This chair is excellent! I sat at my wife's computer because mine was doing updates. After only 30 minutes my back was killing me. We went to Staples and checked the chairs selecting this chair. My wife is thrilled with the chair. It is extremely comfortable and gives her back the support it needs in all the key areas. I highly recommend this chair.
This is the best deal I found on all all mesh (back and seat) chair with enough adjustments to make it personable. It's very comfortable and I just hope it will last as long as the other chairs I've had in the past. Note: I took off the headrest; it wasn't adjustable and pushed my head forward.
