Claim Text:
1. A mattress comprising: a viscoelastic foam layer having a first thickness separating a body facing side and a ground facing side opposite the body facing side, the viscoelastic foam layer proximal a sleeping surface; an intermediate layer having a body facing side and a ground facing side opposite the body facing side, the intermediate layer comprising a reticulated polyurethane, non-viscoelastic open cellular structure foam between a first spring layer and a second spring layer, the first spring layer has the body facing side proximal the ground facing side of the viscoelastic foam layer and the second spring layer has the ground facing side, the intermediate layer having a second thickness and wherein the first spring layer and the second spring layer of the intermediate layer are each no more than about 6.4 cm thick; a polyurethane foam support layer distal the sleeping surface, the polyurethane foam support layer having a third thickness greater than the first and second thicknesses; and a foam sidewall extending from the body facing surface of the first layer to the ground facing surface of the third layer, wherein the foam sidewall comprises an open cell foam at least proximal to the reticulated polyurethane, non-viscoelastic open cellular structure foam between the first and second spring layers, wherein the reticulated polyurethane, non-viscoelastic open cellular structure foam and the foam sidewall aligned with the reticulated polyurethane, non-viscoelastic open cellular structure foam form an air channel wherein motion of the first spring layer and the second spring layer cause air flow in the air channel.
