What should i prioritize when looking for a Gaming Chair?

So guys I am finally upgrading this wobbly office chair that i have had since college, and I'm now just realizing i have no idea what makes for a perfect gaming chair for a cozy set up.

I do know a whole lot of them are flashy looking and overpriced, but i also feel there have to be some pretty decent ones somewhere out there.

I am mostly just searching for something that is comfortable for long sessions, some gaming here and there and a little work from home time. Plus maybe the occasional 2am social media doom scrolling.

I've heard great things about chairs like The HERMAN MILLER Aeron, Blacklyte Athena Pro, DXRacer, Furgle etc. It only drives my confusion further, seeing as i am also on a budget.

What features should I be paying attention to when buying? Lumbar supports? Cushion thickness or mesh? Recline strength and angles? These are what Ai told me, but I want real users opinions.

Basically I want something that won’t make me sore and sweaty after a few hours, but also not look like something pulled from a spaceship cockpit.

If you've got personal recommendations that don't suck and won't hurt my back or break banks please share.
