Regular padded office chair, probably 15 years old by now.
I regret taking apart the hand rests and tossing them, on the hunt for replacement ones now.
I was looking into these ergonomic mesh chairs but this video turned me off them:

TL;DW they're mostly designed to be comfortable when you're sitting properly, and that's not me.
So now that I've decided to stick with my chair I'm going to do some maintenance
>clean the fabric
15 years of stains and gunk, any amount of cleaning would be good.
>de-squeak
I've already lubed it up a couple of times but it never lasts too long because the only oil I have around is some thin silicone spray, gonna get some heavy duty grease (white lithium?) and treat it right.
>handrests
just gonna get some used ones, on the hunt for chairs people throw out or give away.
