Abstract: A cushion paper assembly for a toilet seat includes a base, and a stack of cushion paper and a double-coated adhesive tape respectively adhered to a top and a bottom of the base. The stack of cushion paper is adhered to three folded edges of the base extending upwards. The double-coated adhesive tape is adhered to the toilet seat when the assembly is used. When the toilet seat is lifted up, the cushion paper assembly is clipped between a toilet seat cover and the toilet seat. When the assembly is to be used, the toilet seat is lowered down, and the used cushion paper is torn off to expose the next sanitary and unused cushion paper. Thus, it is possible to prevent the hip and the legs from being infected by skin germs, and the cushion paper assembly for the toilet seat can be used in a sanitary and convenient manner.
