ABSTRACT:
A seat structure includes a seat frame, a three-dimensional net stretched over the seat frame, a skin material for selectively covering the three-dimensional net, and a fastener for connecting a portion of the skin material and the three-dimensional net. The fastener is selectively opened or closed to change a surface rigidity of the seat structure.
