  • ike many homeowners, I converted a small bedroom into a home office. Its atrade-off that makes sense, except when we have visitors and must give upour bed. We considered buying a sofa bed, but weve never liked sleeping on

    them, and our current sofas dont need replacing.In my search for a new and better alternative I found a solution that isnt new at

    all a murphy bed. Its an ingenious piece of furniture that combines the comfortof a standard mattress with the appearance of a closet or cabinet that is less than 18in. deep. You can customize most designs to fit your homes dcor, adding trim,matching bookcases or even built-in lighting (see Design Options, p. 35).The beds name is attributed to William L. Murphy, who designed and patent-

    ed the original Murphy Bed in San Francisco around 1900. His company, TheMurphy Bed Co., and several others continue to manufacture and sell murphy

    LNow you see it; now you dont. Lift-mechanism hardware makes openingand closing this modern murphy bedeasy for anyone.

  • beds today (see SOURCES ONLINE).Several of these companies havedesigned their own lift systems, someadopting the murphy bed name andothers simply calling their productswall beds.Even though theyve been around for

    more than a century, murphy beds arentcommon in todays homes. You wontfind them in most furniture showrooms,and many people incorrectly assume thatinstallation requires cutting into a wall.Although early versions were built intoapartment walls and concealed withcloset doors, today most murphy beds areplaced in the room like a large piece offurniture. Besides greater installationflexibility, modern murphy beds alsohave improved lift mechanisms, so youdont have to worry about being gobbledup into the wall like the comedians in oldslapstick movies.There are three basic requirements

    to consider before buying or buildinga murphy bed. First, you need at least4 ft. of open wall space for a twin bedand more for a larger bed or if youintend to connect a bookcase. Second,you need 7 ft. of clearable space (witheasy-to-move furniture) in front of thebed for it to open. Finally, you musthave an egress window (a window largeenough for a person to climb through)in any room that will be used for sleep-ing. Check with your local buildinginspections department for minimumegress requirements.

    Murphy bed constructionWhether you choose to call them murphybeds or wall beds, they feature three keycomponents: the lift mechanism, the bedframe and the cabinet. There are twomain types of lift mechanisms: springand piston. Both systems operate under asimilar principle they create force that

    helps lift the bed into the closed position(see How a Murphy Bed Works, p. 37).The force is balanced so that the

    weight of the bed frame and mattresstogether is enough to hold the bed downon the floor. Some spring systems fea-ture adjustable tension, but piston sys-tems are typically not adjustable.Different piston strengths are matched tothe style and size of bed you are build-ing. The variable is the mattress weight.If the mattress that you are using with anonadjustable piston or spring system istoo light, the bed will rise slightly orfloat off the floor. In this case, you mustadd a small amount of weight under themattress to keep it grounded.The bed frame holds the mattress.

    Because the bed frame must fit intothe cabinet, thickness is an issue. Atypical installation does not contain abox spring, and the mattress cannot bemore than 12 in. thick.

    Assemble the inner bed framewith frame struts (inset) made with solid wood 1x2s.Plywood bed rails and panels will conceal this frame.

    Fasten the lift-mechanism hardware to the side rails andvertical side panels and then remove the hardware beforeapplying finish to the pieces.

  • Design optionsMurphy beds can be designed to complement any homes dcor, andyou can install a mattress as large as queen size in either the verticalor horizontal position. The strength of the lift mechanism requireddepends on the configuration that you choose. DC

    Spring systems often incorporate ametal bed frame. These systems areusually fastened to the floor, and thecabinet is a freestanding box builtaround the bed frame. Piston systemsuse a wood bed frame that is connectedto the cabinet by pivots, and the cabinetis fastened to the wall.Most murphy bed manufacturers

    do not require professional installers;in fact, they encourage DIY construc-tion. Product options range from basiclift-mechanism kits, which cost $250 to

    $300 and require you to build the bedframe and cabinet from scratch, tocomplete ready-to-install beds thatcost several thousand dollars.I chose to use a piston-mechanism

    kit manufactured by Create-A-Bed Inc.of Louisville, Kentucky. The kit costs$279 and includes all necessarymechanical hardware, building plans fora bed and bookcase and a videotape thatdemonstrates the construction processand building techniques.One of the benefits of this bed sys-

    tem is that you dont need many tools tobuild it. You will need basic hand tools(a tape measure, a hammer, clamps,etc.), a table saw or circular sawequipped with a sharp plywood-cuttingblade and a drill/driver. A miter saw ishelpful for cutting pieces to length, butits not required.

    MaterialsThe bed in the Create-A-Bed design isbuilt from a combination of solid stockand veneer-core plywood or particleboard

    Keeping the cabinet a couple of feet fromthe wall, connect the piston to the lower andthen upper ball-stud plates. The bed is tilteda few inches beyond vertical to make theupper connection. Safety note: Do not oper-ate the bed until it is secured to the wall.

    Drive 3-in. coarse-thread screws through the header and into wallstuds. Secure a full-size bed to at least three stud locations.

    Tilt the cabinet side panels upright,and attach the headboard with 2-in.screws and the cabinet header assem-bly with 1-1/4-in. screws. No glue isused to assemble the cabinet, makingit simple to disassemble and move.

