The 8x12ft In-Ground trampoline is suitable for all ages, ideal for 6-14 year olds and young gymnasts.

This trampoline has the best bounce of any 8x12ft we have ever tested and kids will love the bounce provided by our unique engineered frame design, keeping them outside and active for longer and providing safe and reliable fun that will keep your whole family fit and healthy.
Note: More experienced gymnasts commonly prefer the 9x14ft or 10x17ft trampolines due to the extra length to round out extended flips.

Exceeds Australian Standards

All of our trampolines are designed for safety and built to last. Australia Standards AS 4989:2015 are one of the toughest set of standards for trampolines in the world. We have done countless hours of research and development to ensure our trampolines not just meet, but exceed these standards.

Note: These Australian Standards are not mandatory so before purchasing elsewhere ensure the trampoline meets AS 4989:2015

Green Tick
Mat - UV Resistant Material

The trampoline mat material is sourced from Tencate™ Permatron®, (Tencate is a USA based company). This is the most durable & UV resistant trampoline mat material available, all backed by our three-year warranty.

NOTE: Our spare parts will come with either a White Cross or the GeeTramp logo in the middle of the mat. Contact us if you have a strong preference for either one, as we can check which is currently available.

Trampoline Mat Close Up
Padding - one of the Safest in New Zealand

These pads are carefully hand-made and designed from the ground up with safety, durability, and long life in mind. Our pads feature a unique two-step foam that puts protection where you need it the most, (over the frame), also making it very water resistant - the water just runs off the pads and prevents excessive pooling.

See what makes our pads so safe.

Frame - Engineered for Strength & Extra Bounce

Our unique frame design is what gives our rectangle trampolines the extra bounce everyone desires. The long side of our frames curve out, this works with the springs to give users a nice, smooth & responsive bounce.

Who installs in ground trampolines?

  • Local landscaper
  • Handyman

Things to think about

  • Local government requirements
  • Soil type
  • Retaining wall
  • Drainage
  • Getting the hole and retaining wall sizes right

Note: We do not install in ground trampolines.

Note: The trampoline frame sizes listed on our website are for naming the generic size of a trampoline and should be treated as a ballpark reference only, these nominal sizes should not be relied upon when digging the actual hole or for making the retaining wall. For our rectangle range, the long side frame rail has a curve by design which needs to be factored in. Depending on the installation method you choose, you may also need to allow for an air flow gap.
When sizing up to make the hole or retaining wall it is strongly suggested you already have the trampoline with the mat and springs assembled so you can then directly measure off the actual assembled product dimensions.
