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.
It was not complicated to assemble. We are having a some what dificult time in adjusting the chair to fit my wife. She is petite and I have to help her to get the proper tilt on the seat. There are 3 heights to the arm rest we could have used 1 more to a lower position.
