A 12-ft inflatable water trampoline that floats on a lake or pond, with a 96.5-in bounce area big enough for one adult or two children at once. Bungee cords replace steel springs, so the deck stays springy in the water without parts that corrode. The package covers a full setup: an electric inflator that fills the bouncer in about 10 minutes, a rope ladder, three mooring lines, and an anchor to stop it drifting. Elastic nylon over heavy-duty PVC handles sun and repeated boarding. Use only in calm water deeper than 6.5 ft, by riders 14 years and older.
