I'm glad that I ordered the Exercise Ball Base, I am 68 years old with some balance issues and I am using it to help keep me stable until my balance improves, The base was easy to assemble, is very sturdy and I am working toward the day when it will simply be the parking spot for my Live Infinity Ball when not in use. P.S. The Exercise Ball is very sturdy and fun to use. Great products and great company!
I am using the base to keep the ball stable while at my desk at work. It stabilizes the ball and is absolutely necessary if using the combo for a seat.
