The Delta King single, from the Sealy mattress range is designed to support growing bodies. It features engineered technology that includes a PostureTech spring system that combines the best in comfort, support and conformance. The EdgeGuard is a built-in layer of extra support around the perimeter of the mattress that creates a firm seating edge and greater stability. As expected from all Sealy mattresses, the Delta is made from high quality foams and comfort layers for long lasting performance that are resilient and durable. Equally important is the HealthShield Antimicrobial treatment that guards and protects the outer fabric from bacteria and mould which results in a more hygienic sleep surface. The Delta is a firm-feel mattress that is proudly Australian made with an impressive 10-year warranty.
