Review on Blue AppleRound Air Stability Wobble Cushion With Pump - 34Cm /13.5In Diameter - Ideal For Balance, Sensory Stimulation And Active Sitting by Jeremy Bradford

I just recently learned about this so thought I'd try it. I was still a bit skeptical, but when it arrived I was positively surprised. It seems quite sturdy, and we used the pump and we all tested it out. It's fun to stand on, and always realized a 7 yr old is way more balanced than us adults. We did buy it for him to use on his chair for doing some of his reading/schoolwork. He even uses it to sit on the floor. He loves it, and likes to sit on it and stand on it, and when he's upset, he likes to bounce on it.So, I'm sure we will get our use out of it. Can't speak for longevity as we did just get it. Pump and needles work great, and it is easy to fill up. Also easy to deflate.
