Just saw a maxipad commercial advertising its product as "feels like memory foam." As someone about to lay his head on a memory foam mattress, I didn't need to hear that.
Why not, Kevin? It's just blood going onto that memory-foam-like maxi pad. Blood, and gooey tissue, and sometimes these clotted blood things that kind of look like if you squeezed them, they'd feel like that foamy slime stuff that kids play with, but you don't squeeze them because they're made up of blood and the stuff that lines the uterus. Why would that be a problem to associate with your memory foam mattress?
Hopefully it will work out in your favor.
