All your questions answered
Do I need anything else to support my mattress?
Yes, we recommend you add a flat, sturdy support like a foundation to your mattress when using our metal bed frame. The Leesa foundation was designed to support all Leesa mattresses.
What's the difference between a platform bed, a foundation, and a box spring?
Both a box spring and a foundation support your mattress and lift it off the ground. A box spring is made with actual springs, while a foundation is usually made with slats. Both are recommended for use with a bed frame. A platform bed is a piece of furniture that gives your mattress the support it needs. With an aesthetically pleasing design and its own legs, a platform bed eliminates the need for a bed frame.
What is the Adjustable Base?
The Adjustable Base is a frame specially designed to lift the top and/or bottom of the mattress to create a custom sleep experience. This capability makes is easier for activities like reading, watching TV, and working from the comfort of your Leesa sleep setup!
Do I need tools to put the Leesa Foundation together?
The foundation consists of four outer rails held together by pins and a center rail that slides into place. No Allen wrench or power tools needed. If you're unsure about how to set up your foundation, give us a call or send us a message. We're here to help!
Do I need a bed frame?
It is entirely up to you to set your Leesa mattress up with a bed frame. We recommend one, as it will help your mattress reach its full potential, building a better bed from the ground up.
Bed frames are commonly used to position a mattress and foundation, so they stay in place and are lifted off the floor. When putting up a headboard or canopy, both necessitate the use of a bed frame.
We strongly advise you to use a stable, rigid base for your Leesa mattress, whether it's our traditional metal bed frame with a Leesa foundation, a Leesa platform bed, or a slatted bed.
Do I need a frame for my platform bed?
Nope! The Leesa platform bed is all you need, no additional bed frame or foundation required. Just top your platform bed with your Original, Sapira Hybrid, or Legend Hybrid mattress.
