Key takeaways
- 3/4″ hardwood plywood (birch, maple, oak veneer): the standard. Holds screws well, stable, takes paint or stain.
- MDF: paints beautifully but is heavy and weak at screw points; fine for face panels, poor for structural sides that carry pivot hardware.
- Solid wood: attractive but moves with humidity; only for face frames and trim, not wide structural panels.
- Melamine-faced particleboard: cheap and pre-finished, but screws for the mechanism need extra blocking.
A frame-only queen Murphy bed is a hardware kit (the lift mechanism, pivot brackets and usually a bed frame or face panel) sold without the surrounding cabinet, so you build or buy the cabinet yourself. It typically saves a large share of the cost of a finished wall bed and lets you match your own cabinetry, but it shifts the hard parts to you: accurate cabinet dimensions, wall anchoring and tuning the mechanism to your mattress weight. Here is what the kits include, the numbers you need and who should go this route.

What “frame only” can mean
Listings use the phrase loosely. Before buying, confirm which of these you are getting:
| Kit type | What’s included | What you supply | Typical price range |
|---|---|---|---|
| Hardware-only kit | Spring or piston mechanism, pivot brackets, hardware, plans | Entire cabinet, bed box, face panel, legs | Usually $250-$700 |
| Hardware plus metal bed frame | Mechanism plus steel mattress frame or deck | Cabinet and face panel | Usually $500-$1,200 |
| Panel-bed kit (no full cabinet) | Mechanism, frame, face panel; mounts to wall with side panels only | Side panels, finish, optional shelving | Usually $1,000-$2,000 |
| Complete cabinet bed | Everything, ready to assemble | Mattress | Usually $1,800-$5,000+ |
Woodworking suppliers such as Rockler and specialist makers such as Create-A-Bed sell kits in this space, and wall-bed brands often sell their mechanisms separately. Specs vary by kit, so the plans included with your hardware always override the general numbers below.
Spring vs piston mechanisms
| Factor | Spring mechanism | Gas piston mechanism |
|---|---|---|
| Adjustability | Tension set by adding or removing springs | Fixed force per piston; swap pistons to change |
| Feel | Smooth, counterbalanced throughout the arc | Smooth; can feel stiff in cold rooms |
| Lifespan | Springs are long-lived; rarely replaced | Pistons commonly need replacement after several years |
| Mattress changes | Re-tune by changing springs | May need different pistons |
| Kit cost | Higher | Lower |
| DIY tuning | Moderate effort | Simple if piston rating matches |
For a bed used nightly, spring systems are generally the more durable choice. Piston kits suit guest rooms where the bed comes down a few times a month and budget matters.
The dimensions that matter for a queen
A standard queen mattress is 60 x 80 inches. The kit is designed around that, but the cabinet you build must account for the bed box, mattress thickness and clearance. These are typical ranges for a vertical (headboard against the wall, bed folds up lengthwise) queen:
| Measurement | Typical range | Planning note |
|---|---|---|
| Cabinet outside width | About 65″-67″ | Add side shelving towers separately if wanted |
| Cabinet outside height | About 84″-88″ | Needs 8 ft ceiling; check crown molding and smoke detectors |
| Closed depth from wall | About 15″-18″ | Plus baseboard gap behind |
| Open projection from wall | About 84″-88″ | Measure to dresser, door swing and radiators |
| Mattress thickness supported | Often 8″-12″ by kit | Thicker mattresses may not close or may bind |
| Mattress weight | Varies; kits are tuned to a weight range | Weigh the mattress before ordering springs or pistons |
| Clear floor when open | About 7.5-8 ft from wall | Leave 24″ or more at the foot for walking |
Horizontal (side-tilt) queen kits are less common; they need a wider wall (about 85-88 inches) but less ceiling height, which can help in rooms with low ceilings or windows above.
Building the cabinet: materials and realities
Material choices
- 3/4″ hardwood plywood (birch, maple, oak veneer): the standard. Holds screws well, stable, takes paint or stain.
- MDF: paints beautifully but is heavy and weak at screw points; fine for face panels, poor for structural sides that carry pivot hardware.
- Solid wood: attractive but moves with humidity; only for face frames and trim, not wide structural panels.
- Melamine-faced particleboard: cheap and pre-finished, but screws for the mechanism need extra blocking.
Sheet count and weight
A plain queen cabinet with bed box and face panel generally uses about five to seven sheets of 4 x 8 ft, 3/4″ plywood. At roughly 60-70 lb per sheet, the finished bed box and cabinet together can easily exceed 250 lb before the mattress. Build the bed box in the room where it will live; a fully assembled queen cabinet often will not pass through a standard 32-inch door or turn in a hallway.
Tools you will realistically need
- Table saw or track saw for straight, square sheet cuts
- Drill/driver, impact driver and a stud finder
- Squares, clamps and a 6-foot level
- Router (optional) for edge profiles
- A second person for lifting the bed box onto the pivots
Expect a weekend or two for an experienced DIYer and longer for a first build, plus finishing time.
Anchoring: the non-negotiable step
A Murphy bed creates enormous leverage at the pivot when the bed swings down. Kits specify anchoring to wall studs and, in many designs, to the floor. Follow the kit’s fastener schedule exactly:
- Fasten the cabinet into at least two studs, usually with lag screws or structural screws through a cleat.
- Drywall anchors alone are not acceptable.
- On masonry or concrete walls, use concrete anchors rated for the load.
- Do not mount over thick carpet pad without solid blocking; the cabinet can rock.
- Renters should get landlord approval; anchoring leaves noticeable holes.
Is a frame-only kit right for you?
| Your situation | Recommendation |
|---|---|
| Comfortable cutting sheet goods square within 1/16″ | Hardware kit is a strong value |
| Want built-in cabinetry that matches existing millwork | Frame-only kit plus custom cabinet |
| No table saw or track saw, no workshop space | Panel-bed kit or complete cabinet bed |
| Bed used nightly by two adults | Spring mechanism, heavier-gauge hardware |
| Guest room, occasional use, tight budget | Piston kit is fine |
| Renter planning to move within two years | Freestanding cabinet bed or a different guest solution |
| Low ceiling (under 7.5 ft) | Horizontal queen kit, if wall width allows |
Common mistakes to avoid
- Buying the mattress last. Mechanisms are balanced to a mattress weight and thickness. Pick the mattress first and give its weight to the kit seller.
- Ignoring baseboards. Many plans assume a flat wall. Remove the baseboard or notch the cabinet so it sits tight to the wall.
- Skipping a retaining strap. Bedding straps keep sheets and pillows in place when the bed is up.
- Underbuilding the bed box. The face panel and bed box take the most stress at the corners; glue and screw every joint.
- Not checking the swing path. Lights, ceiling fans and outlets near the top of the cabinet can block the bed or be hit by it.
Done carefully, a frame-only queen Murphy bed delivers a built-in look and a mechanism as good as many finished units, at a fraction of the cost. The savings come from your time, tools and care with measurements, so be honest about all three before ordering a kit.
