Abstract
In one preferred form there is provided a mattress (10) for a bed. The mattress (10) includes an upper layer (12) formed from visco elastic foam material of a first kind; an intermediate layer (14) formed from visco elastic foam material of a second kind; and a lower layer (16) formed from foam material of another kind. The intermediate layer (16) is provided between the upper layer (12) and the lower layer (16). The upper layer (12) and the intermediate layer (14) have a combined thickness of at least 50 mm. The lower layer (16) has a thickness of at least 70 mm.
