A ventilated mattress includes a top foam layer having a plurality of spaced apart holes which extend through the thickness of the top foam layer. The top foam layer rests upon a bottom foam layer which has an upward facing side which has a convoluted surface containing upward projections which are spaced apart by valleys, thereby creating structural passageways for air to flow into and from the holes. When a force, such as the weight of a person, is applied to the top foam layer, air flows out the sides of the mattress through air passageways created by the upward projections and valleys of the convoluted surface. Conversely, when the force is removed air flow into the sides of the mattress through the air passageways.
