5. Operating Instructions
The DERCASS Murphy Bed with Sofa is designed for easy conversion between its two primary functions.
5.1 Converting from Sofa to Bed
- Clear the Area: Ensure there are no obstructions in front of the sofa or the area where the bed will extend.
- Remove Sofa Cushions: Carefully remove the seat and back cushions from the sofa. These can be stored in the integrated storage box if available, or placed aside.
- Lower the Bed: Grasp the handles located on the front panel of the cabinet. Gently pull the bed downwards. The dual-piston mechanism will assist in a controlled descent.
- Extend Support Legs: As the bed lowers, flip the support legs down onto the floor to provide stable support for the bed frame. Ensure they are fully extended and locked into position.
- Position Mattress: Place your queen-size mattress onto the wood slats.



5.2 Converting from Bed to Sofa
- Remove Mattress: If desired, remove the mattress from the bed frame. For daily use, the mattress can often be left on the bed frame when closing, depending on its thickness and flexibility.
- Retract Support Legs: Fold the support legs back into their stored position.
- Lift the Bed: Grasp the handles on the bed frame and gently lift the bed upwards. The piston mechanism will assist in raising the bed back into the cabinet. Guide it smoothly until it is fully vertical and securely latched.
- Replace Sofa Cushions: Return the sofa seat and back cushions to their positions.
6. Maintenance
Regular maintenance will help prolong the life and appearance of your DERCASS Murphy Bed with Sofa.
- Cleaning: For the engineered wood and linen surfaces, wipe with a dry cloth. For spills on the linen, blot immediately with a clean, dry cloth. Avoid harsh chemicals or abrasive cleaners.
- Mechanism Check: Periodically inspect the dual-piston mechanism and all moving parts for any signs of wear or damage. Ensure all fasteners remain tight. Do not lubricate the pistons unless specifically instructed by DERCASS customer support.
- Wall Anchors: Regularly check the wall mounting hardware to ensure it remains secure.
- Weight Capacity: Do not exceed the maximum weight capacity of 600 LBS for the bed.

- Squeaking noises:
- Inspect all bolted connections and tighten any loose screws.
- Ensure the bed frame is level and properly aligned.
