Serta iComfort low profile box spring foundation is a great option to support your mattress.
A box spring foundation goes underneath your mattress and on top of your bed frame. It is important to have this support in between to prevent your mattress from sagging and breaking down over time. Most manufacturer warranties are void without a proper foundation like a box spring.
This foundation measures approximately 5″-6″ high and is ideal for extra loft mattress heights such as super pillowtop mattresses or a high bed frame.
Please note that a King size box spring is 2 pieces (two TwinXL).
