Operating Instructions: 3-in-1 Conversion
Your DERCASS sofa offers three functional modes: Sofa, Chaise Lounge, and King-size Bed.
1. Sofa Mode
In its standard configuration, the unit functions as a comfortable three-seater sofa. Ensure the pull-out bed frame is fully retracted underneath the seat.

2. Chaise Lounge Mode
To convert to a chaise lounge, gently pull out the bed frame from underneath the seat until it extends approximately halfway. This creates an extended lounging surface.
3. King-size Bed Mode
To transform into a king-size bed, fully pull out the bed frame from underneath the seat until it is completely extended and locked into place. This provides a spacious sleeping surface.

Care and Maintenance
Proper care will extend the life and appearance of your DERCASS sofa bed.
- Cleaning: Wipe clean with a dry cloth. For spills or stains on the faux leather/velvet fabric, use a soft damp cloth and mild soap. Avoid harsh chemicals or abrasive cleaners.
- Cushion Care: The backrest and cushion covers are removable for easier cleaning. Follow care instructions on the fabric label if available.
- Frame Care: Regularly check and tighten any loose hardware to maintain stability.
- Sunlight Exposure: Avoid prolonged direct sunlight exposure to prevent fading of the upholstery.
Troubleshooting
If you encounter any issues with your sofa bed, refer to the following common solutions:
- Sofa feels unstable: Check all assembly hardware to ensure screws and bolts are tightened securely. Ensure the sofa is on a flat, even surface.
- Difficulty converting to bed: Ensure no obstructions are blocking the pull-out mechanism. Apply gentle, even pressure when pulling out or pushing in the bed frame.
- Squeaking noises: Identify the source of the noise. It may be loose hardware that needs tightening, or moving parts that could benefit from a silicone-based lubricant (avoid oil-based lubricants on upholstery).
- Stains on upholstery: Refer to the cleaning instructions in the Care and Maintenance section. Act quickly on spills.
If problems persist, please contact customer support for further assistance.
