Very fast delivery. Ware was well packaged. The building went fast and was not difficult. Price-performance is very good. Unfortunately, I can not forgive all the stars, since the chair is not the maximum specified. Achieved seat height of 86 cm. It measures, without sitting down, only 82 cm and if you sit on it he sinks still down. Since my desk has a height of 1.15 m the chair is a little bit too low. This should be corrected in the description. I'll keep this, they would have at the right specification of the max. Seat height of just 82 cm not ordered.
