Better-than-box-spring support: Designed for bed frames that lack supportive slats such as panel bed frames, the Flat Foundation provides your mattress with the support it needs — minus the noisy coils, bulky structure, and prone-to-sag nature of traditional box springs.

Lightweight + easy-to-assemble: A collapsible, accordion-style design equipped with slats that effortlessly snap into place and a zip-on cover ease setup, breakdown, and transport with no tools necessary. Set up in seconds, move painlessly, and wish good riddance to the bulk of the past.

Strong. Durable. Long-lasting: A solid steel frame with an above-industry-standard 14 slats supports up to 2000 lbs. (or 34 Golden Retrievers), providing sturdy, silent support with no unstable shaking or mattress slippage for many nights to come.

Better together: The Purple Flat Foundation is strong, sturdy, and specially designed to support Purple mattresses — while also being easy to assemble. With lasting durability, a great night’s sleep with no creaks, squeaks, or sagging is here to stay.
