I purchased this mattress pad for my potty-training daughter, and it has worked out beautifully! Her mattress is extra-thick and this pad has no trouble fitting it. The material is very nice, and is holding up much better than the traditional vinyl-backed mattress pads, which tend to tear or melt in the dryer. It's also very soft and quiet in contrast with the vinyl pads. My daughter's pad has been washed and dryed quite frequently and is still in as great a shape as it was when I first bought it! And with all of my daughter's accidents, her mattress has never gotten wet. This is an outstanding mattress pad and a great value through Overstock. I highly recommend!
