Abstract
A matress formed from foam material is provided. The mattress generally comprises a foam body having an upper surface for supporting a user and a lower surface for resing on a support. An inner core region formed from foam material having a greater Indentation Force Deflection (I.F.D.) co-efficient than the remainder of the foam body is provided therein. The inner core region extends substantially along the length of the mattress and provides greater support in the mattress along an axis substantially parallel to the longitudinal axis of the mattress.
