The chair is very comfortable and especially the upholstered armrests have it done to me. For long definitely sit ideal, the processing seems fine. However, the construction was a real tour de force, but I did not get screwed together the chair with safety and even with the help were all parts to bring only with brute force into position. The problem is that the backrest and the seat surface are screwed directly to one another via the armrests. First tighten the backrest and then the seat has worked for me, after several attempts, at least out to be a little easier.
