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.
Warranty detail is where they separate. 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. Check the component rows against the exact model you want.
No model from either brand is listed as meeting the Australian Trampoline Standard AS 4989:2015. If that standard is a requirement, this is not the right pair to choose between.
Choose Lifespan Kids if you want a springless mat with a published 10-year frame warranty. Choose Kahuna if you want the broadest choice of low-priced sizes and shapes.
