PROBLEM TO BE SOLVED: To provide an excellent fiber molded wadding which has good flexibility, avoids splitting among single fibers, and has good resistance to permanent set, appropriate surface softness, and core hardness and elasticity in a well- balanced fashion. SOLUTION: A fiber molded wadding having a flexibility of 3 cm or more comprises a plurality of sheet layers which are independent of one another without being coupled together, one of the sheet layers being a fiber sheet layer in which single fibers are almost three-dimensionally aligned with respect to a plane, with such single fibers partly bonded or coupled together. The other sheet layers are each made of at least one kind of sheet layers selected from a fiber sheet layer in which single fibers are aligned almost parallel to the plane and an urethane foam sheet layer, with the entire wadding wrapped in cloth 4. |
