The description is misleading. Yes, it's waterproof, however, there is no "cushy padding". It's just a layer of very thin synthetic plush fabric on top of the waterproof layer that feels tacky, to be honest, and doesn't soak up anything. In fact, it makes for a sweaty behind because there is no layer in between and the child is sitting pretty much on plastic. I only use it when I know my little one might fall asleep.
