Water Trampolines and Water Bouncers are different! 
A water trampoline has a jump surface supported by a steel frame and trampoline springs.  A water bouncer has a jump surface supported by a spring-less intlocking webbing connected from the flotation tube to the jump surface.

A water trampoline can support heavier loads on the jump surface and will provide a higher jump than a water bouncer.   All Island Hopper water trampolines are made of 1000 denier "reinforced" PVC material and are recommended for commercial operations.  Unlike the bouncer, the water trampoline requires assembling the framed jump surface.  This will take about 30 minutes additional set-up time.

A water bouncer is a great family recreational product and costs less than a water trampoline.  It will support a good amount of weight and will provide a short bounce.  A bouncer does not require any assembly other than inflating and anchoring.
