This office chair is not for people who want to> 4 hours / day sit on. Especially not if you weigh more than 90 kg. The mechanics and metal plate squeaked and wobbled after just 4 weeks of use. I wanted to return the chair, but the dealer has given me a replacement disk. This replacement disk to have been apparently needed because the paint on the movable hinge exhibited strong Abnutzungserscheinugen. In addition, I was in a large cardboard box nor any Mange delivered "rubbish", I must dispose irgendie. The new metal plate brought expected no improvement, so that the chair is no longer used after only 3 months. An absolute bad buy, alas! The padding of the seat is only a few mm, the artificial leather looks cheap and poorly finished. If this chair should be on offer again, I can only advise of a purchase.
By the way: My flaws information from the supplier were not really taken seriously. Lapidar you have made to the high sales figures and said that most customers were satisfied.
This seller I will in future no longer guaranteed anything buy !!!
