Deciding whether you need a Saatva foundation or box spring for your new mattress depends on the kind of bed frame you plan on using (platform beds, for example, don't need a foundation), your existing mattress foundation or box spring, and whether or not you plan to use an adjustable base.
You will need the Saatva box foundation if:
- Your existing foundation or support system is more than 7 years old.
- Your existing support creaks, has soft spots, or is damaged in any way.
- You want a foundation designed to support your specific mattress.
Our Saatva HD, for example, requires pairing with our HD foundation for optimal support. - You want a foundation that matches your mattress. We use the same cover that's crafted from a soft, breathable blend that includes organic cotton for the Saatva box foundation as we do for our mattresses.
You won't need the Saatva box foundation if:
- You purchased a mattress support system within the last 7 years.
- Your existing foundation is in good condition and provides sturdy center support.
- You don't mind not having matching foundation.
- You have a platform bed, which does not require a foundation.
- You have an adjustable base, which takes the place of a foundation or box spring.
