As an alternative to the standard variants with a height of approx. 500mm, there is also a version available that is 100mm higher. The inclination of the backrest can be set steplessly through a range of 100° by turning the two hand wheels on both sides of the seat (the setting range can also be limited to meet customer specifications). Locking elements are not necessary thanks to the system’s self-locking function. On request, the forward-folding backrests can be supplied.
