® Use the whole seat surface
The anatomically shaped seat should be fully occupied.
Only then is proper contact with the supporting back-
rest assured.
early bird is also available with an adjustable seat tilt
and a sliding seat. These allow the seat to be adjusted
individually to suit any body size.
® Adjust the height of the seat precisely
The correct seat height means that the elbow joint
adopts an angle of about 90° when the forearms are
resting horizontally on the desktop. The knee joint
will also adopt an angle of about 90° when the feet
are flat on the floor. If your desktop is too high, and
cannot be lowered to a correct position, you need a
footrest with adjustable height and tilt.
® Adjust the backrest
Adjust the height of the lumbar support so that the
curvature of the backrest supports the spine in the
region of the third and fourth lumbar vertebrae (where
the forward curvature is greatest). This stabilises the
natural S-shape of the spine in every sitting position.
® Dynamic sitting
Dynamic sitting means changing your sitting posture
frequently, or in other words shifting as often as
possible between the front and rear sitting posture.
You should therefore adjust the backrest dynamically.
early bird is fitted with a “Similar” mechanism, which
allows you to adjust the pressure of the backrest
individually. The backrest and the seat therefore auto-
matically support you in every sitting position.
Healthy sitting is a question of attitude
