摘要：
A method of manufacturing a cushion, by impregnating a main body comprising organic synthetic fibers which are stereoscopically intertwined with a polyurethane prepolymer solution so as to allow the polyurethane prepolymer to attach the prepolymer to the fibers, subjecting the cushion body to centrifugation to remove excess solution from the cushion body, and bringing the polyurethane prepolymer attached to the fibers into contact with a curing agent comprising water so as to cure the polyurethane prepolymer.
