It took me a while to even find this style. As you know, most mattress pads have that all around elastic that keeps riding up sooner or later, or shift out of place. This pad actually stays in place. It's been 2 weeks & so far so good. It's firmer than I expected. I would have given it 5 stars, but it feels a bit lumpy in places & my biggest fear is, what's going to happen after the first wash. Will it get more lumpy? I don't know. My main goal was to get rid of a runaway pad & I've succeeded. If you have the same problem, this should be a very inexpensive fix.