    How a murphy bed worksA murphy bed closes with the assistanceof a spring or piston mechanism. The bedI built uses a piston system. The piston iscompressed when the bed is open (left).When the bed is closed the pistonextends, exerting force to help lift theweight of the bed. DC

    Anchoring a murphy bedIt is critical that you properly anchorthe bed cabinet to the wall. Here arethe three most common wall materi-als that you will encounter and thecorrect anchor to use in each case.

    material, such as melamine. Differentbuilding plans are provided depending onthe combination of material, bed size andorientation that you choose.I built a full-size vertical bed with

    one 24-in.-wide bookcase using cherryplywood and solid cherry. It requiredfive sheets of 3/4-in. cherry plywood,one sheet of 1/4-in. cherry plywood,two sheets of 1/4-in. birch plywood,about 24 lineal ft. of 1x4 solid cherryand 14 pieces of 1x2 x 8-ft. solid poplar.Create-A-Beds cabinet is designed

    to look like a closet with bifold doors,but I wanted to create a more modernstyle. With the approval of the manufac-turers technical advisor, I modified thefront panel and leg to suit my taste (seeOur Design Modifications, p. 38).The change had little effect on thematerial requirements.

    Safety note:Murphy bed lift systemscreate strong forces on the structure. Besure to check with the manufacturerbefore making any changes to the design.

    Building the bedThe construction process is not difficult(see how-to photos beginning on p. 34).The biggest obstacle for many peoplewill be finding enough space to work.You need a large, flat work surface a full sheet of plywood is just the rightsize. The finished bed is large, so if youhave a narrow hallway or stairway tocontend with, consider machining andfinishing the parts in your shop orgarage and assembling the bed in itsdesignated room.

    Most of my building time was spentcutting and finishing the large plywoodpieces before assembly. I used a tablesaw to cut the plywood, but you couldalso use a circular saw with a straight-edge guide.

    Tip:When you cut plywood witha table saw, keep the good side of theplywood faceup; when you use a circu-lar saw, keep the good side of the ply-wood facedown.Cover all of the plywood edges that

    will be left exposed with heat-activatededge banding, which is sold in rolls (seeSOURCES). Cut each strip of edgebanding a couple of inches longer thanthe plywood edge. Press the edge band-

    ing along the plywood edge with a hothousehold iron. (Protect the face of theiron by covering it with aluminum foil.)While the edge banding is still hot, pressit down with a roller or scrap of wood.Allow it to cool for a few minutes andthen trim off the excess with a utilityknife, chisel or special edge-bandingtrimmer, also available where edgebanding is sold.Fasten the bed hardware and then

    remove it before sanding and applyingthe finish. The manufacturer providesdetailed diagrams that show where eachpiece of hardware is located.After sanding, I chose to apply three

    coats of wipe-on polyurethane finish to

  • all of the panels before assembling thembecause it is easier to work on the flatpanels individually. Mask over or leaveunfinished any areas where glue willbe applied, such as along the bottom1-1/2 in. of each rail and the inside facesof the face panels.After the finish is dry, reattach the

    hardware and begin assembling the bed.The bed frame and rails are joined withsimple butt joints fastened with glue andwood screws or finish nails. Drill coun-tersinks and pilot holes for each screw.The last step before installing the bed isto attach the face panels to the frameand rail assembly.

    InstallationInstalling the bed and cabinet are proba-bly the easiest parts of the project, butthey are also the most important forensuring safe operation.Finish assembling the cabinet and

    bed frame a couple of feet away fromthe wall. Connect the pivot hardwareattaching the headboard and cabinet topwith wood screws.

    Connecting the pistons to the ball-stud plates is the final step beforesecuring the cabinet to the wall. Thepiston is labeled to show the correctinstallation orientation. Close the bed afew inches beyond vertical to snap thepiston onto the ball-stud plates. If thepiston does not fit, double-check theball-stud and pivot-hardware locationsand adjust them if necessary.The cabinet must be properly fas-

    tened to the wall for safe operation.When a murphy bed is in the open posi-tion, the lift mechanism is storing theenergy that will be used to help lift thebed. If the cabinet is not properlysecured, the lift mechanism could pull thecabinet away from the wall and down ontop of the bed.Use the appropriate type and number

    of fasteners for the size of bed you areinstalling and for the rooms wall framing(see Anchoring a Murphy Bed, p. 37).Drive one fastener into each stud locatedbehind the bed, or drive masonry anchorsat 16-in. intervals in masonry walls. Usethree anchors for a twin or full-size bed

    and four for a queen-size bed.Once the bed is secured to the wall,

    it is ready for the mattress. The bedframe will be a little difficult to pulldown without the mattress. Get a helperto assist you in holding the bed framedown and placing the mattress. If the bedfloats above the floor, more weight isneeded under the mattress. A simplesolution is to fasten a 2 x 4-ft. scrap of3/4-in. medium-density fiberboard tothe plywood panels under the mattresswith 1-1/4-in. screws. Once the bedframe stays down on the floor, the bedis ready for use. u

    Aluminum AccentsAluminum strips are attached betweenthe face panels as a decorative accent.You can purchase aluminum at a met-alworking or metal supply shop. Whenwe bought aluminum, the supplier cutit to length, and we drilled countersinksand pilot holes through each strip forNo. 6 screws.

    Tip: Use a carbon steel drill bit tobore through aluminum. To cut alu-minum, use carbide-tip saw bladesdesignated for nonferrous metals (met-als that dont contain iron).
