Review on WALIKI Hippity Hop Therapy Ball For Kids - Blue, Ages 7-9 (20"/50CM) by Frank Chinchilla

Nice ball, back side shows elephant's "behind" and my kids laughed at that, this one is a good size for my 70th percentile height/weight 4 year old, anything bigger is really too big (he gets on 9 year old's bigger one and can do it but doesn't have good control) We use these inside to get out energy when going outside isn't an option. Make sure you have a pump though, you have to pump it up and will have to refill it at points over the course of owning them (having had kids on these for 8 years we know eventually they all need refills!)
