Sleep Firm Mattress Features:
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.
Super High Pocket Spring Count:
Single Mattress: 576 Springs
King Single Mattress: 741 Springs
Double Mattress: 900 Springs
Queen Mattress: 1092 Springs
King Mattress: 1326 Springs
Boomerang Foam
Above the S+ Pro spring is the Sleep Firms exclusive Boomerang Foam which has been specifically designed and engineered for a firm mattress in a box. This premium density foam has an extremely high rebound level that does not lose its hardness, ensuring long-lasting firm support.
The Boomerang Foam by Dunlop is GECA Certified and treated with Ultra Fresh, which is anti-microbial. It is also a Dunlop Approved foam with the National Asthma Council Sensitive Choice.
