FAQs

What is the height of the Flat Mattress Foundation? 

The Beautyrest Flat Foundation has a height of either 5.5" or 9".

Can the mattress foundation be used with an adjustable base? 

No, it cannot bend and is made for bed frames that are meant to stay flat.

Do I have to use a Beautyrest base or foundation with my Beautyrest mattress?

Beautyrest mattresses and foundations are often times sold as a set because they are designed to pair together, and we can confirm their compatibility during quality tests. However, you are not required to use a Beautyrest foundation with your Beautyrest mattress. And as long as the foundation you currently are using is in good shape and uses consistent support it should pair just fine with your Beautyrest mattress.
