The Z Shoulder ZONED DOUGH Memory Foam Pillow with Gel brings you the benefits of memory foam pressure point relief, combined with a cooler sleep environment, plus the unique shoulder recess designed for side sleepers. Gel-infused memory foam sleeps cooler than regular memory foam thanks to gel beads that pull excess heat from the body. There are two comfort zones in this pillow. The center of the pillow has larger holes to provide optimal comfort for your head, while the outer edging of the pillow uses smaller holes to support your neck and correctly align your spine. Our memory foam is Certipur-US certified and free of harsh chemicals. The TENCEL cover is removable for laundering, helping you to create a healthy sleep environment. This pillow is also backed by a 5-year U. S. .
