A flotation trampoline adapted for use on a body of water comprising a non-elastic, collapsable encasement having a symmetrical configuration. The base cover is attached to a perimeter on the lower, interior tube surface and is adapted to seal off a rapid air or water flow through the tube opening to thereby create a substantially closed volume between the base cover, lower interior tube surface and the water surface upon which the tube is placed. A resilient cover is attached at the top of the encasement to provide a trampoline spring mat.
