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 rolls up well. after leting it lay out for a while it went back to a smooth surface with no kinks. Walking on it doesn't affect it either! we have a one year old whod loves to run on it!

It has rubber circles/feet on the bottom that keeps it from moving. Just sits on the surface. Does not attach. We like it.

Yes. The weight makes it easy to roll around without tipping over, yet stays where you put it.

I use it as a desk chair. I sit on it for at least 40 hours a week. I have the largest size. It is firm enough to keep you at a decent height. I purchased this brand of ball after having issues with a squishier brand of ball. I'm completely satisfied with my purchase. The pump that's included is better than any other I've used so far.

It's a pretty big ball. I suppose it would fit in a chair, but you wouldn't be able to then sit on it.

Correct, there is no bounce to this ball. I prefer it though. I like the soft, sandy feel.

I have not had any problems with this. The weight naturally shifts slightly when slammed, but I have not had problems maintaining an even shape. The ball bounces nicely off of the ground and against hard and soft surfaces.

None, it works by gravity. There is a slight elevation which makes the ball roll back to you.

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.

I feel it should work. My office chair is pretty big and weighs roughly 30 lbs...I take that back. I didn't want to give you misinformation so I decided to actually weigh it for myself... Turns out my office chair weighs in between 46-47lbs, I couldn't believe it! I knew it was heavy, but not THAT heavy. LOL! I sit and roll around on it daily for hours at a time. Never heard it crackle or felt like it was going to buckle.Keep in mind- I weigh 140lbs and usually sit on it with my 2 year old that weighs roughly 25lbs (last time I checked)I've had the mat for several months now and it sits on carpet of a decent thickness. It's not plush but it's not low pile either.Hope I answered your question.All the bestB. I feel it should work. My office chair is pretty big and weighs roughly 30 lbs...I take that back.

Yes, it's better than other stability balls because it has some sand or something in it so it doesn't roll around, it stays put if you're not putting any pressure on it. Only like 8 oz in it so you can still move it around. It's great quality

I haven't come across a weight limit, but I will share this with you...A coworker who weighs more than I do (145) was using my ball chair when I was not there and I noticed the chair wasn't "gliding" well. It was because her weight had pushed the ball right through the frame and it was dragging on the floor. You can't blow the ball up to be firmer because then you are not aligned properly in the chair. Personally, I would skip the frame and just sit on a ball.

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.

If you mean if it sands in circles, I don't know but it would not move in circular motion. If you just leave it without directing the movement, it will "vibrate". It's easier to move it in straight lines than in circles.

Once you are seated, it does not move around. Getting onto the chair from the side (I use the Drive lightweight chair), it will shift a bit, but once put back in place, it stays there. Because the cushion has some weight to it, it stays in place much better than others I've used in the past.

It moves a little, but it stays more or less in place. My desk top is stone, which might affect that.
