Abstract: A balance platform accessory for use with other balance platform elements or other elements to form a balance platform. The accessory is rigid and board-like, with a flat first surface and a flat or concave second surface. It is configured to rock on an other object such as: an object with a convex upper surface and a flat lower surface, a ball-like object of suitable size, or a cylindrical roller type object. The curvature of the second surface affects the difficulty of balancing using the object and the other element. Multiples of this balance platform accessory may be used as a set, allowing a user to select which accessory will produce the difficulty of balancing that they desire.

Abstract: A balance platform configurable to have a second member with a flat side on the ground and a curved side facing upwards, and a first member that rocks on the second member. The elements of this balance platform are interchangeable in position to create different parameters of movement based on the different configurations. This invention may be used as a very easy balance platform for work or when upper body stability is desired. Additionally, there are different curvatures and combinations of curvatures of the surfaces that may be combined to adjust difficulty of balancing.
