A comforter is a type of bedding— a soft flat bag used on a bed as a type of bed cover. It is filled with either an artificial material (such as polyester batting) or a natural material. A comforter usually doesn't cover the pillows or box spring of the bed. Its purpose is primarily decorative, since comforters don't provide much warmth, unlike blankets whose purpose is to provide warmth. A similar type covering made from feathers (often including down) is generally referred to as a duvet. See also: Silk comforter Search Term: "Comforter" Categories: Bedding | Linens
