6. Maintenance
Proper care will help maintain the appearance and functionality of your chair.
- Cleaning: Wipe the PU leather surfaces with a soft, damp cloth. For stubborn stains, use a mild soap solution and then wipe dry. Avoid harsh chemicals or abrasive cleaners.
- Moving Parts: Periodically check the casters, gas lift, and recline mechanism for smooth operation. If any part becomes stiff, a small amount of silicone-based lubricant can be applied, avoiding contact with the upholstery.
- Fasteners: Every few months, inspect all screws and bolts and retighten them to ensure the chair remains stable and secure.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the PU leather to fade or crack.
