I went to OfficeMax and Staples and sat in every chair they had. The fifth-to-last chair I tried at Staples ended up fitting me perfectly. I think it was $100. I ended up turning the arms upside-down because I don't use them but they're still required to keep the back from breaking off.

Before going, I had researched the proper ergonomic position for a computer user. The important parts were legs at ninety degrees, chair can't put pressure on underside of your hamstring muscle (otherwise blood pools in your leg), lumbar support, and (for me, at least) vertical neck support allowing me to read the monitor while my neck muscles are completely relaxed. To complement this, I built a two-tier desk where my elbows are at 90 degrees while using the keyboard. I also have a wireless mouse[1] to use when sitting in a different position (because different positions are the key to being comfortable).

[1] The Perific wireless mouse http://www.thehumansolution.com/perificmouse.html which I just discovered is discontinued. sorry, and I really hope mine doesn't break.
