I'm 6'5" 270 pounds. So when I looked into stability balls I was really concerned with whether one would support me. So far, so good. I got it yesterday, blew it up in a few minutes, and sat on it (hesitantly at first) for over an hour. Then worked out for about an hour. It seems very durable and able to maintain my weight without a problem. The exercises on this thing are super effective, as I can feel today. The ball is just right as far as size goes.
Someone complained about the pump, but I found it efficient. It's like a huge syringe. It worked fine. It only took me a few minutes to pump the ball up and that was with my one year old hanging on me so he could mess with the ball.
If something happens and this product fails in some way, I will immediately update this review so that anyone who's concerned can know. So if you don't see an update, the TKO's going strong.

I got this ball to use as a chair to bounce my baby while I am holding him and at the computer desk. I think it is excellent and has helped with better posture without any thought. I also end up doing some excerises on it, just because it is there. It does not have the ultra shiny surface as is noted in the picture. Also, it is a pretty standard size I believe and is not too tall for me. I can sit comfortably, with my knees at 90 degrees and I am 5'4". As for the reviewers that are not impressed with the pump: well, I don't care. I don't plan on deflating and inflating this thing again and again.

I have two exercise balls -- one for home and one for work.

This is the ball that replaced my office chair at work. I sit on it daily, frequently bounce on it when no one is around, and it has rolled around my floor with coworkers a couple of times. I've only inflated it once (the initial time) in the time I've had it -- over three months!! I weigh about 130lb (+/-) so I don't add a *ton* of constant weight on the ball. It has lost *some* air (it's not perfect after all), but it's still very firm. (I will probably re-inflate it this week or next.) Three additional bonuses about the ball: (1) since it's a dark color it doesn't pop out at people as they walk by me at work; (2) it's neither sticky nor overly smooth; and (3) it's anti-burst. The ball has a good texture that keeps you in place but doesn't pick up lint/dust. Some balls seem to attract it. Also, if you've seen that episode of "The Office" ([...]) you can appreciate the importance of an anti-burst ball. I haven't tested out this feature (and don't plan on it!), but I am glad that it is there since ANY stability ball can be popped.

The exercise ball that I have at home (GoFit) has lost air much quicker and I don't use it 1/10th as frequently! When I replace my GoFit, I'll definitely go with another TKO!

I purchased this largest of the fitness balls (75cm) eventhough I am 5'9". I am a physical therapist and am very familiar with these so called "Swiss therapy balls" as they are used extensively in my profession. I wanted the largest ball for personal preference, although the 65 cm ball is the recommended size for my height. If you want the ball for doing wall squats (ball against the wall and behind your back) or for lying over on your back to stretch your back into good extension without feeling like your head (or hair) is trailing on the floor, then you may want to size up as well. There are many other exercises that are better accomplished on a ball that is a bit larger as well. Also, it has been my experience with many of these balls that it can be difficult to get them blown up to the full stated cm circumference. The instructions in the packaging tell you to NOT use a automatic tire pump, and to use ONLY the hand pump and inflator tube/pin provided. It is a challenge to get the air into the ball this way (with the hand pump) after it is approx. 80% of its stated size, and I don't mean just this brand ......... all of them are that way. Also, if you know you are not going to blow it up to its full size it will have a bit softer feel which is another attribute I was looking for. When they are blown up to their full stated size the "anti-burst" balls can be very firm and some find that uncomfortable. The TKO ball is a nice, sturdy ball. The material is very substantial and a bit firmer than some therapy balls especially if it is fully blown up to it's stated cm size.

I purchased this 65mm TKO ball after seeing Spri balls promoted on tv as a good alternative for an office chair. I wasn't sure how much I'd like it, but wanted to make working at my desk more physical and for $15 it wasn't much of an investment - far cheaper than my leather chair. I've been sitting on the ball between four and six hours per day for two weeks now and it's holding up well. There hasn't been any leakage in that time and the ball is very stable to sit on. Even on a glossy tile floor, there's no fear of it rolling out from under me.

