Operating Instructions
The SITALA sofa offers versatile functionality as both a comfortable seating area and a convenient bed.
1. Converting to a Bed (Sliding Convertible Mechanism)
- Remove all loose cushions (back cushions and additional cushions) from the sofa.
- Locate the handle or mechanism at the front base of the sofa.
- Gently pull the seat forward. The sliding mechanism will extend the bed frame.
- Once fully extended, the integrated mattress topper will be revealed, providing a sleeping surface.
- To revert to sofa mode, push the extended section back into the sofa base until it locks into place. Replace cushions.

2. Using the Integrated Storage Chest
- The storage chest is located beneath the main seat cushion.
- Lift the seat cushion to access the storage compartment.
- Store items such as blankets, pillows, or other household goods. Ensure the weight is evenly distributed and does not exceed the compartment's capacity.
- Gently lower the seat cushion back into place to close the storage chest.
3. Adjusting Cushions
The back cushions and additional cushions are removable. The back cushions and additional cushions are also déhoussable (removable covers) for easier cleaning.
Maintenance and Care
Proper care will extend the life and appearance of your SITALA sofa.
1. Fabric Care (100% Polyester)
- Regular Cleaning: Vacuum the sofa regularly using an upholstery attachment to remove dust and loose debris.
- Spot Cleaning: For spills, blot immediately with a clean, dry cloth. Do not rub, as this can spread the stain. For stubborn stains, use a mild fabric cleaner specifically designed for polyester, testing on an inconspicuous area first.
- Removable Covers: The back cushions and additional cushions have removable covers. Follow the care instructions on the fabric label for washing or dry cleaning.
- Avoid Harsh Chemicals: Do not use bleach or abrasive cleaners, as these can damage the fabric.
2. General Care
- Sunlight Exposure: Avoid prolonged direct exposure to sunlight to prevent fading of the fabric.
- Heat Sources: Keep the sofa away from direct heat sources like radiators or fireplaces.
- Moving the Sofa: When moving the sofa, lift it rather than dragging it to prevent damage to the legs and frame.
- Memory Foam Mattress Topper: The integrated memory foam topper does not require special maintenance beyond keeping it clean and dry.
Troubleshooting
Here are solutions to common issues you might encounter:
- Difficulty Converting: Ensure no objects are obstructing the sliding mechanism. Check that the sofa is on a level surface. If the mechanism feels stiff, gently apply pressure while pulling/pushing.
- Squeaking Noises: Squeaking can sometimes occur from loose connections. Check and re-tighten all assembly bolts and screws.
- Cushion Flattening: Over time, cushions may compress. Rotate and fluff removable cushions regularly to maintain their shape and loft.
- Fabric Stains: Refer to the spot cleaning instructions in the Maintenance section. For persistent stains, consult a professional upholstery cleaner.
