You get what you pay for when it comes to chairs. When choosing you also want to be able to sit in it at a desk. Places like Grand And Toy will have the good stuff, office grade stuff, meant to sit on for long duration. (referred to as a 24 hour chair). Downside is you can't really try it as those places tend to be order only.
So other best bet is Staples, and go try a bunch. Look for the more expensive ones as anything under $100 is not going to last.
I ended up buying a gaming chair, it's ok, but my only complaint is the arm rests are too far apart. When I'm typing I can't rest my arms on them, but if I'm gaming then I sort of can because my hand is on the mouse. I guess, that's why it's a gaming chair... lol. Probably like that by design.
