5. Maintenance
Proper care and maintenance will extend the life and appearance of your Bigzzia Gaming Chair.
5.1 Cleaning
- Faux Leather: Wipe the faux leather surfaces with a soft, damp cloth. For tougher stains, use a mild soap solution and then wipe clean with a dry cloth. Avoid harsh chemicals or abrasive cleaners, as these can damage the material.
- Base and Casters: Periodically clean the chair base and casters to remove dust and debris. This helps maintain smooth movement and prevents floor scratches.
5.2 General Care
- Tighten Fasteners: Regularly check and tighten all screws and bolts to ensure the chair remains stable and secure. Loose fasteners can lead to instability and wear.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the faux leather to fade or crack. Position the chair away from direct sunlight when possible.
- Weight Limit: Do not exceed the recommended weight capacity of 300 lbs (136 kg) to prevent damage to the chair and ensure safety.

- Verify that the gas lift cylinder is correctly installed and not damaged.
- Backrest Does Not Recline/Lock:
- Check the recline lever for proper engagement.
- Ensure no obstructions are preventing the backrest from moving freely.
