Good quality baseballs and softballs are made completely differently.

Inexpensive softballs are made of a cork and rubber mixture and a vinyl or other synthetic cover, then stitched with yarn.

The vast majority of softballs, both slowpitch and fastpitch, are made of a solid polyurethane core and a leather cover stitched with nylon thread. The cover on better softballs is glued to the core before stitching. A fastpitch softball has raised seams and a slowpitch softball has flat seams.

The core is the ball itself, not to be confused with COR, which stands for Coefficient of Restitution. Softballs are measure by two variables - COR and Compression. The higher of either number the harder the ball.

The compression is simply the pounds per square inch required to compress the ball 1/4". The COR is the speed in which the ball goes from the compressed state back to its original round state (rebound).

Yes, the core of a softball does bounce. It is made out of cork. This is what makes the softball bounce.

The inside of a softball is made of cork. Even though it is called a softball, it is not soft at all. Take it from me :)
