3. Operating Instructions
The modular design of your Belffin sectional sofa allows for flexible arrangement to suit various needs and room layouts. Each module is designed for easy reconfiguration.
Reconfiguring Your Sofa:
To change the sofa's configuration, simply disconnect the modules by unlatching the connectors located underneath. Rearrange the modules as desired and re-secure them using the connectors. The lightweight nature of the individual boxes during delivery also translates to easier rearrangement of the modules once assembled.

Utilizing Storage:
Each seat and ottoman module features a hidden storage compartment. To access, simply lift the top cushion. These compartments are ideal for storing blankets, pillows, books, or other living room essentials, helping to keep your space organized.

4. Maintenance and Care
Proper care will extend the life and maintain the appearance of your Belffin modular sectional sofa.
General Cleaning:
- Dust and Debris: Regularly vacuum the sofa using an upholstery attachment to remove dust, crumbs, and pet hair.
- Spot Cleaning: For spills, immediately blot with a clean, dry cloth. Do not rub, as this can spread the stain.
- Wipe with Damp Cloth: For general cleaning, wipe the velvet fabric with a damp cloth. Avoid excessive moisture.
- Pet Hair: The velvet exterior is designed to be easy to clean from pet hair; a lint roller can be very effective.

Cushion Care:
The sofa features resilient cushions with supportive pocket coils and soft multi-foam layers. While the cushions are designed to maintain their shape, occasional fluffing can help preserve their comfort and appearance.
