Staples has some great chairs for ~$200. These fancy racing chairs that look like they're torn out of an actual car are pretty, but garbage when it comes to long-term comfort (they're designed for a couple hours of holding you still in a car, not for sitting in and gaming out for half the day). Office chairs are rated in hours, and I have two from Staples for $200-$250 each that are super comfy for many, many hours. The Staples Poynter chair is on clearance right now for ~$200 and I've sat in it for 8-12 hours at a time and even fell asleep in it. I'm not a fan of the pin-style lean lock, I much prefer the clamp style of my other chair, but its still a really good chair for the money
