Very impress with the fast delivery of this product. Especially during the crazy winter weather in the midwest. Very light weight. Doesn't seem to be water proof. Fits perfectly with the DaVinci Emily Mini 2-1 Convertible Crib. Haven't used it yet because baby isn't here yet but I feel like it's not firm enough for me. We shall see how it goes. Might write another review after we actually use it.
