Customer Review: Not quite right
My husband bought this ball to sit on at his desk to help with posture. Unfortunately at 6 feet tall and 175 lbs the ball wasn’t tall enough. On the bright side our 3 year old was able to pump it all the way up. We did use the measuring strip that came with it to ensure it had proper inflation. Prior research indicated a 65 cm ball would be adequate. Apparently a 75 cm ball would have been a better choice.
