A pillow is a support for the head or other parts of the body, used while sleeping on a bed, or, in the United States, for the body as used on a couch or chair (which British English would call a cushion).In contemporary western culture pillows consist of a fabric envelope which contains a soft stuffing, which may range from down feathers to synthetic foam. In other cultures, pillows have been made of wood or stone. Bed pillows are typically covered with a cloth pillowcase.
