A support cushion is provided for dissipating heat away from the support cushion. The support cushion includes a body supporting portion and a base portion that is positioned below the body supporting portion. The base portion defines a channel that extends through the base portion and that is in fluid communication with the body supporting portion. A fan is further included in the support cushion and is operably connect to the channel of the base portion, such that the fan is positioned and configured to move an amount of air through the channel and dissipate heat away from the body supporting portion. Methods of dissipating heat away from a support cushion are also provided.

The support cushion of claim 1, wherein the comfort layer is comprised of a visco-elastic foam. 9. The support cushion of claim 8, wherein the visco-elastic foam comprising the comfort layer has a density less than that of the visco-elastic foam comprising the body supporting layer. 10. The support cushion of claim 1, wherein each of the columnar voids are in fluid communication with the channel. 11. The support cushion of claim 1, further comprising a filter operably connected to the inlet, the outlet, or both the inlet and the outlet. 12. The support cushion of claim 1, further comprising a controller for controlling an amount of power supplied to the fan. 13. The support cushion of claim 12, wherein the controller is configured to allow power to be supplied to the fan for a predetermined time period. 14. The support cushion of claim 12, further comprising one or more temperature sensors for providing thermal feedback to the controller, the one or more temperature sensors operably connected to the body supporting layer. 15. The support cushion of claim 12, further comprising one or more pressure sensors for providing pressure feedback to the controller, the one or more pressure sensors operably connected to the body supporting layer. 16. The support cushion of claim 1, wherein the body supporting layer is dimensionally-sized to support a user lying in a supine or prone position. 17. A mattress, comprising: a body supporting layer comprised of a first flexible foam, the body supporting layer having a first surface and a second surface opposite the first surface the body supporting layer further including a plurality of columnar voids defined by the body supporting layer and extending from the first surface of the body supporting layer to the second surface of the body supporting layer;a comfort layer comprised of a second flexible foam and positioned atop the first surface of the body supporting layer;a base layer positioned adjacent to the second surface of the body supporting layer, the base layer defining a first channel and a second channel extending longitudinally through the base layer, the first channel and the second channel each having an inlet on a first exterior side surface of the base layer and an outlet on a second exterior side surface of the base layer, the first channel and second channel positioned on opposite sides of the base layer, and the first channel and the second channel each in fluid communication with the body supporting layer;a first fan operably connected to the first channel, the first fan for dissipating heat away from the body supporting layer and into the first channel of the base layer; anda second fan operably connected to the second channel, the second fan for dissipating heat away from the body supporting layer and into the second channel of the base layer. 18. The mattress of claim 17, wherein the first flexible foam is a reticulated visco-elastic foam. 19. A method of dissipating heat away from a support cushion, comprising: providing a support cushion including: a body supporting layer comprised of a first flexible foam, the body supporting layer having a first surface and a second surface opposite the first surface, the body supporting portion further including a plurality of columnar voids defined by the body supporting layer and extending from the first surface of the body supporting layer to the second surface of the body supporting layer;a comfort layer comprised of a second flexible foam and positioned atop the first surface of the body supporting layer;a base layer positioned adjacent to the body supporting layer, the base layer having a first exterior side surface and a second exterior side surface, and the base layer defining a channel extending through the base layer, the channel in fluid communication with the body supporting layer and having an inlet on the first exterior side surface and an outlet on the second exterior side surface, anda fan operably connected to the channel of the base layer; andsupplying power to the fan, such that the fan moves an amount of air through the channel and dissipates heat away from the body supporting layer and into the channel of the base layer.
