the price was pretty good, and the shipping was even better! I am 5'2" and have a hard time finding exercise equipment that fits me, this ball is perfect!

I was pleased with Overstock in their fastidiousness in shipping in delivery, but my girlfriend was very dissatisfied with the ball itself. It was worn around the area to inflate, and the ball does not stay inflated very long, losing air during her workout. I feel like I bought a used ball. It now lies used twice in two months because it won't stay inflated while she uses it so I have to find another one for her to use. Do not recommend.

I bought two of these balls for chairs. They work great but it took a few weeks to get the plastic smell out of them. Smell was to the point when you opened the door you could smell them.

I was so impressed with the exercise ball that I recommended it to my sister and she ordered one also. The value and the quality are great! Thanks for a great deal!!!!!

These balls are great. My husband and I use them instead of office chairs. We work from home and found they are great for extra excersise and posture. We bought two for our daughters 7 - 8. So now when they are on the computer they get the same benefits!!

My son's physical therapist recommended a large exercise ball for use by my 8-yr old son who suffers from hypotonia (weak muscles). He can sit on the 55cm ball while watching TV or playing on the computer and give his trunk muscles a work-out while doing so--helping to improve his overall balance. It inflates with its own pump easily and holds my 50-lb son just fine.. The Overstock cost was cheaper than the same exercise balls offered through physical therapy websites.

This smaller ball is perfect for me since I am only 5'2" tall. The larger balls don't work for my short legs and arms because my feet won't touch the ground and they put too much pressure on my wrists. With this smaller red ball, I can balance myself better and finish my workouts.

These things are awesome. The ball is more tan than shown in picture. Still my family loves . The most comfortable and exercise in the house. useing some muscle you can move them anywhere.

I sit on this in the office in lieu of a chair. Holds up great, doesn't lose air, great value.

Wow! Who knew that such a minor change could make such a MAJOR difference?! Just sitting on this ball while watching TV, knitting, whatever, instead of sitting on the floor or sofa really surprised me when I "felt" exertion from my leg/ab muscles. It feels really great to get a little workout when I'm doing nothing....now I'll really enjoy using my resistance bands while relaxing for the evening. This durable and affordable fitness tool is definitely a great buy--I have GOT to tell my fellow couch-potato friends about this, hey, maybe we'll like "bathing suit season" this year.....

I'm an abs crazy excercise this ball is very good and perfect for my size work very good and fast shipping

This exercise ball is working well for me. My only complaint is that one has to pump air into it for quite a while to get it completely filled.

Product exactly as stated....great price. Haven't been using it that much due to an injury (not ball related!).

I needed an exercise ball suitable for my 5'1" size, and this one was perfect. It was easily inflated yet strong enough to support my weight. A nice addition to my exercise props. Overstock has always met my expectations for merchandise I have ordered.

Good - the plastic plug to the ball and air pump seem flimsy, but no problems after 1 week of use.

I love sitting on a ball at work. This is so affordable, comfortable, and easy to set up with the enclosed pump.

The product arrived right on time and was exactly as advertised. Thanks for the great service and value.

I love this big red exercise ball. It's fun and bouncy and I can roll all over the place and do all kinds of stretching and bending exercises. It really helps my back when I need a quick massage and my spine gently cracked. Yes this ball has an odor after you inflate it, but it eventually goes away after 2 weeks-so just be patient. The smell reminds me of a thrift shop so it really didn't bother me that bad. I'm glad I purchased it after all.

the ball is great, i inflated it weeks ago and used it multiple times, and it does not seem to leak air at all to my knowledge. the only thing i wish i had was a band to put around the ball so i know if it is fully inflated, or over inflated. i had to guess. thanks again, overstock!

This ball smells so bad! I have not been able to use it because it smells like moth balls! I am thisclose to throwing it away, but I am trying to air it out and hope that it goes away....
