I recently replaced a toilet seat in my house.

But the new one tends to slip a lot - VERY awkward to be sitting on a
slipping and shifting seat, obviously.

I'm pretty strong and have hand-tightened the bolts as much as I think
is reasonable, and the bottom line is that, subjected to the forces of
use, this seat continues to slide.

So I'm wondering if they make rubber washers or gaskets that fit between
the actual toilet fixture and the plastic parts that hold the bolts -
just something to take friction out of the equation.

And if not that, short of tightening the bolts more (they're as
hand-tight as I can get them) or getting a new toilet seat (seems
excessive), what else could be done to prevent the seat from slipping?

My experience, a combination of the holes in the porcelain being
deliberately large, plus the bolts working loose because the nuts don't
have a lot of grip on the porcelain.... the various fixes I've seen
both on new seats and on old toidy's I've taken apart include the
"sticky pad" methods described in the thread, as well as tapered
conical washers that force the bolts to center in the holes; looks like
maybe something like conical faucet washers might do it; to indeed,
filling the holes with putty before tightening it all up.
