Bests & Worsts Reviews from Amazon

I actually like this cover but I'm giving it 1 star only so anyone who buys it will know that it is not 100% waterproof. That being said, it's pretty darn close to waterproof. Let me explain - my toddler son has been sleeping on it for over a year and during that time, he's had several diaper leaks and they've never made it through this cover. Tonight, however, he truly put this cover to the test. He was sitting in bed and we were getting ready to read a book when he looked at me, gagged, and then projectile vomited (buckets of liquid) all over the bed (and me). He heaved 4x and he had a lot to drink tonight so it was literally like inches of liquid pooled up between us in the bed. He looked at me and said "Mommy, we're in water." After my husband got him in the shower, I pulled the cover back (carefully making sure all the liquid stayed in it) and there was a small wet spot about the size of a dollar bill on the mattress below. Now given the sheer volume of the liquid that sat on this cover, I am not shocked that some of it made it through. But the amount that made it through was very, very light and easy to clean (compared to how much was on top of the cover). So this review is just an FYI. The cover is great and probably as waterproof as you can get without putting plastic on the bed. It is not, however, 100% waterproof.
