1. Adjust seat height so that your thighs are either sloping
slightly downwards or level. While sitting on the chair, raise
your weight a little off the seat and lift the height adjustment
lever. To lower, sit very lightly on the seat and lift the height
adjustment lever.
2. Adjust seat depth (where applicable) to your preference. Ensure
at least a fist of clearance between the back of your knees and
the front of the seat.
3. G2: Adjust backrest height. Lift the back to raise in steps. After
reaching maximum height the back will drop back down to the
lowest position. G2E: adjust lumbar support height. Push the
lumbar support forward to release and move it to any of the
three height settings.
4. Adjust armrest height. Depress the button on the inside of the
arm and raise or lower to the desired height.
5. Adjust armrest depth. Push or pull the rear or front of the
armrest pad to slide it forwards or backwards.
6. Ensure tilt is not locked and adjust the tilt tension to suit your
preference. Turn the knob underneath the seat (G2) or to the
side of the seat (G2E). We recommend that the tilt is not locked
in normal use, for improved comfort and health.
7. Optional inflatable lumbar support: Squeeze the bulb to
increase the lumbar curve. Press the small button adjacent to
the bulb to release the pressure and decrease the curve.
