Contour Gel DoughFormed to fit the natural curves of your head, neck and shoulders, the ergonomic design of the Contour Gel Dough pillow correctly aligns the spine for comforting sleep. Infused with cooling Z gel, the Gel Dough formula creates a cooler, softer memory foam. Accompanying the pillow is a luxuriously soft rayon from bamboo velour cover, excellent for sensitive skin and temperature regulation.
