How to use

Adjust the seat height with the height adjustment lever so your feet rest flat on the floor and knees form approximately a 90° angle. Use the point-synchronous tilt control to set a comfortable backrest and seat angle; lock the mechanism in one of the available positions if needed. Sit with the backrest’s lateral pads supporting the lumbar area and the moulded seat stabilizing the pelvis. Use the chair on hard, level surfaces or on suitable floor protection when necessary.

Usage recommendations

For best ergonomic benefit, pair the chair adjustments with a correctly positioned desk and monitor: screen top at eye level, elbows supported at desk height, and regular short breaks to stand and stretch.
