So I finally got me for this office chair decided because I told myself, if I have to possibly annoy already on the acquisition, then that is mitigated by the relatively low price.
But so far there is no need to hassle at all. The chair was broken down into a stable acting carton, the items were well protected by foil or cardboard. Only the small bag with the screws and washers was torn, so that the content was partially right in the box. But there I could find everything again, and nothing was missing. The assembly instructions is completely without words; show only small pictures as it goes.
The building itself went quite smoothly and is also to accomplish good by just one person. Some holes are not quite fit, but the screws finally went into it yet.
Of course, and that should be clear to everyone, the chair is not necessarily the designer showpiece, but I am still quite happy. You sit very comfortable, even for several hours sitting has not yet been proven for me as a problem. The backrest could be a bit higher. Under certain circumstances, which is for tall people (over 185 cm) so not quite bearable in the long term. The rolls are easy to move through the laminate floor and left there any traces. In some other chairs I've read complaints that it would smell very strong; here is absolutely not the case. Moreover creaks or squeaks nothing.
So a strong buy recommendation is attached to this day. Whether that will remain permanently so, will of course only prove yet. I'm going to add an occasional update.
Update 06/08/2014: After about six months, and almost daily use, I can not detect any weaknesses. The chair is still as on the first day.
