4. Maintenance
Proper care will extend the life and appearance of your Belffin sofa.
4.1 Cleaning Instructions
- For general cleaning, use a soft brush to remove dust and debris.
- For spills, blot immediately with a clean, dry cloth. Avoid rubbing the fabric when wet, as this can spread the stain or damage the fibers.
- The upholstery fabric is Terry, known for its durability.
4.2 General Care
- Avoid direct sunlight to prevent fading.
- Rotate cushions periodically to ensure even wear.
- Keep sharp objects away from the fabric to prevent tears or snags.
5. Troubleshooting
Here are solutions to common issues you might encounter:
5.1 Modules Separating or Sliding
Ensure that the built-in connection brackets on the underside of each module are properly engaged. Push the modules firmly together until the brackets lock into place. If issues persist, inspect the brackets for any damage.
5.2 Sofa Feels Too Firm
The sofa is designed with medium firmness for support and durability. Over time, with regular use, the foam cushioning will naturally soften. Continued use will help achieve a more comfortable feel.
5.3 Missing Parts or Damaged Components
If you find any parts missing or damaged upon delivery, please contact Belffin customer support immediately. Provide your order details and a description of the issue for prompt assistance.
5.4 Delivery in Multiple Shipments
