Frequently asked questions
The Saatva foundation comes with a 15-year non-prorated warranty. Please visit our full warranty page for details.
Saatva offers two foundation heights, 4.75” and 8.75.” There is no difference in quality or performance between the two heights; the choice is a matter of personal preference and the overall height of the bed setup you want. One consideration is whether you plan to use your existing bed skirt. The “drop” on a standard bed skirt is 14” to 15,” which works with the 8.75” foundation and a standard 7” bed frame.
Deciding whether you need a Saatva foundation for your new mattress depends on the kind of bed you have (platform beds, for example, don’t need a foundation) and your existing mattress support.
You will need the Saatva 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.
- You want a foundation that matches your mattress. We use the same organic cotton cover for the Saatva foundation as we do our mattresses.
You won’t need the Saatva 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 a matching foundation.
- You have a platform bed, which does not require a foundation.

Yes, you can order a split queen foundation to make delivery easier if you have an especially narrow staircase or hallway in your home. There is no difference in comfort or quality between a split queen foundation and regular foundation. Note: A split foundation is standard on king and California king sizes.
