Trideer Exercise Balls Physical Therapy, 9 Inch Pilates Ball Between Knees for Physical Therapy, Mini Exercise Ball - Yoga Ball, Small Workout Balls for Core Strength and Back Support

This ball really does stay in place while using it for PT exercises. It's also nice and soft, yet strong enough to use daily.Filling with air is better than other exercise balls I've used in the past.

So happy I ordered this. I was looking for something to help with physical therapy exercises and this one works perfect. It’s flexible and quality is really good for the price. I like that it comes with instructions that explain easy way to air up and deflate when not in use! Texture is smooth and seems to be durable. Easy to grip and the size fits the purpose.

Great yoga ball. I have used it several times while rehabbing both a back and leg injury. I like the size of it. Not too big, not too small. Holds air for a long time. I have had it for going on three years and have only refilled it twice.

this has been great for doing my body weight workout. Had a little trouble holding the inflation, but overall, Gary please

Easy to use pump, he ball is soft and durable. It has helped me with my back pain.

Update to my original review. The company contacted me and promptly sent a new ball. This ball I was able to inflate and it has stayed inflated. Great customer service. Thank you.My exercise ball does not retain air. The first time I inflated it, I slightly under inflated so I didn’t overstretch. The next morning it was all wrinkled and lost inflation. The second time I inflated to normal size. By the second day it was flat again. I tried one more time as the air is getting colder in house but still the same result. Unfortunately it is past the refund period.

Perfect. My 90 year old aunt uses it for pelvic floor exercises and loves it

Perfect Pilates ball for home use. Love the ease of inflation as well. Highly recommend
