Frame Care:
Wipe the metal frame with a damp cloth to remove dust and dirt. Avoid using abrasive cleaners or harsh chemicals, as these can damage the finish. Ensure the frame is dry after cleaning to prevent rust.
General Care:
- Vacuum the fabric regularly to remove dust and debris.
- Address spills immediately by blotting with a clean, dry cloth.
- Avoid placing the sofa-bed in direct sunlight for prolonged periods to prevent fabric fading.
5. Troubleshooting
Difficulty Transforming:
- Ensure no objects are obstructing the frame's movement during conversion.
- Check that all hinges and moving parts are free from debris. If movement feels stiff, a small amount of silicone spray can be applied to the joints.
Fabric Stains or Damage:
- For stains, refer to the care label on the fabric cover for specific cleaning instructions. Treat stains promptly.
- If the fabric is torn or significantly damaged, contact your retailer for advice on replacement covers or repair options.
