Now the negatives that led to the devaluation:
In pattern gray (fabric) / black (faux leather) has between Stzfläche and backrest, an offset of 2 cm, I find not so nice.
The assembly of the chair must be done by two people, which is not probably negative. However, if a screw is screwed because you forgot to cut into the socket threads, I think it's not so funny. Those who do not have the option must cut a M8 threaded the chair again completely disassemble, pack and send it back.
