Trampoline FAQs


You need a clearance of at least 8 metres above and 2 metres around the trampoline regardless of its size. Before use, make sure to remove loose items or toys around the trampoline’s perimeter. You must also keep the space under the trampoline free from obstructions. 

Check out our Trampoline Placement Guide for more information on safe trampoline setup.

Kahuna offers a wide range of trampolines for sale. 

When choosing a trampoline size, consider the following factors: 

  • The size of your yard — remember that you need a 2-metre clearance all around the trampoline. 
  • The age, height and weight of the users — check the trampoline’s weight capacity (found in the listing specifications) to make sure that it can support each user. 

Visit our Trampoline Size Guide for more information. 

Children 6 years old and above can jump on a full-sized trampoline (6ft and bigger). For children aged 3–5, we recommend purchasing a toddler trampoline such as the Kahuna Mini. 

Adult supervision is required at all times when the trampoline is in use.

Trampolines must be installed and used on a shock-absorbent, level surface, e.g. lawn or bark.

Do not install or use your trampoline on stones, gravel, crushed rock, sand, uneven grass, uneven concrete or any loose surface. 

Make sure that the area above and around your trampoline is free from potential hazards. These include walls, fences, trees and other toys or equipment.

Most trampolines can be assembled at home by two adults with no special tools needed. 

Before assembly, check that you have all the parts (listed in the manual), and wear closed shoes for safety.

Conventional trampolines get their bounce from the coil springs that connect the mat to the frame. A safe, well-designed trampoline should have thick padding over the springs to prevent any potential injuries. Classic and bouncy, these are the trampolines of choice for most Australian families. 

Springless trampolines, on the other hand, use elastic straps or rods instead of conventional springs. This results in a gentler bounce that is easy on the knees. Rebound systems vary between different models, so check with the manufacturer to confirm how the product works. 

Read more in our Spring vs. Springless Trampolines guide.

Only one user should be on the trampoline at a time. Jumping with others can lead to collisions and injury, especially in young children. An adult should always be present to enforce safe trampoline use.

Do not:

  • jump with pets or other users.
  • allow more than one child on the trampoline at a time.
  • attempt somersaults without proper training.
  • use the trampoline when the jumping mat is wet.
  • use the trampoline when there are loose items around or under it.
  • use the trampoline without its safety enclosure and padding.
  • jump from the entrance to the ground. Always use a trampoline ladder.
  • use the trampoline as a springboard to other objects.

Make sure to follow trampoline safety rules at all times.
