CORRECT SETUP
You can adjust the swivel chair in seat height, seat depth and
backrest inclination. This enables you to achieve an ergono-
mic sitting position. An upright sitting posture strengthens
your spine. Make sure that you place your legs at an angle
of slightly more than 90° and your feet completely on the
floor. The seat height is correctly adjusted when your knee is
slightly lower than your hip.
The length of your legs determines the
seat depth . It is
correctly adjusted when there is a distance of about three
fingers between the edge of the seat and the calf when the
pelvis is in very good contact with the backrest.
Adjust your
armrests
so that both shoulders are horizontal in
a relaxed position while your forearms rest on the armrests.
The arm angle should be at least 90°.
The width of the armrests depends on the width of your
shoulders. When adjusted correctly, your arms are close to
your torso while resting on the armrests. However, your free-
dom of movement must not be restricted.
Adjust the position of the
lumbar support so that the curva-
ture is at the level of the lumbar vertebrae, i.e., approximately
on the waistline. The lumbar support helps to relieve the
strain on your spine during long periods of sitting and sup-
ports your lower back in its natural shape.
