A playground apparatus is provided which consists of a base having a central ring bearing mounted onto the ground. A stanchion extends upwardly form the central ring bearing in the base, so as to rotate thereabout. An elongate balance beam is pivotally mounted near the top of the stanchion for movement up and down. A seat assembly is located at a first end of the balance beam to receive a person. A structure is located at a second end of the balance beam, for counterbalancing the weight of the person in the seat assembly. This permits the person to rotate the stanchion through a complete revolution in a clockwise and counterclockwise direction and to move the balance beam up and down.
