Quick Answer: A sofa Murphy bed combines a fold-down wall bed with a built-in sofa, using the same space for sitting by day and sleeping at night. Queen Murphy beds are most popular, and most need a foam or latex mattress 8 to 12 inches thick. Ideal for guest rooms, studios, and tight spaces.
Brad, Owner since 1987: "We have been helping Brantford families sleep better since 1987. Every customer gets personal attention, honest advice, and the kind of follow-up service you just do not get from big box stores."
If you have ever wished your guest room could double as a home office, or your studio apartment had more breathing room during the day, a sofa murphy bed might be exactly what you need. These clever wall beds fold up into a cabinet when not in use, giving you back valuable floor space without sacrificing a good night's sleep. Here at Mattress Miracle in Brantford, we have been helping families find the right sleep solutions since 1987, and we have seen first-hand how a well-chosen murphy bed can change the way a small room works.

What Is a Murphy Bed?
A murphy bed (also called a wall bed) is a bed that folds up into a wall-mounted cabinet when you are not using it. The concept has been around for over a century, patented by William Lawrence Murphy in the early 1900s, and the basic idea has stayed the same: give people a real bed that disappears when they need their floor space back.
Modern murphy beds have come a long way from the creaky, spring-loaded contraptions of old movies. Today's models use gas-piston mechanisms that make raising and lowering the bed smooth and almost effortless. Many include built-in shelving, desks, or lighting. And the most popular modern variation, the sofa murphy bed, adds a couch right into the design so the room stays fully functional whether the bed is up or down.
The terms "murphy bed" and "wall bed" are used interchangeably. Both refer to the same fold-up concept. Some retailers also use "panel bed" or "cabinet bed" for freestanding versions that do not mount to the wall, though those are technically a separate category.
What the Research Shows
Sleep quality depends heavily on mattress support, not the bed frame. A 2021 study published in the Journal of Chiropractic Medicine confirmed that mattress firmness and material quality are the primary factors affecting spinal alignment during sleep. This means a murphy bed with a proper mattress can deliver the same quality of rest as a traditional bed frame, as long as the mattress meets your comfort and support needs.
Sofa Murphy Bed Types and Styles
Not all murphy beds are built the same. Understanding the different types will help you pick the right one for your space and lifestyle.
Standard Cabinet Murphy Bed
This is the classic design. The mattress sits on a platform inside a tall cabinet that mounts to the wall. When closed, the cabinet looks like an armoire or bookshelf. When you need the bed, you pull a handle and the platform folds down on gas pistons. These work well in dedicated guest rooms or home offices.
Sofa Murphy Bed Combo
The sofa murphy bed is the most popular choice for living areas. It pairs a wall-mounted bed cabinet with a backless sofa that sits in front of it. When you lower the bed, it folds down over or around the sofa. During the day, you have a comfortable couch. At night, you have a full-size bed with a real mattress. Unlike a traditional sleeper sofa, the murphy bed version uses a standard mattress (not a thin foldable one), so the sleep quality is noticeably better.
Desk Murphy Bed
These combine a fold-down bed with a built-in desk surface. When the bed is folded up, you have a workspace. Some models even let you leave items on the desk while the bed is down, thanks to a rotating mechanism. This is a strong option for anyone working from home in a small space.
Freestanding Cabinet Bed
A cabinet bed does not attach to the wall. Instead, the mattress folds into a compact, furniture-grade cabinet that often doubles as a TV stand or sideboard. These are easier to install (no wall anchoring needed) and are a good fit for renters, though the mattress is usually thinner and the overall sleep surface is smaller than a wall-mounted murphy bed.
Comfort Tip
If you are choosing a sofa murphy bed for regular use (not just occasional guests), prioritize models that accept a queen-size mattress at least 10 inches thick. A thinner mattress might save cabinet depth, but you will notice the difference in support after more than a few nights. Pair it with a quality mattress protector to keep the mattress fresh, especially since it spends part of its life folded upright.
Vertical vs. Horizontal Wall Beds
Murphy beds come in two orientations, and the right choice depends on your room dimensions.
Vertical Murphy Beds
Vertical wall beds are the most common type. The bed folds down from the shorter (head) end, so the headboard is against the wall and the foot of the bed extends into the room. You can get in from either side, just like a traditional bed. A vertical queen murphy bed needs about 65 inches of wall width and 85 to 90 inches of floor clearance when open.
Vertical models are the better choice when you have standard or tall ceilings (8 feet or more) and enough depth in the room for the bed to fold all the way down.
