I bought this waterproof mattress pad to protect my toddler's twin mattress. I ran it through the wash with no problem, it didn't rip. And it fits the mattress well. It was a great price too! We're very happy with it. A plus is that it's soft on the top so it adds a tiny padding to the bed, and doesn't have a plastic feel or sound as you lie on it.
Doesn't stay in place on mattress. Keeps bunching up/wrinkling under fitted sheet making night's sleep uncomfortable Never had this happen with any other mattress pad I've purchased in fifty years.
