Abstract
In one example, a teeter totter is provided that includes four support arms spaced apart at substantially equal angular intervals, with a seat being attached to each of the support arms. A hub of the teeter totter includes top and bottom plates which cooperate to at least partly define four sockets, and each of the sockets receives an end of a corresponding support arm. A plastic receiver is connected to the hub, and a plastic pivot is rotatably engaged with the receiver such that the pivot and the receiver cooperate to enable simultaneous movement of the seats in three dimensions. Finally, a base is provided that supports the pivot.
