Lifespan HyperJump 3 vs HyperJump 4

These are Lifespan Kids' two main round trampolines, and they differ in the one place that matters most: what holds the mat.

The HyperJump 3 is springless, using elastic straps instead of steel springs. The HyperJump 4 uses conventional coil springs. Both carry a 10-year frame warranty and both are rated to between 100 and 140 kg per jumper depending on size.

Which model meets the standard runs against expectations here. The coil-spring HyperJump 4 is listed as meeting the Australian Trampoline Standard AS 4989:2015; the springless HyperJump 3 is not. If you are shopping for a springless mat specifically because of safety, that is worth knowing before you decide.

The HyperJump 4 also comes with a 2-year mat warranty against 1 year on the HyperJump 3, and is available in a 16 ft size. The HyperJump 3 covers 8 ft to 14 ft and is usually cheaper.

Choose the HyperJump 3 if you want a springless mat at the lower price. Choose the HyperJump 4 if meeting the standard, a longer mat warranty or the 16 ft size matters more.

Quick verdict

The HyperJump 4 meets the standard and has the longer mat warranty. Choose the HyperJump 3 if you want a springless design, with the caveat that it is not the model that meets the standard in this range.
