Murphy bed frames, also called cabinet beds or wall beds, are a great way to save space in a small city apartment. These bed frames feature a wall cabinet that the mattress and its foundation lift and fold up into. The outside of a Murphy bed often features stylish additions such as crown molding or open shelves.
Modern Murphy beds are also much safer than they were 10 to 15 years ago. Many newer models come with safety locks and mattress ties to ensure that the bed stays firmly in place during the night.
Before deciding if a Murphy is right for you, it is important to compare the dimensions of your sleep space with those of a standard wall bed. Throughout this article, we outline the measurements of both vertical and horizontal Murphy beds.
How to Measure for a Murphy Bed
When measuring a room for a Murphy bed, you should consider the height, width, and depth of the bed when it is in the closed position. You should also look at the projection of the bed when it is open. This is the length from the wall to the edge of the bed frame. Knowing these dimensions will give you a better understanding of how the bed will fit in your space.
The dimensions outlined in this article are for fully assembled Murphy beds. Also, these measurements are for wall beds designed to accommodate standard size mattresses, such as twin, twin XL, full/double, queen, and king size mattresses.
Vertical Murphy Bed Dimensions
Vertical Murphy beds are the most common because they resemble a normal bed frame when in the open position. This model allows you to enter the bed from either side. Vertical Murphy beds work best in spaces with ample ceiling height to accommodate the cabinet. When considering height it is also important to account for any ceiling fans. When pulling down the bed, be sure you have enough clearance to avoid fans and chandeliers.
The following chart shows the most common dimensions for a standard vertical Murphy bed.
Once you determine the size you want, be sure you have the ceiling height and floor space for the bed to fit comfortably. You will also want to leave 30 to 36 inches of space on each side of the bed. This open space will allow you to move freely around the bed.
|Twin||82 - 87 inches||43 - 46 inches||18 - 21 inches||80 - 82 inches|
|Twin XL||87 - 89 inches||43 - 46 inches||18 - 21 inches||85 - 87 inches|
|Full/Double||82 - 87 inches||57 - 61 inches||18 - 21 inches||80 - 82 inches|
|Queen||87 - 89 inches||64 - 68 inches||18 - 21 inches||85 - 87 inches|
|King||89 - 92 inches||84 - 86 inches||18 - 21 inches||85 - 87 inches|
Horizontal Murphy Bed Dimensions
Horizontal Murphy beds are less common, but they are a great option for a child’s bedroom, guest room, or in a space with low ceilings. These frames are side-mounted, so you can enter the bed only from one side (the side not attached to the wall).
The chart below outlines the typical dimensions for a standard horizontal Murphy bed.
|Twin||45 - 48 inches||80 - 85 inches||16 - 20 inches||44 - 46 inches|
|Twin XL||45 - 48 inches||85 - 90 inches||16 - 20 inches||44 - 46 inches|
|Full/Double||62 - 64 inches||80 - 85 inches||16 - 20 inches||58 - 60 inches|
|Queen||68 - 70 inches||85 - 90 inches||16 - 20 inches||65 - 68 inches|
|King||68 - 70 inches||85 - 90 inches||16 - 20 inches||78 - 80 inches|
Murphy Bed Side Cabinet
Many Murphy beds also come with side cabinets on one or both sides of the bed. Adding cabinets to your vertical or horizontal wall bed is a great way to add shelving for pictures or books. You can also use these cabinets for additional storage space. When measuring for your new Murphy bed, be sure to account for cabinets if this is a feature you want your new frame to have.
Most Murphy bed cabinets have a height that is about half an inch to an inch below the top of the bed (when in the closed position). This applies to both horizontal and vertical models. The depth of the cabinet is typically the same at the bed.
However, the width of the cabinets can vary between 18 and 30 inches. Therefore, it is important that the wall you plan to place your Murphy bed on be long enough to accommodate the width of the bed and the cabinets.
Vertical Side Cabinet Dimensions
|Twin||79.25 inches||18 inches, 24 inches, 30 inches||16 inches|
|Twin XL||84.75 inches||18 inches, 24 inches, 30 inches||16 inches|
|Full/Double||79.25 inches||18 inches, 24 inches, 30 inches||16 inches|
|Queen||84.75 inches||18 inches, 24 inches, 30 inches||16 inches|
|King||84.75 inches||18 inches, 24 inches, 30 inches||16 inches|
Horizontal Side Cabinet Dimensions
|Twin||43 inches||18 inches, 24 inches, 30 inches||16 inches|
|Twin XL||64 inches||18 inches, 24 inches, 30 inches||16 inches|
|Full/Double||58 inches||18 inches, 24 inches, 30 inches||16 inches|
|Queen||64 inches||18 inches, 24 inches, 30 inches||16 inches|
|King||64 inches||18 inches, 24 inches, 30 inches||16 inches|
How to Choose a Mattress for Your Murphy Bed
Most Murphy beds are designed for mattresses that measure 12 inches thick. Since most mattresses are between 9 and 12 inches thick, it is not difficult to find one that will fit comfortably inside your wall bed.
