Retrospec Exercise Ball Base Workout Accessory, Alternative to Office Desk Chair or Pregnancy Birthing Ball; Fits 55, 65, 75cm Exercise Balls; Compatible with Resistance Bands

Looks super nice with exercise ball. Not only does the ball not roll away, it makes it look like there was a plan. Does not really stabilize significantly if wanting to turn ball into chair, just use the ball alone and works fine.

This does exactly what I needed it to do, raise my yoga ball up a few inches so I can work comfortably at my desk. Well made, doesn't immobilize the ball which would negate the benefits of sitting on a yoga ball. Perfect, great value for the money.

Overall, this base works as advertised. It will keep your stability ball from rolling away whether you're seated on your ball or using simply using it for storage. I only have one complaint about the base: it lacks any sort of rubber feet or grip for use on tiled or hardwood floors. The base itself moves if you give your stabiity ball even a nudge on these surfaces. Aside from that, I have encountered no problems with it.

I’m using a stability ball as a desk chair until the corona work-from-home is over. I received this ball holder today, and it helps to keep the ball in place without rolling around. I have it propped up on some mats to give it more height, but at some point, I may purchase a larger ball. The ball I’m using is 55 cm, and I’m short with a taller desk. This holder is great though. Exactly what I was wanting.

I bought this so I could keep my ball (75cm) in place while I was working. However, it seemed to be easier to keep my ball in place while sitting without the base. The only benefit is that the ball stays in place when I stand up. This is not that much use to me. So, unless the ball you use keeps rolling away every time you stand up (and it is annoying), this may be helpful but know that it will not do much to help the ball feel stable while you are sitting in it. The base is much to low to really provide stability while sitting on it. I would save my money.

Good product for the price and useful for storage!

I love this! I have an exercise ball that is hard to keep in place between different exercises! This is exactly what I needed. You just roll the ball back into the base and it stays in place! Excellent buy!

The base is too big for the ball so it wobbles (defeating the purpose of the base). Also it's slippery so even if it does stop the ball it allows the ball to keep rotating. Should have read the other reviews before buying this item.
