Bed Cabinet Assembly Instructions
1. Cut panels exactly as specified in the Cut List
located on page page 5(reg leg), page 20
(extended leg) and page 21(Long Leg) of these
instructions. As you cut each piece, identify it using
a pencil, as indicated in Figure 1. Label the Bed
Panels (not shown in Figure 1) BED PANEL. You
will use these names throughout the instructions to
reference the particular items.
2. Clean and/or sand pieces. Tape the following
edges that will be exposed after construction:
TOP STRETCHER & SIDE PANELS –front
edges
HEADBOARD –both long edges
BOTTOM STRETCHER –top edge
KICK –both long edges (to prevent bowing)
FACE PANELS –all four sides
Helpful Hint: The simplest method is to use pre-
glued, iron-on tape appropriate for the construction
material you are using.
3. Make a small mark on the inside of each Side
Panel, 3″ from the back and 18″ from the bottom.
From this mark measure up and back 147/8″ to the
back edge of the Side Panels. Make another mark
and pencil a line to indicate the back of the
Headboard Position.
4. Attach 1″ x 1″ x 1¾″ assembly brackets to the
Headboard, Bottom Stretcher and Kick as per
Figure 1. Note that you must set the top brackets
of the Headboard low enough so they do not
protrude beyond the back of the cabinet. If you will
be notching out Side Panels to accommodate a
baseboard, attach the Bottom Stretcher. Brackets
to the front side of the notches.
5. Accurately mark the Lift Mechanism mounting
holes on the inside of each Side Panel. See
Figure 2 for the layout of these holes. When
drilling the holes, first drill a 1/16″ hole with a 5/16″
bit. Countersink (5/8″ diameter) each hole on the
outside of the panels, just deep enough for the
head of the 5/16″ x 1¼″ flathead slot machine screw
to sit flush with the surface. (You can sand and
paint the machine screws’ heads to match your
Cabinet finish.)
6. Align the back edges of the Top Stretcher and the
Side Panels and clamp with 72″ bar clamps. Using
a 3/16″ (5mm) bit, drill three Confirmat screw holes
per side to a depth of 2″. Keep the outer holes 1″
away from the front and back edges of the Top
Stretcher. Center the third hole between them. Un-
clamp and re-drill the Side Panel (shank) holes
using a 9/32″ (7mm) drill bit. Do not countersink
these holes. See Figure 3.
7. Prior to assembling the Bed Cabinet, you may
wish to apply your choice of finish to the individual
pieces.
8. You can now begin assembling the Bed Cabinet –
if possible, do this in the room where you will
install the Bed Cabinet. Refer to Figure 1 for
positioning and dimensions. Prop up one Side
Panel and the Top Stretcher on their back edges
and attach with Confirmat screws. Attach other
Side Panel. Press-fit the Confirmat caps.
Helpful Hint
Before you begin, you may wish to visit our website at
www.murphybeds.com to view the Quick Time
Video showing the assembly of an Elite Aluminum
Frame. Please note that your Supreme Steel Frame
does not require the adhesive tape on the frame and
stiffeners, and the Supreme Steel stiffeners are
attached side to side.
Please Note:
Be sure to use the section of the Bed Frame Cut List
that corresponds to the size of the bed that you are
constructing.
Do not glue the Bed Cabinet together.

the Lift Mechanism mounting holes. Take horizontal measurements from finished front edge.
9. Attach Bottom Stretcher, Kick and Headboard using #8 x 5/8″ panhead screws. If installing the
Cabinet in a carpeted room, raise the Kick so that it sits lightly on top of the carpet. However,
under no circumstances raise the Kick more than ¼″, or it will interfere with bed
operation.
IMPORTANT NOTICE:
See Page #21 for mechanism drill instructions when using the EXTENDED LEG option.
See Page #22 for mechanism drill instructions when using the LONG LEG option.

Securing the Bed Cabinet
1. Remove the strip of baseboard where you wish to locate the Cabinet (or notch out the Side Panels)
so that the back of the Cabinet is flush against the wall. (Later you can trim and replace the
baseboard). Place Cabinet against the wall. If the floor is off-level or not square with the wall, shim or
pack the Cabinet with thin strips of wood. Do a preliminary for squareness by measuring diagonally
from corner to corner across the face of the cabinet. It is more important that the cabinet be square
than exactly level or plumb.
2. Use a step ladder to access the wall above the Top Stretcher and locate three studs or some other
solid structural members to which you can fasten three 2″ x 2″ L brackets (see Figure 4). Do not
place weight on the Top Stretcher when attaching the brackets, or it will “bow.”
Figure 4. Securing the Cabinet.
3. Drive two #8 x 2″ flathead wood screws through each bracket and into each solid framing member.
Drive a single #8 x ¾″ flathead screw through the middle bracket and into the Top Stretcher, then
recheck the Cabinet for square as in Step 1 above. Adjust as necessary and drive five more #8 x ¾″
flathead screws through the brackets and into the Top Stretcher.
4. Peel off the backing and attach Warning Label and three ¼″ round Bumper Buttons (see Figure 4).
Attention!
You must secure the Cabinet to solid structural members and not merely to the wall finish. If you are
not attaching your bed to a wood stud wall, see your local hardware retailer for metal stud screws or
concrete 1¾″ x ¼″ expansion bolts and a concrete drill bit. In either case, be careful not to hit
electrical wiring or plumbing behind the drywall.

Installing Springs in Lift Mechanisms
1. The number of springs in the Lift Mechanism required varies with the different weights of mattresses
and construction materials. Select the appropriate number from the chart below.
Bed Size
Bed Panel Material
Wood Veneer/Plywood Core
Melamine/Particle Board
Single/Twin
4–5 springs per side
5–6 springs per side
Double/Full
6–7 springs per side
7–8 springs per side
Queen
8–9 springs per side
8–9 springs per side
Table 3a. Use bed size to determine required number of springs
2. Since Figures 5 and 6show the Right Lift Mechanism, start with that one. Numbering down from the
top, the center line runs through spring hole #5. If you are installing an even number of springs, start
at hole #4 or #6, leaving hole #5 vacant. Notice that the hook ends of the spring have slightly
different sized openings. Hook the end of the spring that has the smallest opening under the
upturned edge of the Mounting Plate. Lay the spring down and slide it under the matching hole in the
Tension Arm. Be sure to install the springs so that the hook openings face you. See Figure 5 for
further detail.
Helpful Hints
You may find it easier to fit the hooks under the Tension Arm if you pry up the Arm Bracket with a
wooden wedge or similar device.
While an equal number of springs on each side of the centreline is preferred, an imbalance by one
spring is acceptable, preferably with the extra spring on the top side. If required, install spring #9 last
(see Figure 5).
Figure 5. Installing the Springs, Right Lift Mechanism.
Please Note:
After you have completed installing and checking the operation of your Murphy® Wall-Bed, you may find
it necessary to add or remove springs to achieve the correct lift effort of between five and 10 lbs. Please
refer to additional notes for tips on how to correctly balance your mattress.
If using SUPER SPRINGS please refer to the
“IMPORTANT NOTICE FOR SUPER SPRINGS” at page 11.
