Perfect for a desk chair

I was looking for a ball to use as an office chair. It couldn't be a crazy color because it would be in an office setting and the shiny rubbery ones look like something kids would play with. This ball looked great because it was a neutral gray, didn't have any crazy markings except "DynaPro" on the side, and had more of a matte finish. I was nervous about the reviews questioning the size of their exercise ball, but I decided to get one anyway. I'm 5'5" and most exercise sites told me to get a 55cm ball. When using one as an office chair, you're supposed to go up one size so I purchased the 65cm version. My desk is average height and 65cm would go at least 4 inches above my current chair (which other sites have recommended). It came in 2 days early, a very nice surprise! The ball looks just like the picture and it's made of a thick, sturdy material. The pump was a little odd at first since I thought it was sucking air out of the ball instead of pumping it in. Just put the nozzle in ball and pump as normal. The device will sound weird, but it's working just fine. The first time I inflated the ball, I was disappointed with the size. I was a foot lower than I thought I should be! I gave it another chance and started pumping more. Even if I didn't think it made a difference, I kept putting air in. This definitely helped, it was nowhere NEAR full! After a few more tries, it was almost to the height I wanted. I debated returning it, but the card inside the packaging said to give it 24 hours for the material to fully expand. The ball even had dark "stretch marks" on it where material hadn't fully stretched out yet. This morning I came into work and started pumping in more air. I noticed that once the ball is inflated fully, the pump no longer lets out air as many people complain. Once you push it in, some sort of air lock happens and it doesn't change until you start pulling back the pump again. Now it's the PERFECT height! It's very tight, but after a few minutes of sitting on it, I stopped worrying about breaking it. Hope this review helps clear up some of the questions people have, I was wondering all of this when I first got it!

This ball is the CORRECT size - just give it 24 hrs to stretch and reach full size.

Have had the ball for one week. It seems to be of very high quality, and the hand pump is much nicer than the foot pumps that come with most other exercise balls. I would give this product 5 stars, but am deducting 1 star due to incomplete instructions. Specifically, it does not explain that PVC exercise balls take 24 hrs or more to reach their full size. When I initially received the ball, I fully inflated it and it only measured 55 cm (the next size down), despite the Amazon description saying it is 65 cm (which is the size I need). I packaged the product to return it to Amazon, but right before shipping it back, I decided to contact the manufacturer (DynaPro) via their website. They promptly responded in a few hours via e-mail (great customer service!) and explained that the ball requires a day or so to stretch out and reach its full size. So, I unpacked the ball again, re-inflated it, waited 24 hours, added some more air to the ball, then sure enough, the ball finally stretched out and reached almost 65 cm. So keep in mind, you must wait about a day, then add more air. I've noticed that many manufacturers of PVC exercise balls fail to give this instruction, and think it's strange, since they could probably avoid some product returns by mentioning this instruction. UPDATE 7/30/15: Have used this ball for several months now, and it's been a great product. It has never lost any air, and it is of noticeably better quality and thickness than other exercise balls I sometimes use use at the gym. Dynapro replied to my previous review about needing to improve the inflation instructions, saying they will change their instructions in the future. Thank you! The four-star review I gave previously is now five stars.

Choose this exercise ball.

This 65cm ball is wonderful! Got it for PT and haven’t been disappointed. I purchased a less expensive brand at the same time with the hopes of having one at home and one at work and I had to send the cheaper one back. This ball however is perfect and worth the extra money. Easy to inflate, no harsh smell, and the inflated size matches what it’s listed as.

Excellent customer service and product

The ball came with a small scuff and dig on it. It blew up fine and held my enormous frame. But I honestly answered their email when they asked how everything went. I told them about the small mark and my concern that it could cause the ball to pop and the customer service rep that contacted me was very courteous and helpful. They shipped me out a replacement immediately and I couldn't be happier. I purchased the larger ball and it perfect for me. I'm 6'4 and weigh almost 400 lbs, but I feel completely comfortable on this exercise ball. It has helped me out tremendously with my back problems and gets daily use now. I'm so impressed with it that I convinced my sister, brother and sister in law to buy ones for themselves too

65cm Chair - 3 Months Of Heavy Use And Holding Up Great!

I bought the 65cm ball in silver as a more ergonomic desk chair to improve posture. I've used this nearly every day between 2 to 12+ hours a day for 3 months and it's still great. I feel like it makes me use my core more,and I think it improves posture. It lends itself well to the fidgety, too. I bought this on a lightning deal or I would have bought two. Planing on buying more if it's a lightning deal again, but it's definitely worth the money on sale at an Andrew Jackson and a Lincoln. I chose the 65" after reading other reviews, and works great as a desk chair. The ball feels much thicker material than most exercise balls, metallic silver with a subtle sheen, and textured lines for grip. It takes a day or two to stretch to full size. Included pump works well and I got several spare plugs.

When you want to add a little bit of exercise into your day this exercise ball is a great option

So far so good with sitting on it M-F at work * I'm 5'10" @ 235lb's and the 65cm supports me perfect * I sit on this ball on average four hours a day during the work week. * The pump that comes with the ball is not the worlds best pump when you have to pump it up for the 1st time, but when you need to add just a little air it works well. * About every other week I have to put a couple pumps of air into it * Several people have different brands of exercise balls at work and so far I think this is the best built one and with the ANTI-BURST TESTED at 2000lb you can't get much better than that

Many different uses, and high quality

Excellent tool, for both therapy, rehab, as well as strength training. Make sure to get the right size. The ball is very well made, and comes with two extra air plugs, as well as a plastic wedge to remove plug and deflate if needed; also comes with air pump. Great for whole body strength. Thanks!

5-Stars

Great exercise ball. Definitely feels more heavy duty than my last one and I am much more comfortable using my heavy weights on this and retiring my weight bench to save room in my apartment.

Very Good Quality

Update: I did buy another ball in the 75cm size and I really like it as a chair as I sit up taller and engage my core muscles. Great for exercising too. Very happy with this brand! This is a great stability ball that has very thick walls and anti-burst technology. It takes a while to pump the ball up with the included hand pump, but if you have a small air compressor, it inflates very quickly and easily. I do think I'll go up one size from the 65cm to 75cm because even at 5'7 in height my knees are at a bit more than a 90% angle, so added height would be more comfortable. I highly recommend this product.

Great quality that holds air over time!

There are a lot of poor examples of these balls around, many are too thin, or don't hold air over time, but this one so far has been great, I haven't had to refill it and it appears to be keeping its size/pressure perfectly. I would not hesitate to buy another or recommend these to others.
