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!

Hi, Susan. It's not too high, it should work perfectly in height but the seat is very generously sized. It's wider than what I think would be standard. It's a beautiful chair no matter where you put it. One recommendation on the assembly if you buy it; put the brackets for the back on with loose bolts until you have them both in place and the back rest attached, then tighten them. I put the first on, tightened it, then the second but they were then spaced too wide for the back. Just a tip. I hope you love it, too if you buy it.

I have only used the ball that came with it but you should be able to use a bigger ball with it. The worst case would be that it would be too tall to use the back rest.

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.

I'm 5'2" and this ball works great for me. It's just the right height to balance on like a chair and they don't say this on here, but it's also weighted so if you fall off of it - it doesn't go far. Hope this helps!

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.

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 did sag, but that's what every kind of plug do to my laptop. I just stick a soda top under it so that it won't. When I put it in without a top, it still does no damage.

I have noticed a very very slight tilt. It's only noticeable if I pull my feet off the ground and lean the chair all the way back. If I do that it will start to spin very slowly. I figured that it was due to the fact that I lean it pretty heavy anyways and I am 6'4" and 350lbs, so not a little person. Other than that the padding and stitching and everything else is still in fantastic shape. I have only had it for 6 months but I spend probably 12+ hours a day in it.

I weigh 124 lbs and had the same problem. Ball does not hold air. Chair has been sitting in my office to the side since I bought it & I intend to return when I get the chance. It is DANGEROUS!! Have gone back to my "regular" chair of just a larger exercise ball -- no wheels, but much safer!

The first thing you should consider is the desk height. When you sit on a chair or a ball, the distance between your legs and the top of the desk should be a couple of cms. Depending on the height of the desk, you can make the first judgement call on the size of the exercise ball. If the height is adjustable, great. If not, measure the distance from the ground to the top of your desk. Next, if you read the forums, you will notice that they recommend the 65cm for a person of your height. Similar to another user, I went against that recommendeded size and chose the 75cm. However, I have not inflated mine to the full potential. The key factor is that your legs should form a 90 degree angle and still be able to plant both feet on the ground. I use the 75cm ball as a full time office desk chair replacement and am very happy with it. My desk is adjustable and hence this helped. The 65cm would have been a tad too low and hence my decision to go for the 75cm one. Hope this helps in your decision making process.

I'm 5 foot seven and the chair was too high for my feet to touch the ground, and that was at the lowest setting it would go. I only use it occasionally at my desk. I had to purchase a different brand you use on a daily basis. But the chair was at a good price. I hope this was some help to you. Otherwise I think it would be comfortable it's well-made.

I bought my chair little over a year ago. I love it and it is low like a beach chair. Hope this helps.

Hi! We are a similar size. I love my obus forme! Have had it for at least a half dozen years and it has saved me many times over from unbearable back pain due to poorly designed chairs, seats, work stress etc. My new PT approved it and noticed that I am wearing out a part of it due to my spinal curvature and my tendency to lean my weight to one side. So do get support for your office and travel, but also be sure to check in with a PT if you have chronic issues.

I (150 lbs.) used it for three weeks this autumn and was happy with it, but I think it was beginning to sag just a little the last few days. I'll be using it again for a while after Christmas, and will update if I develop any concerns. It is low to the ground, and a bit narrow, but one gets used to that.

As I recall, the manufacturer has a height-to-size-of-ball suggestion. That is what I followed and got the 65. I am 5.5. As far as the computer desk or art table is concerned, it probably depends on the height of the table. I know that when I sit at my computer desk using the ball, I am lower than when I sit on my desk chair. Since the idea of getting a ball is to help your body, you should probably follow the manufacturer's suggestion regarding the ball size. Hope this helps.

My answer would be to get one of the balls that is specifically designed to be a desk chair. I think that if I had to work on the desk sitting on the ball could be very distracting. This is just my point of view.. I am not young and athletic.