Sitting at a desk for long hours, my tailbone often gets sore, even with those u-shaped pillows, which isn't the case when sitting on the ball, nor is lower back pain an issue. I've found that sitting on the ball seems to promote proper posture or rather it discourages anything but. You can't sit on it lazily. Crouching will lead to upper back discomfort and possible neck soreness rather quickly. But, I guess that's why it's better for you, to make you use more muscles and make sitting more active. It might be best to ease into it, rather than going nearly cold turkey like I've been.

Regarding the complaints that a few others have had with the ball being smaller than advertised or lopsided, I believe that's a result of a failure to fully inflate the ball. The ball is made of very tough, but flexible material that I imagine would be a pain to fully inflate with the small hand-pump that's included. Even with an electric pump that we bought to inflate our portable matress, it took a good ten to 15 minutes to inflate to the 25" diameter recommended by the manufacture. The ball may appear fully inflated at only 21" diameter, but there will still be a few creases giving away that it's not. And, because you're not just filling the cavity with air, but also having to expand the strong rubber shell, that last 4" seemed to take as much time to inflate as the first 21", though I spent more time at the end measuring to ensure the ball didn't over-inflate, so the time could be deceptive. Once fully inflated, the ball doesn't appear remotely unbalanced or asymmetrical, nor was mine smaller than advertised.

If I can ever get conditioned to sitting up straight for long periods, this should prove a great investment. Regardless, for a ball this large and durable, $15 is a great value. compared to many others.

Update:

After months of use, I haven't needed to add more air, even once. I've used this ball as a chair, as an excercise component, and my neice and nephew have enjoyed putting it through a more vigorous testing of bouncing on it more abusively and it's still holding air extremely well. The upper back soreness I previously mentioned had less to do with posture and more to due with a 9000 mile motorcycle trip I took the year before. I've had minor upper-back problems, generated from my years in gymnastics and many more carrying heavy loads in construction. It seems it was past time for an alignment.

I am a proponent of fitness and the intent of my review is not to tout the benefits of using this product. As an active individual, I decided on this item to add dimension, that I thought needed, to my routine. I also intended to use this ball as a supporting structure (chair) for my writing assignments and such. Having used "fitness balls" in the past, I selected this item on reviews. I was disappointed.

This company delivered the product as promised. No issues here.

After inflation and initial use, I was satisfied with the product for the first few hours. Then I noticed that the ball began to lose pressure. I was not successful in trying to find one leak. My product has multiple leaks from the vulcanized seam. I only found them after submersing the surface area in soapy water.

As I am overseas now, with the product, a return is more effort than worth.

Had the product worked (held air pressure), I would have been satisfied.
i do not know if my defect was a one-time issue or a common problem. All I can offer is caution in your purchase.

I love this ball, I don't even mind if I leave it out at my home. It has a bit of sparkly in it. Totally different texture than my old ball. The "Anti Burst" feature sold me as after 4 years w/ my old call it bursted on me during a "Pilates on the Ball Session" luckily I wasn't hurt. (If I had been turned the other direction I could have smacked my head on the coffee table on the way down.)

So I went online and found this beauty to replace it. Love the foot pump too, felt like it inflated faster than my old hand pump.

The ball is quite sturdy, the hand pump is a workout in itself. The sizing is confusing, among all brands, they can't agree. The box says the 55cm is for 5'6"-6'0", I bought this ball under the impression that 55cm was the size for anyone under 5'4". This is my reality: 5'2", 190lbs, looking mostly for something other than the couch to sit on, working on core strength. This ball is smaller than I wanted, my legs do not make 90 degree angle. Maybe I am too heavy, or perhaps after a few days I will be able to get more air in it. It will be great for exercizes where I hold it between my arms or legs, but for sitting on, or push-ups I will order a 65cm ball. My recommendation is to skip the sizing charts, find someone with a ball and decide for yourself which size suits your needs. Shipping was fine.

The ball makes a fantastic "active" office/computer chair, at an extremely affordable price. I'm on it 6-8 hrs/day, and my back and legs feel better than with any other office chair I've used. I'm never going back!

I received this stability ball 2 days ago and it did not have a plug with it. I sent it back to Amazon and ordered a replacement. I got the new ball today and it doesn't have a plug either! I will be returning this ball and buying from a different manufacturer.
