Operating Instructions
Converting from Sofa to Bed
- Clear the Area: Ensure there is sufficient space in front of the sofa for the pull-out bed mechanism to extend fully.
- Locate Pull Handle: Find the integrated handle located at the front base of the sofa.
- Pull Out Bed: Gently pull the handle outwards. The bed mechanism will glide forward, extending the sleeping surface. Continue pulling until the bed is fully extended and locked into place.
- Adjust Backrest (Optional): The backrest can be adjusted to a flat position for sleeping.


The sofa bed converts to a full bed, providing a comfortable sleeping area.
Adjusting the Backrest
The backrest offers three adjustable positions:
- Sitting Position: Upright for comfortable seating.
- Lounging Position: Partially reclined for relaxation.
- Sleeping Position: Fully flat for use as a bed.
To adjust, gently push the backrest forward until you hear a click, then recline it to your desired angle. Repeat to cycle through the positions.

Side Pockets
The sofa bed is equipped with side pockets for convenient storage of small items such as remote controls, tablets, or magazines.

Care and Maintenance
- Cleaning Fabric: For general cleaning, vacuum the velvet fabric regularly using a soft brush attachment to remove dust and debris.
- Spot Cleaning: For spills, blot immediately with a clean, dry cloth. Do not rub. For stubborn stains, use a mild fabric cleaner specifically designed for velvet, testing on an inconspicuous area first.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause fading. Position the sofa bed away from direct sunlight or use curtains/blinds.
- Frame Care: Wipe the frame and legs with a soft, damp cloth. Avoid harsh chemicals.
- Mechanism Maintenance: Periodically check the pull-out mechanism for smooth operation. If it becomes stiff, a small amount of silicone-based lubricant can be applied to moving parts (avoiding fabric).
