You want open cell foam. Never rely on an LLM getting the facts right.

Of course. So-called AI is worth no more than any random person's
comment and we know how often they are wrong, but I wanted another
opinion.

Most rubber formulations are slightly denser than water. However open
cell foam may retain sufficient air to reduce the average density to
less than that of water. If that turns out to be a problem try
attaching the foam to something such as a rubber anti-skid mat.

Have you considered using a folded up towel?

What a great idea! Not to take away from you and your truly great idea,
I did think of that a couple days later, and I tried it. it workded
fine. I took the towel out of the water before draining the tub, let it
drain on the side of the tub for a a half-day, then threw it over the
shower rod for another day. Took only a day and a half to dry and
doesn't seem dirty at all.

I've also put more towels on my desk chair, which doesn't get wet or
have to be dried. If I'd known the problems of losing weigh, I might
have been mmore successful in not gaining weight/
