Bests & Worsts Reviews from Amazon

I and 3 of the girls that work for me got one of these "chairs". Two of us had been using a regular exercise ball, but due to the fact we are up and down alot during the day we decided to try the ones that are on casters. The "chairs" arrived sooner than expected and were easy to set up...well, except for the air pump, it was cheesy. We used a better pump we had on hand. The only problem I could state is the fact that the brakes on the casters will lock on their own, but it hasn't been a huge problem. As far as the total experience of sitting on the ball chair all day at work, getting up and down and moving from the keyboard to the file drawer without having to get up (as I had to do with the regular exercise ball) it is a great chair! The exercise ball by itself took concentration and it was not good to wear a skirt or dress while sitting on it. With the casters it's no problem to wear a dress. One of the girls had been using the Wii Fit Board prior to sitting on this chair. After about a week or so her fitness scores went up on the Wii; for better balance and core fitness. All of us have noticed better posture since using the ball chair. It is possible to slouch while sitting on it, but it is not comfortable to slouch. For some reason it is just more comfortable to sit up straight. One of the girls had been having minor back pain and she said she hasn't had it since using the ball chair. We do get allot of comments from customers about how weird or funny it looks, but it has not deterred any of us to go back to a regular chair. It just gives us a chance to applaud the attributes of how much better our balance, posture and core fitness is and tell them "We are always on the ball". Of the four of us that bought the chair, we all like it 100% and have not gone back to the regular chairs provided to us by the county. We have all been using the Balance Ball Chair since the day we got them, 1 1/2 months ago. 10/7/2010: 2 YEARS AND 2 MONTHS LATER AND WE ARE STILL USING THE BALANCE BALL CHAIRS. One of the balls got a leak and she had to buy a new one. Other than that no problems. I have since hired a new girl and she also bought a ball chair like ours .... I highly recommend the chair ... plus they are tons cheaper than any office type chair.
