<P>PROBLEM TO BE SOLVED: To provide a cushioning structure that is compressed with soft feeling in use, has so high air permeability that a user minimally becomes sweaty during use, is easy to handle to be folded for storage or bent, and has high durability, and to provide bedding including the cushioning structure. <P>SOLUTION: A fiber structure includes: nonelastic crimped staple fibers; and thermoadhesive conjugated staple fibers including a polymer that has a melting point lower by 40°C or more than that of a polymer included in the nonelastic crimped staple fiber and is disposed as a thermally adhesive component on a surface thereof, and these fibers are blended to attain a weight ratio of 90/10 to 10/90, adhesion points where the thermoadhesive conjugated staple fibers crossing each other are thermally adhered and/or adhesion points where the thermoadhesive conjugated staple fibers and the nonelastic crimped staple fibers crossing each other are thermally adhered are scattered and the thermoadhesive conjugated staple fibers and the nonelastic crimped staple fibers are arranged in a thickness direction in the fiber structure. The fiber structure is subjected to profile processing or the like so as to form convex portions over the whole surface of the fiber structure, whereby obtaining a cushioning structure. <P>COPYRIGHT: (C)2013,JPO&INPIT |
