Sivan Health & Fitness Yoga Stability Ball and Pump

I bought this stability ball to use as my desk chair. Since it was an experiment, wanted to find one that was a reasonable price. Also didn't want a shiny, glossy surface. (This ball has kind of a pearlized finish and blue is kind of pale royal blue.) This ball seems to be good quality. No problems so far. As with most inflatables, it loses a little air over time, but very slow. I have only topped if off once in 2 weeks.The 65 cm is a good height for my desk when fully inflated, but it is a bit more comfortable after it looses a little air...... then it's a tad short. I might try the 75 cm next time. I am 5'4" female.

My Gaiam yoga ball for my yoga ball chair was punctured by my cat. Since i work from home and use it as my office chair, i needed a replacement asap. Amazon does sale the replacements for Gaiam ball at a price double the price of this ball. I ordered the 52 cm which was the size i needed. The ball is excellent quality and certainly equal to the gaiam ball. In fact the pump and inflation process seemed much easier than other balls used in the past. Great product.....hopefully my cats will stay away, but should the need arise, i'll buy again.

I purchased this for my daughter to use at school - her class allows the use of yoga balls instead of regular chairs. The pump is a little flimsy, but within a couple of minutes, we had it inflated and ready for action! The plug does a good job of keeping the ball inflated, but is a little tricky to remove if you want to deflate the ball. Overall, a great, low-cost yoga ball.

Unfortunately this ball burst after a year and a few months of using it every couple days on average. I was using it as a desk chair and occasional back stretching tool. It was great for the time it lasted. I don't think it was made to be sat on so often though.I did replace it with a different brand that specifically said it was sturdy enough for daily use a desk chair.

I've used other stability balls to sit on at my desk. This is the perfect size for me and really help my lower back pain and works my core muscles. The only issue I seem to have is that it loses a little bit of air within only a couple days where as my other one would not have to be pumped up for weeks or longer. This is a good sturdy ball.

I ordered this ball in hopes of using it in my latter stages of pregnancy. The ball I bought at walmart for my last pregnancy was only about 10 cm bigger and was a bit too big for me, so I figured this would be the perfect size. However, this is definitely way smaller than advertised! (and I am thinking they probably sent me the 52 cm one instead of the 55 on top of it!) When fully inflated this ball is barely bigger than some of the balls my 2 and 4 year old have as toys! and I can guarantee my daughter is going to think its for her when she wakes up from her nap. It might as well be, because I won't be getting any use out of it! Definitely disappointed! I can't even exchange it for a bigger size because they appear to be out of stock for anything bigger. On top of that, this ball came in just a bag inside the brown box amazon shipped it in, as if it had been used before. No original packaging of any sort.

Good product that has held up fine so far, No instructions were provided with the package for use of the pump and a how much to fill the ball, but it's not rocket science either, I used my portable air compressor and just guessed at how much was enough. I can't comment on the quality of the pump, but it's pretty basic. The ball hasn't seemed to lose any air even with daily use. Overall, I'm very satisfied with the purchase.

This gets passed around my office when I'm not using it, and everyone loves it. If they are taller, they deflate it slightly, and if shorter they pump it up more. No complaints, happy I purchased. I have an adjustable stand-up desk and even when I'm standing I'll use it, resting my knee on it and changing feet. Makes stand-up working a little more interesting and comfortable.

Does the job.

This ball is the perfect size, and the pump is effective and easy to use! I Would definitely recommend it.

We used everywere I love the color and sizes.

Product was advertised as coming with a pump but there was no pump. Luckily I had a different pump from another ball, or this purchase would have been useless. Very poor.
