A pre-built murphy bed from a quality manufacturer costs between $1,500 and $4,000 installed—but the same functional result can be achieved with a $300–$600 DIY build using widely available hardware kits. That’s a potential savings of $1,000–$3,000, which explains why murphy bed hardware kit sales have grown 340% since 2020 as urban apartment dwellers and home office workers seek dual-purpose rooms. The question isn’t whether DIY is cheaper—it clearly is—but whether the build complexity matches your skill level and whether the savings justify the 15–30 hours of construction time.
Why Murphy Beds Are Having a Moment
The murphy bed—invented by William Lawrence Murphy in the early 1900s—has evolved from a cramped-apartment necessity into a legitimate design solution for modern living. Average apartment sizes in major US cities have decreased 5–8% over the past decade while remote work has made home offices essential. A murphy bed converts a bedroom into a functional office, gym, or living space during waking hours, effectively giving you an extra room without moving to a larger (and more expensive) home. For a 150-square-foot bedroom at urban rent rates of $3–$5 per square foot monthly, reclaiming that daytime space creates $450–$750 in functional value every month—a return that makes even the most expensive murphy bed a rational investment.
Modern mechanisms have also eliminated the biggest historical complaint: difficulty of operation. Today’s piston-assisted and spring-balanced systems allow a single person to raise and lower a queen-size murphy bed with under 10 lbs of force, compared to the 40–60 lbs required by older spring-only designs. This technological improvement makes murphy beds practical for daily use rather than occasional guest accommodation, which is the paradigm shift driving current demand.
DIY Murphy Bed: Complete Cost Breakdown
Hardware Kit Costs
The mechanism kit is the non-negotiable investment—this is the spring or piston system that makes the bed fold safely. Quality kits range from $150–$350 for a queen mechanism. Create-A-Bed ($150–$200) offers the most affordable piston-lift system with a solid safety record. Rockler Murphy Bed Hardware ($250–$350) provides a premium piston mechanism with a deluxe mounting system that simplifies installation. Lori Wall Beds ($350–$500) includes a complete kit with pre-cut leg framework, reducing custom woodworking to a minimum. Never use non-branded mechanisms from marketplace sellers—the consequences of mechanism failure with a 100+ lb panel above a sleeping person are serious.
Materials and Lumber
The cabinet and bed platform require 2–3 sheets of ¾” plywood ($40–$70 each), 1×4 and 1×6 trim boards ($30–$60), wood screws and hardware ($20–$30), wood glue and finishing supplies ($30–$50), and a mattress support platform ($0 if building from plywood, $60–$100 for a pre-made slatted base). See our best bed sheets. Total materials run $150–$350 depending on plywood grade and finish quality. Using cabinet-grade birch plywood creates a furniture-quality result, while construction-grade plywood with edge banding provides a functional build at half the cost.
Tool Requirements
Minimum tools needed: circular saw or table saw, power drill/driver, level, measuring tape, clamps, and sandpaper or orbital sander. If you don’t own these, tool rental runs $50–$80 for a weekend. A pocket-hole jig ($40) dramatically simplifies frame assembly and creates stronger joints. The total DIY cost for a queen murphy bed using mid-grade materials: $400–$700, or roughly 25–35% of the cheapest pre-built alternative.
Pre-Built Murphy Bed Options: What You’re Paying For
Pre-built murphy beds justify their $1,500–$4,000 price through three primary advantages: professional-grade finish quality, integrated storage solutions (shelving, desk surfaces, side cabinets), and warranty-backed safety assurance. For buyers prioritizing aesthetics in a visible living space, the finish quality difference between DIY and manufactured furniture is significant unless you have advanced woodworking skills.
The best value in pre-built murphy beds comes from flat-pack options that ship disassembled with professional hardware. Bestar Pur Full Murphy Bed ($1,600–$2,200) offers Canadian-built quality with clean modern aesthetics and straightforward assembly. Night & Day Furniture Sagebrush ($1,400–$1,800) provides a solid-wood option in a traditional style. IKEA’s PLATSA system with a murphy bed mechanism ($800–$1,200) represents the budget pre-built option, though quality trails dedicated murphy bed manufacturers.

