5. Operating Instructions
The DERCASS Murphy Bed is designed for ease of use. Always ensure the area around the bed is clear before operating the mechanism.
5.1 Deploying the Bed (From Sofa to Bed):
- Clear the Area: Ensure there are no obstructions in front of the wall unit.
- Grasp Handles: Locate the handles on the front panel of the wall unit (which is the underside of the bed frame when stowed).
- Lower Bed: Gently pull the handles downwards. The dual piston mechanism will assist in smoothly lowering the bed frame. Guide the bed frame down until it is fully horizontal.
- Engage Support Legs: Flip the support legs down from the bed frame onto the floor to provide stable support. Ensure they are fully extended and locked into position.
- Place Mattress: If not already in place, position your Queen-sized mattress (max 6" thickness) onto the bed frame.

5.2 Stowing the Bed (From Bed to Sofa):
- Remove Bedding: Remove any pillows or heavy bedding that might obstruct the folding mechanism. The mattress can remain on the bed frame.
- Retract Support Legs: Fold the support legs back into their stowed position against the bed frame.
- Lift Bed: Grasp the handles on the bed frame and gently lift upwards. The dual piston mechanism will assist in raising the bed frame back into the vertical wall unit.
- Secure in Place: Continue lifting until the bed frame is fully vertical and securely latched into the wall unit. Ensure it is fully closed and stable.

- Mechanism Inspection: Inspect the dual piston folding mechanism for any signs of wear or damage. If you notice any issues, discontinue use and contact customer support.
