I can only advise against this product. It is by no means a prototype (which is now claimed since a few years to let the price seem a bargain), but absolutely inferior goods. The chair also sees in kind of good, but only until you first chips in the paintwork has -, which a light touch on the table edge. The cover is poorly processed and is torn at me at the seams after 14 days, the padding beneath emerged as billigster foam, which quickly sat is (barely 2 months elapsed with me). From the beginning, the chair has geknarzt and after about 4 months Wippsperre has no longer held and has blown repeatedly.
I've been buying absolutely regretted and brought the chair after only 6 months in the bulky waste.
Meanwhile, I have taken proper cash in hand and bought an ergonomic chair by Herman Miller, although costs 6 times as much, but it keeps well for 10 years and longer.