Most mattress types, including memory foam, latex foam, hybrid, and innerspring mattresses, can be paired with a Murphy bed. However, slumping can be an issue when using a wall bed. Since the mattress has to sit in an upright position for long periods of time, the pressure can cause bunching on either end of the mattress.
Slumping is common with innerspring and hybrid mattresses because the coil springs tend to weigh more, creating more pressure on one end of the mattress. Therefore, most Murphy bed manufacturers recommend using memory foam or latex foam mattresses. Since foam mattresses are more durable, they won’t bunch as much, even if they are vertical for a long time.
Pair Your New Murphy Bed With an Amerisleep Mattress
Whether for a home office or a vacation rental, Murphy beds are a great addition to your home. To create an inviting sleep environment, we recommend pairing your new Murphy bed with one of our advanced memory foam mattresses.
Our AS2 and AS3 models each have a 12-inch depth, while our AS1 has a 10-inch depth. Either of these options will work well with a wall bed, no matter which style you choose. Plus, each Amerisleep mattress comes with a 20-year warranty that covers manufacturing defects, such as sagging or indentations. We also offer a 100-night risk-free sleep trial that allows you to test out the mattress at home and make sure it offers the support you are looking for.
The top layer of each Amerisleep mattress features our unique plant-based memory foam, Bio-Pur®. During manufacturing, we remove a portion of the petroleum-based oils from the foam and replace them with plant-based oils.
This process allows us to create a material that is non-toxic and eco-friendly. Plus, Bio-Pur® won’t trap heat the way most memory foam varieties do—allowing you to sleep cool and comfortable every night.
Every Amerisleep all-foam mattress, except for our firmest model, the AS1, features our Affinity foam with HIVE® technology. This transition layer has hundreds of hexagonal cutouts across the surface of the foam. These cutouts are designed to respond differently to pressure for more adequate contouring.
Near the hip and shoulder joints, cutouts are further apart, allowing them to compress more easily and prevent painful pressure points from forming near these sensitive areas. Along the back and lumbar region, cutouts are closer together to create a firmer, more stable support system.
The base of our memory foam mattresses is made with Bio-Core® foam—a sturdy support foam that helps maintain the structure and integrity of bed. This foam base guards against sagging and indentations, so the mattress can support you correctly for many years.
Best Amerisleep Mattresses for Murphy Beds
The AS1 is our firmest model—perfect for back and stomach sleepers who prefer a mattress with very little give. This bed has a 2-inch Bio-Pur® layer and an 8-inch base of our sturdy support foam, Bio-Core®.
The AS1 has a firm, yet gentle support system. The Bio-Pur® ensures body weight is distributed evenly, so the hips and shoulders experience minimal sinking. This firmness reduces any pressure on the spine, so back sleepers wake up with fewer aches and pains.
The AS2 has a medium-firm feel that works well for back sleepers who prefer a bit more contouring. The AS2 is 1 inch thicker than our AS1 model. It has a 2-inch Bio-Pur® comfort layer, a 3-inch Affinity foam layer with HIVE® technology, and a 7-inch Bio-Core® base.
This mattress is ideal for those with back pain because it is firm enough to support the lumbar spine and prevent excessive sinking of the hips and shoulders. The slight softness of the AS2 also helps protect sensitive areas, like the hip and shoulder joints. With the joints protected and the spine aligned, the muscles in the back can fully relax and recover.
The AS3 is our most popular mattress because it has the most universal comfort level. The medium firmness of this bed works well for most body types and sleep positions, including side sleepers, back sleepers, and combination sleepers.
The 3-inch Bio-Pur® comfort layer cradles the body with pressure-free support, no matter which position you rest in. Beneath the comfort layer is 2-inches of our Affinity foam with HIVE® technology that helps keep the heaviest parts of the body lifted and aligned to alleviate any pressure on the spine. The base of the AS3 features 7-inches of our Bio-Core® foam, which provides further protection against uncomfortable sinking and helps to maintain the shape of the mattress.
