If you’re working with a small room, a Murphy bed can change how you use it. The bed frame and mattress fold up against a wall or into a cabinet-style enclosure when they are not needed, freeing floor space for an office, living area, workout space, or guest room. The key is choosing a model that fits your room, mattress, wall construction, and everyday routine.
Quick Answer
A Murphy bed, also called a wall bed, is a bed that pivots from a vertical or horizontal stored position into a normal sleeping position. A spring or gas-piston system may help balance its weight. Wall-mounted models must be installed exactly as the manufacturer specifies, and mattress size, thickness, and weight limits vary by model.
Key Takeaways
- A Murphy bed folds into a wall-mounted cabinet or enclosure so the same room can serve more than one purpose.
- Lift systems vary; common designs use counterbalanced springs or gas pistons rather than one universal mechanism.
- Mattress thickness and weight limits are model-specific, so check the bed manufacturer’s specifications before buying a mattress.
- Vertical and horizontal models require different amounts of wall width, ceiling height, and open-floor clearance.
- Correct structural anchoring and assembly are essential for wall-mounted units because an improperly installed bed can create serious impact or crush hazards.
What Is a Murphy Bed?
A Murphy bed is a type of wall bed that stores upright or sideways when it is not being used. Instead of permanently occupying the room like a conventional bed, its mattress and platform move with the bed frame into a cabinet or wall-side enclosure.
That makes it useful in studios, home offices, guest rooms, and other multipurpose spaces where recovering floor area during the day matters. When closed, the visible face may look like cabinetry, paneling, shelving, or another furniture element.
A Murphy bed does not make the room physically larger, but storing the sleep surface vertically can return much of the bed’s normal footprint to everyday use.
The name is associated with William L. Murphy. His U.S. patent for an improvement in a “disappearing bed” was filed on April 3, 1911 and published on June 18, 1912. The patent describes an improved way to move and conceal a bed rather than establishing that all earlier disappearing-bed concepts began with that patent. You can view the 1912 William L. Murphy patent record.
Modern Murphy beds are more varied than the early designs. Depending on the manufacturer, you may find vertical or horizontal orientations, spring-assisted or gas-piston mechanisms, built-in desks, shelves, sofas, lighting, and storage. Mattress requirements also differ from one system to another.
How a Murphy Bed Folds Into the Wall
A Murphy bed rotates around pivot points near the head or side of the frame. A counterbalancing mechanism offsets part of the combined weight of the bed platform, front panels, and mattress so you do not have to lift the full load by hand.
Some beds use gas pistons, while others use counterbalanced springs. Both approaches can provide controlled movement when properly engineered and installed. The exact operation, tension adjustment, locking method, and acceptable mattress weight depend on the hardware. Manufacturers such as Wilding Wallbeds document both piston and spring lift systems.
When the bed is lowered, legs or another support structure carry the outer end of the platform. When it is raised, the mattress remains attached to the platform and is held within the cabinet by the design’s mattress retainers, straps, rails, brackets, or other manufacturer-specified components.
Some models allow sheets and a thin comforter to remain on the mattress while it is stored. That is not universal. Thick pillows, bulky toppers, blankets, or bedding may prevent the cabinet from closing or may exceed the available clearance, so follow the instructions for the specific bed.
| State | What the Bed Is Doing | Effect on the Room |
|---|---|---|
| Open | Platform is lowered and supported for sleeping. | The bed occupies its normal sleeping footprint. |
| Closed | Platform and mattress are stored against the wall or inside the enclosure. | More usable floor area becomes available. |
| Hidden | Mattress is concealed behind the cabinet face or panels. | The room can function more like an office, living area, or studio. |
| Styled | Cabinetry, shelves, or decorative panels remain visible. | The stored bed can resemble built-in furniture. |
| Ready | The path is clear, supports are deployed, and the bed is fully lowered. | The sleeping surface can be used like a conventional bed. |
Vertical vs. Horizontal Murphy Beds
A vertical Murphy bed stores with the head of the mattress near the floor and the foot rising toward the ceiling. It generally uses more wall height but less wall width.
