A seat cushion includes an edge portion and a three-dimensional fiber structure including core-sheath fusible fibers and skeletal fibers thermally fused at intersections thereof. The sheaths of the core-sheath fusible fibers are made of a thermoplastic elastomer to fuse the intersections and form a bulging portion at each of the fused intersections. The skeletal fibers and the cores of the core-sheath fusible fibers are made of a non-elastomer resin. The skeletal fibers are crimp-processed bulky fibers, and a fineness of the skeletal fibers and a fineness of the core-sheath fusible fibers are in a range of 1 to 200 dtex. The seat cushion has a layered structure including a plurality of layers fused together, each of the layers has the three-dimensional fiber structure, and the seat cushion has a density distribution based on regional variations of the layered structure and a stiffness distribution that depends on the density distribution.

Seat cushion having an edge portion, to be used for a seat of saddle-riding vehicle, and manufacturing method thereof

A boat includes a hull, a deck, a steering pole, and an information display. An engine is provided in the hull. The deck is mounted on an upper portion of the hull.
