Maintenance
Proper care will extend the life and appearance of your Korser sofa bed.
Fabric Care (Chenille):
- Regular Cleaning: Vacuum regularly using an upholstery attachment to remove dust and debris.
- Spot Cleaning: For spills, blot immediately with a clean, dry cloth. Avoid rubbing, which can spread the stain. Use a mild fabric cleaner designed for chenille, testing on an inconspicuous area first.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause fading.
Frame Care:
- Periodically check all bolts and connections to ensure they remain tight. Retighten as necessary.
- Avoid harsh chemicals when cleaning the metal frame; use a damp cloth.

Troubleshooting
If you encounter any issues with your sofa bed, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Sofa feels unstable or wobbly. | Loose connections or uneven floor. | Check and tighten all assembly bolts. Ensure the sofa is on a level surface. |
| Pull-out bed mechanism is stiff or difficult to operate. | Mechanism may need lubrication or be obstructed. | Ensure no objects are blocking the mechanism. Apply a silicone-based lubricant to moving parts if necessary. |
| Backrest does not stay in position. | Adjustment mechanism not fully engaged. | Ensure the backrest clicks firmly into one of the five positions. |
| USB/Type-C ports are not charging. | Power source issue or loose connection. | Verify the sofa is properly plugged into a working power outlet. Check the cable connections to the ports. |
