I purchased a 75cm ball but could only inflate it to 63.5cm. Does the ball need to stretch a bit before it can reach the 75cm size?

Yes. inflat to the max. wait a few days,use it, sit on it. In time it will stretch out. You feel the difference once it's stretched out.

Hello - the balls do need to be inflated up to 1.45 pounds per square inch [psi]. Thanks!

Agreed. Make sure the ball is out of the locking space. If that doesn't work, it could be faulty. I received one that didn't latch properly and the seller promptly sent me a new one.

No. It's 55cm as advertised. If ball is inflated beyond the designed size, it fails to perform as designed, and defeats the purpose you want from it. You can actually feel the differences and loss in effects.

There is a small plastic piece that holds the air in. To inflate you can use a handheld pump, like the kind if you were inflating a pool float. The pump is not included with this ball.

I wanted to blow it up that full but my daughter insisted on only about 26". It is so important to keep it under inflated. That being said, this makes it quite small for my husband to comfortable bounce. Wish there was a truly larger size for adults. I am using mine for rebounding - just staying in one place and bouncing up and down. Awesome for my knees!

A red Isokinetics anti burst ball, 55, fits very snugly, makes it a little taller. Other colors of the same 55 size need to be pumped up bigger to make them firm enough.

I wondered that also, but went ahead and ordered it. It was not inflated when it arrived and is was probably about 5 inches or so. So it may mean that it will function as a ball from 7.8 to 14.5 inches. One we made small and the other we inflated to the 14 inches. My grandson plays with it a lot.

Hi, this pump should inflate your soccer ball but you need a Sports Ball Air Inflator Needle. Just attach ball inflate needle to Schrader (Not presta )side of pump attachment as you would a tire with a Schrader valve. I tried a sports ball inflate pin with the Topeak Peakini II Mini Pump and there is no problem attaching and locking it in place. I did not have a soccer, football or basketball to pump up though! God Bless!

It's a large exercise ball and fills the space in the chair. The instructions actually tell you to pump it as full as you can, and then the ball will stretch and you can add more air. I added air for about the first week until it was what I consider fully inflated. It hasn't needed more since then. Hope this helps.

I seem to be able to stretch it to about 3.75,but I might check with the company to be sure.

I have mine on the 2nd hole from the bottom and from the floor to the top of the backrest, it's about 30". There are a total of 4 holes for you to adjust the height as you need. As for the ball, mine fits fine. I think the very nature of the ball causes it to expand after you've sat on it for a while. I agree, it feels like it's deflating, but I think more often than not, it just feels like that because the ball is being stretched out. I have mine in my office at work and I sit on it for 8 hours a day so it gets a lot of stretching. I just keep the pump that came with it in my desk and I'll re-inflate it as needed. No big deal.

Be sure to pull the inflation stem all the way out to inflate otherwise you're wasting your breath. (I'm assuming that you can't get any air into it.)

If the ball has a small valve hole like a football, it will not work. The inflator comes with 2 size tips. Both are too large to inflate that body ball.

That would take an excessive amount of time. This product is designed to be a portable, low-volume, high-pressure inflator. If you don't have a compressor, I would ask your friends if anybody has one. Thats the best way to inflate exercise balls. Although you could get a good workout using this :)

Your ball is underinflated. If I remember correctly you should inflate until ball is 22 inches in diameter.At that size your problem will be solved.Reread instructions.

Sorry, I have seen such balls but have no clue what they require for inflation? The pump works great for our air mattress!
