This pillow is made from memory foam, which moulds to the bodys shape and helps to reduce tossing and turning during the night. It helps to prevent sore necks by relieving stress and tension in the neck muscles. The open spaces on the side of the pillow help to prevent wrinkles when sleeping face down, and also increase ventilation. This pillow is ideal for sports players who require straight neck posture, such as golfers, as well as those who suffer with neck pain.
