Kids blue bouncing learning chair LIKE NEW!!

Blue kids bouncing ball to help those of us that cant sit still well esp in a learning environment. It is perfect from prob ages 4 to 12. Depending on weight ofcourse. I weigh 111 and can sit on it fine. I think 150 or 200 lbs may be pushing it.I tried measuring around the Ball blown up and it was around 54 inches. Ball chair will come sanitized, deflated and w a pump. Open to all offers within reason. Thanks in advance:)
