Top Questions

What is a mattress foundation?

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.

Can I put the mattress foundation on the floor?

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.

Do I need a mattress foundation?

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.

Reviews

I waited too long

"This bed is excellent. i haven’t ever in my life slept so well. (reference 69yrs). I believe you will too. I purchased a Full Lull Mattress I believe it was the original but a step up . Included sheets, pillows, pillow covers and a mattress pad. Excellent product. I did buy a bed frame it was wooden. However, at the corners when I’d always clip the corners of my shins and it hurt or scratch/ cut me. Since I always moving to quickly and their is limited space between end of bed to dresser. This probably won’t happen to others. I was able to return frame and purchased a new padded one. Returns so easy. Great company"
