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.
It is instead called a quilt, duvet or an eiderdown. A duvet differs in that it is thicker and usually used without blankets or extra sheets. Sometimes a comforter is sold as a bed in a bag. This term usually denotes an entire set of bedding, including either a comforter or duvet with its cover. Comforters are sometimes packaged in a set that also includes a bed skirt, pillow shams, and sometimes pillows.
