Review on Air Stability Wobble Cushion With Pump For Balance And Sensory Stimulation - 34Cm/13.5In Diameter, Ideal For Wiggle Seat And Sensory Therapy, By AppleRound by Daniel Hicks

I bought four of these to use in my classroom as wiggle seats and I'm pretty happy with them so far! They come partially inflated so I saved time pumping them up! The pumps even have an extra needle with them. I went ahead and inflated each stability cushion to four different levels to test out on chairs and did some standing exercises on them. The quality seems pretty good so far! I will definitely update this review if they do not live up to my expectations, but with the quality of these I really don't expect that to happen.I also bought 4 black seats of another brand because eventually I plan to get a class set, hopefully through a grant next time around. So far I prefer this brand due to the thickness of the material, which is a bonus because this was the cheaper brand! I don't know much about stability cushions, but when this one is inflated a lot, it still remains flattened on the surface. My other brand bubbled up to become closer to a sphere. I don't know which is preferred in the exercise world, but for my purpose I prefer the flatter shape with the thicker material (this brand).The only thing that wasn't perfect in this order was the color. I ordered black, but all four are definitely more of a charcoal gray. I don't mind at all since I'm just using them in my classroom, but I thought I would mention it.
