100% remote WFH. I also record videos, audio, drink tea and meditate here. 100% Darkmode 😎
I mainly sit on the floor, and occasionally stand, thanks to a Limber desk which easily lowers from standing to floor height. It was not easy at first but has worked wonders on my back and hips over time, vs a chair.
Lack of a back support feels difficult at first due to not being used to it, but long term it does not seem to be the case. The body only gets stronger and less painful in the long run (well at at least about 14 months so far). I do sit on a rather thick firm meditation cushion, not directly on the floor (yet). I got about an inch closer to the floor after 1 year, with about 2-3 inch to go until being bum flat on floor. I find it better than standing up.
So the trick is to actually sit on a cushion or bolster high enough so that your lower back gets its natural lumbar slight curve and not rounded or slouched, and your knees get lower than hips, then transition gradually over many months to get closer to the ground. Everything very slowly gets stronger. It feels really good eventually.
It makes me think a backrest is a kind of "orthosis" that causes the body to become completely reliant on it and weaken. Like wearing a plaster cast too long.
Sure, the light is actually a LED video light panel that I use for videos, but it doubles as a desk lamp. I set it to warm white and bounce it off the wall and dim my screens to roughly match the brightness. I don't have big eyestrain issues but I certainly find this more comfortable to look at in the evening. I like it better than having all the room lights on too.
