The size is regular, and the pattern is monotone penguins. My child is just one year old and it's still usable, but they've started to dislike it, so I'm selling it. It was used quite frequently for a while, so please check the photos for any stains, etc. Also, since it is a used item, please refrain from purchasing if you are sensitive to such things.
