ABSTRACT:
In a cushion which uses synthetic cotton formed of curled polyester fibers, the synthetic cotton is a mixture of first and second fibers having two different thicknesses. The fibers are three-dimensionally intertwined with air-passing space. The first fibers have the denier value of 20 or more, while the second fibers have the denier value of less than 20. The first and second fibers are mixed in the ratio of 0.5 to 2:1 by weight. These fibers of the synthetic cotton are bound at their intersections by means of a polyurethane binder such that the air-passing space is maintained.
