What is a foundation for a bed?

A foundation supports, raises, and houses your mattress, consisting of a frame and slats. Foundations are firmer bed bases than box springs because they are spring-less, which makes them a solid base for your foam or hybrid mattress.

No Time? No problem.

Assemble in minutes—no tools necessary! Everything you need for setup is included in the conveniently sized box. The simplicity is snooze worthy.


Easy elevation

Complete your upgrade by adding our bed frame (sold separately) to lift your bed setup 7" off the ground. A perfect combo if you move often or want the simplest bed setup.
