The Balance Fun Set is a balance training device designed for use with children with balance, neurological, or mobility disabilities. The set is made up of four separate pieces of a full circle, all of which can be used individually for multiple activities, or together as a single unit. The interchangeable set can be used to rock, roll, balance, or climb. The front, back, and sides of the pieces all provide different surfaces and ideas for play. The pieces may be place on their sides to create a balance beam.
