The TEMPUR-Flat Grey Foundation provides the flat, solid and sturdy base your mattress needs to provide the support you expect and deserve. Designed by Tempur-Pedic to be both stronger and more durable than any other support platform. You can choose which box spring profile suits your headboard and bed the best. Although low profile foundations may be 30% lighter than previous construction, there is no loss of weight capacity, strength or durability. Pricing will vary by size. The antimicrobial treatment hinders microorganisms, including dust mites!
