S+ Pro 5 Zone Independent Spring System

At the core of this mattress lies the exclusive S+ Pro 5 Zone Independent Spring System, meticulously designed to ensure spinal alignment and advanced strength. Each Independent Spring is placed within its designated zone, allowing it to respond and support the natural contours of the body and spine. To ensure durability and longevity, each spring is individually wrapped in N-100 Medical Grade Fabric, which is 42% stronger than regular pocket springs.

To maximize support for the body and spine, the S+ Pro Spring features a super high spring count distributed across the 5 Zones. This multi-level approach provides firm support for the head, lower back/hips, and feet, while also offering slight pressure relief for the shoulders and knees to enhance comfort.

Boomerang Foam

The Sleep Firm's exclusive Boomerang Foam is placed on top of the S+ Pro spring and has been engineered to suit compressed mattresses. This premium density foam possesses an extremely high rebound level that maintains its firmness, ensuring long-lasting support. The Boomerang Foam by Dunlop is Geca Certified and treated with Ultra Fresh, making it anti-microbial. Furthermore, it is a Dunlop Approved foam and has received the National Asthma Council Sensitive Choice certification.

Bekaert Deslee Adaptive Fabric & Quiltec Foam

The top layer of the Sleep Firm Mattress is made using a high grade Adaptive knitted fabric combined with quiltec foam which works to eliminate body impressions within the quilting. Made with a Variable Pressure Foaming process, its open cell structure provides excellent moisture dissipation through the top quilted layer of the mattress. The Adaptive fabric by Bekaert Deslee responds dynamically to temperature changes and keeps your sleep environment cool and dry, all night, every night.

Foam Box Edge

To prevent roll-off and provide firm support for the S+ Pro Spring, the mattress features a foam box edge made with Boomerang Foam that encases the full perimeter. This foam box technique is commonly utilized in traditional retail store pocket spring mattresses.

3D Spacer Fabric

For the sides of the mattress, the Sleep Firm uses a 3D Spacer fabric which is designed to ensure maximum air circulation around the sides of the mattress.
