We purchased 2 sets of the Sterns & Foster mattress and foundation. We have had them for 2 months and very happy with our purchase. Ordered on line, fast delivery, and delivery and haul away old sets went very smoothly.

Lower is Better

Sleepwell, Michigan
Works well as a foundation and because it is the shorter version, my comforter fits better. It is also nice to be closer to the floor

We chose the 5 inch as we are getting older and lowered our bed significantly. So easy to get in and out of bed.
