UNI FAM Exercise Stability Ball Chair, Extra Thick for Crossfit, Yoga, Balance & Core Strength Training, Slip-Resistant & Anti-Burst (Hand Pump Included)

Purchased wrong size had to return it but I’m sure if I would’ve gotten the right size just by looking at the ball out of the bag not blown up it look like he was very good material

Sturdy. Good quality. Met my needs. Fast shipping. Good value.

Its perfect!! Received exactly as described. I am using it as a chair when I am working from home. Sitting in the right posture is important as I spend too much time in front of computer.
