Why Build a DIY Murphy Bed? The Smart Space Solution
Murphy beds, also known as wall beds, are a fantastic solution for homes where space is at a premium. They are particularly brilliant for:
- Guest Rooms: Turn a rarely used guest room into a multi-functional space – an office, a craft room, or a home gym that can quickly become a comfortable sleeping area.
- Apartments and Small Homes: Maximizing every square inch is crucial in smaller living spaces. A Murphy bed can make a studio apartment feel significantly larger.
- Kids’ Rooms: Create more play space during the day by tucking away the bed.
- Home Offices: Maintain a professional work environment without sacrificing a place for overnight guests.
Beyond the obvious space-saving benefits, building your own Murphy bed offers several advantages:
- Cost Savings: Pre-made Murphy bed kits and fully assembled units can be very expensive. Building it yourself significantly cuts down on costs.
- Customization: You can design the cabinet to perfectly match your existing décor and choose the exact finish you desire.
- Satisfaction: There’s immense pride in building something functional, beautiful, and complex with your own hands.
Understanding the Components of a Murphy Bed
Before we dive into building, let’s get familiar with the main parts of a Murphy bed system. This will help you understand how it all works together.
A typical DIY Murphy bed system consists of a few key elements:
- The Cabinet: This is the main structure that houses the bed when it’s in the upright position. It’s essentially a tall, relatively narrow cabinet mounted to the wall.
- The Bed Frame: This is the frame that your mattress sits on. It needs to be sturdy enough to support the mattress and any sleepers.
- The Pivot Mechanism: This is the heart of the Murphy bed. It allows the bed frame to pivot up and down smoothly and safely. DIY kits typically use spring or gas piston mechanisms for assistance.
- Legs: When the bed is lowered, legs deploy from the bed frame or the cabinet to support the bed.
- Mattress Support: Slats or a metal grid that holds the mattress in place and allows for ventilation.
Gathering Your Tools and Materials: The Nailerguy Checklist
As your go-to guy for all things DIY and tools, I always emphasize having the right equipment. For a Murphy bed, you’ll need a good range of woodworking tools. Don’t worry if you don’t have everything – investing in a few key tools for a project like this is well worth it for future endeavors.
Essential Tools
Here’s what you’ll likely need. Safety first, always!
- Safety Gear: Safety glasses, ear protection, and work gloves are non-negotiable.
- Tape Measure: For accurate measurements.
- Pencil: For marking cuts and assembly points.
- Circular Saw or Miter Saw: For cutting your wood to size. A miter saw is great for precise, repeatable angles.
- Jigsaw: Useful for any curved cuts, though often not needed for basic designs.
- Drill/Driver: Essential for pre-drilling holes and driving screws. Consider one with multiple torque settings.
- Sander: A random orbital sander makes smoothing surfaces a breeze.
- Level: Crucial for ensuring your cabinet is plumb and level against the wall.
- Clamps: Various sizes will be incredibly helpful for holding pieces together while you drill and screw.
- Stud Finder: Absolutely vital for securely mounting the cabinet to wall studs.
- Optional but helpful: Router (for decorative edges), Table Saw (for more precise and repetitive cuts).
Recommended Materials
The type and quality of wood you choose will affect both strength and aesthetics. For a sturdy cabinet that can handle the weight and movement, hardwoods like oak or maple are excellent but can be pricier. Plywood (specifically furniture-grade or cabinet-grade) is a very popular and cost-effective choice. MDF is generally not recommended for structural components of a Murphy bed due to its susceptibility to moisture and potential for weakness over time.
For the Cabinet & Bed Frame:
- Plywood: 3/4-inch thick furniture-grade plywood is ideal. You’ll need several sheets.
- Lumber: 2x4s or 1x4s for internal framing and reinforcement.
For Hardware:
- Murphy Bed Mechanism Kit: This is crucial! You can buy kits online that include the pivot hardware, springs/pistons, and sometimes legs. These take the guesswork out of the most complex part. Brands like Rockler, Createz3D, or Amazon sellers offer various options.
- Heavy-duty Hinges: If your kit doesn’t include them for the cabinet doors (if you opt for them).
- Wood Screws: Various lengths (e.g., 1 1/4-inch, 2 1/2-inch) suitable for plywood and lumber.
- Wood Glue: For stronger joints.
- Lag Bolts: For securely attaching the cabinet to wall studs (ensure they are long enough to go through drywall, primer, and well into the stud).
For Finishing:
- Wood Filler: To fill any screw holes or imperfections.
- Sandpaper: Grits ranging from 80 to 220 for sanding.
- Primer and Paint or Stain and Polyurethane: To give your bed a finished look.
Example Material Estimate (for a Queen Size Bed)
This is a rough estimate. Always check your specific plans, as dimensions will vary.

Step-by-Step: Building Your Murphy Bed
This is a general guide. Always refer to the specific plans you are using and the instructions that come with your Murphy bed hardware kit.
Step 1: Prepare Your Workspace and Cut Your Materials
First things first, clear a large, flat workspace. Ensure good ventilation, especially when sanding or finishing. With your chosen plans in hand, carefully measure and mark all your plywood and lumber. Double-check every measurement before you cut. Accuracy here saves you headaches later!
Use your circular saw or miter saw to make clean, straight cuts. If you’re new to cutting plywood, consider using a guide rail with your circular saw for perfectly straight lines. Label each piece as you cut it to avoid confusion.
