The need to sit while working is a given. Be it at the desk or in front of your computer, sitting is not just for comfort, but for better productivity and concentration as well. If you're a gamer (like me), then chairs designed specifically for gaming are already on your short list. Then there are chairs that are ergonomically made for leaning back and taking those long naps after realizing that our bodies can't handle all those 12-hour workdays anymore!
What we have here is chairs specifically designed to be used with computers, when working or playing around with them.
