I bought two of these one for my 4 foot 10 daughter and one for my 5 foot 4 son. They love them. They bounce around the house all of the time. They even have jousting wars with a try to knock each other off is so fun to watch. Our family has such a good time with these hopper balls I even bought the purple one for myself and I’m 5 foot 8.