Horizontal Murphy Beds
Horizontal wall beds fold down from the long side. They need more wall width but less vertical cabinet height, making them a smart pick for rooms with low ceilings, sloped walls, or large windows. Twin and full sizes are most common in horizontal configurations, though some queen-size horizontal models are available.
One trade-off with horizontal beds: you typically enter the bed from only one side (the open edge), which can feel less natural for couples.
Quick Comparison
| Feature | Vertical Murphy Bed | Horizontal Murphy Bed |
|---|---|---|
| Best ceiling height | 8 ft or taller | Under 8 ft / sloped |
| Wall width needed (queen) | ~65 inches | ~85 inches |
| Entry | Both sides | One side |
| Most common sizes | Full, Queen, King | Twin, Full |
| Sofa combo available | Yes (very common) | Less common |

Murphy Bed Sizes: Twin to King
Murphy beds are available in all standard mattress sizes. Here is a breakdown to help you match the right size to your room and needs.
Twin Murphy Bed (38" x 75")
Ideal for kids' rooms, student spaces, or a narrow spare room. A twin wall bed takes up very little wall space, especially in horizontal orientation. If you are furnishing a child's room and want to learn more about twin sizing, our twin bed guide covers everything you need to know.
Full / Double Murphy Bed (54" x 75")
A solid middle ground. Full-size murphy beds are wide enough for a single adult to sleep comfortably and can work for couples in a pinch. They need less wall space than a queen, making them a practical choice for tighter rooms.
Queen Murphy Bed (60" x 80")
The queen murphy bed is by far the most popular size, and for good reason. It provides enough room for two people to sleep comfortably, fits standard queen bedding (check our queen bed sheets guide for recommendations), and strikes a good balance between sleep space and room footprint. When folded into its cabinet, a vertical queen murphy bed typically measures about 66 inches wide, 16 to 20 inches deep, and 88 to 92 inches tall.
King Murphy Bed (76" x 80")
King-size wall beds are less common but available from several manufacturers. They need a wide wall (at least 80 inches) and a room with generous floor depth. If you are considering a king but are not sure about sizing, our California king bed guide explains the differences between standard and California king dimensions.
Choosing the Right Mattress for a Murphy Bed
This is where many people make mistakes. Not every mattress works well in a wall bed, and the wrong choice can lead to discomfort, sagging, or trouble with the fold-up mechanism.
Mattress Thickness
Most murphy bed frames accept mattresses between 8 and 12 inches thick. The sweet spot for most models is 10 to 11 inches. Going thicker than your frame allows will prevent the cabinet doors from closing properly. Going too thin, and you may feel the support slats through the mattress.
Always check your specific murphy bed manufacturer's specs before buying a mattress. Some brands cap thickness at 10 inches, while others accommodate up to 13 inches.
Best Mattress Types for Murphy Beds
Memory foam and latex mattresses are the top recommendations for wall beds. They are lightweight, flexible, and hold their shape well even when stored vertically for long periods. A quality foam mattress will not develop the lumps and sags that come from being folded upright day after day.
Innerspring and hybrid mattresses can work in murphy beds, but they carry more risk. The coil springs are heavier, which puts extra strain on the lift mechanism, and the weight distribution can cause the filling to shift or bunch over time when stored vertically. If you prefer the feel of springs, look for a hybrid with a low coil count and a thick foam comfort layer on top.
For a quality foam option that fits most murphy bed frames, our 5" RV/Bunk Foam Mattress is a popular choice for cabinet beds and thinner-profile wall beds. For a thicker, more supportive option, the Gel Comfort Cooling Memory Foam Mattress delivers pressure relief and temperature regulation that works beautifully in a queen murphy bed.
Mattress Weight
Weight matters more than you might think. Your mattress needs to weigh at least 55 pounds to keep the bed stable when lowered (lighter mattresses can cause the bed to drift back up). At the same time, most manufacturers recommend keeping the mattress under 100 to 110 pounds to avoid overworking the gas-piston mechanism. Memory foam mattresses typically fall right in this range.
What We Recommend
For most queen murphy beds, we recommend a 10-inch memory foam or gel-foam mattress. It fits within nearly every manufacturer's thickness requirement, provides solid support and pressure relief, weighs between 60 and 80 pounds (ideal for gas-piston mechanisms), and holds its shape well during vertical storage. If you want added cooling, our Gel Comfort Mattress is Canadian-made and designed for temperature regulation. Pair it with a Bamboo Plus Mattress Protector to guard against dust and moisture while the bed is stored upright.
