1. When choosing a trampoline, you should first choose a big brand and don't covet cheap brands, because the stability of brands is not good. Secondly, it is very important to pay attention to whether the purchased trampoline has passed the safety inspection certification, which directly reflects the safety of trampoline.

2. The structure of trampoline looks very simple: a set of metal brackets, and then the "bed surface" and "bedstead" are connected by springs, and a trampoline is born. In the domestic trampoline, the smaller diameter is only about 1 m (taking the circular trampoline as an example), and the jumping area is correspondingly smaller. If you need a larger jumping area, you can choose a square or rectangular trampoline.

The size of trampoline is also one of the factors to be considered. If you use a trampoline at home, you need to choose a trampoline that suits your family space. If you use a trampoline in the gym, you need to choose a suitable trampoline according to the size and space of the gym.
