The Verabreitungsqualität the office chair is very good! However, the chair has 2 major shortcomings: 1) The seat is to the sides a bit narrow and the padding to the sides insufficient. After some seat time you realize significant pressure points at the outer regions of the legs. 2) The back is bezgl. The fundamental adjustment top. However, the headrest is not high enough adjustable, so really only the neck is supported and coat the head back. With 187cm I am not yet at the top limit German sizes. Personally, I would recommend to a maximum 180cm chair people. In just something missing.
