Space is expensive. Whether you’re paying a mortgage in a crowded suburb or rent in a city like New York or San Francisco, every square foot has a literal dollar value attached to it. Yet, most of us have that one room. You know the one. It has a dusty queen mattress that gets used exactly twice a year when the in-laws visit, and for the other 363 days, it’s basically a graveyard for laundry piles and half-finished projects. It's a waste. Honestly, the murphy bed wall bed is the only logical solution to this weird modern problem of having more stuff than floor.
William Lawrence Murphy figured this out over a century ago. Legend has it he was living in a one-room apartment in San Francisco and wanted to entertain an opera singer. Since it wasn't socially acceptable for a lady to enter a man’s bedroom, he engineered a pivot and counterweight system to tuck his bed into the closet. Suddenly, his bedroom was a parlor. He got the girl, and we got a way to make a 600-square-foot apartment feel like a palace.
The Engineering Behind the Fold
You might think a murphy bed wall bed is just a mattress on a hinge. It’s not. If it were that simple, the thing would either crush you or be impossible to lift. Most modern systems rely on one of two mechanisms: piston lifts or spring loops.
Piston systems use gas pressure, similar to the struts that hold up the trunk of your car. They’re incredibly smooth and usually have a "soft-open" feature so the bed doesn't just slam into the floor if you let go. On the flip side, high-quality spring mechanisms are often preferred by high-end installers because they can be adjusted over time. If you buy a heavier mattress three years from now, you can just tighten the tension on the springs to compensate. If a piston fails, you basically just have to replace the whole canister.
There’s a common fear that these things will fold up while you’re sleeping and trap you inside like a cartoon character. It’s a classic trope, but physics says no. The weight of the mattress and the frame, combined with the way the center of gravity shifts once the bed is horizontal, makes it nearly impossible for a bed to spontaneously close. Most units require a deliberate "lift" of about 20-30 pounds of force just to start the closing process.
Why the Mattress Matters (and Why Most People Get It Wrong)
Here is a secret: you don't need a special "Murphy mattress." You can use almost any standard mattress, but there is a massive catch. Depth.
Most wall bed cabinets are designed for a mattress between 9 and 12 inches thick. If you try to shove that ultra-plush, 15-inch pillow-top you bought on sale into a standard cabinet, the bed won't close. Or worse, you’ll force it shut and ruin the internal structure of the mattress. Also, weight is a factor. A solid latex mattress can weigh a ton. If the mattress is too heavy, the lift mechanism—whether it's pistons or springs—won't be able to keep the bed in the "up" position, and it might start to creep away from the wall.
Check the manufacturer's specs. Companies like Murphy Wall Beds Hardware or Wilding Wallbeds are very specific about weight limits. If you go too light (like a cheap foam mattress), the bed might be difficult to keep down. If you go too heavy, it’s a back-breaker to lift. It’s about balance.
Beyond the "Hidden" Look: The Multi-Functional Reality
We’ve moved past the era where a murphy bed wall bed was just a fake wardrobe. Now, they’re libraries, desks, and sofas.
- The Desk-Bed Combo: This is the holy grail for remote workers. A large desk sits on the front of the bed. When you pull the bed down, the desk stays parallel to the floor, meaning you don't even have to move your laptop or your coffee mug. It just tucks underneath the bed.
- The Sofa Murphy: This is perfect for a primary living space. You have a legitimate three-seater sofa during the day. At night, the bed folds down right over the top of the cushions. No moving furniture around.
- The Library Pivot: These are the fancy ones. A set of bookshelves splits in the middle or pivots to the side to reveal the bed. It’s very James Bond, but it’s also remarkably practical for people with huge book collections.
DIY vs. Professional Installation
Can you build one yourself? Yeah. Should you? That depends on how much you trust your ability to find a wall stud.
A murphy bed wall bed exerts a tremendous amount of leverage on the wall. When you pull a queen-sized bed down, you are essentially using a giant lever to try and pull the cabinet away from the drywall. If you don't anchor it into the studs with heavy-duty lag bolts, the whole unit can come crashing down. This isn't like hanging a picture frame. This is structural.
