Since the 1920s, when the pogo stick first appeared, kids of all ages have tried to master the skill and balance necessary to bounce. The Jumparoo Boing! is available in three sizes so siblings and friends of different heights and ages can all experience the action. The Large holds 90-160 lbs. After a little bit of practice, kids can get the Jumparoo Boing! bouncing up to 2 feet high! Colours may vary.
