Lumbar support
The curvature of the seat backrest can be ad‐
justed in such a way that it supports the lumbar
region of the spine. The lower back and the
spine are supported for upright posture.

the switch.
The curvature is increased/
decreased.
▷ Press the upper/lower sec‐
tion of the switch.
The curvature is shifted up/
down.
Shoulder support
Also supports the back in the shoulder area:
▷ Results in a relaxed seating position.
▷ Reduces strain on the shoulder muscles.
Active seat
Active adjustment of the seat cushion's con‐
tours reduces muscular tension and fatigue to
help prevent lower back pain.
