Lifespan HyperJump 3 vs Kahuna Classic
Both of these are budget round trampolines, and they differ in what holds the mat and the length of the frame warranty.
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 comes with a 10-year frame warranty against 1 year from Kahuna, which is a large difference at this price. Kahuna provides 1-year mat and net warranties; the HyperJump 3 provides a 1-year mat warranty and publishes no net warranty.
Kahuna is cheaper at most sizes, goes to 16 ft where the HyperJump 3 stops at 14 ft, and is rated to 150 kg per jumper at its largest against 140 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.
