Memory foam is a blend of polyurethane (a polymer made as a byproduct of petroleum refining) and additional chemicals that give the memory foam its low-resilience. It was originally developed by NASA in the 1970s for airplane cushioning and has since become one of the widest materials used in mattresses and pillows.

You may feel better and sleep better with a neck pillow. It's sometimes called a cervical pillow because the upper part of your backbone (where your neck is) is called the cervical spine. Research suggests that a pillow with good cervical support can help relieve neck pain and improve rest.
