6. Lumbar support adjustment (optional)
The height and depth of the lumbar support can
be adjusted to take account of the form of the
user's back, particularly in the lower back region.
To adjust the height, move the two controls at the
side of the backrest simultaneously up or down.
It's important that the integrated air cushion is not
yet filled with air. The inflatable air cushion (Air
Support) integrated within the backrest enables
the user to adjust the curvature of the lumbar
support. To do this, press the small pump at the
centre right under the seat until the curve of the
backrest feels comfortable.
Pressing the button located on the right-hand
side of the backrest deflates the cushion, making
the curve flatter.
