Does the ball sag really low when you sit on it? I want it for a desk chair at home, so I want to make sure it's the right height.

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.

I got one of the smaller sized ones and when I sit on it I am sitting at a height just over the middle of the ball...so I dropped about 1/3 of the way. I'm sure the size of the ball and your weight will determine how low you'll go but in my opinion, this ball doesn't sag like others I've had in the past.

I got the 55cm size, which is relatively small, because I have short legs, a 28 inch inseam. It does sag some when I sit on it, but it is still good for using at my desk at home.

Mine does not sag much, but since I am short and using a 55, it would not be a good desk height. I think most people using them at a desk are using a larger size.

I'm 5'10" and about 210lbs. the 75CM is the only way to go for this. pump it up to 75CM and use it for a week. Then you may want to pump it up again since the material will stretch a bit. after it stretches out, you can inflate or deflate it to whatever is comfortable. i like mine about 68-70CM so you sag into it a little, which makes it the perfect height to work at a desk. i use mine at work 40 hours/week for 3+ years. Best thing ever!

That sounds truly strange as these balls are very sturdy. Is it possible it was defective in some way? I did, however, purchase a bigger ball. So far, it has held up pretty well. Check how long you've had it to see if it is still covered under their warranty, and let Gaiam know about your experience.

I have found that after a few weeks the ball needs to be re-inflated. The firmer the ball, the higher you will sit. Hope that helps!

I really like the chair. It looks just like the picture, but please note, the seat cushion is VERY firm. Because of this you sit up pretty high. (I am 5'6"). Hope this helps.

Yes its great for sitting. Right height and surprisingly comfortable. Really a great buy. I got them for trade shows and many many people sat on them and they kept up well. The storage is really nice too. I wouldn't hesitate to get one for my home. Hope this helps- ag

I am 5'2 and have the smaller ball; I can tell you it sits pretty low to the ground. The larger one may work with a very short desk, but the problem, I think, would be balancing on it for long periods. Why don't you just take it to work and use it to stretch during breaks? Hope this helps somewhat.

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.

Its supposed to just "sit" on the chair, and it can be a little loose, however it generally does not move around when I sit on it, and I've never had an issue of it sticking to my legs as I try to stand up

i tried it and it was not to comfortable. You would probably be better off with an exercise ball chair. It is also on the large side and doesn't easily fit in a regular chair.

It should. The frame keeps it very stable so that you are not rolling on it. I go to a chiroprator and she was glad that I bought one with the frame for stability. My office has carpet, so that probably helps. As for the height, I had to fully inflate the ball and then, let air out until it got to the height that was best for me. I am 5'3". I hope this helps.

yes. in fact it is tall by default, one of the things I personally don't like so much is that at the lowest setting, it is a little higher than what comfortably works if you are seated on a chair. but that means it is perfect for you I guess !

I weight 220 and could still put more air into the ball to make it firmer if I weighed more. so i'd say give it a try. the frame is very sturdy with the 5 rolling casters. I don't lean on the backrest, so don't put any weight there, only use it to "scoot" in to my desk after sitting on the ball. i LOVE the chair and don't think about my low back at all anymore - it doesn't hurt and my abs and torso have gotten worked out each work day! i was gone for a week and my co-workers fought over time using my ball chair. a few of them are ordering one for themselves.

The seat isn't rigid because it folds. I wouldn't use this seat unless you are able to support yourself and put one leg over at a time ,and if it were me I wouldn't take the chance. To answer your question, yes the seat sags when you sit on it.

I'm 5'8" and find it very comfortable. It's ability to flex/lean may be why it seems to accommodate so many different people. I needed to take a break after the first 3-4 hours using it because I felt tired, but I haven't gone back to the office chair since that first day.I don't know if there is a way to raise or lower it. That's a good question for the seller.

I was told by my chiropractor to get a ball to sit on while at my computer. He said to get the 55mm sz for my height which is 5'1". I guess it would be the same for you. For me, sitting on it at the computer seems to be a little small but I do use it. I like a 65mm myself. Read all the post about this ball before buying it.

That weight will be pushing it. I could see sag happening over time. Not sure I would put more than 3-4 pounds on them so as to be totally comfortable. There is a lot of pressure on the nylon ball that is clamped in with the "jaws." It fatigues over time.

Very easy to assemble. My only thought is the size of the ball, make certain it is the right measurements for you. I love my Sivan Adjustable Back Balance Ball Chair.
