I purchased the Hy-ten seat a couple of months ago. After several hip surgeries, and no longer using a raised seat with bars, I still felt that an added height would be an asset. This seat fits our existing Kohler toilet well. There is no slippage on the toilet base, as I experienced with the typical raised seat. It is comfortable to use. And visually, it does not look like an oddball addition. I fits well, and looks good.
