6. Maintenance

6.1. Cleaning

To clean the chair, simply wipe it with a clean, damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these may damage the mesh fabric or plastic components.

6.2. General Care

• Periodically check all screws and bolts to ensure they remain tight. Re-tighten if necessary to maintain stability.
• Avoid exposing the chair to direct sunlight for extended periods, as this may cause fading or material degradation.
• Ensure casters are free of debris to maintain smooth rolling.

7. Troubleshooting

• Issue: Chair height slowly drops.
  Solution: This can sometimes occur with gas lift mechanisms over time. Re-adjust the height as needed. If the issue persists or the chair does not hold height at all, the gas lift may need replacement. Contact customer support for assistance.
• Issue: Chair is wobbly or unstable.
  Solution: Check all assembly screws and bolts, especially those connecting the seat to the mechanism plate and the backrest. Ensure they are securely tightened. Verify that the gas lift is properly seated in the base.
• Issue: Casters do not roll smoothly.
  Solution: Inspect casters for any trapped hair, dust, or debris. Clean them thoroughly. Ensure the chair is used on an appropriate surface (e.g., hard floor as recommended).