A horizontal Murphy bed rotates from one long side. It is wider along the wall but does not need as much vertical height, which can make it useful under lower ceilings or in long, narrow rooms.
Neither orientation is automatically better. Measure the actual cabinet dimensions and the distance the opened bed projects into the room. You also need enough space to walk around the lowered bed, operate doors and drawers, and avoid blocking windows, vents, outlets, switches, or another piece of furniture.
Pro Tip: Measure the bed in both states. Cabinet width and height tell you whether it fits the wall, but the open-bed projection tells you whether the room still works after the mattress is lowered.
Murphy Bed Mechanisms, Mattresses, and Sizes
Murphy-bed mechanisms are designed to counterbalance the moving portion of the bed. Common modern systems include gas-piston lifts and spring-assisted lifts. The correct mechanism is matched to the frame design and expected load, so it should not be modified with unapproved hardware.
Mattress compatibility involves more than length and width. Check at least four requirements:
- Mattress size: The platform must match the intended twin, full, queen, king, or other supported size.
- Mattress thickness: The cabinet needs enough depth to close around the mattress and permitted bedding.
- Mattress weight: The lift mechanism may be balanced for a specified mattress-weight range.
- Construction and storage suitability: The mattress must remain suitable when stored in the orientation required by the manufacturer.
There is no universal 10-inch limit. For example, Murphy Wall-Beds Hardware currently lists a maximum 10-inch mattress core with its regular-height legs and up to 12 inches with extended legs. Other manufacturers publish different requirements.
That is why buying the mattress before checking the wall-bed specifications can cause trouble. A mattress that is too thick may keep the unit from closing, while one that is outside the recommended weight range may change how the lift mechanism behaves.
Many wall beds use a platform or slatted support rather than a conventional box spring. Again, follow the exact product specification rather than assuming every Murphy bed is built the same way.
Murphy Bed Safety and Everyday Use
A properly assembled Murphy bed should open and close in a controlled manner and remain stable when fully deployed. The most important safety requirement for a wall-mounted unit is correct installation into the structural support specified by its manufacturer.
Warning: Do not rely on drywall alone or improvise mounting hardware. Follow the exact instructions for your bed and wall construction. Stop using the bed if the cabinet shifts, mounting hardware loosens, the frame binds, a support leg fails to lock into its intended position, or another structural part appears damaged.
This is a real safety issue. On August 13, 2026, the U.S. Consumer Product Safety Commission announced a recall of certain Merax Murphy beds because the frame could fall during assembly or disassembly. CPSC reported two injuries involving beds that fell during assembly when they were not anchored to the wall.
Manufacturer instructions also differ by orientation and system. For example, Murphy Wall-Beds Hardware specifies attachment to structural members for its wall-bed systems and provides separate installation guidance for vertical and horizontal configurations.
For everyday use:
- Keep people, pets, toys, and furniture out of the bed’s movement path.
- Lower and raise the bed using the designated handles or operating points.
- Make sure legs or supports reach their fully deployed position before putting weight on the bed.
- Use only a mattress that meets the manufacturer’s size, thickness, and weight specifications.
- Inspect mounting points, moving hardware, mattress retainers, and support components as directed by the manufacturer.
- Do not use a unit that moves away from the wall, binds, drops unexpectedly, or has bent, cracked, loose, or missing hardware.
- Check the model and manufacturer against current safety recalls if you bought the bed used or are unsure of its history.
The safest Murphy bed is not simply the one with a strong-looking cabinet; it is the one assembled, anchored, loaded, and operated according to the instructions for that exact model.
How to Choose the Right Murphy Bed
Start with your floor plan. Measure the wall width, ceiling height, baseboard depth, cabinet depth, and the bed’s full projection when open. Then add comfortable walking clearance around the lowered mattress.
Next, choose between vertical and horizontal storage. A vertical bed usually works well when wall width is limited and ceiling height is generous. A horizontal model may suit lower ceilings or a wide wall.
