Allow me to sell you on my gaming chair that cured my back pain. I got a secret labs chair in 2020 because it was the only chair under a grand that could arrive in less than 3 days. It replaced a Herman Miller I used at work.

The Herman Miller can only be sat in one way. It's very light so climbing around it is just going to tip. You pretty much have to use it in the hr approved ergonomic position. Doing that for 8 hours a day just hurts. My gaming chair however is heavy enough that I can press my legs against the wall, or kneel on it without wobbling, or crosslegged. I can also sit with my neck on one handiest and my feet across another. Sometimes I lie with my legs at the head resting my head at the seat cushion.

The best sitting position is the one you don't stay in long, my gaming chair lets me do that and my back just stopped hurting. When the chair starts to age out I do plan on looking at ergo chairs as well, there seems to be a market for "weird chairs" that enable uncinventionak sitting but they seem to go a little too far as well, I do want to sit normally as well sometimes too. Gaming chairs really seem to hit my requirements of heavy, tall, wide and large armrests.
