The Sealy Posturepedic Twin Foundation is a high-profile box spring designed to pair with Sealy Posturepedic twin mattresses, providing a stable and supportive base that extends mattress life and elevates sleeping height.
The foundation measures 74" x 38" for the twin size and raises the mattress up to 9 inches above the bed frame, making it easier to get in and out of bed. It is compatible with all standard twin bed frames and requires no assembly. A 10-year warranty backs the construction and durability of this foundation.
