After using this pad for a few weeks, it's held up wonderfully so far. Compared to several other mattress pads that I've tried, this has been my best experience. Waterproofing the mattress is definitely what this is good at, since it held up with a few accidents with a water bottle and juice, and there are zero stains or the least bit of damping from it all. And washing the pad is another bonus, it is very easy to keep clean and retains its texture and shape with no problems. When you put it on, it's a really good, firm fit without any excess "hang" to deal with, and it retains its shape long as you keep it on. My mattress is pretty thick (24 inches), and it fit it perfectly. Overall, this is a good quality mattress pad that handles moisture quite well, and with extremely easy maintenance to it. Highly recommended for what it's really good at. Just a forewarning, this will not protect the sides. It'll only cover the top part.
