You won't see it until you start cutting i to the floor. The foam is in areas that aren't accessible through and lids or compartments.
Some pedestals have a center protrusion that requires a small hole cut out under them. The ones where the pole is part of the seat, and needs to slide down into the base. If you have that style, you would see the foam when you pull the base off.
Sorry, I derailed the thread a bit with my short guy talk. Luckily, I can just hide behind someone bigger until it blows over
