mattress

n. large rectangular pad made of soft or springy material that is placed on a bedframe or on the floor to sleep on, pad filled with air or water for sleeping on

A mattress is a mat or pad, usually placed atop a bed, upon which to sleep or lie. The word mattress is derived from Arabic words meaning "to throw" and "place where something is thrown" or "mat, cushion." During the Crusades, Europeans adopted the Arabic method of sleeping on cushions thrown on the floor, and the word materas eventually descended into Middle English through the Romance languages.
