CORRECT SETUP
You can adjust the swivel chair in seat height, seat depth
and backrest inclination. This enables you to achieve an
ergonomic 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 ad-
justed 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 arm-
rests. 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
freedom of movement must not be restricted.
Adjust the position of the lumbar support so that the
curvature 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
E
sitting and supports your lower back in its natural shape.
