Operating Instructions
Converting to a Sleeper Bed
To convert the loveseat into a sleeper bed, locate the pull-out handle at the front base of the sofa. Gently pull the bed mechanism outwards until it fully extends and locks into place. Ensure the support legs are properly deployed for stability. To revert to sofa mode, lift the extended section slightly, push it back into the base, and ensure it is securely stowed.

Adjusting the Backrest
The backrest offers three adjustable angles: 108°, 135°, and 180° (flat). To adjust, push the backrest forward slightly, then recline it to your desired position. Release to lock the backrest into one of the preset angles. This allows for comfortable seating, lounging, or sleeping positions.

Maintenance
To maintain the appearance and longevity of your LUMISOL sofa bed, follow these guidelines:
- Cleaning: For general cleaning, vacuum the fabric regularly using an upholstery attachment. For spills, blot immediately with a clean, dry cloth. Avoid harsh chemicals or abrasive cleaners.
- Cushions: The seat and back cushions are not removable. Rotate and fluff pillows periodically to maintain their shape and even out wear.
- Frame: Periodically check all bolts and screws to ensure they are tight. Retighten as needed.
Troubleshooting
If you encounter any issues with your sofa bed, please consider the following:
- Difficulty in Conversion: Ensure no obstructions are blocking the pull-out mechanism. Apply even pressure when pulling or pushing the bed section.
- USB Ports Not Working: Verify that the sofa bed is properly connected to a power source. Check the USB cable for damage.
- Stability Issues: Confirm that all assembly hardware is securely tightened. Ensure the sofa is placed on a flat, even surface.
