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.

You may have to physically blow some additional air into the valve to fully inflate - and thus fully extend - the mat.Only complaint I have with mat is I'm a 'side sleeper' and the 2" thickness is still not enough to avoid pressure points at hip and shoulder. (Adult male, 5'9", 195#.... Maye the 195# thing is more of the issue!!)

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 havent measured the size, but it's a regular size ball. I can't recall if it came with air, but think it didn't. I frequently use the pump to fill air in balls, so don't think it's an issue. My son still plays with this ball every day and loves it

This really depends on your personal squatting needs. 75 centimeters is pretty large for an exercise ball in general, but I've never tried using a ball for squats, and I'm not sure of your technique.

I understand, I worried too. I am 225 and I have room to "grow" on this ball. It is anti burst but does not mean a 900 person can use it either. I recommend staying under 600 lbs. I use it as a chair at my desk and bounce on it freely. It is great exercise, seems silly that I bounce but my legs are weak and I find this very good for strengthening them. 75cm, mean how tall the ball is when fully inflated. It is recommended for a very tall person. I hope this helps you!! Good luck.

If it arrived in the cold, you'll definitely want to let it warm to room temperature before inflating. And, you really should follow the instructions about inflation, as these folks know their product best. I think the wait is because you don't inflate it fully at first, let it sit and finish inflation the next day. With all of the balls I've bought through the years, I've also had to add more air after a couple of weeks, but then they're just fine.

It should be tight (or the ball wouldn't bounce back very far at all) but will fit right if you have it and the straps on right. Look at the picture and make sure you aren't doing anything wrong. You may want to try all of the corners first and then fill in the sides.

Yes, it deflates and becomes small and light. It's good, but the ball is awful -- take along your own; any cheap, small rubber or plastic ball will do (about softball size: 12"-16" diameter would be fine).

Hi Nancela, After the first fill, you'll need to occasionally add air to the ball. Once you settle on a good PSI you should use the gauge to test if it's where you like it and maintain that setting.

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.)

Depends on the type of ball, I guess. I tried to use it for a 75cm yoga ball and it failed miserably.

Hi Alison, The ball should have come with a plastic straw. Insert this into the ball and inflate by blowing by mouth. The ball doesn't have to be inflated beyond what you can do by mouth. Just be careful when you put the white plastic plug in the inflation hole to seal it. This is where you can loose some of your pressure. This may take a few tries until you get the technique. Be ready to cover the hole with your finger after taking the straw out. Take the straw out of the ball while you're still blowing into the ball. Good luck!!

This is 65' inflated and it will take a long time to inflate this ball. There are small pockets that must be inflated properly with a hand pump or a foot pump. It will take some time and doing and in my case my sons were excited after each pocket was filled. It is fun though and worth the expierence for the kids and will tire them out.

Justin, I have not measured. I have enough air in the ball to hold me up, so I can exercise. I had to fill twice. OK mine is also the same as yours. If you measure to the center of the ball it's 30". Does this help???

Mine was not inflated enough when I got it, however one could have played with it in a pinch

There is a valve on the one side. You should be able to re-inflat with a needle - like one used to reinflate a basketball. Go to your local sporting goods store and they should be able to help you.
