Maintenance
Proper care will help maintain the appearance and extend the life of your sofa.
- Cleaning: Clean the couch with a damp towel. For deeper cleaning, use natural cleaning solutions such as vinegar and hydrogen peroxide. Always test any cleaning solution on an inconspicuous area first.
- Removable Covers: The sofa features removable covers. For best results, wash in cool water and dry on low heat.
- Cushion Care: Fluff and rotate cushions regularly to maintain their shape and even out wear.
- Spills: Blot spills immediately with a clean, dry cloth. Do not rub, as this can spread the stain.
Troubleshooting
If you encounter any issues with your Belffin sofa, please refer to the following common solutions:
- Modules not connecting securely: Ensure the metal brackets are properly aligned and fully engaged. Lift and reseat modules if necessary.
- Cushions appear flat: Allow up to 48 hours for cushions to fully expand after unpacking. Fluffing them manually can also help.
- Pull-out bed mechanism is stiff: Ensure no obstructions are blocking the mechanism. Apply gentle, even pressure when pulling or pushing.
- Squeaking noises: Check all connections to ensure they are tight. If the issue persists, contact customer support.
