Equally as expensive but I’ve found high quality office chairs are much better. Gaming chairs used to be fine for me until WFH. Every day after work my back was killing me, and I couldn’t ever game after work.
I got a relatively cheap ($500) office chair and it’s been fantastic. Ergonomic, fully adjustable in every way, and shaped for someone to sit in for 8 hours a day. Fantastic. I’d love an aeron but even used they’re over 1k and 500 was already a lot to spend on a chair for me.
