First I was positively impressed with speed of delivery. When I opened package there were no instructions on how to assembly the chair but found it quite easy to pull together. Chair meets the expectations, I find it very comfortable and adjusting options are nice to have. I use chair for 7 h a day. While the armrests get no use as they are set a too low and far away,  in overall I enjoy the purchase. It is not perfect chair but good enough to keep. Thanks
