u Carefully check the contents of your mattress boxes
u Orientation
These instructions refer to “left” and “right” as if you are standing
at the head of the bed looking toward the foot of the bed.
u Using a Surge Protector
While the Firmness Control™ System may be plugged directly into
a wall outlet, we recommend using a surge protector to guard
against unexpected power surges. We recommend using a surge
protector that is listed to UL® 1449 with a clamping voltage of
330 volts, and a joule rating of 700 or higher.
Please note: your 20-year Limited Warranty does not cover damage
to the Firmness Control™ System due to a power surge, regardless
of the source. See the Limited Warranty on page 37 for more details.

“ This is the first time in three
years that I slept through the
entire night without getting up
two or three times. I’m thrilled
and amazed! Unbelievable! I wish
we had purchased your sleeping
system years ago.”
- Keith Fisher, Jackson, MI
