The comforter can trace its origin to the quilt. The quilt, in turn, can trace its origins nearly to the beginning of mankind's history when man sought to cover himself with animal skins so as to keep warm. When people learned about fibres, these coverings started being made of loosely-quilted linen and other fabrics. The present-day comforter is stuffed with poly batting, silk, feathers, cotton, and other materials. Be careful when buying a cheap comforter set.
