For optimal performance, it may be necessary to re-inflate your new Balance Ball once or twice after the initial inflation. Once your chair is assembled and the Balance Ball is inflated, re-check the ball size the next day. If necessary, add additional air and check once more the following day. Your new Balance Ball may need a day or two to "stretch" to its final size (which should then fit perfectly in the base).
