I'm still amazed at how we lack both ergonomic and comfortable ways to use computers, it's usually just either one or the other, never both.
Imagine a large pillow that's shaped vaguely like human back should be when resting, which you could put on your bed to support your entire back, neck and head, at a slight incline. Then, add a keyboard support that can be moved around, alongside with one for mouse (or just a trackpad), as well as a VESA wall mount for a few monitors above the bed, angled so that you can look up at the screens directly, without putting too much strain on your eyes.
Essentially, it'd be the bed version of this: https://altwork.com/
And, because it'd be just a few pillows and some aluminum pieces for the mounts, it shouldn't break the bank like the linked item either. Otherwise, even with reminders to get up and walk around every hour, it always feels like my back is in the wrong position, regardless whether i'm sitting at a table with a chair, laying in bed with some pillows underneath or anything else. Even though i do stretches and daily exercise, the lack of truly ergonomic ways to work without having to constantly monitor my own posture (which will realistically never happen) feels like a detriment, or at least will become one in 20 years, when back issues start manifesting.
So here's my question: why are people so obsessed with office chairs and why don't we have such pillows be more popular, or just don't put more thought into working from bed?