Check the wall construction before purchasing. Wall-mounted systems may require attachment to wood studs, metal framing with manufacturer-approved hardware, masonry, blocking, or another specified structural surface. If you cannot positively identify a safe attachment method, use a qualified installer rather than improvising.
Then compare the mattress requirements. Do not look only at thickness. Confirm the permitted mattress weight, dimensions, construction, and bedding clearance as well.
After the fundamentals, compare useful features such as built-in storage, desks, shelving, lighting, sofas, finishes, and motorized operation where available. Added features can be convenient, but they also increase the number of measurements and moving parts you need to consider.
Finally, look at parts availability, warranty terms, installation support, and the manufacturer’s documentation. Clear installation instructions and accessible replacement hardware can matter more over time than decorative features.
Murphy Bed vs. Cabinet Bed
The terms are sometimes used loosely, but a wall-mounted Murphy bed and a freestanding cabinet bed are not always the same thing.
A traditional wall bed pivots a full mattress and bed platform into a tall wall-side enclosure and usually depends on structural attachment specified by the manufacturer. A cabinet bed typically folds a segmented sleeping surface or mattress into a lower freestanding cabinet.
There are also specialized freestanding wall-bed systems, so the product manual—not the marketing name—should determine whether structural anchoring is required.
Murphy Bed Pros and Cons
A Murphy bed can be an excellent solution, but the trade-offs are easier to understand when you separate the space benefit from the installation requirements.
| Advantages | Potential Drawbacks |
|---|---|
| Returns floor space when the bed is stored | Installation can be more demanding than a normal bed frame |
| Allows one room to serve several purposes | Mattress thickness and weight may be restricted |
| Uses a normal-size sleeping surface on many models | Wall-mounted models need suitable structural support |
| Can integrate storage, desks, shelves, or cabinetry | The open bed still needs substantial clear floor space |
| Available in vertical and horizontal layouts | More moving hardware means installation and maintenance matter |
Frequently Asked Questions
What Are the Downsides of a Murphy Bed?
The main downsides are installation complexity, wall and floor-clearance requirements, mattress restrictions, moving hardware, and potentially higher cost than a basic bed frame. A wall-mounted unit also needs suitable structural support. These trade-offs can be worthwhile when recovering floor space is a priority, but they make careful measuring and installation more important.
Does a Murphy Bed Have to Be Screwed Into a Wall?
Most traditional wall-mounted Murphy beds must be securely attached to structural support according to their installation instructions. That may involve wood studs, approved metal-stud hardware, masonry, blocking, or another specified structure. Freestanding cabinet beds and some specialized freestanding systems are different, so never assume a bed can remain unanchored simply because it is marketed as a Murphy bed.
How Does the Mattress Stay on a Murphy Bed?
The mattress rests on the bed platform and may be retained during storage by straps, brackets, rails, or another system built into the specific model. The support legs stabilize the open bed but are not necessarily the mattress-retention device. Some models also allow limited bedding to stay in place, provided it fits within the cabinet clearance.
What Is Better Than a Murphy Bed?
That depends on the room and how you use it. A sofa bed combines seating and sleeping space without a tall wall cabinet. A daybed works well when you want a permanent single-size sleep surface. A loft bed preserves floor area underneath, while a cabinet bed may avoid the tall enclosure used by a traditional wall bed. A Murphy bed makes the most sense when you want a conventional-size mattress to disappear from the floor when it is not needed.
Conclusion
A Murphy bed can turn a bedroom, office, studio, or guest room into a more flexible space by storing the mattress vertically or horizontally when it is not needed. The important details are the ones behind the cabinet face: mechanism type, open-bed clearance, mattress thickness and weight, structural anchoring, and safe operation. Measure both the stored and open positions, follow the exact installation instructions, and choose a mattress that meets the specifications for your model. Done correctly, a wall bed can provide comfortable everyday sleeping space without permanently giving up the rest of the room.
