Could I use this base with my 65cm ball? I love my ball and it's inflated just right, but it's too low for sitting at my desk. I am 5'6" 170 lbs.

Hi Gretchen, From what I can tell by measuring my ball to 65cm, I don't see why not. There is plenty of room in the chair for a bigger ball. You can always deflate the ball and adjust the base height until you get the comfort level you want. Hope this helps!

About a soccer ball size, you may be able to use it at your desk. Ha ha depends on how big you, your desk & office are. Sorry I don't have dimensions.

I have a large exercise ball that is about 18-20" high (radius measurement) and it works great. I think it would be fine for anything that you really want to be careful about how much air you are adding- and not to overinflate the ball, like if you used a high powered home air compressor.

I bought my ball when I was pregnant too. I'm 5'6 and bought the large one. I loved it then and still use it now. Baby even likes being bounced on.

The diameter should be 55 centimeters, from one side to the other side going through the center. I think some companies may make the same size in different colors. My understanding is that the size should be on your ball, either near the brand name or around the end where it is to be inflated. I would check for a size, perhaps you were sent a wrong size.

I am 5'6" and using it. It is the same height as my chair seat. Some variance may come from how much air you put in the ball, but the higher you go the harder the seat. I spend some time in a regular chair, and some of my time in this chair on any normal day.

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!

My friend who is 4' 8.5" stopped by this morning and tried my chair. She thought it was great and had no problem - in fact, she is going to put it on her gift list. She said she had no problem with it rolling away from her (although you do need to be careful about this...I think my casters are partially locked). Her legs were not at 90 degrees, they more followed the contours of the ball, but her feet were on the ground, and she was able to move the chair easily with her feet. I don't think her heels were more than just lightly touching the floor though - but she was barefoot. She was able to easily sit on the top center of the ball, and thinks it is very comfortable. She can't lean back against the backrest, but this is okay since you aren't supposed to lean against it anyway. BTW, the instructions for inflating the ball say to blow it up, then check it in a day since there will likely be some leaking, or perhaps it just stretches out, and fill it again. This is exacrtly what happened with mine, and after I filled it the second time, it has been fine. My ball might be a little soft, which might make a difference to her, but since I am big, it might be my weight. I hope this helps, and I would stress that you be careful when first using the chair to have a good understanding of how it moves, particularly when getting on and off.

You purchase a ball size based on your particular height and how much weight you need resistance for based on your weight and what you might be lifting if using it with free weights. I read numerous review of cheaper exercise balls that burst on people skimping on the price. I certainly didn't want my 82 year old 6'5" father falling to the floor while doing his exercises.

I am 5 4 and weigh 130. I ordered the blue ball which turned out to be way too big. Tried to return unsuccessively. Also, ball never leveled out. It is sturdy. Simply wrong size and poor customer service. Good luck!

Not having tried it. I don't know. But the pressure in a big air mattress while large may not be a great as an erecise ball under load. But for the few dollars involved. Try it before you chuck yhe exercise ball

I am in a very small area and when you raise the desk part it comes to you. If the base will fit on your desk you should have not issue. BTW. I am really enjoying mine!

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.

My ball is a "Go Fit" and I think it is 65 cm. When I looked at it, the six is a little worn (the paint), but it is either a 55 or 65 and I"m betting 65 cm is kind of the standard. Mine fits perfectly and now I can use my ball for computer work or paper work and not worry about falling off, which I did a lot before. You can change positions, bounce, etc. It is GREAT. Susan

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!

This ball will be the right size for you though you may find that it is too low for a standard desk. I highly suggest utilizing this ball as a chair though you may wish to lower your desk or find a "chair base" that fits this ball size.

I bought this in July. I'm only 5 inches taller than you & it's plenty low enough for me. Maybe a little lower than I would like even, but overall I love it...so I don't think it should be a problem. Hope this helps.
