Round Trampolines are great for outdoor family use. They support more then one bouncer at a time with the larger Round trampolines able to take up to 3 people bouncing at once.
They tend to be safer then trampolines of other shapes as the trampoline tends to give a more controlled bounce and has the effect of pushing bouncers back towards the center of the trampoline bed.
They are therefore more suitable for recreational purposes and children.
