An air cooled/heated seat cushion comprises: an envelope with an air inlet opening and an air discharge opening. A flexible hollow supporting padding is embedded inside the envelope to allow air to diffuse through the envelope. As air from a ventilation air source of a car, truck, or craft flows through the cushion, the cushion is cooled or heated. The cusion in turn gives a cooling or heating sensation to a person sitting on it. An even better way is to employ an air distributor inside the envelope, so that air can be uniformly distributed throughout the cushion.
