6.1. Height Adjustment
To adjust the chair's height, locate the lever on the right side, under the seat. Pull the lever upwards while sitting to lower the chair, or stand up and pull the lever to raise it. Release the lever at your desired height.

7. Maintenance
To ensure the longevity and optimal performance of your Marsail Ergonomic Office Chair, follow these maintenance guidelines:
- Cleaning: The manufacturer recommends dry cleaning for the fabric components. For general cleaning, wipe mesh and padded surfaces with a damp cloth and mild soap. Avoid harsh chemicals.
- Hardware Check: Periodically check all bolts and screws to ensure they are tight. Re-tighten if necessary to maintain stability and safety.
- Caster Care: Keep casters free of debris (hair, dust, etc.) to ensure smooth rolling. Clean them regularly.
- Gas Lift: Do not attempt to disassemble the gas lift cylinder. If it malfunctions, contact customer support.
8. Troubleshooting
If you encounter any issues with your Marsail Ergonomic Office Chair, please refer to the following common troubleshooting tips:
- Chair is Wobbly: Ensure all assembly bolts are securely tightened. Check that the gas lift is properly seated in the base and seat mechanism.
- Height Adjustment Not Working: Verify that the height adjustment lever is fully engaged and not obstructed. If the gas lift is faulty, it may need replacement.
- Recline Function Not Working: Check if the recline lock lever is disengaged. Ensure the tension knob is not overtightened, preventing movement.
- Casters Not Rolling Smoothly: Inspect casters for accumulated debris (hair, lint) and clean them thoroughly.
- Unusual Noises: Check all connections for tightness. Lubricate moving parts if necessary with a silicone-based spray, avoiding contact with fabric.
If these steps do not resolve the issue, please contact Marsail customer support.
