- Locate Handle: Find the fabric handle located at the front base of the sofa seat.
- Pull Out Bed: Gently pull the handle outwards. The bed extension will glide forward on its rollers.
- Extend Fully: Continue pulling until the bed extension is fully extended and locked into place, creating a flat sleeping surface.

6. Care and Maintenance
Proper care will extend the life and appearance of your sofa bed.
- Cleaning Velvet Fabric: For general cleaning, gently vacuum the velvet upholstery using a soft brush attachment to remove dust and debris. For spills, blot immediately with a clean, dry cloth. Do not rub. For stubborn stains, consult a professional upholstery cleaner.
- Frame Care: The reinforced hardwood frame requires no special maintenance. Avoid exposing the sofa to excessive moisture or direct sunlight, which can damage the frame and fabric.
- Cushion Care: The high-density foam and independent spring cushions are designed for durability. Rotate and fluff cushions regularly to maintain their shape and even out wear.
- Moving the Sofa: When moving the sofa, lift it rather than dragging it to prevent damage to the legs and frame.
