'penepico Large Sensory Massage Balls for Kids, 33.5'' 85CM Bouncy Exercise Ball, Big Inflatable Ball with Tactile Spikes, Outdoor Ball Pool Ball Yoga Ball, Large Beach Ball'

I ordered 85cm, it looks huge, I am very happy my daughter loves it. She sits on it to read books, leans on it when watching iPad. It holds air pretty well, material is tough.

My son has atuism and he loves it

My 2-year old grandson likes this ball a lot. It’s great for a larger outside space. I questioned if the bumpy surface would be an issue but realized that it actually makes it easier for a young kid to grab & roll. It was fun at an outdoor party with young kids.

You have to pump the ball up by hand or foot, there is no other option, made well, comes with instructions, make sure to read if not could get frustrating, my 5 year old autistic son loves it

Not sure, but I think mine had been returned by someone. It didn't come with any directions and the ball, small pieces and pump meant to blow it up came all loose l in one big bag. We dropped the "needle" while trying to figure it out and one of the puppies instantly grabbed it and chewed it up. *heavy sigh* I will try a SS needle and see if that works. The ball itself seems to be well made, is heavy duty, and will probably last a few days (I don't expect ANY air-filled ball to last long with these little border collie hellhounds! LOL). It's just a matter of figuring out how to blow it up now that the parts have been destroyed. If I ever get it blown up, I'll post photos.
