Leaks right thru. Liquid goes right thru. It is not waterproof. I have used these for some time but i got new one in an it leaked terrible. I ordered another one becasue i thought maybe I just go bad one but the second one did same thing. They are not what they use to be. Do not waste your money if you want to protect you mattress.

I was worried that I would not be able to put this on by myself but the zipper opening was nice and big. No problem getting this on and zipped quickly by myself.

This product is so easy to launder. I don't have to wash it alone, goes right in with load of sheets. Super quiet unlike others. Love!!! that it covers the entire mattress. So much better than the one that came with our new mattress. We'll be purchasing more. Great brand.

The king size is too small. Miserable to get this on a king, 2 hours of labor to get it on and zip it up. One sipper pull instead of two. Zipper pull is too small, excess unfinished fabric on edge gets caught in zipper. So tight a fit tow people had to pull the edges together while one zipped. Unfortunate as 2" of fabric and a double pull zipper would have saved so much labor, cut hands, and misery. I've installed 15 or so of these covers over the years, this is the worst one I have ever used.

This is exactly what I was looking for. Just got a new mattress not long ago, and wanted to protect it on the bottom also, as I don't use a box spring with it.The mattress fit in it perfectly. Took 2 of us to get it on a full mattress, but it was worth the struggle.

It protects my mattress very well

Do not purchase. It is. It “water proof”. My 2 year old had an accident (which is why we purchased this to protect the bed) and it went completely through the protector. It's very thing and plastic sound is loud at night. Worse ever!

Love it! I bought almost a year ago and it protects from stains! My dogs peed on my bed a couple of times and it doesn't stain the cover! Now that's what you call waterproof! I have a Casper king size bed and fits perfectly!

I was able to install the mattress protector by myself (not easy, but I have no help). Love the overall protection but not real happy with the slippery surface. Sheets tend to slip off the corners more.

I placed a cloth mattress cover on top of this one because the sheets would slide and wrinkle on the slick plastic-like finish. I feel confident mattress is fully protected!