Step 2: Construct the Cabinet Box
The cabinet is the housing for your bed. It’s essentially a large, sturdy box. Most plans involve building a main carcass with a top, bottom, and two sides. For added rigidity and to provide mounting points for the pivot hardware, you’ll often attach internal cleats (strips of wood, usually 1×4 or 2×4) to the inside faces of the cabinet panels. These cleats will also be where the bed frame pivots and attaches.
Use wood glue and screws to assemble the cabinet panels. Pre-drilling pilot holes will prevent the plywood from splitting. Ensure all corners are square (90 degrees). Use clamps to hold pieces firmly in place while you assemble.
Step 3: Install the Cabinet Mounting Cleats and Pivot Hardware
This is where the magic starts to take shape. You’ll need to firmly attach the cabinet to your wall. First, locate wall studs using your stud finder. Mark their locations clearly on the wall where the cabinet will be installed. You’ll typically attach the cabinet to the wall using long lag bolts that go directly into the studs. A strong mounting system is paramount for safety.
Many plans call for mounting the cabinet structure to the wall before it’s fully enclosed, or they have separate mounting cleats that are secured to the wall first. Follow your plan meticulously here. The pivot hardware (part of your purchased kit) will also be attached to specific points on the cabinet’s side panels or internal cleats. Follow the manufacturer’s instructions for your specific hardware kit precisely.
Step 4: Build the Bed Frame
The bed frame needs to be robust. It’s usually constructed from 3/4-inch plywood for the panel surfaces that will hold the mattress and possibly 1×4 lumber for support and structure. The frame will be roughly the size of your mattress, often with a bit of extra room. You’ll also need to create a method for attaching the pivot hardware of your mechanism kit to this frame.
Ensure the frame is square and strong. If your plan includes slats for mattress support, install them now, spaced appropriately for airflow. Some designs use plywood with cutouts for air circulation, while others use a spring-loaded metal grid system that often comes with hardware kits.
Step 5: Mount the Bed Frame to the Cabinet and Install the Mechanism
This is perhaps the most critical assembly step. Carefully attach the bed frame to the pivot points on the cabinet using the hardware provided in your Murphy bed mechanism kit. This often involves aligning holes, inserting heavy-duty bolts, and ensuring everything moves freely.
Next, you’ll install the lifting mechanism (springs or gas pistons). This is what counterbalances the weight of the bed, making it easy to lift and lower. Be extremely cautious during this step. These mechanisms are under tension and can cause injury if not handled properly. Follow your kit’s instructions precisely. You might need a helper for this part.
Step 6: Attach the Legs
Most Murphy beds have legs that automatically deploy when the bed is lowered and tuck away when it’s raised. Some leg designs are built into the bed frame and pivot into place. Others might be a separate piece that attaches to the bottom of the bed frame. Ensure they are sturdy and designed to adequately support the bed when it’s in the horizontal sleeping position.
Some mechanism kits include legs as part of their package. Make sure they are installed correctly according to the kit’s instructions so they function smoothly. A common design has legs that extend from the bottom edge of the bed frame as it lowers.
Step 7: Finishing Touches and Testing
Once the mechanical aspects are sorted, it’s time for the polish.:
- Fill and Sand: Fill any screw holes or gaps with wood filler. Once dry, sand all surfaces smooth, progressing through finer grits of sandpaper (e.g., 80 to 120, then 220).
- Clean: Thoroughly clean off all sawdust with a tack cloth or damp rag.
- Prime and Paint/Stain: Apply your chosen finish. Use thin, even coats and allow each coat to dry completely according to the product instructions.
- Reassemble Small Parts: Reattach any decorative panels or trim pieces.
- Test the Mechanism: Slowly and carefully, test the operation of the bed. Lower it completely, then raise it. Check for smooth movement, proper leg deployment, and that the mechanism assists as it should. Listen for any unusual noises or binding.
If you’re adding cabinet doors or decorative panels to the front of the bed cabinet, now’s the time to install hinges and attach them. Ensure they hang plumb and operate smoothly.
Safety First! Critical Considerations for Your Build
Building a Murphy bed involves moving parts and significant weight. Safety cannot be overstated. Always prioritize these points:
- Secure Mounting: The cabinet must be securely fastened to wall studs. Failure to do so could result in the entire unit falling, causing severe injury and damage. Use lag bolts that penetrate deeply into the studs. A guide on finding studs from Fine Homebuilding can be very helpful.
- Mechanism Tension: Be extremely cautious when installing springs or gas pistons. They store a lot of energy. Follow the manufacturer’s instructions meticulously and wear safety glasses.
- Weight Capacity: Ensure your chosen hardware kit and frame structure are rated for the weight of your mattress and intended users.
- Smooth Operation: Test the bed’s movement repeatedly. If it binds, sticks, or feels unstable, stop and troubleshoot before use. Sometimes minor adjustments to alignment or hardware can solve issues.
- Clearance: Ensure there’s enough clearance around the bed when it’s lowered so no fingers or objects can get pinched.
Choosing the Right Mattress and Bedding
When selecting a mattress for your Murphy bed, keep a few things in mind:
- Weight: Heavier mattresses require stronger lifting mechanisms and can make operation more difficult. Lighter mattresses are generally easier to handle with spring or piston systems.
- Thickness: Your bed frame and cabinet are designed for a specific mattress thickness. Check your plans or hardware kit instructions for maximum and minimum recommended thickness. Too thick and it won’t close; too thin and it might not be comfortable.
- Type: Memory foam, hybrid, or latex mattresses usually work well. Innerspring mattresses can also be used, but check their overall weight and profile.
For bedding, consider using straps or ties to keep your sheets and duvet in place when the bed is raised. This prevents them from falling out or getting bunched up. Some Murphy beds have built-in straps for this purpose.
