Reclining Gaming Chair with Footrest

I'm in Germany and looking for a new desk chair, but I think my requirements are the opposite of what most ergonomic chair recommendations focus on. For years I sat on a very basic dining/living room chair (photo attached). It had a flat seat, a mostly flat backrest, no lumbar support, no armrests, and no ergonomic features whatsoever. Despite spending a lot of time at my desk, I never had any back issues. Recently I bought a ProtoArc EC200. At first I thought the lumbar support was the problem, but I completely removed it and I'm still having issues. The chair feels like it locks my pelvis and lower back into a specific position. I feel like I sit too deep in the corner between the seat and backrest, forcing my pelvis forward and creating a lower-back curve my body simply doesn't want. The weird part is that I usually don't feel pain while sitting. Instead, I get stiffness and lower-back pain the next day, often lasting for days. What makes this especially strange is that I've never had issues with hard seating. University lecture halls, trains, waiting rooms, benches, even sitting on concrete slabs for hours have caused me much less discomfort than this chair. My current theory is that highly contoured ergonomic chairs simply don't suit me. Yet it seems like almost every modern office chair is designed this way. I'm 187 cm (6'2") and about 80 kg (176 lbs). Things I don't care about: \-fancy ergonomics \-aggressive lumbar support \-mesh backs \-lots of adjustments \-armrests What I think I want: \-neutral geometry \-a relatively flat seat and backrest \-freedom to move around \-a sturdy structure that doesn't creak \-something I sit on, not in I'm even considering a Secretlab Titan Evo because many complaints about it seem to be that it's too flat, too firm, and not ergonomic enough—which honestly sounds closer to what I might want. One more thing: I'm in Germany. The used market for premium office chairs is nowhere near as good as many US-based recommendations assume. Most used Herman Miller / Steelcase listings I've found are either rare, heavily worn, or still surprisingly expensive, so I'd appreciate recommendations for chairs that can realistically be bought new in Europe as well. Has anyone had a similar experience and ended up happier with a more neutral chair?

Ordered Thursday, came today. Got the black cloth regular size one with no extra accessories. Aside from being really heavy it's great! Huge basic instruction sheet (really all you need, but it has a qr code to a more detailed set of directions). AMAZING packaging with a "tool kit".1 9 screws total (4 to remove and reinsert to attach the back, 4 to attach the base, and one to remove from the locking plastic for the recline). Very easy to assemble most everything is METAL except for the magnetic pop on stuff. This chair is much nicer than the others that give you a tiny allen wrench a 2 sheet piece of crap instructions with plastic caps to cover screw holesthat pop off. Very nice and firm compared to my old respawn that went flat to metal on the seat, cracked and every piece wiggled no matter how tight the screws were. Quite impressed with it, so far feel it's worth the money. Would recommend!

Hello, I wanted to ask if anyone could help me find a office chair. I'm \~5'7 ft (upper end of 5'6 ft) at 145 lbs with a budget of $325 USD max (excluding shipping and tax.) I'll buy both new and used if possible. I've heard of brands like Steelcase but I want to narrow down the selection. I've tried looking for local listings on Facebook Marketplace (United States east coast) though I didn't see many listings. I'm coming from a Respawn gaming chair (rookie mistake?) and all of the pleather has flaked off making the chair very uncomfortable to use (the holes in the pleather is scrapping on my skin) and the chair is a bit oversized too. I primarily spend \~4 to \~7.2 hours using my workstation programming (lots of typing) and playing video games (moving my right wrist a lot). I've already cooked my right wrist from a bad chair and technique so hopefully I can mediate that with a proper chair (though it might be beyond reversal.) I do not have any pets.
