The perfect combination of conforming memory foam and cooling gel! Memory foam surrounds a pad of Cool Gel material giving you a cooling sensation while you sleep, eliminating the need to flip the pillow to find a cool side. The Cool Gel Memory Foam Pillow responds to temperature and pressure to mold to your shape by creating the perfect support for your head, neck and shoulders. Allergy sufferers love our memory foam pillows because they are naturally hypo-allergenic. For easy cleaning, each foam pillow comes with a zip-off cover, which can be tossed directly into the washer.
