The chair is comfortable but I found the following issues with it. During assembly three (3) of the four (4) holes used to attach the seat plate to the seat are perfectly alignment the forth one is about 0.25 inch off center. Right now my seat is held at three location instead of four. As long as I am not using the usage features I am secure. The other problem is the chair width it's designed for small frame people; it's not intended for overweight people or folks with large derrière.
I got this for my wife for our home office. She says that she loves how her body feels stable and supported in it. She says she feels she could sit for hours in the chair and feel o.k. Also as compared to office chairs she's sat in in the past the lever adjustments are very easy to use.
