Backrest height
The backrest can be
adjusted to support the
lower back. The curve
in the backrest should
be in the lumbar region
– approximately at belt
height – and you should
feel it supporting your
weight.
To adjust
Turn the knob of the
back clasp to the left as
far as it will go. While
seated, push the back-
rest up- or downwards
in the desired position.
Then turn the knob back
to the right.
