ABSTRACT:
Hollow polyester fibers are blended with sheath/core binder fibers and bonded together in a ratio of 80 to 18 to form a support cushion. Several layers may be laminated together. The denier of the polyester fibers in at least some of the layers may vary from the denier of the polyester fibers in other layers. For this purpose, the deniers of the polyester in the various layers are selected from the range including 4 to 40. The polyester in at least some layers, perferably the outermost layers, are slickened. In an alternative approach, there is provided a wrapping of the outermost layers formed of unbonded polyester fibers.
