1. Introduction
Thank you for choosing the DERCASS Queen Size Murphy Bed. This manual provides essential information for the safe assembly, proper operation, and effective maintenance of your new space-saving wall bed frame. Please read all instructions carefully before beginning assembly and retain this manual for future reference.
The DERCASS Murphy Bed is designed to maximize your living space by allowing the bed to fold away into a cabinet when not in use. It features a robust dual piston metal folding mechanism and flexible slats for mattress support, eliminating the need for a box spring.
2. Safety Information
- Wall Mounting is Essential: This Murphy bed MUST be securely anchored to a wall stud or solid structural element. Failure to properly anchor the bed can result in serious injury or property damage. Consult a professional if you are unsure about your wall structure.
- Assembly: Assembly requires two adults. Follow all steps precisely. Do not skip steps or use power tools excessively, as this may damage components.
- Weight Capacity: Do not exceed the maximum bed weight capacity of 600 lbs. This includes the mattress and occupants.
- Mattress Thickness: Use a mattress with a recommended thickness of 6-8 inches. Using a mattress outside this range may affect the bed's folding mechanism and safety.
- Children: Keep children away from the bed during assembly and operation. Do not allow children to play on or around the bed, especially when folding or unfolding.
- Clearance: Ensure adequate clearance around the bed when folding and unfolding to prevent injury or damage to surrounding furniture.
- Regular Checks: Periodically check all fasteners and connections to ensure they remain tight.

4. Setup and Assembly
Assembly of the DERCASS Murphy Bed requires careful attention to detail and adherence to the provided instructions. Two adults are recommended for safe and efficient assembly.
- Prepare the Area: Clear a spacious area for assembly. Lay out all components and hardware.
- Assemble the Cabinet Frame: Follow the step-by-step diagrams in the included assembly guide to construct the main cabinet structure. Ensure all connections are secure.
- Install the Piston Mechanism: Carefully attach the dual piston metal folding mechanism to the cabinet frame as instructed. This mechanism assists in the smooth operation of the bed.
- Attach the Bed Frame: Connect the bed frame to the piston mechanism and cabinet. Ensure proper alignment and secure all bolts.

- Secure to Wall: This is a critical step. Position the assembled Murphy bed against the desired wall. Locate wall studs and securely anchor the bed to the wall using appropriate hardware. This prevents the bed from tipping over.
- Final Checks: Before placing a mattress, test the folding and unfolding mechanism to ensure it operates smoothly and safely.


5. Operating Instructions
The DERCASS Murphy Bed is designed for ease of use. Follow these steps to safely fold and unfold your bed.
5.1. Unfolding the Bed
- Ensure the area in front of the cabinet is clear of obstructions.
- Gently pull on the handles located on the front panel of the cabinet. The bed frame will begin to lower smoothly.
- As the bed lowers, flip the support leg down onto the floor to provide stable support.
- Continue to lower the bed until it is fully extended and resting securely on the floor.

5.2. Folding the Bed
- Remove all bedding, pillows, and the mattress from the bed frame. The bed should be empty before folding.
- Lift the support leg and tuck it back into its stored position.
- Using the handles, gently lift the bed frame upwards. The dual piston mechanism will assist in the lifting motion.
- Continue to lift until the bed frame is fully retracted into the cabinet and the front panel is flush with the cabinet sides.


6. Maintenance
- Cleaning: Wipe the surfaces of the bed frame and cabinet with a dry cloth. Avoid using harsh chemicals or abrasive cleaners, which may damage the finish.
- Fastener Checks: Periodically inspect all screws, bolts, and connections. Tighten any loose fasteners to ensure the bed remains stable and safe.
- Mechanism Inspection: Check the dual piston mechanism for any signs of wear or damage. If you notice any issues, discontinue use and contact customer support.
- Slat Condition: Ensure all wooden slats are intact and properly seated in the bed frame. Replace any broken slats immediately.
7. Troubleshooting
- Bed is difficult to fold/unfold:
a. Ensure no bedding or objects are obstructing the mechanism.
b. Check if the support leg is properly retracted/extended.
c. Verify that the dual piston mechanism is correctly installed and not damaged. - Bed feels unstable:
a. Confirm that the bed is securely anchored to the wall studs.
b. Check all assembly fasteners for tightness.
c. Ensure the support leg is fully extended and locked when the bed is in use. - Squeaking noises:
a. Tighten all bolts and screws throughout the frame and cabinet.
b. Ensure slats are properly seated and not rubbing against the frame.
