How to use

Sit with your back against the mesh backrest and adjust the pneumatic lever to set the seat height so your feet rest flat on the floor and your knees form approximately a 90° angle. Set the headrest height to support the base of your skull and adjust the lumbar support if available to match the inward curve of your lower back. Use the armrests to rest your forearms so shoulders remain relaxed. Move the chair on castors as needed for short repositioning within your workspace.

Recommendations

During height adjustment take care to avoid sudden movements; there is a possibility of tipping over if the chair is tilted or if weight is not evenly distributed while changing height.
