If you want a foundation, we recommend our Avocado Green Mattress Foundation.
You can use a foundation with our mattresses, but it is not required (many modern bed frames do not require them). A reminder that a foundation and a box spring are not the same. A foundation is a rigid structural support for a mattress. Think of a foundation as a solid, empty box. A box spring, in contrast, actually contains springs. We do not recommended a box spring. A box spring will make our mattress — which already contains a pocketed innerspring unit — very bouncy.
Foundations Are Not Required, But Work Great
Some Avocado customers opt for foundations to allow them to place their new mattress on a bed frame (which has side rails, but limited interior support) or a traditional bed, where an additional layer is needed for support or desired for aesthetic reasons. That's why we created our Avocado Green Mattress Foundation. It's made with FSC® certified (C156318) wood and GOTS organic certified cotton — plus it's GREENGUARD Gold certified by UL Environment for low emissions.
