A pillow is a support of the body at rest for comfort, therapy, or decoration. Pillows are used in different variations by many species, including humans. Some types of pillows include throw pillows, body pillows, decorative pillows, and many more. Pillows that aid sleeping are a form of bedding that supports the head and neck. Other types of pillows are designed to support the body when lying down or sitting. There are also pillows that consider human body shape for increased comfort during sleep. Decorative pillows used on beds, couches or chairs are sometimes referred to as cushions.The earliest recorded use of the modern human device dates back to the civilizations of Mesopotamia around 7,000 BC During this time, only the wealthy used pillows. The number of pillows symbolized status so the more pillows one owned the more affluence they held. Pillows have long been produced around the world in order to help solve the reoccurring problem of neck, back, and shoulder pain while sleeping. Besides for comfort, the pillow was also used for keeping bugs and insects out of people's hair, mouth, nose, and ears while sleeping
