How to use

Adjust the seat height with the gas-lift lever so your feet rest flat on the floor and your thighs are roughly parallel to the ground.

Fixed armrests offer lateral support while you work; position the chair close enough to the desk to maintain a relaxed shoulder position.

For longer periods of sitting, periodically change posture and take short standing or stretching breaks. Use on hard or low-pile carpet for best caster performance and inspect casters and gas lift periodically for wear.
