BERG aims to make its trampolines as safe and durable as possible. That is why each trampoline is thoroughly tested. Would you like to know how we test our trampolines? 

If so, then read on! 


Safety and quality tests

Each BERG trampoline has to endure a considerable weight in the safety and quality test. This test weight is a stationary weight which is placed on the trampoline for a considerable length of time. Visit to find out what the test weight of each trampoline is. The recommended user weight, however, is somewhat lower than the test weight. This is because the user exerts pressure on the trampoline in a slightly different way when jumping. 

BERG wants to avoid a heavier person from almost touching the ground when trampolining. That is why, based on the test weight, we also state the recommended user weight.

Stability test

We also carry out a stability test to see whether the BERG trampolines remain stable when in use. Furthermore, to make sure that the safety net around the trampolines are of good quality, we hang weights on the hoop of the safety net.


Practical tests

Before a trampoline is actually produced in the factory, a panel of children and adults extensively tests the trampoline prototype. They make the highest trampoline jumps and perform the best acrobatics. That is how we make sure the trampoline meets all safety requirements. 


Material tests

BERG carries out multiple material tests on its trampolines, for instance, chemical material tests and extensive tests to determine the strength of all used materials. A few of our tests are highlighted below.


UV test: the trampoline should not discolor

Trampolines are almost always outside and are therefore subjected to quite a lot of sunlight. The jumping mat and the green or red protective edge should not discolor through UV radiation. All jumping mats and protective edges are therefore subjected to the special UV test.  During this test, the various materials are exposed to UV radiation for long periods of time. Only when the material has not discolored is the test considered to be successful.

1.Example of a successful UV test. The safety net material has not discolored!
2.Example of an unsuccessful UV test. The safety net material has discolored too much.


Innovation and research into springs

The optimum balance between flexibility and strength of the springs is researched in special BERG spring studies. All BERG springs are elastic, flexible, and finished with a thick, rustproof layer of zinc. That is why you can keep on trampolining much longer.
