Assemble your bed frame if you have one
your foundation should be assembled directly onto your bed frame 
or on the floor. Some bed frames have slats that run from one side 
of the bed to the other. if your bed frame has slats, position the slats 
evenly to support the foundation. if your bed frame has fewer than 
three slats, we recommend adding additional slats to ensure 
adequate support for your foundation. 
Caution: With some styles of bed frames, the foundation length 
may extend beyond the frame’s support legs. This situation makes it 
possible for the frame to tip when significant weight is placed at the 
foot of the bed. Please use caution when sitting or placing weight 
on the foot of the bed when using these types of frames.

“ I assembled the Sleep Number
bed by myself. My wife was in 
doubt at first, but, after sleeping 
one night, she said it was magic 
how well she slept without back 
pain. Now we sleep longer and 
more comfortably than on any 
previous mattress we’ve owned.”
