For those who want to know about that particular chair, it's a Zero-gravity Chair from Human Touch. I've got a much older version of that chair, and it's kinda busted, but when I have the floor space set up for it, it's an awesome recliner.
Big problem though: it rotates its full height to the horizontal so you have to have it practically in the middle of an area so it can lean back and not hit the wall.
This makes me wonder, would it be better for your posture to lay on your back, while looking straight up at a screen? I mean, go lay on a carpet floor or on your bed, flat on your back, with your knees bent for comfort. Then imagine a screen a couple of feet in front of your eyes, and a keyboard/mouse angled as well.
Wouldn't this give you perfect posture? It forces your back, neck and head to be straight. You can't lean forward because gravity forces your head into position. The above chair most likely offers some similar benefits since it's reclined so far back.
It felt great at first, but there was two major problems for me:
- with the laptop desk I had to slide under it each time I wanted to use the computer and grab the external keyboard, which isn't instantaneous like getting up/sitting down.
- I was waaaayyyy too sleepy lying on my bed. Had 2 minutes micro-naps all the time.
Right now I still often program in my bed, but with the screen vertical and at eyes height on the laptop desk, and my back resting against a bean-bag chair. It's much more comfortable than a standard desk-chair combination, I recommend people try it.
I avoid the use of a mouse, however, and my laptop is configured to be very keyboard-friendly, so there's also that to be taken into account. Using a mouse isn't impossible, but I'm much more performant without one.
That looks really comfortable, but it'd probably be annoying to get in and out of it, not only for the steepness of the chair, but also because of all the cords.
