Setup Instructions
Unboxing and Expansion
The Marsail modular sofa is designed for easy setup with no traditional assembly required. Follow these steps to prepare your sofa for use:
- Unbox: Carefully remove all sofa modules from their shipping boxes. The sofa arrives compressed in individual packages.
- Unwrap: Remove the protective plastic wrapping from each compressed module.
- Expand: Place each module in its desired location. Gently tap and fluff each part to encourage expansion and restore its elasticity.
Important: Allow the sofa modules to breathe and fully expand for approximately 72 hours to achieve optimal shape and comfort. The anti-slip particles on the base of each module ensure stability.

Operating Instructions: Customizing Your Sofa Layout
The Marsail modular sofa offers exceptional flexibility, allowing you to reconfigure its units to suit your space and needs. Each unit can be easily moved and rearranged to create various layouts.
Modular Configurations
- U-Shape: Combine all modules to form a large U-shaped sectional, ideal for spacious living rooms.
- L-Shape: Arrange modules into an L-shape, with or without an ottoman, for corner spaces.
- Separate Seating: Use individual modules as accent chairs or combine them to form smaller sofas with ottomans.
- Ottoman Use: Ottomans can be used as footrests, extra seating, or combined with other modules to extend seating.
Experiment with different arrangements to find the perfect setup for entertaining guests, relaxing, or family activities.

The configurations include a large U-shape, an L-shape with an ottoman, individual chairs and a sofa, and a compact sofa with two ottomans, showcasing the flexibility to adapt to various room layouts and needs.
Maintenance and Care
Cleaning Corduroy Fabric
- Regular Vacuuming: Use a soft brush attachment to gently vacuum the sofa regularly to remove dust and loose debris.
- Spot Cleaning: For spills, blot immediately with a clean, dry cloth. For tougher stains, use a mild fabric cleaner specifically designed for corduroy or upholstery. Test on an inconspicuous area first.
- Avoid Harsh Chemicals: Do not use bleach or abrasive cleaners, as these can damage the fabric.
- Air Dry: Allow any cleaned areas to air dry completely. Do not use heat.
Maintaining Cushion Shape
- Fluff Regularly: To maintain the cloud-like comfort and shape, regularly fluff and rotate the cushions.
- Even Use: Encourage even distribution of use across all sofa sections to prevent premature wear in specific areas.
Troubleshooting
Common Issues and Solutions
- Sofa Not Fully Expanded: Ensure sufficient time (up to 72 hours) has passed since unwrapping. Gently fluff and tap the cushions to aid expansion.
- Cushions Feel Too Firm: New foam cushions may feel firm initially. Continued use and regular fluffing will help soften them over time.
- Modules Shifting: Verify that the anti-slip particles on the base of each module are clean and making good contact with the floor. Ensure modules are placed on a stable, level surface.
