This $76 stool (plus shipping) is intended to reduce the noise in your bathroom by lessening the height at which the apple juice from lunch hits the megaphone, we mean toilet, below. Though for $76 dollars, you might be able to better insulate your bathroom to eliminate the insult that kneeling creates.
Just in case you'd like to order one today, you can find it in the 2-part polyurethane model (which will run you $20 more), or the 1-piece wooden bench over at the Japan Trend Shop. It's ok, we won't judge you if this is just the item you've been looking for, though we do request you tell us how it worked out. On second thought... scratch that, what happens in the bathroom, stays in the bathroom (no matter how loud it is).
