Adjustable Headrest

Reclining Function
Activate the backrest's rocking function using the lever located under the seat. This allows you to recline and relax, transitioning easily from an upright working posture to a more relaxed position.
- Working Position: Maintain a 90° upright angle for focused work.
- Relaxation Position: Recline up to 115° for a comfortable break.

Flip-Up Armrests
The armrests can be flipped up 90°, allowing you to slide the chair completely under your desk when not in use. This feature helps save space in your home or office. The soft padding on the armrests provides optimal support for your arms.

Maintenance
- Cleaning: Wipe the mesh fabric and other surfaces with a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners.
- Inspection: Periodically check all screws and connections to ensure they are tight. Retighten if necessary to maintain stability and safety.
- Casters: Keep the casters clean from hair and debris to ensure smooth movement.
Troubleshooting
- Squeaking Noises: If the chair squeaks, check all bolted connections and tighten them. A small amount of silicone spray on moving parts may also help.
- Difficulty Adjusting Height: Ensure the gas lift lever is fully engaged or disengaged. If the issue persists, the gas lift may need replacement.
- Chair Feels Unstable: Verify that all components are correctly assembled and all screws are securely tightened. Ensure the chair is on a flat, even surface.
