- Connect Modules: Utilize the integrated connectors (screws and bolts) to securely link the modules together. These connectors are designed for easy engagement without the need for additional tools. Ensure each connection is firm to prevent movement.

Operating Instructions
Transforming to Sleeper Bed:
The pull-out sleeper module allows for easy conversion from a sofa to a comfortable bed.
- Locate Pull-Out Mechanism: Identify the pull-out straps or handles located at the front of the designated sleeper module.
- Extend Bed: Gently pull the mechanism outwards. The bed frame will slide out smoothly, and the mattress section will unfold.
- Retract Bed: To convert back to a sofa, push the mattress section back into the frame and guide the pull-out mechanism inwards until it is fully retracted and flush with the sofa.

Maintenance
Proper care will extend the life and appearance of your Belffin sofa. The velvet fabric is designed to be pet-friendly and easy to maintain.
- Regular Cleaning: Vacuum the sofa regularly using a soft brush attachment to remove dust and pet hair.
- Spot Cleaning: For spills, blot immediately with a clean, dry cloth. For stubborn stains, use a mild fabric cleaner specifically designed for velvet, testing on an inconspicuous area first.
- Removable Covers: The seat cushion covers are removable for easier cleaning. Follow the care instructions on the label for washing.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause fading. Position your sofa away from direct sunlight or use curtains/blinds.
- Fluff Cushions: Regularly fluff and rotate cushions to maintain their shape and even out wear.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Modules not connecting securely | Connectors not aligned or fully engaged. | Ensure modules are flush and connectors are properly aligned before pushing them together firmly. |
| Pull-out bed mechanism is stiff | Mechanism may need lubrication or is misaligned. | Check for any obstructions. Apply a silicone-based lubricant to moving parts if necessary. |
| Cushions appear flat or lumpy | Normal wear and tear; foam settling. | Regularly fluff and rotate cushions. If severe, consider replacing foam inserts. |
| Fabric shedding or pilling | Normal for velvet-like fabrics; friction. | Use a fabric shaver for pilling. Regular gentle vacuuming can help. |
