Purposefully designed for sleepers who actively prefer a distinctly firm and stable sleep surface. Ultra-high-density comfort foams help limit surface sinkage, while extra-thick, triple-tempered pocket springs create a strong, responsive foundation underneath. Assured Firm has an extra-firm 9/10 feel with substantially less surface cushioning than Chiropractic Black Label or The Signature Mattress. It is formally endorsed by the Australian Spinal Research Foundation for spinal support and comfort.
