Third Secretlab, it’s still pricy but far more affordable than HM, has all the lumbar support, and whilst it looks gamer-y it lacks the awful shoulders that makes it bad for you so it’s actually comfortable.
I had to WFH at my parents for 1 day the other week, couldn’t believe how bad my back pain got from 1 day in a crappy office chair. Their support was good too, my magnet head rest kept falling down so they sent me a brand new one
I think a Steam Deck is a better buy. It’s a little more pricy sure, but a lot more powerful and a LOT more games to pick from. And it docks great, I mostly play docked to my TV
