Does this ball have sand or weight in it to keep it in place? I want to use it for a desk chair at work and to not want it rolling away when I stand.

No, it does not have any sand or weight in it. I don't think it would roll very far, unless you are on a very uneven surface. Just push it under your desk like you would a chair.

I use this ball at work, and rolling away when I stand up is not an issue. Some of my coworkers have added sand, but the majority have not.

It was not designed for wheels. As designed, the ball actually sits on the floor, with the base providing stability. Sturdy as it is, putting all the weight on just 4 pressure points may lead to structural failure over time. Not advised or recommended. If attempted, it would be done at your own risk.

Yes................. I didn't use any sand!You have to help it in but it eventually goes down and the top side comes up! :-)

There is a small round flat part on the bottom, maybe 3" across, that allows it to sit still without rolling around however the flat spot is small and it's very easy to knock it over and send it tumbling so I wouldn't put it somewhere that it might be in the way.

It rolls pretty well. Of course, it depends on the carpet. It is a very thick and pluffy carpet, then I don't know the answer but for corporate office carpet, it is great.

No this ball is not weighted by sand. You would have to buy a stand to put it on. It will roll away.

No, it is soft plastic. I don't believe you would be able to roll an office chair around on it!

I did use a larger ball to sit higher to my desk, BUT after using this base I sent it back - a wheel lock was broken and I couldn't get the company to respond to send a new wheel. Also, all the benefits of exercise are gone with this base, because your muscles don't have to work to keep you balanced, and it's just like a regular chair. I suggest you use a large ball with no base and it works very well.

this one will stand up on it's own when not in use. There where a lot of bad reviews with the ball one with frustrated parents because it would not do that. it falls over.

The ball itself , It will squeeze flat yes. It doesn't stay flat on its own. It's like a spring .

Well, by name, it is a different product. But what they both have in common is the inclusion of sand within the ball to keep the ball from rolling away. The Stability ball comes in three different sizes according to recommended height.

The ball is made of a vinyl. Feel is very similar to a regular beach ball, but it is a heavier gauge material.

It sort of rolls, just backwards and forwards. It's an extremely simplistic design. Definitely no standard casters and rollers that you see on a traditional office chair. That's the least of the problems with this item, though. The foam padding is poor and ends up hurting your tailbone after about a month. If you know someone who can re-upholster the seat and knee pad, it's an okay chair. Very easy to assemble. TERRIBLE to sit on after a month.

no but because of the material its made of, it doesn't move/slide around. i found it to be pretty sturdy.

No. This ball does not have sand in it. It actually comes flat and you have to blow it up yourself.

no it doesn't,I use it on short carpet so I don't worry about it rolling out from me when I go to sit down.I also don't need to grab something when I need it to roll.I like the smoothness when it rolls with the use of my foot. I hope this is helpful for you?

Since the bottom has a rubber like material on the bottom, it does not move. Hope this helps.
