The right Murphy bed hardware kit includes engineered mechanisms, detailed instructions, and proper weight ratings for your mattress size and room layout. Choosing the correct hardware system, bed size, and orientation before you begin ensures a safe, smooth-operating bed that functions reliably for years. This guide walks you through comparing gas piston vs. spring systems, selecting the ideal dimensions, and matching your kit to your space.
Why Does the Hardware System Matter Most?
A Murphy bed is only as good as the mechanism behind it. While the cabinet and bed frame are built from wood, the lifting system controls how smoothly and safely your bed operates every day.
A quality Murphy bed kit should include:
- Engineered lifting hardware (gas pistons or springs) tested for regular use
- Clear weight capacity and mattress-compatibility ratings
- Detailed cutting guides with accurate measurements
- Step-by-step construction instructions and assembly diagrams
- Customer support and installation guidance
A lower-priced kit may skip guides, support, or use lighter-duty hardware, a false economy that often leads to alignment problems, difficult operation, and safety concerns down the road.

High-Quality Metal Parts: The Core of Your Murphy Bed
The hardware system is the most important part of any Murphy bed kit because it controls safety, movement, and long-term durability. While the cabinet provides structure, the metal components handle all lifting and motion.
A complete Murphy bed hardware system typically includes:
- Lift mechanism (gas piston or spring system)
This controls the opening and closing movement of the bed and ensures smooth, balanced operation. - Pivot and support brackets
These connect the bed frame to the cabinet and allow controlled rotation during operation. - Mounting hardware
Heavy-duty fasteners and plates are used to securely anchor the system to the wall structure. - Bed frame support components
Structural metal parts that help distribute weight evenly across the frame. - Mattress retention hardware
Straps or locking systems that keep the mattress securely in place when the bed is folded.
Each component works together to ensure smooth operation, stability, and safe daily use. Choosing a well-engineered hardware kit is essential for long-term performance and reliability.
Gas Piston vs. Spring: Which Lifting System Is Right for You?
Most modern Murphy bed kits use either a gas piston system or a spring-based lifting system. Both options are engineered to support regular use, but they differ in how they feel during operation, how they adjust, and the level of maintenance they may require.
Below is a simple comparison to help you understand the differences:
| Feature | Gas Piston System | Spring System |
|---|---|---|
| Operation | Smooth, controlled lift with consistent resistance | More mechanical lift that can feel slightly variable during use |
| Noise | Quiet and stable operation | May produce minor noise depending on alignment and usage |
| No Adjustment Needed | Requires the correct piston set for the bed size, orientation, and mattress weight range | May require more frequent adjustment over time |
| Maintenance | Low maintenance with minimal upkeep | May need periodic tension adjustments |
| User Experience | Modern, smooth, and beginner-friendly | Traditional and functional with a more mechanical feel |
Which System Should You Choose?
For most DIY builders, gas piston systems are preferred because they provide smooth, controlled lifting when the correct piston set is matched to the bed size, orientation, and mattress weight range. This makes kit selection especially important before starting the project.
Which Size Murphy Bed Is Right for Your Room?
Mattress size plays an important role in comfort and space planning. Common Murphy bed mattress sizes include Twin, Full, Queen, and King.
- Twin (39″ × 75″) – Ideal for kids’ rooms, guest spaces, or compact home offices where floor space is limited and flexibility is important.
- Full (54″ × 75″) – A practical choice for single adults or small apartments, offering more sleeping space while still maintaining a compact footprint.
- Queen (60″ × 80″) – The most popular option for couples and multi-use rooms, offering a strong balance between comfort and space efficiency.
- King (76″ × 80″) – Best suited for larger rooms where maximum sleeping comfort is a priority and wall space is available for installation.
Final Murphy bed cabinet and frame dimensions vary by kit design and should always be checked on the product or finished dimensions page before planning installation.
Vertical vs. Horizontal: Choosing the Right Orientation for Your Space
The orientation determines whether the bed folds toward the ceiling or sideways. This is one of the most important decisions and depends on your room dimensions.
Vertical Murphy Beds
Folds up toward the ceiling.
- Best for: Rooms with sufficient ceiling height (8 feet or taller recommended)
- Space efficiency: Minimal floor footprint in open position
- Popular sizes: Queen, King, California King Murphy bed dimensions
Horizontal Murphy Beds
Folds sideways (parallel to the wall).
- Best for: Lower ceilings (7 feet or less), basements with bulkheads or HVAC ducts
- Space efficiency: Requires horizontal wall space
- Popular sizes: Twin, Full, Queen

Before You Order: The Essential Measurement Checklist
Accurate measurements prevent costly mistakes. Take time now to measure carefully.
Ceiling Height
Especially critical for vertical Murphy beds. Measure from the floor to the lowest point (consider light fixtures, HVAC returns, ceiling fans). For vertical beds, allow at least 12 inches of clearance above the cabinet when fully closed.
Wall Width
Measure the unobstructed wall width. Vertical Queen cabinets typically can measure up to 67″ wide; horizontal beds require sufficient wall length for the bed to fold parallel to the wall.
Floor Clearance
Verify the bed can fully open without hitting furniture, windows, or other room elements. Account for mattress thickness (typically 8–12 inches).
Obstacles to Mark
- Electrical outlets and switches
- Air vents, HVAC returns, and ductwork
- Light fixtures and ceiling fans
- Baseboards and trim
- Bulkheads, soffits, or angled ceilings
- Wall thickness and stud locations

Frequently Asked Questions
What exactly is included in a Murphy bed hardware kit?
Most kits include the lifting mechanism (gas pistons or springs), pivot hardware, mounting brackets, adjustment hardware, installation instructions, and detailed diagrams. Many suppliers also provide cutting guides, construction manuals, instructional videos, and customer support.
Are gas piston Murphy beds better than spring systems?
Both systems can work reliably when properly engineered and installed. Gas piston systems are often preferred for smooth, controlled operation and low-maintenance daily use, but the pistons must be matched correctly to the bed size, orientation, and mattress weight range. Spring systems can also be reliable, but they may require more tension adjustment over time.
Can I use a regular mattress in my Murphy bed?
Murphy bed hardware systems are engineered to support specific mattress weight ranges depending on the kit size and configuration. It is important to always match your mattress with the manufacturer’s recommended specifications to ensure safe, smooth, and long-term operation.
How hard is it to build a Murphy bed from a kit?
Most DIY builders with basic tools and woodworking confidence can successfully assemble a bed in 2–4 days by following detailed instructions. The hardest part is usually the initial cabinet assembly and achieving level/plumb during installation. Quality kits reduce this difficulty with cutting guides and assembly diagrams.
Should I choose vertical or horizontal orientation?
Vertical works best if you have a ceiling height of 8 feet or more. Horizontal is ideal for lower ceilings (7 feet or less) or rooms with bulkheads. Measure your space first and choose orientation based on your actual dimensions.
Does a Murphy bed need to be attached to the floor or wall?
Most Murphy beds must be securely anchored to studs in the wall. Some systems may require floor anchoring as well, depending on the design and mattress weight. Always follow manufacturer guidelines for wall type (drywall, plaster, concrete) and anchor specifications.
Can renters install a Murphy bed?
Most Murphy beds require permanent wall anchoring, which renters cannot do without the landlord’s permission. Some freestanding or removable systems exist, but they generally provide less stability and may not support heavier mattresses.
