Abstract: A pillow includes an inner hollow chamber having an inlet for cool air at one end connected to a portable air conditioning unit. The chamber has thin flexible permeable walls permitting air to pass into a first surrounding layer of soft material. A non-porous air-tight lining directs the air toward one end of the first layer and around the lining through a soft outer layer toward an outlet at the opposite end. The layered construction provides uniform air distribution. Warm air from the outlet is directed both through a flexible hose to the air conditioner where it is cooled and recycled through the pillow. A detachable control unit is located adjacent to the pillow or bed. The cool pillow provides added comfort for restful sleep during hot humid weather conditions.
