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.

All the customers should retain the original packaging of the mattress at least for 150 nights to use it during the return process. We highly recommend using a mattress protector with your mattress.