Build vs Buy: The Honest Decision Matrix
Build DIY If:
You have intermediate woodworking experience (you’ve built furniture before), own or can borrow basic power tools, your room has non-standard dimensions requiring custom sizing, budget is the primary constraint, you enjoy the building process and have 15–25 hours available, or you want maximum customization for built-in shelving and features. The DIY route also makes particular sense for murphy beds in specific configurations like side-fold (horizontal) designs that are harder to find pre-built in affordable options.
Buy Pre-Built If:
You lack woodworking experience or tools, the murphy bed will be in a high-visibility room where finish quality matters, you need integrated storage solutions (desk, cabinets, lighting) that complicate DIY significantly, your time is worth more than the $600–$2,000 savings, or you want a manufacturer warranty on the mechanism (typically 10–25 years for quality brands). A pre-built murphy bed also makes more sense in rental properties where landlord approval may require professional-grade installation documentation.
The DIY Build Process: Step-by-Step Overview
Phase 1: Planning and Measurement (2–3 hours). Measure your wall space, ensuring at minimum 6 inches of clearance on each side and adequate ceiling height (93+ inches for a queen vertical fold). Verify wall stud locations—murphy beds must anchor into studs, not drywall alone. Select your mechanism kit and verify its dimension requirements against your space.
Phase 2: Cabinet Frame Construction (5–8 hours). Build the wall-mounted cabinet that houses the folded bed. This is essentially a large plywood box reinforced with internal supports. Precision matters here—the cabinet must be perfectly square and level for the mechanism to operate smoothly. A ¼-inch deviation can cause binding that makes the bed difficult to raise and lower.
Phase 3: Mechanism Installation (3–4 hours). Mount the spring or piston mechanism according to the kit’s exact specifications. This is the most critical phase—incorrect installation compromises safety. Follow the manufacturer’s torque specifications for all bolts and verify mechanism tension before attaching the bed platform. Most quality kits include detailed instructions and installation videos.
Phase 4: Bed Platform and Finishing (4–6 hours). Attach the bed platform to the mechanism, add the appropriately sized mattress support surface, install retention straps (preventing the mattress from sliding when stored vertically), and apply finish to visible surfaces. Test the complete system 20+ times before first use, listening for unusual sounds or feeling for resistance that indicates alignment issues.
What Most People Get Wrong About Murphy Bed Mattresses
The counterintuitive truth about murphy bed mattresses: thinner isn’t always better, and you don’t necessarily need a “murphy bed specific” mattress. The critical constraint is weight, not thickness. Most mechanisms safely support mattresses up to 60–80 lbs (check your kit’s specifications). A high-quality 8-inch memory foam mattress weighing 55 lbs works perfectly and provides dramatically better sleep quality than the 6-inch “murphy bed mattresses” that many retailers push. The key is avoiding innerspring mattresses—coil systems don’t compress well when stored vertically and can shift internally over time. Memory foam and latex maintain their structure regardless of orientation, making them ideal for daily vertical storage.
A quality mattress for a guest murphy bed can be simpler since it sees occasional use, but a primary-bedroom murphy bed deserves the same mattress quality you’d choose for any nightly sleeper. Don’t let the bed frame type downgrade your mattress investment—you spend the same 7–8 hours sleeping on it regardless of whether it folds into a wall during the day.
Safety Considerations: Non-Negotiable Requirements
Murphy bed safety is not optional engineering. The bed platform (including mattress) typically weighs 80–120 lbs and is suspended vertically during storage. Critical safety requirements include wall-stud mounting with appropriate lag bolts (never drywall anchors alone), a piston or spring mechanism rated for at least 1.5× your mattress weight, mattress retention straps preventing the mattress from sliding out during folding, a locking mechanism that secures the bed in both open (down) and closed (up) positions, and child-safety locks if children are present in the home. The mechanism is the safety-critical component—cheap no-name mechanisms from overseas sellers are the primary cause of murphy bed injuries. Spend the extra $50–$100 on a branded mechanism from Create-A-Bed, Rockler, or comparable manufacturers with documented safety testing.
Murphy Bed Alternatives Worth Considering
Before committing to a murphy bed, consider whether these alternatives better solve your space problem. A high-profile adjustable bed frame with under-bed storage provides significant storage without wall modification. A lofted bed elevates the mattress to create desk or storage space underneath—no mechanism required. A daybed with a quality mattress serves as both sofa and bed without any folding mechanism. A split king setup in a shared space allows one half to fold (using a simpler ottoman-style mechanism) while the other remains as a seating area. Each alternative trades different constraints against different benefits—the murphy bed’s unique advantage is completely clearing floor space, which no alternative fully replicates.
