To chair himself, he is expensive but I think it was worth it! I've been the chair I use only rarely neck and back pain, the chair can be super adapt to those taking place on. There nothing wobbles and rattles nothing. Einzieges shortcoming is that the armrests have a mimimalen height difference, no idea why. That bothers me rarely. Why is always indicated that min. 2 people need to build the chair, I got him up alone in 30min. Have for my own tool does not use the enclosed, this made it easier to tighten the screws. Workmanship and materials are very good up high! Can only recommend weeiter this chair! For questions I am happy to help!
