Abstract
The trampoline with inflated base includes a generally toroidal shaped inflatable tube having an open center area. A mesh rebound member extends over the open center area and is secured around its entire periphery to the tube on the upper surface of the tube member. The tube includes a singular air duct or a plurality of air ducts extending radially which allow communication of air between the space interior to the tube and the space exterior to the tube.
