How to use

Adjust the chair height using the gas spring lever until your feet rest flat on the floor and your knees form approximately a 90° angle. Position the lumbar cushion to support the natural curve of your lower back and attach the head cushion at a comfortable height for neck support. Use the rocker mechanism and backrest adjustment to find a comfortable recline angle and lock it when required. The 2D armrests can be moved to align with your desk and forearm position. Roll the chair on suitable flooring and avoid dragging it to prolong castor life.

Recommendations

For long sessions, periodically change posture and use the rocker function to relieve pressure. Remove cushion covers before washing and follow the 30°C wash instruction. Regularly check and tighten fasteners and keep castors clear of debris to maintain smooth movement and durability.
