ABSTRACT:
A toy device comprising an exercising teeter board mounted for rotation on and for movement with a rolling base. The board and its base are especially configured so that portions of one nests within the other so as to preclude a lateral or longitudinal shifting motion of one relative the other. This design lends significant safety features in that it permits persons riding the respective ends of the board, whether standing or sitting, to tilt the board and induce its longitudinal back and forth movement with its rolling base without fear of being thrown from the board due to a twisting or a longitudinal or lateral shifting movement of the board with reference to its base.
