Core Correct Mattress — full product details
The Core Correct Mattress is a firm Bonnell spring mattress built for support. A 15 cm interconnected coil system — reinforced with a border frame and butterfly edge support — sits beneath a quilted comfort top, giving an extra-firm, even surface in a low 19 cm profile. Our mattress buying guide covers the firmness, spring structure and materials in more detail.
It comes in five Australian Standard sizes — Single, King Single, Double, Queen and King — so there's a fit for a child's room, a guest space or a main bedroom. The extra-firm feel suits back and stomach sleepers, heavier sleepers, and anyone who prefers a very supportive surface to sleep on rather than sink into.
Core Correct suits anyone after a firm, supportive innerspring with reinforced edges, delivered ready to use. It arrives flat and full-size — not rolled or compressed — and works with any standard bed frame or base. See it in person at our showrooms in Rocklea, Sandgate, Bundall (Gold Coast), North Ipswich and Beenleigh.
