Discussion on: What are the things to consider while buying a computer chair?

I've spent quite a bit of time and money to decide on this list:

• Get a "task" chair not an "executive" chair, the former has removable arms. Take those off.
• Wheels, and if needed a chair mat, so the thing rolls easily.
• Only need two paddles: up/down and tilt/no-tilt.
• Keep shopping until you find one super comfortable in your price range.
