I did a LOT of research and tested a lot of chairs over a period of several months, and this chair is by far and away the best chair I tested for the price. Very thick and robust seat cushion that will not bottom out, no matter how long or what angle you sit at. controls are simple and reliable. chair is very sturdy and comfortable. Even good quality rollers that don't snag on carpet. Customer service from Chair Solutions is beyond excellent, and will answer questions for you that you didn't even know to ask! Highly recommended.
