Query: Seems expensive, but the simplicity is worth it.

How can the simplest of potty seats be the most expensive? In this case, you must pay for the simplicity and functionality of this design. We looked at many other potty seats with music, lights, lids, and countless other useless bells and whistles. You would have to clean those things at a car wash to get in all the crevices and moving parts. This seat is stable, simple, and easy to clean - just like the one I had when I was 2. I guess no one but Baby Bjorn thinks simple functionality is the way to go.