If you’re handy, companies like Rockler sell the hardware kits. You buy the pistons and hinges, and then you go to the lumber yard and buy your own plywood. It’ll save you a few thousand dollars, but it’ll cost you a week of your life in the garage. If you want something that looks like actual furniture and doesn't involve you sweating over a table saw, buying a pre-made unit from a place like BredaBeds or Resource Furniture is the way to go. They send you the precut boards, and it’s basically IKEA on steroids.
The Room-by-Room Breakdown
Think about your home layout. A guest room is the obvious choice. But what about the basement? A basement that’s 800 square feet of "open space" often feels cavernous and cold. Adding a wall bed in a corner turns it into an instant guest suite without sacrificing the play area for the kids.
Or consider the home gym. Nothing kills the vibe of a workout like a giant, stationary bed frame taking up the space where your squat rack should be. By switching to a murphy bed wall bed, you regain that floor space for yoga mats or a stationary bike. When the guests show up, the gym "disappears."
Small Apartment Survival
In a studio apartment, this isn't a luxury; it's a survival tactic. Living in a room where you can always see your unmade bed is mentally draining. It makes it hard to "turn off" the day. Being able to physically put your bed away creates a psychological boundary between "sleep time" and "live time." It’s a ritual. It changes the energy of the room.
The Cost Reality
Let’s talk money. You can find cheap metal-frame murphy beds on Amazon for $500. Avoid them. They’re squeaky, they’re flimsy, and the springs often lose tension within a year. A decent mid-range wood or laminate murphy bed wall bed is going to run you between $1,500 and $3,500. If you start looking at the high-end Italian imports with integrated LED lighting and motorized folding mechanisms, you’re looking at $10,000 and up.
Is it worth it? Compare that cost to the cost of adding an extra room to your house. In most parts of the country, an addition costs $200 to $400 per square foot. Spending $3,000 to reclaim 35 square feet of floor space is actually a bargain.
Critical Considerations Before You Buy
- Ceiling Height: Most vertical murphy beds need at least an 8-foot ceiling. If you have low ceilings or a basement with soffits, you might need a horizontal (side-tilt) model. These fold out sideways and are much lower to the ground.
- The Swing Out: People always forget to measure the "projection." This is how far the bed sticks out into the room when it's open. For a queen bed, you need about 85 to 92 inches of clear space from the wall. If your dresser is in the way, you’re going to be moving furniture every single night.
- The Flooring: If you have thick, shaggy carpet, some models might struggle with the "legs" that flip down to support the foot of the bed. Level ground is your friend here.
- Lighting: Most wall beds create a dark "cave" once you’re tucked inside the cabinet. Look for models with built-in puck lights or make sure you have a bedside table nearby with a lamp.
Common Misconceptions
People think these beds are uncomfortable. That’s a carryover from the days of thin sofa-bed mattresses with a bar in the middle of your back. But a murphy bed wall bed uses a real mattress. There is no bar. There is no folding the mattress in half. It stays flat. If you put a high-end Tempur-Pedic or a Serta on a murphy frame, it feels exactly like a regular bed. The only difference is where it goes when you’re done.

Another myth is that they are hard to open. Most are designed so that a child or an elderly person can operate them. The counterbalancing is so precise that the bed should almost feel weightless once it’s past the 45-degree mark. If you have to struggle to lift it, the tension is set incorrectly.
Actionable Steps for Your Space
If you're tired of tripping over a bed that nobody sleeps in, here is how you actually get this done.
First, measure your wall. Not just the width, but the height. Note where the outlets are located, because you’re probably going to cover one up, and you might want to move it inside the cabinet for charging your phone at night.
Second, decide on the orientation. Vertical is the most natural to sleep in (you don't have to climb over your partner), but horizontal is better for narrow rooms or rooms with low ceilings.
Third, choose your mattress before you buy the bed. Knowing the exact depth and weight of your mattress will prevent you from buying a frame that can't handle the load.
Finally, check your wall type. If you have metal studs (common in high-rise condos), you'll need special toggles. If you have masonry or brick, you'll need a hammer drill and Tapcon screws. Don't guess. Pull the trigger on a high-quality kit, spend a Saturday doing the install, and finally get your room back. You’ve been paying for that square footage for years; it’s time you actually got to use it.
