Need help finding a good chair

[Droop]

Pretty much as the title states. I need help finding a badass chair for when I sit on my computer. I have some old completely worn out 9yr old chair. It sucks and my ass/back hurts after a good grind session.

I am looking for a super-comfy, high-backed ergonomic chair. I prefer to not have the arm rests on the side (If they could be taken off, that'd work). Of course swivel/adjustable needed.

Any suggestions? Any highly recommended? Budget isn't too crazy 100-200 bucks probably. Don't need no 700 dollar chair lol.
