A portable seat cushion comprising: A) a seat portion; B) a back portion; and C) an integral fan that circulates air through the seat and back portions, the front portion having a front surface, a perimeter, a rear surface and an interior between the rear and front surfaces and the back portion having a front surface, a top, a bottom, a perimeter, a rear surface and an interior between the rear surface and the front surface, the seat and back portions being joined by a flexible connection that permits the seat and back portions to rotate relative to each other and provides a mechanism for the passage of air from the seat portion to the back portion. The rear surfaces and perimeters of each of the seat and back portions is relatively air impermeable while the front surfaces of these members is air permeable. The interior of each of the back and seat portions includes a semi-rigid undulating member that defines passages for the movement of air from the incorporated fan to the seat and back portions and to the front surfaces of the seat and back portions through apertures therein.
