Several years ago, I bought an ‘executive chair’ from a local dealer for these folks:
They’re made to order and customized to your dimensions and preferences. They cost way too much. But mine has helped quite a lot with my back/ neck issues, as it’s both comfortable and reinforces proper posture. I’m happy with it.
This link now has a “HON” chair as its budget pick, not Ikea. Do you remember what the Ikea chair was called?
Edit: Oh nevermind, in the details for the HON exposure they mention the other choice, which was the Ikea Markus. They say the seat cushion on the Ikea Markus is poor in comparison. And the HON Exposure is cheaper than the Markus too!
I do have back, and other skeletal problems. For me, absolutely worth the price. I am also very short. It was one of the few adjustable into my range. They do adjust for bigger though, as my husband also got one (5’1" vs 6’) and we were both happy with how it adjusted for us.
For the “gaming” chair, with the caveat. My son, just got this:
He only recommends the Titan one, the others aren’t as supportive. Also he only recommends it if you are in the sweet spot for the suggested size. It is cheaper, lacking the adjustability for size. Looks like a modified car seat really. At 6’2" and weight in the 180s, it fits him well. But with the lack of adjustability, it may not if you are not close in build. He loves the recline feature with an ottoman for the feet. If you are the right size and want a chair/recliner mix, he also recommends it for that.
