I had a customer show me these the other day and I couldn't believe it. It was quite obviously just wadding/cushion filling stuffed inside. Also you will still need a cover to go over the top to stop leaks so try to find ones that aren't pvc as they aren't breathable and cause nappy rash.

What an interesting thought that they are crearted to give mcn a bad rep! Exactly what I said to DH when I saw them esp as they are only $6. I have already had people say how expensive our are when you can get them for $6!
