Have received the office chair about 2 weeks ago and were quite satisfied with the goods at the beginning. Unfortunately, we noticed already in the assembly are not really impeccable quality of the article: sharp corners of the plastic panel, which at various points can be even slightly push without effort, thus indicating to thin material. We built the chair, despite the rather meager manual together right fix. But since we still wanted to grow the backrest, we discovered that a thread was not incorporated vertically into the body of the chair. Thus it happened that we started when tightening the screw, the thread of the "anchor". Then the screw was no longer in front and turn back, and we had the chair at Amazon return (very inconvenient!). Because I thought that this was probably a Monday model, I wanted to give the manufacturer a chance and ordered a replacement item. In this the problem with the screw God did not occur to thank, but the sharp edges and thin plastic panel already. Nevertheless, one has to say that this chair is quite a convenient and good-looking, which you can buy quite when the one, my Erachtung after, not so good processing does not interfere.
