Formed 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.
