Which toilet seat with soft-close function?

Well… the general contractor installed their own house brand. How I found out today! (because of the research) it seems to be a Geberit. Now I just landed in the shop of calmwaters… they have a configurator there, the entered measurements result in a seat. Seems to be a private label as well. Because the original from Geberit looks exactly like that. Also about a 4cm thick (lid) rim. Geberit Renova Plan… that’s what it looks like.

I wonder, for example, if the glasses are flush with the edge or if they can also have an overhang?!

Can have, yes. If it doesn’t bother you, yes.

What one can occupy oneself with. Who should be bothered if the locus seat protrudes over the key edge? Too small might be dumb, yes... but too big?
