Low Profile 5" Flat Foundation by Stearns & Foster
Low profile 5-inch rigid flat foundation. Provides the support surface your S&F mattress requires for proper performance and warranty compliance.

The right foundation protects your mattress.
A proper foundation is not optional. It preserves your warranty and ensures your mattress performs as designed.

Warranty Preservation
Using the correct foundation preserves your Stearns & Foster warranty. Improper support — sagging slats, old box springs, incompatible frames — is one of the most common reasons mattress warranties are voided.
Mattress Performance
The IntelliCoil HD system is engineered to perform on a rigid, flat surface. A proper foundation ensures the coils respond correctly and the PrecisionEdge system maintains full edge support.
Lower Bed Height
At 5 inches, this foundation keeps your total bed height 4 inches lower than the Standard 9-inch. Ideal for modern aesthetics, platform-height beds, or easier entry and exit.
Built to support your investment.
A purpose-built 5-inch foundation for Stearns & Foster mattresses.

Solid Hardwood Frame
Kiln-dried hardwood frame engineered for decades of nightly use without developing flex, creak, or structural fatigue.
Steel Center Support
Steel center beam and cross supports distribute weight evenly across the entire frame, preventing sagging even under heavy mattresses.
Flat Support Surface
A solid, flat top surface provides uniform support across every square inch. No slats, no gaps — the rigid surface IntelliCoil HD mattresses require.
Durable Fabric Cover
A durable fabric cover protects the foundation and provides a clean, finished appearance.
Simple setup, reliable support.
Free White Glove Delivery
Free delivery with any mattress purchase. Our team sets up your foundation and mattress together in your room of choice.
Manufacturer Warranty
Stearns & Foster covers the foundation against manufacturing defects. LA Mattress Store coordinates any claims on your behalf.
Bed Frame Compatible
Fits all standard bed frames with center support. Also works on platform beds or directly on the floor.
