The computer chair I was using caused shoulder and back aches. I went to Staples and sat in at least 15 chairs - I didn't really care what the price was I wanted a comfortable chair that didn't cause pain after a few hours. The minute I sat in this one I knew it was perfect. It supports my lower back it's very comfortable and on a recent 90 degree day the open mesh was appreciated. In addition to all that the price was surprisingly low and it was very easy to put together. You can probably pay a lot more but you won't find a better chair.
Back support feels great. Seat is full mesh and when you sit down in it it contours to you. It kind of squeeze you in. The head rest is too low for me. I am 5'9". It is at my shoulders and I can't adjust it high enough.
The chair wasn't available in the store so I ordered it and it arrived in two days. It was very easy to put together. I only needed my husbands help one time to lift the seat onto the base because it was too heavy for me to lift. The chair is very comfortable. The mesh back and seat allows for ventilation and there is a lumbar support that can be moved to where it fits you best.
