5. Operating Instructions
5.1 Pull-Out Bed Function
To transform your sectional sofa into a sleeper bed, locate the pull-out mechanism on the designated module. Gently pull the handle to extend the bed section.

6. Maintenance
Proper care will extend the life and appearance of your Belffin sofa.
- Cleaning: The plush corduroy fabric covers are removable and machine washable. Use cold water and dry on low heat. Avoid harsh chemicals or abrasive cleaners.
- Fluffing: Cushions may require occasional fluffing to maintain their shape and comfort, especially after prolonged use or shipment. Allow up to 48 hours for cushions to fully expand after unpacking.

7. Troubleshooting
- Sofa feels too firm: New cushions may feel firm initially. They will soften with use over time. Allow up to 48 hours for cushions to fully expand after unpacking.
- Modules are shifting: Ensure all connecting brackets between modules are properly engaged and secured.
- Pull-out bed not extending/retracting smoothly: Check for any obstructions in the mechanism. Ensure the module is on a flat, even surface.
- Fabric appears wrinkled or flattened: Gently fluff and pat the cushions. The plush corduroy will regain its texture.
