If you’ve ever tried to shove a standard bed into a room with a sloped attic ceiling, you already know the frustration. It’s like trying to fit a square peg in a round hole, only the peg is a 200-pound mattress and the hole is your guest room. This is exactly where the horizontal full murphy bed enters the chat. Most people think of Murphy beds as those towering vertical cabinets that look like a monolith from 2001: A Space Odyssey. But the sideways version? That’s the real secret for awkward spaces.
Honestly, people underestimate the horizontal orientation. A full-size mattress is 54 inches wide and 75 inches long. When you flip that vertically, you need nearly 7 feet of ceiling clearance and a massive "arc" of floor space for the bed to swing down. A horizontal full murphy bed flips the script. It attaches to the wall along the long 75-inch side. It stays low. It’s less intimidating. It actually works in a basement.

The Low-Ceiling Lifesaver
Ceiling height is the biggest deal-breaker in home renovations. If you’re working in a finished basement or a loft with 7-foot ceilings, a vertical Murphy bed is a non-starter. You’ll hit the joists or the light fixtures before the cabinet is even upright.
The horizontal full murphy bed only needs about 60 to 65 inches of vertical wall space. That leaves plenty of room for crown molding, HVAC vents, or even a shelf above the unit. It’s basically the "short king" of furniture. It’s stable. It’s grounded. Because the center of gravity is lower, it feels significantly less like it’s going to tip over—though you still absolutely have to bolt it to the studs. Seriously, don't skip the studs.
Think about a kid’s room. A vertical bed is a massive heavy door that a ten-year-old might struggle to reach. A horizontal bed is accessible. It sits lower to the ground. It feels like a daybed when it’s open. This makes it way more functional for multi-use spaces where you don't want a giant wooden tower dominating the vibe.
Mechanics and the "Wall-Hugger" Effect
The physics are different here. Most horizontal units use either a piston lift or a spring system. Companies like Murphy Wall Beds Hardware or Rockler provide the guts for these DIY projects, and the tension requirements for a horizontal swing are lighter than the vertical counterparts.
Why? Leverage.
When you pull a vertical bed down, you’re fighting gravity over a longer distance. With a horizontal full murphy bed, the weight is distributed along a wider axis. It’s easier on the hinges. It’s easier on your back.
What about the mattress?
You can't just throw a 14-inch pillow-top on these. Most horizontal cabinets are shallow. You’re usually looking at a maximum mattress thickness of 10 to 12 inches. If you go thicker, the bed won’t close. If you go too thin, you’re basically sleeping on a camping mat. Brands like Lucid or Zinus make memory foam options that work perfectly because they don't "slump" to the bottom of the cabinet when the bed is stored upright. That’s a real problem with cheap inner-springs—over time, the coils settle toward the floor and you end up with a lumpy mess.
Living With a Side-Flip Bed
Let's talk about the "footprint." When a vertical full bed is down, it sticks out about 80 to 85 inches from the wall. In a narrow room, that means you’ve just blocked the door. You’re trapped.
The horizontal full murphy bed only extends about 58 to 60 inches into the room.

That extra two feet of floor space is the difference between being able to walk around the bed and having to crawl over it like an obstacle course. If your room is long and narrow—the classic "railroad" style—the horizontal layout is the only way to keep the walkway clear.
The Nightstand Problem
Where do you put your phone? Your water? A lamp?
Vertical beds often have "cubbies" built into the cabinet side. Horizontal beds are trickier. Because the bed is wide along the wall, you don't have a "headboard" in the traditional sense. Most people end up using the top of the cabinet as a long shelf. It’s actually kinda nice. You get a 75-inch-long surface for books, plants, and charging stations. It functions like a mantelpiece.
Common Myths and Realities
- "It’s going to fly shut while I’m on it." No. Just no. Unless you are sleeping on a bed designed by a cartoon villain, the weight of the mattress and the frame keeps it firmly on the floor. The pistons are there to help you lift it, not to spring-load it like a trap.
- "I can’t use a real mattress." You can. You just need to check the weight specs. If the mattress is too light, the bed might pop up a few inches. If it’s too heavy, the pistons won’t hold it up. It’s a balance.
- "Assembly is a nightmare." Okay, this one is kinda true. Expect 4 to 6 hours of work. If you’re buying from Wayfair or Amazon, the instructions are basically a test of your marriage.
Real World Use Case: The Home Office
In 2026, the "cloffice" (closet office) or the dual-purpose guest room is standard. If you have a desk in your room, a vertical bed usually means you have to move the desk every time someone stays over.
With a horizontal full murphy bed, you can often place a desk on the opposite wall or even adjacent to the bed without the two pieces of furniture ever touching. The low profile keeps the room feeling "airy." It doesn't swallow the light coming in from the window.
Architects often suggest the horizontal orientation for "ADUs" (Accessory Dwelling Units) or tiny homes. When every square inch is a battleground, the shallow projection of a side-flip bed is a tactical win.
Maintenance You’ll Actually Have to Do
You can't just install it and forget it. Every six months, you should check the mounting brackets. Houses settle. Wood expands. If those bolts loosen even a quarter-inch, the frame will squeak.
Also, check the straps. Most horizontal full murphy beds come with velcro or nylon straps to keep the mattress in place when it’s vertical. If you don't use them, the mattress will bunch at the bottom, and the next time you pull the bed down, it’ll be a folded-over disaster.
Actionable Steps for Choosing Yours
- Measure your "Projection" space: Clear 62 inches from the wall. If you can’t walk past that, you need a smaller bed or a different room.
- Locate your studs: You need at least three solid studs to anchor a full-size horizontal cabinet. If you have metal studs, you’ll need special toggles, but wood is preferred.
- Check the baseboard: Most Murphy beds don't have a notch for baseboards. You’ll either have to cut your baseboard or buy a unit that has a "baseboard notch" pre-cut into the side panels.
- Weight the mattress: Before buying the cabinet, check its "minimum mattress weight." If you buy a high-end, lightweight latex mattress, the bed might be "too bouncy" and difficult to keep down.
- Side-clearance: Remember you need room to stand at the side to pull it down. Don't wedge the cabinet into a corner so tightly that you can't reach the handle.
Investing in a horizontal full murphy bed isn't just about saving space; it's about reclaiming a room that would otherwise be "the bed room" and turning it into a studio, a gym, or an office that happens to have a place for your in-laws to sleep once a year. It’s a pragmatic solution for people who live in homes designed by people who didn't think about where furniture actually goes.
