I like it, you have to get used to it, and it took a little time to put it together, but I like it. I had to add air the following week after I put it together b/c I could tell something was "off" about it. Once I did that, it was fine. The paperwork tells you this too. Also, wait overnight and then add more air the next day b/c the ball is too small when you first put the chair together. I like the fact that it locks on two of the wheels.
