PROBLEM TO BE SOLVED: To solve the problem that bedding or a sofa can not directly cool or warm a user's body because they do not have the function of cooling in summer or warming in winter like a floor. SOLUTION: A bag body at least the inside of which exhibits thermocompression bondability is filled with a liquid latent heat storage material. Further, the heat storage material is divided by thermocompression bonding both sides of the bag body in a lattice shape. In this manner, independent small-volume cushion pieces containing heat storage materials are formed and several of the cushion pieces are coupled. COPYRIGHT: (C)2009,JPO&INPIT
