Abstract: A comforter to be used when sleeping made by joining a front cover cloth and a back cover cloth by sewing their edges together. The inside of the comforter is divided into a plurality of spaces by crosswise parting members and lengthwise parting members, the height of each of the crosswise parting members becoming lower toward both ends, and each space is filled with down which is soft, fine feathers, etc. Because of the parting members, the down does not move around inside the comforter, and always follow the posture of the person using it, thus snugly covering their body.
