Saatva foundations are sold separately, as not all of our customers have the same needs.
A foundation serves the same purpose as a box spring. The difference is that our foundation does not use springs but rather a more stable and durable slat system to support the mattress.

We also offer a line of bedroom furniture, including several bed frame options. Shop our bedroom furniture here: https://www.saatva.com/furniture
NOTE: Our platform bed frames do not require the use of a foundation. The mattress sits directly on the slats or solid platform surface.
