What is a comforter?
A comforter is used on top of a bed and is meant to be slept under. Depending on your preference, it is sometimes placed on top of the sheets, sometimes used without a top sheet, and can be used with or without a blanket. Comforters should drape over the sides of a mattress a few inches. A comforter is basically a large bed cover made with two pieces of fabric stitched along all four sides and filled with insulating material. CampusBedding.com offers both a down comforter (filled with natural down) and a down alternative comforter (filled with a synthetic micro fiber).
