This gym ball is what you'd expect for the cost. The ball seems to be smaller than other balls described as the same size.

My wife used this ball for lower back rehabilitation. It received heavy use for two months and held up well. Very good quality for the price.

This ball measures 19" in diameter when inflated. I next purchased the 30" blue anti-burst ball and it measures 22" when inflated. So if you want a 22" ball go with the blue 30". I don't know what tall people should order, I am only 5' 2". These are quality balls and are fun to sit on and exercise with. I expect they will last a long time.

No overpowering odor like some gym balls. The only reason I didn't give it 5 stars is that it was a bit hard to inflate completely.

the exercise ball was exactly what I expected. thank you overstock.
