I just received my new chair last week and it was easy to setup and is equally comfortable as the first version of the chair I purchased. This time it comes with a free seat cover, so that is a bonus. I have not been able to find any similar chair on the market -- this is SO MUCH better than any of the standard pilates ball chairs because the wheels glide perfectly, the chair height is adjustable, this chair is safer (the pilates ball chairs don't typically have a "fixed" ball so when you sit you risk the ball slipping out from under you), and it takes up very little space. The company has since followed up with me to make sure the chair arrived and was working well, and I am completely amazed at the excellent service I got from this company. They truly care that customers are happy, and that (combined with the 3-year warranty on this new version) should give everyone comfort in purchasing this chair!
