To maintain the appearance and longevity of your bonded leather chair:
- Regular Cleaning: Dust the chair regularly with a soft, dry cloth.

Hardware Check
Periodically check all screws and bolts to ensure they are tight. Retighten any loose fasteners to prevent instability and ensure safety.
6. Troubleshooting
| Problem | Possible Cause | Solution |
