The flat seat consists of foam in a plastic under-shell and features an additional knee roll. The patented Body Balance Tec® seat joint enables three-dimensional movement of the seat surface and thus freedom of movement in different directions.

The standard armrests can be adjusted in height and width. In addition, the office chair features a coat hook. The star base is made of polished aluminium. As standard, the chair is equipped with castors for soft floors.
