As expected, this is an economy model & smaller than the rectangular wooden board used in physical therapy. Still, it was low cost & allows me to work on strengthen my ankle range of motion after surgery. Even after a few weeks' use, I can still balance much better on the board at my therapist, so I think the larger board would be more beneficial and less frustrating. A fair price for an item I hope to use for a short time. If I had to use it every day, indefinitely, I would have upgraded to a better board.
1 screw did not line up and the guy who put it together wanted to throw it away, the screw (not the chair). I sit in it all day long, and would like to take the arms off, but then it would look less like an "office chair" and my business is very conscious of this atmosphere. I used to sit on just a ball, and felt more freedom and core strenghtening. The chair is a decent substitute, but I'd rather be on a ball. Hope this helps. I also, went with this chair as opposed to the generic thinking it would be more structurally sound, and unfortunately I think it is within the same grade. Personally, I would rather have a different heavier model.
I love this chair! It helps with my slouching and my leg-crossing, both of which I am always working to stop. The only downsides to this chair is that I have to re-inflate it every few months, and the breaks on the wheels are easily tapped, which is irritating, and one of them has already broken off (likely the fault of a student, but anyway). The final thing that I found problematic was that this particular chair was too short for my desk, and I had to purchase chair leg extenders from http://www.gaiam.com/product/classic-balance-ball-chair-leg-extenders/95-1561.html
I purchased the balance board so I could perform physical therapy and build my balance and core at home due to problems caused by multiple sclerosis. It was delivered on time and is exactly what I expected. Thank you Overstock for carrying mobility tools that I've not seen anywhere else.
