Serta has joined forces with the National Sleep Foundation
(NSF) to design the all-new Perfect Sleeper�, the
Only Official Mattress of the National Sleep Foundation. The
Perfect Sleeper Leavenworth has all-new comfort and support
features, bringing you more advanced mattress technology at an
affordable price! This traditional plush model offers classic
tailoring, but with additional comfort layers at the top of
the mattress for a softer sleeping surface.
