good product
I have a tile seat in my shower that is very cold and hard to sit on.  I tried a blow-up style cushion, but it would never stay put even with suction cups on the bottom.  This is a heavy-duty foam style, not like a sponge, its much firmer than that, and it doesn't hold water, so you don't have to wring it out, just let it dry.  It is very comfortable, doesn't move around and has raised bumps on one side that prevents mold or mildew from growing underneath it.  It's very handy to have if you need to sit for any reason during a shower.
