Your head lies on a pillow that offers more neck and shoulder support. The material shifts as you move. It is always comfortable, no matter what position you take. You probably have your head on a memory foam pillow. Memory foam pillows are made of material developed by NASA. It is able to distribute pressure across the entire surface.

Memory foam pillows are usually denser than regular foam pillows and are usually heavier. They are also more expensive. But they are the best pillows for those who have head and neck problems. The memory foam will heat up as the head and neck comes into contact and it will mold itself into shape. This brings about a wonderful sleeping environment which provides the proper support to the head, neck and shoulders.
