The backrest offers 3 levels of adjustment to suit various activities from sitting upright to lounging or sleeping.
- To Recline: Gently push the backrest forward slightly, then push it backward to the desired angle. It will click into place at each level.

5. Care and Maintenance
Proper care will help maintain the appearance and longevity of your tiramisubest sleeper sofa.
- Regular Cleaning: Vacuum the velvet fabric regularly using a soft brush attachment to remove dust and debris.

- Avoid Harsh Chemicals: Do not use harsh detergents, abrasive cleaners, or solvents, as these can damage the fabric.
- Sunlight Exposure: Avoid prolonged exposure to direct sunlight to prevent fading of the fabric.
- Pet Care: The velvet fabric is designed to be pet-friendly and easy to clean. Regularly remove pet hair with a lint roller or vacuum.

6. Troubleshooting
If you encounter any issues with your sofa, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Sofa feels unstable or wobbly. | Loose connections or uneven floor. | Check and re-tighten all assembly screws and bolts. Ensure the sofa is on a level surface. |
| Difficulty converting to bed/chaise. | Mechanism obstruction or improper technique. | Ensure no objects are blocking the pull-out mechanism. Pull the seat cushion firmly and evenly. If the backrest is 5-level adjustable, ensure it's pushed with both hands; if one side won't lock, push again to reset. |
| USB ports not charging. | Power source issue or faulty cable/device. | Ensure the sofa is connected to a working power outlet. Try a different charging cable or device to rule out external issues. Do not overload the ports. |
| Backrest not adjusting smoothly. | Mechanism stiffness or misalignment. | Apply gentle, even pressure when adjusting. Ensure no fabric is caught in the mechanism. If the pull-out bed and cushion may misalign by 0.5-1.5 inches, adjust manually if needed. |
| Missing parts upon arrival. | Packaging error. | Contact customer support immediately with your purchase details for replacement parts. |
