This would have been a 5 star rating, but the mattress cover really shifts around at night and must be repositioned every day.  I do like the fabric, it's very soft. There is no bothersome crackling noise that sometimes happens with waterproof pads.  The cover is designed to fit nicely on deep mattresses.   so-5 stars for being soft and waterproof, but 4 stars for putting the cover back in place every day.  Still a good buy.
