Introduction
The Smart Bed™ Universal Kit distributed by Lippert Components, utilizes a unique nylon strap-based
system, adaptable to a broad range of RV and heavy truck applications including cabs, living rooms, slide-
out rooms and master bedrooms. The straps retract into the bed base, concealing the lifting system in the
retracted position, permitting OEMs more floor plan design freedom. The nearly silent Smart Bed Lift
system is operated by a single motor that controls four support mounts to raise and lower the bed at 58.4
mm (2.3 inches) per second. The 362 Kilogram (800-pound) capacity system can be customized in both size
and configuration to maximize space in any motorhome, towable RV or truck cab floor plan design. The
system can even “bend” to conform to wall curvatures found in some motorhome cabs.

4. Starting at one end rail, insert a corner cap key (Fig. 2A) into each end of the rail (Fig. 2B).
5. Use a rubber mallet to make sure the corner cap keys are connected tight within the end rail.
NOTE: The end rails should stop at the notched top (Fig. 2C) and bottom edge of the corner cap (Fig. 2D).
6. Repeat step 4 and step 5 for the rest of the corner caps.
7. If the Smart Bed Lift configuration uses angled sides, assemble the joints together (Fig. 3A) and secure
with a bolt (Fig. 3B) and nut (Fig. 3C).
8. Insert the assembled angled joint into the side rails (Fig. 4). The end rails should stop at the notched
center (Fig. 4A).
9. Use a rubber mallet to make sure all the rails are tightly secured onto the corner cap keys and
angled joints.

Center Rail Support
1. Measure and mark the center of both end rails (Fig. 1A).
2. Attach the center rail support mounting brackets (Fig. 8A) to both ends of the center rail support
(Fig. 8B) with three #8 - 15 x 1.00" Phillips flat head screws (Fig. 8C).
3. Place the center rail support (Fig. 9A) at the center of the end rails (Fig. 9B) with the wide flat side of the
center support, facing down. Make sure to insert the center rail support into the top channel extrusion of
the end rails (Fig. 9C).
4. Insert the wood slats into place, see Slat Brackets and Wood Slats section.
NOTE: Secure the center rail mounting brackets (Fig. 9D) to the end rail channels only AFTER the wood
slats are completely in place. This ensures the center rail support is properly aligned and gives
sufficient play when hammering in the slat brackets.
5. Attach each end of the center rail support's mounting brackets (Fig. 9D) to the end rail's insert channels
(Fig. 9C) with two 3.9 x 9.5mm screws (Fig. 9E) into each end of the center rail support mounting
bracket and the end rail inner channel.
11. If applicable, bend the bendable flat bracket (Fig. 7A) to the desired angle for each joint assembly.
12. Place the bendable flat bracket centered over the assembled joint and just under the slat and insert
channel (Fig. 7B) on the side rail.
13. Install 12 rivots at each pre-drilled hole (Fig. 7C).
14. If applicable, repeat steps 11-13 for each support joint.

(Fig. 10B) with their curved side facing up, into the slat brackets.
2. Place the assembled brackets into the side rail insert channels with the bracket tabs (Fig. 10A) facing
down.
NOTE: The slat bracket assemblies should rest in the insert channels of the side rails and the center rail
support (Fig. 11) until all the slat bracket assemblies are in place.

drive pan head screws (Fig. 9E) into each end of the center rail support mounting bracket and
the end rail inner channel (Fig. 9C).
9. Using a pneumatic staple gun, attach the slat bracket holders (Fig. 14A) to the wood slats (Fig. 14B),
on both sides, one staple per wood slat (Fig. 14C).

edge of the outside rail.
6. Repeat steps 1-5 for the other stabilizer guide track bracket.
Mounting Channel Brackets
1. Insert the shorter, motor mounting channel bracket (Fig. 20A), into the end rail channel closest
to where the motor will be placed. Tip the topside up into the channel and then slide the motor
mounting bracket down into the bottom of the end rail channel.
2. Place one mounting channel bracket (Fig. 21A) into the side rail channel, closest to where the motor
will be placed. Tip the topside of the mounting channel bracket up into the top of the side rail channel
and then slide the mounting channel bracket down into the bottom of the side rail channel.
