Making the world better, one answer at a time. The word foil in drama means a character or scene that is set up as a contrast to another so that each will stand out vividly.. Hope that helped.
Typically, a comforter is a thick, quilted, fluffy blanket that is used to keep you warm. It is usually filled with synthetic fiber filler which is quilted or stitched to secure the filling and keep it evenly distributed. Unlike a duvet, the comforter only forms one piece of all of your bed linens.
A bedspread can be a quilt or a comforter & visa versa, but not always. It is any textile used as the outside layer on a bed (except for a small throw). They typically cover more of the bed than a typical blanket, quilt or comforter. Duvet & duvet cover definitions are fine.
