Who does not want to spend much money, but still wants to sit comfortably, is right with this chair. The structure was quick and easy and the quality is very good. So far I could, after two months of use, yet find nothing negative. That the chair has a lower quality, as described in some reviews on similar chairs of this manufacturer, I can not confirm. Materials and workmanship make a good impression. For 100 euros you can in my opinion, just as expected an office chair like this. No more and no less. And that meets the Topstar California.
