Title: Hard to pump up fully
Review: This product came very promptly and was pretty much as described. The only minus is that the ball is somewhat hard to pump up to full tautness, which means that when you sit on it, the ball will sink down a little and make it lower than a standard chair. Other than that it seems to be a good product. My 9-year-old son needs to strengthen his trunk muscles, and he doesn't mind sitting on it when he's using the computer.