Pros and Cons of Murphy Beds
A murphy bed is a meaningful investment, so it helps to weigh the advantages and drawbacks honestly before committing.
Advantages
- Significant space savings. A folded queen murphy bed takes up roughly 9 square feet of wall space. An open queen bed takes about 33 square feet of floor space. That is a lot of room you get back during the day.
- Real mattress comfort. Unlike sleeper sofas that use thin, folded mattresses over metal bars, a murphy bed uses a full-size, standard mattress. The sleep quality is comparable to a traditional bed.
- Multi-functional rooms. A sofa murphy bed turns a single room into a living room, guest room, and (with a desk add-on) home office. For condos and smaller homes, this flexibility is hard to beat.
- Clean look. When folded, a quality murphy bed looks like a cabinet or built-in shelving unit. There is no visible bed cluttering the room.
- Long lifespan. Well-built murphy beds with quality hardware can last 15 to 25 years with proper care.
Drawbacks
- Higher upfront cost. A good murphy bed frame runs between $1,300 and $5,000+ in Canada, plus the cost of the mattress. That is more than a basic bed frame, though you are also getting furniture (sofa, cabinet, or desk) rolled in.
- Installation requirements. Most wall beds need to be anchored to wall studs. This means drilling into the wall, which may not be allowed in some rental units. Freestanding cabinet beds are the exception.
- Wall and ceiling requirements. You need a straight, level wall without windows, outlets, or obstructions where the bed will mount. Rooms with sloped ceilings, unusual angles, or limited wall space may not work.
- Daily folding routine. You need to fold the bed up and down each day. Modern gas pistons make this easy (it takes about 10 seconds), but it is still a step that a traditional bed does not require.
- Mattress limitations. You are limited on mattress thickness and weight, which narrows your options. Very thick pillow-top mattresses and heavy innerspring models may not be compatible.
If you are also exploring how to improve the comfort of a thinner murphy bed mattress, adding a quality topper can make a real difference. Our foam bed topper guide walks through the options.
Installation and Room Planning
Before you order a murphy bed, measure your room carefully. Here are the key dimensions to check.
Wall Space
For a vertical queen murphy bed, you need at least 65 inches of uninterrupted wall width and 88 to 92 inches of wall height. The wall must be flat and free of windows, vents, electrical panels, or baseboards that stick out. If you are adding side cabinets or shelving (common with sofa murphy bed units), add 12 to 24 inches per side.
Floor Clearance
When the bed folds down, the foot will extend about 85 to 90 inches into the room for a queen. Make sure there is nothing in that zone: no furniture that cannot be moved, no doors that swing into the path, and enough room to walk around the bed on at least one side.
Ceiling Height
Standard 8-foot ceilings work fine for most vertical murphy beds. If your ceilings are lower than 8 feet, consider a horizontal model or a freestanding cabinet bed instead.
Wall Construction
Murphy beds must be anchored into wall studs, not just drywall. If your wall is concrete or masonry (common in basements), you will need concrete anchors. Make sure to locate your studs before choosing the exact placement.
Assembly
Most murphy beds arrive flat-packed and require 2 to 4 hours of assembly with two people. Some retailers offer professional installation for an additional fee. If you are not comfortable with wall anchoring and heavy lifting, professional installation is worth considering.
For Brantford Residents
Many homes in Brantford were built in the early-to-mid 1900s, and older homes can have plaster walls, non-standard stud spacing, or lower ceilings in upper floors. If you live in one of Brantford's charming older neighbourhoods, it is worth having a contractor check your wall construction before installing a wall bed. For renters in newer apartments and condos along the Grand River area, a freestanding cabinet bed may be the better option since it requires no wall mounting.

441 1/2 West Street, Brantford, Ontario
Call 519-770-0001Can I use a regular mattress in a murphy bed?
Yes, but with some conditions. The mattress must fall within your murphy bed's thickness limit (usually 8 to 12 inches) and weight limit (typically under 110 pounds). Memory foam and latex mattresses work best because they hold their shape during vertical storage. Thick pillow-top innerspring mattresses are generally not recommended because the coils can shift and bunch over time from being stored upright. Always check your specific murphy bed manufacturer's guidelines before purchasing a mattress.
Is a sofa murphy bed comfortable enough for every-night use?
