S+ Pro 5 Zone Independent Spring System

The core of this mattress is the exclusive S+ Pro 5 Zone Independent Spring System. Designed for advanced strength and spinal alignment, each Independent Spring is placed explicitly within each of the 5 Zones to ensure it responds and supports the natural contour of the spine and body. For added strength, durability and longevity each spring is individually wrapped in N-100 Medical Grade Fabric which is 42% stronger than any regular pocket spring.

To achieve its advanced strength, the S+ Pro Spring has a super high spring count spread out across the 5 Zones. This ensures maximum support for the body and spine by the placement of spring into multiple levels. Firm Support is provided for the head, lower back/hips and the feet. Slight pressure relief is then provided for the shoulders and knees for comfort.
