I think this is a proper first post: True-Innovations-Sport-Mesh-Mid-Back (Check office depot website for it) I just recently got this (for 80 dollars but still) and it is amazing. I can work 8 hours with it or game for 8 hours. Works great and never sweat unless it's 85+ and im shirtless leaning against it hard. Girlfriend was sweet enough to let me go pick out a chair and it's a solid win for me. Best thing you can do though is go to office depot/office max/whatever and try some out.
Teknion Contessa. Buy 1 chair for the next 15 years.....
if you are gaming it up for long hours get something that keeps your back straight and keeps you level with your desk this will protect you from pain. also get something nice and soft (you cant make a butt groove in something ridged!)
