This seat is beautifully made and does the trick.  I have 2 standard Toto toilets and one Kohler, (all fairly new) and the seat fit was perfect with my elongated toilets and my round one.  I didn’t like any of the typical disability seats on the market, especially since most of them have grab bars which I didn’t need. I simply wanted the height to be higher and more comfortable without looking like an add-on.
