I purchased this Tuff Guard 10 year mattress protector based on the recommendation of overstock when I was purchasing my Sarah Peyton Bed. I've been using it for 7 weeks and I've laundered it once. This cover easily covered my new 14 inch CA King Mattress. It has a material on the underside that works like a plastic barrier (sorry, I'm not looking at the description offered). The top side is a soft terry material. I was concerned that we would feel the plastic like barrier, but to my surprise, we didn't. I expected that maybe a crinkle type noise would be heard when we rolled over, but again, that was not the case at all. Lastly, I have night sweats and thought cover might make it worse, but I'm happy to report, that is not an issue. It claims to be breathable, and I have to say, that seems to be true. So, Pros - plenty big for deep pocket beds Machine Washes and drys great Has kept my bed sweat stain free so far Great price Cons - It might be a little too generous in size if your mattress is not as deep as the 14 inches mine is.
