Operating Instructions

Your Marsail Office Desk Chair offers several adjustable features for personalized comfort:

Height Adjustment

To adjust the seat height, pull the lever located under the seat upwards while applying or releasing body weight. Release the lever at your desired height to lock it in place. The chair offers approximately 3.15 inches of height adjustment.

Tilt and Rock Function

The chair features a 90°-120° tilt angle. Use the same lever for height adjustment to engage or disengage the tilt function. A knob located under the seat allows you to adjust the tension of the tilt mechanism, controlling how easily the chair rocks back.

360-Degree Swivel

The chair is designed to swivel 360 degrees, providing easy access to different areas of your workspace without needing to move the entire chair.

Maintenance

• Cleaning: For the PU leather surface, wipe regularly with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the material.
• Inspection: Periodically check all bolts, screws, and moving parts to ensure they are secure and functioning correctly. Re-tighten any loose fasteners.
• Casters: Keep the casters free of debris (hair, dust, etc.) to ensure smooth rolling.

Troubleshooting

• Chair not adjusting height: Ensure the gas lift lever is fully engaged or disengaged as required. Check if the gas lift cylinder is properly seated in the base and seat mechanism.
• Chair is wobbly: Verify that all assembly bolts are securely tightened. Ensure the chair is on a flat, even surface.
• Casters not rolling smoothly: Inspect casters for trapped debris (hair, lint) and clean them.
• Squeaking noises: Apply a small amount of silicone lubricant to moving parts or joints if squeaking occurs.
