Stool was poorly finished and settled rely heavily together. Metal splinters flew in building through the apartment. Backrest fit hardly turn on the seat because she was badly welded. After the stool was nevertheless built, we tested it. When lean is tilted immediately make back very high risk of accident! You can only use it to lean without, but this is not the intention. The walk is easy designed too small, so that you tip. Visually, it looks really great though, but for everyday use too dangerous! Can not imagine that something is admitted in Germany to me. Withdrawal went smoothly on manufacturers.
