Eh. Ergonomically speaking, using a bed desk puts you in a poor posture for extended computer work. Your back is unsupported, your neck is craned downward, and your wrists and arms are likely unsupported as well. There might be some weird disruption of the brain's conditioning that the bed is for rest as well if you do this too much. Lotta people have a tough time falling asleep because of an inability to mentally "switch off" at night. Keeping work restricted to a desk area is a sort of magical mental separation that I like.

I work lying down with a pillow acting as a desk for my keyboard (I don't have to look at the screen as I use screen reader software) so I guess I don't have to worry about it. It hurts my back sitting for long hours so I found lying down to be more comfortable working from home :)

I had a bed desk with the monitor above me for about 9 months. It was a total gamechanger and I would definitely recommend it if you have the space. I don't have the space anymore, but one day I want to go back to that method of working.. no back or neck pain, more concentration

Likely the issue is related to circulation (or lack thereof), lack of exercise in key core muscle groups (including the heart), and nerve inflammation in spots where there is consistent pressure.

Notably, the bed is much worse for this than sitting (see bed sores, compartment syndrome, etc).

Way late on this and maybe this was a joke. But for what it's worth - the study categorizes sitting and lying down in the same category (sedentary).

if augmented reality glasses continue like they are, this could be very possible in the near future. an infinite array of displays as you lay down. a virtual keyboard might take some time to get used to though

My setup was modeled after the precogs’ workstations in Minority Report.
