How to Make a Murphy Bed Mechanism

A Murphy bed, also known as a wall bed or fold-down bed, is a space-saving furniture solution that cleverly combines a bed with a cabinet or wall unit. The key to its functionality lies in its intricate mechanism, which allows the bed to fold up and disappear when not in use. While commercially available Murphy beds are readily accessible, building your own can be a rewarding and cost-effective DIY project. This article will guide you through the essential steps involved in constructing a Murphy bed mechanism.

1. Choosing the Right Components

The foundation of any successful Murphy bed mechanism lies in selecting the appropriate components. These components provide the structural support, movement, and safety features necessary for smooth operation and long-lasting performance.

The most critical components to consider are:

Hinges: Choose heavy-duty hinges designed specifically for Murphy beds. These hinges must be robust enough to support the weight of the bed and mattress, as well as withstand frequent use.
Support Brackets: These brackets attach to the wall and provide stability and support for the bed in both the folded and unfolded positions. They usually consist of two main parts: a wall-mounted bracket with a bolt-on arm and a corresponding bracket that connects to the bed frame.
Gas Springs: Gas springs, also known as gas struts, assist in lifting and lowering the bed. They provide smooth and effortless operation and reduce the manual effort required to raise or lower the bed.
Latches and Locks: These components ensure the bed remains securely in place when folded and prevent accidental unfolding.
Bed Frame: Select a bed frame that is compatible with the Murphy bed mechanism. The frame should be sturdy and lightweight to facilitate easy folding and unfolding.

2. Assembling the Mechanism

Once you have gathered the necessary components, you can begin assembling the Murphy bed mechanism. This process involves carefully attaching the hinges, support brackets, gas springs, and latches to the bed frame and wall.

The following steps outline the general assembly process:

Prepare the Wall: Ensure the wall is sturdy enough to support the weight of the bed and mechanism. You may need to reinforce the wall with additional studs or bracing.
Install Support Brackets: Attach the wall-mounted brackets securely to the wall using appropriate fasteners. The placement of these brackets is crucial for proper alignment and functionality of the mechanism.
Attach Hinges: Securely mount the hinges to the bed frame. The hinges should be positioned to allow the bed to fold up and down smoothly.
Install Gas Springs: Connect the gas springs to the bed frame and support brackets, ensuring proper alignment and tension. They assist in lifting and lowering the bed, making operation effortless.
Install Latches and Locks: Securely attach latches and locks to the bed frame and support brackets. These components keep the bed firmly in place when folded and prevent accidental release.

3. Testing and Adjusting

After completing the assembly, it is crucial to thoroughly test the Murphy bed mechanism to ensure it functions correctly. This involves raising and lowering the bed repeatedly, checking for smooth operation, and making any necessary adjustments.

The following adjustments may be required:

Adjusting Gas Spring Tension: If the bed feels too heavy to lift or drops too quickly, adjust the tension of the gas springs. You can usually do this by turning a knob or screw on the gas spring itself.
Adjusting Hinge Alignment: If the bed does not fold up or down smoothly, adjust the alignment of the hinges. Ensure the hinges are properly secured and the bed frame is level.
Adjusting Latch and Lock Placement: If the bed does not lock securely in place, adjust the placement of the latches and locks. Ensure they are correctly engaged and provide a firm hold.

By carefully following these steps and ensuring proper component selection, assembly, and testing, you can create a durable and functional Murphy bed mechanism that will provide a comfortable and space-saving sleeping solution for years to come.
