Defective foundation X3

Mattress is great, but Tempur-pedic requires use of their foundation to have a valid warranty for the mattress. We have received THREE sequential Tempur-pedic queen 5” foundation replacements in 2013, all with defective ribs or horizontal wood strips/slats. One or both dislodge from the foundation box, making the foundation unstable. If you hear a creaking noise in your Tempur-pedic foundation, check for a broken rib by running your hand along the side. If the rib or wood strip/slat has dropped below the level of the foundation frame, it is broken, and you should contact Tempur-pedic customer service for a warranty foundation replacement. We have solid steel slats bolted to the bed sides with center feet, as recommended by Tempur-pedic, so our bed support for the foundation and mattress is not an issue.
