Water trampolines typically have a larger surface area and are supported by springs or inflatable tubes, providing more bounce and stability. On the other hand, water bouncers are smaller, simpler inflatable structures without springs, offering less bounce and stability but are easier to set up and more portable.

There is a common misconception that a water trampoline is the same as a water bouncer. However, there are significant differences both in construction and performance. Water trampolines, just like their land-based cousins, have springs that connect the jump surface to the supporting trampoline structure.
