How to use
Adjust the seat height so your feet rest flat on the floor and knees are approximately at a right angle. Set the armrest height to align with your desk or to support relaxed shoulders. Use the synchronised mechanism to find a comfortable recline and lock the chair in the desired position if needed. The knee roll on the seat supports the front thigh area; position yourself so that the padded edge does not press uncomfortably against the underside of the knees.
Usage recommendations
For prolonged use, combine correct seating posture with regular short breaks and small posture changes. Periodically check fastenings and adjustment mechanisms for wear if the chair is used under higher loads.
