At first, I would have immediately awarded 5 stars. Sitting comfortably, seat firmly but not too hard. And of course, a great price. After about 2 hours, however, permanent seats, the seat cushion had been pressed all the way down. A slight pressure with the thumb and one felt already under the wood panel. When getting up you could see a well-formed depressed Delle. The more I then use the chair, the sooner the Posterung was floored. A spare seat did not help. Not that it was uncomfortable or you could feel the wood, but I think for continuous sitting at work, this chair is less suitable. For opportunity seater I recommend nevertheless fully him. The service was absolutely great !!! Sixbros