Verdict: Build or Buy Your Murphy Bed
For handy homeowners willing to invest 20+ hours and $400–$700, a DIY murphy bed using the Rockler hardware kit delivers professional-level function at one-third the cost of pre-built options. For everyone else, the Bestar Pur Full Murphy Bed at $1,800–$2,200 provides the best combination of quality, aesthetics, and ease of assembly in the pre-built category. Regardless of which path you choose, invest in a proper mattress rather than settling for the thin, uncomfortable options marketed specifically for murphy beds—your sleep quality depends on the mattress, not the frame that holds it. The murphy bed is a space solution; the mattress is the sleep solution, and both deserve proper attention.
Frequently Asked Questions
Can I install a murphy bed in a rental apartment?
Most murphy beds require wall-stud mounting with lag bolts, which creates holes that exceed normal wear-and-tear provisions in standard leases. However, several solutions exist. Lori Wall Beds offers a freestanding design that leans against the wall with anti-tip anchors (two small holes total). Some pre-built cabinet-style murphy beds are designed as freestanding furniture requiring only tip-prevention wall attachment. Always get written landlord approval and document the installation method—some landlords consider murphy beds an improvement that adds property value.
How long does a murphy bed mechanism last?
Quality piston mechanisms from brands like Create-A-Bed and Rockler are rated for 10,000+ cycles, which translates to approximately 27 years of daily use. See our how long does a mattress last. Spring-based mechanisms may need spring replacement every 5–8 years as springs fatigue and the bed becomes harder to lift. Gas piston mechanisms (similar to car hatchback struts) maintain consistent force longer but cost more to replace when they eventually fail. Budget $100–$200 for mechanism maintenance over a 15-year ownership period regardless of type.
What’s the maximum mattress thickness for a murphy bed?
Most murphy bed mechanisms accommodate mattresses up to 12 inches thick, with the cabinet depth sized accordingly. Standard designs are built for 8–10 inch mattresses, which provide adequate comfort for most sleepers. Going beyond 10 inches adds significant weight (each additional inch adds approximately 8–12 lbs for a queen memory foam) and requires a deeper cabinet that projects further from the wall. For primary bedroom use, an 8-inch high-density memory foam mattress at 4+ lb/ft³ density provides sleep quality comparable to thicker options while staying well within mechanism weight limits.
Can a murphy bed support two adults?
Yes, quality mechanisms support 500–700 lbs of static weight in the down (bed) position, safely accommodating two adults plus mattress weight. The weight concern applies to the up (stored) position and the transition—the mechanism must lift the combined mattress and retention strap weight, not the occupant weight. Never attempt to fold the bed up with anyone on the mattress. When comparing mechanisms, check both the static weight capacity (sleeping load) and the dynamic weight capacity (the weight the mechanism lifts), ensuring the dynamic rating exceeds your mattress weight by at least 50%.
Is a murphy bed more cost-effective than a sofa bed?
For sleep quality, absolutely yes. Murphy beds use standard mattresses that match conventional bed comfort, while sofa beds typically use thin, low-quality mattresses compromised by the folding mechanism beneath. For cost, it depends: a quality sofa bed costs $800–$2,000, and a murphy bed costs $400–$4,000 depending on DIY vs. pre-built. The murphy bed provides superior sleep quality and completely clears floor space, while the sofa bed offers daytime seating without any wall modification. If the room is primarily a bedroom that occasionally hosts guests, a murphy bed wins. If it’s primarily a living room with rare overnight guests, a sofa bed may be more practical.
Do I need a special foundation or box spring with a murphy bed?
No—murphy beds include their own support platform (either a solid panel or slatted base) that replaces traditional foundations entirely. Adding a box spring is impossible since the bed must fold flat against the wall. This is actually an advantage: you save $100–$300 on foundation costs compared to a traditional bed setup. The built-in platform provides adequate support for foam and latex mattresses. If you prefer the feel of a slatted base over a solid platform, several DIY kits offer slatted options, or you can modify a solid platform by cutting ventilation slots.