A sofa murphy bed can absolutely be comfortable for nightly use, provided you pair it with a quality mattress. Because murphy beds use standard full-size mattresses (unlike sleeper sofas with thin folding mattresses), the sleep surface is comparable to a traditional bed. The key is choosing a mattress with the right firmness and support for your body. A 10-inch memory foam or gel-foam mattress in a queen murphy bed is a comfortable option for daily sleepers. Adding a mattress topper can further customize the feel.
How much wall space does a queen murphy bed need?
A vertical queen murphy bed typically requires about 65 inches (5.4 feet) of wall width and 88 to 92 inches (7.3 to 7.7 feet) of wall height. When the bed is open, it extends about 85 to 90 inches (7 to 7.5 feet) into the room. If you are adding side cabinets, you will need an additional 12 to 24 inches per side. The wall must be flat, level, and free of windows or obstructions in the mounting area.
Are murphy beds safe? Can they fall on you?
Modern murphy beds are very safe when properly installed. They use counterbalanced gas-piston or spring mechanisms that control the speed of the bed as it lowers, preventing it from dropping suddenly. Most models also include safety locks that keep the bed in the up position until you intentionally release them. The most important safety factor is proper wall anchoring. A murphy bed that is not securely fastened to wall studs can tip forward. Always follow the manufacturer's installation instructions, and consider professional installation if you are unsure about anchoring.
What is the difference between a murphy bed and a cabinet bed?
The main difference is in how they mount. A traditional murphy bed attaches to the wall and folds vertically or horizontally into a wall-mounted cabinet. A cabinet bed is freestanding and does not require wall anchoring. The mattress in a cabinet bed folds in thirds and stores inside a compact piece of furniture that often looks like a dresser or TV console. Cabinet beds are easier to install and better for renters, but they typically use thinner mattresses (around 5 to 6 inches) and are usually limited to full or smaller queen sizes. Murphy beds generally offer better sleep comfort due to thicker mattress compatibility.
How long does a murphy bed last?
A well-built murphy bed with quality gas-piston hardware can last 15 to 25 years with normal use. The gas pistons themselves may need replacement after 10 to 15 years (roughly 10,000 cycles), and most manufacturers sell replacement piston kits. The mattress will need replacing on its own schedule, typically every 7 to 10 years depending on usage and material quality. The cabinet structure itself, if made from solid wood or quality engineered wood, should last the longest.
Do I need to make the bed every time I fold it up?
You do not need to strip the bed, but you should tuck in loose blankets and sheets before folding. Most murphy beds come with elastic straps or retention bands that hold the mattress, pillows, and bedding in place while the bed is in the upright position. Fitted sheets and light blankets stay put easily. Heavier duvets or thick comforters may need to be removed before folding, or secured with the built-in straps, depending on your model's clearance.
Where can I buy a Murphy bed in Vancouver, British Columbia?
Murphy beds (wall beds) are available in Vancouver through specialty furniture and space-saving retailers. Expand Furniture and Resource Furniture offer Murphy bed systems in the Vancouver area. Local custom cabinet makers can also build them to order. Standard Murphy bed systems include wall-mount hardware and require a mattress typically no thicker than 12 inches and firm enough to stay in place when folded upright. Common sizes are twin, full, and queen. Mattress Miracle is in Brantford, Ontario, but we are happy to advise on the right mattress type and thickness for a Murphy bed by phone.
Where can I buy or have a Murphy bed installed in Montreal?
Murphy beds in Montreal are available through specialty furniture retailers including Clei (Italian folding furniture), Expand Furniture, and local custom cabinet makers. IKEA does not sell a formal Murphy bed system in Canada, though their KALLAX and PAX systems are sometimes adapted for similar purposes. For custom Murphy bed installations in Montreal, searching for local menuisiers (cabinetmakers) who specialize in wall beds is the most reliable approach for a built-in look. Lead times for custom Murphy beds in Montreal typically range from 4 to 10 weeks depending on design complexity.
Can I build a Murphy bed from plans in Canada?
Yes. Murphy bed hardware kits with instructions are available in Canada from manufacturers like Murphy Bed Depot, Rockler (US with Canadian shipping), and specialty hardware suppliers. These kits include the spring mechanism and mounting hardware while you supply the cabinet lumber. Building a Murphy bed from plans requires basic woodworking skills and precise installation - the wall mounting must anchor to studs, and the mechanism must be calibrated for the mattress weight. A twin or full Murphy bed is a practical DIY project; queen Murphy beds require more precise execution. Material costs for a DIY Murphy bed in Canada typically run $500 to $1,200 depending on wood choice.
