How to use

Adjust the seat height so your thighs are roughly parallel to the floor and your feet rest flat on the ground or on a footrest. Sit back so the lumbar area of the chair supports the lower spine. Use the height adjustment lever to raise or lower the seat when switching desks or users; make small adjustments until you reach a comfortable, neutral posture. For tasks that require forward-leaning, bring the chair closer to the work surface while maintaining lumbar contact.

Usage recommendations

For prolonged sitting, vary posture periodically and incorporate short standing breaks. Regularly check adjustment mechanisms and base stability, and keep the chair clean according to the manufacturer's surface care guidance to preserve appearance and function.
