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

It is normal for the modular sofa to be shipped in several boxes, which may arrive on different days. Please allow a few extra days for all packages to be delivered before contacting support about missing components.
