"This chair is very comfortable and looks very nice," said a satisfied shopper. "It supports my back very well and the seat cushion is one of the better ones — it is soft, but dense enough that it will not bottom out to the point that you will feel the hard bottom surface through it."

"I work at my desk for several hours every day. My old chair was uncomfortable after an hour; This chair is very comfortable, even after sitting in it for several hours," said a happy customer. "It requires assembly but the instruction were good and it was easy to assemble."

Raved a five-star fan: "Great chair for the money! I hesitated between this chair and another, much more expensive one. I chose this one because of the breathable lightweight material — mesh. In California, that's important. Wow! The comfort and support for my back, and the adjustment to my parameters exceeded all expectations. I didn't expect to get such a cool ergonomic chair for this price."
