Frequently asked questions
A foundation can be covered in fabric or have an exposed wood frame, with a solid top or one made of wood slats. The main purpose of a mattress foundation is to raise your sleeping surface to a comfortable height and give your mattress optimal support.
In the past, box springs used to be made of wood and filled with metal coils to add a springy flexibility and cushioning to the thin, stiff mattresses of those days. Nowadays, what some people still call "box springs" are more accurately called mattress foundations or bed foundations. They don't contain metal springs anymore, but serve the same purpose of making your bed setup more comfortable and supportive.
No. A platform bed with a solid or slatted surface doesn't require the addition of a mattress foundation. Always check your mattress specifications to make sure your bed setup works with your new mattress.
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 mattress 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 the look your mattress.
You won’t need the Saatva mattress 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 frame, 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.
Some people use what's called a bunkie board under their mattress to give it additional support. This a thin piece of material, often plywood or particleboard, that can be used with any type of bed setup, whether it's an old box spring, foundation, or a slatted platform bed frame. You don't need to add a plywood support on our Saatva mattress foundation as it already provides the optimal support your mattress needs.
Yes. Our standard metal frame has a plate at the top for headboard attachments. Please check with the manufacturer of your headboard to make sure it's compatible with your metal frame.
