1. A support cushion, comprising:
- a body supporting layer comprised of a first flexible foam and 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 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; and
a fan operably connected to the channel of the base layer, the fan for dissipating heat away from the body supporting layer and into the channel of the base layer.

Abstract
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.

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, and a fan operably connected to the channel of the base layer; and supplying 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.
