Kahuna vs Lifespan Kids
This page contains affiliate links and we may earn a commission on purchases.
Both brands sit at the budget end and offer both sprung and springless choices. Kahuna is mostly coil-sprung across round, oval and rectangular shapes, with the elastic-band Twister Springless. Lifespan Kids sells the springless HyperJump 3, which also uses elastic straps instead of steel springs, alongside conventional coil-spring models.
The main difference is warranty detail. Lifespan Kids provides a 10-year frame warranty on the HyperJump 3 and 5 years on the other current models. Kahuna lists a general one-year Australian warranty but does not break out separate frame, mat and net terms.
No model from either brand is listed as meeting the Australian Trampoline Standard AS 4989:2015.
