5. Maintenance

Proper care will extend the life and appearance of your office chair.

• Cleaning: For general cleaning, wipe the PU leather with a damp cloth. For tougher stains, use a mild soap solution and dry thoroughly. Avoid harsh chemicals or abrasive cleaners.
• Inspection: Periodically check all screws and bolts to ensure they are tight. Re-tighten as needed to maintain stability and prevent squeaking.
• Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the PU leather to fade or crack.
• Weight Capacity: Do not exceed the maximum weight recommendation of 300 pounds.

6. Troubleshooting

If you encounter any issues with your chair, refer to the following common solutions:

• Chair Leans to One Side: This can often be resolved by loosening the screws that hold the backrest to the seat, adjusting the backrest to be straight, and then re-tightening the screws firmly.
• Squeaking or Creaking Noises: Check all assembly points, especially where metal parts connect, and ensure all screws are tightened. Applying a small amount of silicone lubricant to moving metal joints (e.g., the tilt mechanism or gas lift connection) may help.
• Armrests Feel Loose: Regularly check and tighten the screws securing the armrests to the chair frame.
• Seat Cushion Feels Flat: While the chair uses high-density foam, prolonged heavy use can compress padding. Ensure you are within the recommended weight limit.

If the problem persists after attempting these solutions, please contact LEAGOO customer support.
