Zenhaven can be purchased as a set with a matching foundation. We generally recommend purchasing our entire system, but if your box spring or foundation is less than seven years old and in very good condition, meaning it's sturdy and does not sag or have any soft spots, it should work ﬁne. Your mattress warranty remains in place even when using your existing foundation or box spring. The same is true of an existing bed frame, provided it has vertical center support for queen and larger size mattresses.
Zenhaven can also be used on a solid platform bed. If the platform has slats, you must cover them with a layer of plywood or masonite board to create a solid surface.
