I had ordered the chair for a friend. He said at first, the seat is almost horizontal and the chair thus unsuitable as a knee chair because the basin stand in a nearly 90 degree angle and sitting upright, with a simultaneous edition of the knee, is not possible. But then it turned out that he the chair still in the lowest position (the height is adjustable) had set. If the chair is then placed higher, the seat surface, the distance to Kniebablage is bigger and a comfortable, upright sitting position is possible prone. A Neagativebeurteilung this chair below, in English, shows that this user has the chair still in the lowest position, the seat is therefore just and the distance from the knee tray is too short. But that is only a setting error by the user.
