A filling material of polyester fibers is formed by garnetting staple length fibers to a web then spraying a resinous bonding agent on the web and curing the resin to bond the constituent fibers. The resin is present in diminishing quantities through the web from one face to the other. A plurality of such webs may be used to form a layered structure which has a high degree of filling support weight along with a desirable degree of softness. |
