The fabric that constitutes the seat has stretched a little after two weeks of use and so I don't feel as supported by the seat. I'm only 167 lbs and the seat is sagging. The arm rests are quite hard. Elbows hurt regularly after prolonged desk work. No wonder this chair is routinely on sale. Should be another $50 cheaper than it is for this quality.
The lumbar support that I thought was the best feature of this chair is too high for me. I measured the length of the back part of the chair and it's 1/2 inch longer than the one my neighbor has. So I have to use a seat cushion. Other than that the chair is fine.
