Top Questions
Think of it as a box spring, but without the springs. A mattress foundation is slatted and ensures your mattress is properly supported. It provides a solid surface for your mattress and prevents sagging.
We don't recommend placing the foundation directly on the floor. The Lull Foundation is designed to be used like a box spring and is compatible with most bed frames. Add optional legs to transform your mattress foundation into a platform bed frame.
We recommend using the Lull Mattress Foundation with your Lull mattress. Like a box spring, a mattress foundation raises the mattress making it easier to get in and out of bed. It also absorbs movement, reduces wear, and creates a flat and firm structure for the mattress to rest on.
