la-z-boy recliner.

I remember a couple years ago reading that to get roughly of 1080p of at VR headset distances would require the equivalent , from a pixel perspective, of several (I believe it was 8) standard sized desktop monitors. The implication of this was that we were a LONG way off from having that level of resolution so I would be very interested to know current state of the art. Also, this article about how different distance…

> to get roughly of 1080p of at VR headset distances would require the equivalent , from a pixel perspective, of several (I believe it was 8) standard sized desktop monitors 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 no…

The key metric is pixels per degree, which is going to come from both the field of view in VR as well as the monitor resolution.

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.

I work laying down at least one day per week. Its particularly good for sessions of long project work. Only a yoga mat, regular small couch cushions, and a small adjustable side table are required for my setup (to suspend my laptop from). Personally I use a wacom tablet and split, vertically arranged keyboard (koolertron), but I dont think those are really necessary. Touch typing is a must however, as you cant see the keys. Each half of the keyboard rests on my upper thigh, with one end on the floor, so my arms are in a very natural position resting by my sides. This setup alleviates all my back pain/tension, and is also easier on the tendons in my wrists and elbows. Working this way extends my maximum working days per week by at least one.

the thing is, why should it professionals be constructing their own ergo desks out of poverty. most professions that have physiological risks have the employer provide the safety gear... still stuff like this is getting expensive. im buying my sitting/standing desk second hand. still about 400E.
