Review on AppleRound Jr. Sensory Wiggle Seat With Pump, 31Cm/12In Diameter - Inflatable Cushion For Kids by Roberto Strumer

My son is a proprioceptive seeker and loves sitting on this during every meal, and it is exactly the right size to top our kitchen stools. Frankly, I feel sick when I sit on it, I can't take it for even a whole minute. I must be an avoider. I'm not sure if it's helped his prop all the way around, but somehow mealtimes are a bit calmer. It's basically a little pillow, you can control firmness by how much air you put in there. They give you the needle and the pump. Esp for the price: highly recommend.
