I claim: 1. A pillow top layer for a support cushion, the pillow top layer comprising: a first elongated foam portion having a first side opposite a second side, and upper and lower faces extending between and connecting the first and second sides; a second elongated foam portion having a third side opposite a fourth side, and upper and lower faces extending between and connecting the third and fourth sides, the first and second foam portions being positioned together in a generally parallel arrangement such that one of the first side and second side is generally parallel and adjacent to one of the third side and fourth side, the upper faces of both first and second elongated foam portions collectively defining a substantially planar top surface of the pillow top layer; and a cover that substantially covers the first elongated foam portion and the second elongated foam portion wherein the cover substantially separates the first and second elongates foam portions, wherein the cover, the first elongated foam portion and the second elongated foam portion define a generally contiguous and substantially gapless structure, and wherein the pillow top layer is positioned adjacent an elastic core having length and width dimensions, and wherein the first elongated foam portion and the second elongated foam portion substantially cover the width dimension of the elastic core. 2. The pillow top layer of claim 1, wherein at least a portion of the cover generally separates the first and second elongated foam portions from the elastic core. 3. The pillow top layer of claim 1, wherein the elastic core has a greater hardness than the first and second foam portions. 4. The pillow top layer of claim 1, wherein the first and second elongated foam portions comprise viscoelastic foam. 5. The pillow top layer of claim 1, where the first and second elongated foam portions have a thickness of between two and seven centimeters. 6. A pillow top layer for a support cushion having an elastic core having a length and a width wherein the length is greater than the width, the pillow top layer comprising: a plurality of foam portions, each of the plurality of foam portions having a length, a width, and a thickness, the width of each foam portion is substantially the same as the width of the elastic core and greater than the length of each foam portion, wherein adjacent portions having substantially planar facing sides positioned side-by-side to define a substantially gapless structure, wherein the combined length of the plurality of portions is substantially the same as the length of the elastic core; and a cover extending between adjacent foam portion of the pillow top layer that generally covers the elastic core and the foam portions. 7. The pillow top layer of claim 6, wherein the cover defines at least one sleeve that substantially covers at least one of the plurality of foam portions. 8. The pillow top layer of claim 6, wherein at least a portion of the sleeve generally separates the first and second elongated foam portions from the elastic core. 9. The pillow top layer of claim 6, wherein the elastic core has a greater hardness than the plurality of foam portions. 10. The pillow top layer of claim 6, wherein the plurality of foam portions comprise viscoelastic foam. 11. The pillow top layer of claim 6, where the plurality of foam portions each have a thickness of between two and seven centimeters. 12. The pillow top layer of claim 6, wherein the plurality of foam portions substantially cover the elastic core. 13. A support cushion comprising: an elastic core having a first surface, a second surface and a thickness defined between the first surface and the second surface; a first cover portion substantially entirely enclosing the elastic core; a pillow top surface adjacent the first surface of the elastic core, the pillow top surface including a plurality of foam portions; and a second cover portion at least partially covering the pillow top surface, the second cover portion attached to at least one of the first cover portion and the elastic core. 14. The support cushion of claim 13, wherein the second cover portion is releasably attached to the first cover portion. 15. The support cushion of claim 13, wherein the foam portions are positioned side-by-side to substantially cover the first surface of the elastic core. 16. The support cushion of claim 13, wherein at least one of the first and second cover portions separates the foam portions from the elastic core. 17. The support cushion of claim 13, wherein the second cover portion includes at least one sleeve that at least partially houses at least one of the foam portions. 18. The support cushion of claim 13, wherein the foam portions comprise viscoelastic foam. 19. The support cushion of claim 13, wherein the foam portions each have a thickness of between two and seven centimeters. 20. The support cushion of claim 13, wherein the elastic core has a greater hardness than the foam portions.
