Operating Instructions

- Chaise Usage: The built-in chaise provides an extended lounging area. Its reversible design allows you to configure it to suit your room layout.

Maintenance and Care
Proper care will help maintain the appearance and longevity of your sectional sofa.
- Cleaning Code: WS - This fabric requires professional cleaning or spot cleaning with water-based or solvent-based cleaners. Test any cleaning solution on an inconspicuous area first.
- General Cleaning: Vacuum regularly using an upholstery attachment to remove dust and debris.
- Spills: Blot spills immediately with a clean, dry cloth. Do not rub, as this can spread the stain.
- Cushion Care: Rotate and flip removable cushions periodically to ensure even wear and maintain their shape.
- Sunlight Exposure: Avoid placing the sofa in direct sunlight for prolonged periods, as this can cause fabric fading.

Troubleshooting
If you encounter any issues with your sectional sofa, refer to the following common solutions:
- Wobbly Backrests: If a backrest feels wobbly, ensure it is fully inserted into its slot and that the connecting hardware is secure. Re-seat the backrest firmly.
- Sofa Sections Separating: If the chaise or sofa sections slide apart, verify that the connecting brackets underneath are properly engaged. Push the sections firmly together until the brackets lock.
- Uneven Seating: Rotate and flip cushions regularly to promote even wear. If the issue persists, check the suspension system underneath the cushions for any dislodged components.
- Squeaking Noises: Check all leg and frame connections to ensure they are tight. Loose connections can cause squeaking. Do not overtighten.
