4. Operating Instructions
Converting to Sleeper Bed
To transform your sofa into a comfortable bed:
- Locate the fabric pull-out handles positioned beneath the front edge of the main seat cushions.
- Gently pull the handles outwards to extend the sleeper mechanism. The bed frame will slide out and lift into position.
- Ensure the extended section is fully locked into place for stability before use as a bed.


Adjusting the Backrest
The backrest offers three adjustable angles for optimal comfort (105°, 140°, and 180° flat):
- To recline, push the backrest forward slightly, then gently push it back to the desired angle.
- To return to an upright position, push the backrest fully forward until it clicks, then release it to the upright position.

Using Storage Features
Your sofa includes convenient storage options:
- Side Pockets: Each armrest features a side pocket for storing magazines, remote controls, or other small items.
- Chaise Storage: The chaise section can be lifted to reveal a spacious storage compartment underneath, ideal for blankets or pillows.

5. Care and Maintenance
Cleaning Velvet Fabric
- Regular Cleaning: Vacuum regularly using an upholstery attachment to remove dust and loose particles.
- Spot Cleaning: For spills, blot immediately with a clean, dry cloth. Do not rub, as this can damage the velvet pile. For stubborn stains, use a mild, water-free solvent or dry-cleaning product. Always test on an inconspicuous area first.
- Avoid Moisture: Do not saturate the fabric with water, as this can cause watermarks or damage.
General Care
- Avoid prolonged direct sunlight exposure to prevent fabric fading.
- Keep the sofa away from direct heat sources like radiators or fireplaces.
- Rotate seat and back cushions periodically to ensure even wear and maintain their shape.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Sofa feels too firm | New foam requires a break-in period. | Continued regular use will gradually soften the cushions to a comfortable level. |
| Parts do not align during assembly | Incorrect orientation of parts or misaligned holes. | Recheck the assembly instructions carefully. Ensure each part is oriented correctly before attempting to fasten. Do not force components. |
| Pull-out bed mechanism is stiff or stuck | Obstruction in the mechanism or lack of lubrication. | Ensure there are no objects obstructing the mechanism. If needed, apply a light silicone spray to the moving metal parts (avoiding fabric). |
| Backrest does not adjust smoothly | Mechanism obstruction or improper technique. | Ensure the backrest mechanism is clear of any obstructions. Apply gentle, even pressure when adjusting. |
