Mini Bowling Set

I am a BBW and can use this chair for working at my desk. I do like the back support it provides. But, It's uncomfortable to sit on it for too long. When rolling back and forth, the wheel locks a lot. It feels like it weighs 1 lb. You can pick it up and move it with ease. If I took the ball out of the cradle, I wouldn't be able to work at my desk. It looses all of the height and I feel like a little kid at the desk, trying to see the top of the table. (I am 5'6") The discomfort in sitting for too long, might be the change in sitting. From a sturdy chair to something I have to control myself. :) Overall, I wish it was a bit larger and taller. Wish the wheel didn't constantly lock on me. Other than that. It's a great inexpensive alternative to the better models out there.
