SONA bicycle saddle, model SC-S-113, is a sprung bicycle seat with a plastic base and a plastic top, carried on two tension springs and three compression springs. The springs help cushion the rider over bumps and rough roads. The top is black with a lightly textured finish, a broad rounded rear and a narrower nose. Chrome coil springs sit under the rear and sides, and a metal clamp under the seat holds it to the seat post.
