1. A side rail assembly for supporting an edge of a mattress, comprising:
a multilayered structure comprising layer of a polyurethane foam comprising an open cellular structure, wherein the open cellular structure comprises about 10 to about 40 cells per inch, a hardness of about 35 pounds-force to about 100 pounds-force, and a density of about 1.2 pounds per cubic foot to about 2.0 pounds per cubic foot, wherein a percentage of intact windows between adjacent cells in the open structure is less than about 50%, wherein the layer is configured to be disposed about a perimeter of an inner core free of open channels, of the mattress and is configured to permit the flow of fluid from and to the inner core through the layer, and wherein the multilayered structure is configured to contact only sidewalls of the inner core.
