Lifespan HyperJump 3 vs Kahuna Classic
This page contains affiliate links and we may earn a commission on purchases.
Both of these are budget round trampolines, and they differ in what holds the mat and how much component warranty detail is published.
The HyperJump 3 is springless, using elastic straps rather than steel springs, which removes the exposed spring beside the jumper. The Kahuna Classic uses conventional coil springs under padding. Neither is listed as meeting the Australian Trampoline Standard AS 4989:2015.
The HyperJump 3 publishes a 10-year frame warranty and 1-year mat and net warranties. Kahuna lists a general one-year Australian warranty but does not break out separate frame, mat and net terms.
Kahuna is cheaper at most sizes, goes to 16 ft where the HyperJump 3 stops at 12 ft, and is rated to 150 kg per jumper at its largest against 125 kg.
Choose the Lifespan HyperJump 3 if you want a springless mat and a 10-year frame warranty. Choose the Kahuna Classic if you want the largest possible trampoline for the least money.

The HyperJump 3 offers clearly published long frame coverage and a springless design for a modest step up in price. Kahuna wins on size at the top of its range and on outright price, but only a general warranty term is recorded.
