A cervical pillow is a specially-designed pillow meant to support the neck and head, keeping them properly aligned throughout the night. They may help with neck pains and back pains that are related to poor positioning. One of the most common designs is to have a raised section for the neck to keep it straight, followed by a pocket to cradle the head.
Cervical pillows are frequently made using memory foam or latex, although models made from other materials are available.
