Abstract
An elongated unitary inflatable vessel of thin, flexible sheet material includes a pair of relatively large volume, generally circular-shaped, hollow seats at opposite ends interconnected by an integrally formed central conduit of relatively smaller transverse cross-section. Each seat includes an upper seating surface for supporting a person in an elevated position above the floor and the person on one seat may force the seating surface downwardly toward the floor thereby moving air from the seat into the conduit to raise the elevation of the opposite seat and provide a seesaw action.
