The front part of the chair under my legs went flat after just a few days and I started sliding off the front of the chair. I couldn't figure out why my back hurt so much then I compared my chair to my husband's. He doesn't spend as much time on his computer as I do so his was still inflated. I traded chairs thinking mine was a fluke but no his started going flat after one day of use. We returned both chairs and got a decent replacement. I guess these chairs were designed for someone who never actually sits just reclines back with their feet on the desk...
The shape and color design caught my attention. Also the price on sale was terrific! I sat in it and it was very comfortable and the raising arms are great too! Just a great computer chair for me.
