This Limited Warranty and other performance warranties are based on tests conducted on “sets” that consist of our mattresses and our foundations.

Sealy makes no representations whatsoever as to the structural integrity or rated load for any frame not manufactured by or for Sealy. Coverage under this Limited Warranty is excluded if the frame is determined, in Sealy’s reasonable discretion, to be inadequate or if the foundation is found to be in an unsanitary condition.

    This Limited Warranty covers the following items during normal wear:

    Structural damage or broken components.
    Squeaks or rattles.
    Sagging that is not associated with use of an improper bed frame.
    This Limited Warranty does not cover:

    Structural damage from using an improper bed frame.
    Physical abuse or damage to the structure and/or cover material of the foundation, including but not limited to burns, cuts, tears, or liquid damage.
