How to use

Adjust the chair height so your feet rest flat on the floor and your knees form approximately a 90° angle.

Sit with your back against the contoured backrest to engage the lumbar support; make minor adjustments to the seat position and armrest height as needed. Lock the chair in a comfortable position before extended use and test caster movement on your floor type.

For longevity, avoid prolonged exposure to direct sunlight and clean upholstery with a soft damp cloth and mild detergent. Periodically check fasteners and the gas lift for secure operation. Use a suitable floor mat on carpeted surfaces to preserve caster function; adjust seating posture regularly to maintain ergonomic benefits.
