1. A body support cushion, comprising: a layered arrangement of foam comprised of at least one layer of viscoelastic foam having a density of at least 20 kg/m3 and no more than 150 kg/m3; andphase change material in the layer of viscoelastic foam;wherein the layer arrangement of foam includes a first base layer, a first layer of viscoelastic foam adjacent the first base layer, and a second layer of viscoelastic foam adjacent the first layer of viscoelastic foam;wherein the first layer of viscoelastic foam includes reticulated foam; and,a mattress cover also comprising a phase change material wherein the amount of PCM in one area is greater than a second area. 2. The body support cushion of claim 1 wherein the phase change material includes a plurality of microspheres containing the phase change material, and wherein the microspheres are formed in the second layer of viscoelastic foam. 3. The body support cushion of claim 2 wherein the microspheres are spray-applied to an upper surface of the second layer of viscoelastic foam. 4. A body support cushion, comprising: a layered arrangement of foam comprised of at least one layer of viscoelastic foam having a density of at least 20 kg/m3 and no more than 150 kg/m3; and phase change material disposed in the layered arrangement of foam; wherein the layer arrangement of foam includes a first base layer, a first layer of reticulated viscoelastic foam adjacent the first base layer, and a second layer of viscoelastic foam adjacent the first layer of viscoelastic foam; wherein the first base layer includes first and second base layers stacked adjacently to one another; said first layer of viscoelastic foam having a first layer of said phase change material; one of said second layer of viscoelastic foam or said first base layer also having a second layer of said phase change material; wherein an amount of phase change material within at least one of said first and second layers of said phase change material varies within said at least one of said first and second layers to provide differing cooling capacities. 5. The body support cushion of claim 4 wherein the first and second layers are at least one of equal height and equal hardness. 6. The body support cushion, of claim 5 wherein the first and second layers each has a height between 8.00-12.00 cm. 7. The body support cushion of claim 6 wherein the first and second layers each has a height of 10.75 cm. 8. The body support cushion of claim 5 wherein the first and second layers each has a hardness between 100 N-200 N. 9. The body support cushion of claim 8 wherein the first and second layers each has a hardness of 150 N. 10. A body support cushion, comprising: a layered arrangement of foam comprised of at least a first base layer, a first layer of viscoelastic foam adjacent the first base layer, and a second layer of viscoelastic foam adjacent the first layer of viscoelastic foam with at least one of the first layer and second layer of viscoelastic foam having a density of at least 20 kg/m3 and no more than 150 kg/m3; and a phase change material layer applied to an upper surface of the second layer of viscoelastic foam opposite the first layer of viscoelastic foam such that the phase change material layer extends into the second layer of viscoelastic foam; wherein the first layer of viscoelastic foam includes reticulated foam; further comprising a mattress cover on said layered arrangement of foam, said mattress cover having a second phase change material, and wherein amounts of said second phase change material vary along an upper surface of said mattress cover. 11. The body support cushion of claim 10 wherein the first layer of viscoelastic foam has a thickness between 2.0 and 10.0 centimeters. 12. The body support cushion of claim 11 wherein the first layer of viscoelastic foam has a height of 7.0 centimeters. 13. A body support cushion, comprising: a layered arrangement of foam comprised of at least one layer of viscoelastic foam having a density of at least 20 kg/m3 and no more than 150 kg/m3; a first phase change material in the layer of viscoelastic foam; wherein the layer arrangement of foam includes a first base layer, a first layer of viscoelastic foam adjacent the first base layer, and a second layer of viscoelastic foam adjacent the first layer of viscoelastic foam; wherein the first layer of viscoelastic foam includes reticulated foam; and wherein the second layer of viscoelastic foam includes viscoelastic material having a density greater than the density of the first layer of viscoelastic foam; said second layer of viscoelastic foam having a second phase change material, an amount of one of said first phase change material and said second phase change material varying along a surface of the corresponding layer. 14. The body support cushion of claim 1 wherein the second layer of viscoelastic foam includes viscoelastic material having a density less than the density of the first layer of viscoelastic foam. 15. The body support cushion of claim 1 wherein the second layer of viscoelastic foam has a height no greater than the height of the first layer of viscoelastic foam. 16. The body support cushion of claim 1 further comprising an outer cover having an outer surface and an inner surface opposite the outer surface with a thickness of the outer cover defined therebetween. 17. The body support cushion of claim 16 wherein the outer cover includes phase change material. 18. A mattress comprising: a multilayer arrangement of foam layers with at least two layers of viscoelastic foam having a density of at least 20 kg/m3 and no more than 150 kg/m3, and wherein at least one of the viscoelastic layers is comprised of reticulated viscoelastic material; an outer mattress cover encasing the multilayer arrangement of foam layers; and phase change material contained in one of the at least two layers of viscoelastic foam and the outer mattress cover; wherein said phase change material varies along a surface of the at least two layers of viscoelastic foam and the outer mattress cover. 19. A mattress comprising: a multilayer foam arrangement comprised of a first non-reticulated viscoelastic layer, a second reticulated, viscoelastic layer, and a third non-reticulated non-viscoelastic layer; an outer mattress cover enclosing the multilayer foam arrangement; and phase change material, contained in the multilayer foam arrangement and the outer mattress cover; said phase change material in said outer mattress cover varying in amount along a surface to vary cooling capacity along the surface of said outer mattress cover.
