Abstract
A seat includes a seat frame having a steel spring, and a cushion pad of soft polyurethane molded foam placed on the steel spring. A stretchable nonwoven fabric, having an elongation after fracture of at least 180%, is integrally formed in a laminated manner at a portion of the cushion pad in contact with the steel spring thereby providing enhanced comfort while inhibiting wear or breakage of the cushion pad due to the steel spring acting thereupon.
