SEAT HEIGHT
The angle of the thigh and calf should range from a right angle to a slightly open
angle. The seat height should be set at the level of the hollow of the knee. Both feet
should be make contact with the fl oor across their entire length.
LOWERING SEATING SURFACE
Pull the control handle upward while seated and release at the desired position. Pay attention
to the risk of getting caught between the base and the seat workings when lowering the seating
surface.
RAISING SEATING SURFACE
Take pressure off the seat, pull the control handle upwards, and release at the desired position.
ADJUSTING THE SEAT INCLINATION
To support the physiologically correct pelvic tilt, you can adjust the seating surface either with
permanent contact or at any tilt. The tilt ensures the desired straightening of the spine in its
natural double-S position.
SEAT INCLINATION WITH PERMANENT CONTACT
While seated, push the control handle forward and then down. The seating surface tilts in
accordance with the shifting body weight and calf position. Deactivate it by pulling the control
handle upwards.
INDIVIDUAL ADJUSTMENT OF THE SEAT INCLINATION
While seated, press the control handle forward and determine the desired tilt by shifting your
weight/thigh position, and then release the control handle.
