To increase the contacting degree of bedding, to prevent the shifting of the bedding by turning over in sleep and to reduce a useless space between a body and upper and lower bedclothes by attaching weights to the appropriate positions of a coverlet.

On the strong cloth 2 of an appropriate size as the coverlet capable of sufficiently wrapping shoudlers by appropriately recessing a part where the neck is in contact, many weights 1 of lead or the like of required weight are attached to the appropriate positions mainly near the edge of the cloth excluding the part to be in contact with the neck. When it is covered with a blanket or the other cloth and turned to the coverlet, since the coverlet is brought into close contact with a mattress by the weights 1, the fear of shifting and falling is eliminated at all. Since a useless air amount between the body and the bedding becomes less, warming is quickly performed. Since the shoulders are covered well, even when turning over in the sleep is performed, the air goes out and comes in less, the fear of getting cold is eliminated and sound sleep can be performed. Since the weights 1 are not brought into direct contact with the body, the fear of getting heavy is not present.
