Cheaply made plastic. I put back in the box and will just keep what I have for now. Nothing about this seat makes me eager to install. Guess you need to see and touch before buying.

Exactly the design/ shape we were looking for to go with our Foremost toilet. And it looks fine set at 16” deep (thankfully) as even with tightening the bolts as much as possible it does not maintain its 17.5” depth setting

Great seat for the Price. Hugs Wifeisis bottom Perfect

Did not fit my toilet.
