A full-size comforter ranges from 78 inches by 86 inches to 86 inches by 86 inches in size. Comforter sizes correspond to bed sizes, which include twin, full, queen, king and California king. Comforters are slightly larger than bed sizes to allow for draping over the side of the bed.
Comforters are filled with materials such as down feathers, polyester batting, silk or wool. They can also be made out of fur, in which case they are backed with silk or satin. Comforters are stitched or quilted to keep the filling material evenly distributed and secured. Outer shells of comforters are usually made from silk, cotton or polyester fabrics.
