Improved foam seat cushions that are ergonomically shaped, equipped with a notch to facilitate proper sitting and to potentially center on a seat, and a plurality of channels running through the cushion to provide cooling. In some examples, the foam seat cushion includes handles located on either side and can be folded in half for easy transport. In some further examples, the foam seat cushion includes a cushioning layer disposed at the foam layer.

1. A seat cushion, comprising: an ergonomically shaped layer; anda cushioning layer disposed atop the ergonomically shaped layer, wherein: the shaped layer and cushioning layer have a plurality of channels disposed across their surface that extend from the top of the cushioning layer through the bottom of the shaped layer,the shaped layer and cushioning layer have a notch that partially bisects the shaped layer and cushioning layer, thereby forming a channel that extends from the top of the cushioning layer through the bottom of the shaped layer, andthe ergonomically shaped layer has at least one handle disposed upon it; andan air and moisture permeable, removable, form-fitting cover containing at least one compartment for enclosing the shaped layer and cushioning layer wherein the form-fitting cover contains a hole positioned so as to allow access to said handle. 2. The seat cushion of claim 1, wherein the ergonomically shaped layer further comprises two handles, with each handle affixed to opposing sides of the ergonomically shaped layer, and the form-fitting cover contains a second hole, each hole positioned to allow access to said two handles. 3. The seat cushion of claim 2, wherein the ergonomically shaped layer is at least partially bisected along an axis defined by the notch, and the opposing sides are substantially parallel to the axis. 4. A foam seat cushion, comprising: a foam layer, possessing a top surface, a bottom surface, a first side, a second side, a third side opposing the second side, and a side opposing the first side that is scalloped in shape;a cushioning layer disposed upon the top surface of the foam layer;a notch disposed approximately in the middle of the first side, running between the cushioning layer, the top surface and bottom surface of the foam layer, and extending towards the center of the foam layer so as to partially bisect the foam layer;a plurality of channels passing through the foam layer and cushioning layer, with openings on the cushioning layer, top surface and bottom surface;a first handle attached to the second side;a second handle attached to the third side; andan air and moisture permeable, removable, form-fitting cover containing at least one compartment for enclosing the foam layer and cushioning layers;wherein: the form-fitting cover contains a first hole and second hole, each positioned so as to allow access to the first handle and second handle, respectively; andthe foam layer and cushioning layer are at least partially bisected along an axis that is defined by the notch, and extends from the notch to the center of the first front side that is scalloped in shape. 5. The foam seat cushion of claim 4, wherein the plurality of channels are distributed in a plurality of zones, each one of the plurality of zones being located adjacent to one of the second or third sides, so as to leave a central portion of the foam layer without channels. 6. The foam seat cushion of claim 4, wherein the plurality of channels are located in an area approximately in a center third portion of the foam layer, proximate to the notch. 7. The foam seat cushion of claim 4, wherein the foam layer is constructed of viscoelastic urethane foam. 8. The foam seat cushion of claim 7, wherein the cushioning layer is comprised of a gel-filled layer, and the plurality of channels extend through the cushioning layer. 9. The foam seat cushion of claim 4, wherein the foam layer and cushioning layer are fully bisected such that the foam layer and cushioning layer each have individual halves. 10. The foam seat cushion of claim 9, wherein the form-fitting cover that encloses the foam layer and the cushioning layer contains two compartments, where each compartment encloses each individual half of the fully bisected foam layer and cushioning layer, wherein the form-fitting cover keeps each individual half of the fully bisected foam layer and cushioning layer together. 11. The foam seat cushion of claim 4, wherein the top surface is ergonomically contoured. 12. The seat cushion of claim 1, wherein the notch meets the top of the cushioning layer at an angle between approximately 25 to 45 degrees. 13. The seat cushion of claim 1, wherein the plurality of channels are located in an area approximately in a center third portion of the shaped layer, proximate to the notch. 14. The seat cushion of claim 1, wherein the plurality of channels are distributed approximately evenly over the shaped layer. 15. The seat cushion of claim 14, wherein the cushioning layer is comprised of a gel-filled layer, and the plurality of channels extend through the cushioning layer. 16. The seat cushion of claim 1, wherein the shaped layer is constructed of viscoelastic urethane foam.
