Adjust the height of the lumbar support so that the
strongest tension of the seat fabric is at the level of the
lumbar vertebrae, i.e. approximately on the waistline. The
lumbar support helps relieve pressure on your spine when
sitting for long periods of time and supports your lower
back in its natural shape.
Your chair has a resistance mechanism that automatically
adjusts to your body weight. So, the backrest will always
provide you with ideal support as you move forward and
backward due to the automatic resistance. Generally, it is
healthier to move around while sitting, so set the back of
your chair to move. This extra moving can help prevent
negative effects from sitting all the time.
