The round trampolines of Acon are a great choice for everybody, they provide a great bounce with top of the market durability. The highest bounces are achieved in the center of a round trampoline, because with a round trampoline all the springs work simultaneously and tend to draw jumpers back to the center. This is also a great safety feature, especially for younger children.
Acon's rectangular trampoline, the 16 Sport HD however is a great choice when you are looking for something more. It is the right choice for true hardcore use, be it training for sport (parkour, gymnastics, tricking, etc.). It provides unparalleled bounce, safety and longevity in tough use. Due to the rectangular shape you can bounce equally high no matter where your jump is located on the trampoline mat. This is a big difference between a rectangular and a round trampoline - with the rectangular trampoline the springs work separately depending where your jump is located.
