I'm trying to find a new chair since the one I have, which has lasted a few years, is finally breaking on me. I've been skimming posts here and haven't found anything that looks like what I'm looking for. I skimmed the megathread, I've done some other research, and I keep finding mixed differing opinions on everything and it's all just so confusing. I find a chair, and sources say it has these perks and these issues, and some stuff I don't like about it. I find something else, same deal.
Budget is a few hundred dollars (like $300-400, but I'm flexible if something fits my needs well and will last)
Average height and build at around 5'10" and 180 lbs
Western US
I'll be sitting in this chair for long hours many days each week for college work and gaming. I would like a headrest and smooth reclining, and I have ADHD so I tend to rock the reclining a lot and constantly shift my seating position. (The back was actually the fail point with my current chair)
