The cradle is an ancient piece of furniture, and its origins are unknown but every period of furniture style has produced a variety of cradle styles, from simple boxes to the elaborate draped state cradles of 16th-18th century Europe. The carved oak cradles mounted on rockers so popular from the 15th through the 17th century were gradually superseded in the 18th and 19th centuries by wicker cradles that were slung between end supports in order to raise them higher from the ground.
