Southerland 9-Inch Steel Foundation

The Southerland 9-Inch Steel Foundation provides rigid, heavy-duty support for all mattress types, including memory foam, latex, hybrid, and traditional innerspring. Engineered as a standard-height profile, this foundation lifts mattresses to traditional bed height while preventing middle-sagging, bowing, and structural wear over time.

Key Features & Highlights

• Heavy-Duty Steel Core: Constructed with high-gauge tempered steel support components to absorb pressure and maintain structural integrity without squeaking.

• Zero-Sag Design: Eliminates standard flex and bounce, extending the life of your mattress warranty by providing a flat, rigid surface.

• Standard 9-Inch Profile: Restores traditional bed height when paired with lower-profile bed frames or standard mattresses.

• Formaldehyde-Free & USA Made: Built without harmful chemical off-gassing and constructed in the USA by skilled craftsmen.
