About this product

Introducing the multi-award winning Sleep Firm Mattress with Exclusive S+ Pro 5 Zone Independent Spring System designed for sleepers looking for straight out firm support without feeling like they are sleeping on the floor. This Australian Made Mattress in a box is an Australian first and is designed specifically for those sleepers who prefer a firm support and comfort layer. The Sleep Firm has been designed and manufactured by the award-winning team at Chiropedic. With extensive knowledge within the mattress industry spanning over 100 years, you will sleep well, knowing you are sleeping on superior experience and quality. 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 specifically placed 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 breaking the 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. Above the S+ Pro spring is the Sleep Firms exclusive Boomerang Foam which has been specifically designed and engineered for a compressed mattress. 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. The top layer of the Sleep Firm Mattress is made using a high grade Adaptive knitted fabric combined with quilted 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. To ensure a firm supportive edge to encase the S+ Pro Spring and to prevent any roll-off, we also use the Boomerang Foam to create a foam box edge around the full perimeter of the mattress. A foam box technique is something you would find in a traditional retail store pocket spring mattress. 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. For peace of mind, the Sleep Firm Mattress comes with one of the best warranties on the market for a mattress in a box. We know this is a quality Australian made mattress manufactured using only the best materials, and as such, it comes with a 15-year Warranty.
