I like this one because it is sturdy enough to toss in the wash (unlike the cheaper ones that are spot-clean only with damp cloth), and it provides complete coverage for the mattress. I keep an extra one on hand, so that I can change the sheets in the middle of the night if needed, for those night-time accidents.

...my cat makes little booboo's. Sheets and bedding are easy to clean, mattresses not so much. These covers keeps them safe.

Does what it's supposed to..,

I added complete details but the form is not allowing me to submit review so removed everything. The product is not waterproof.

Not a good product

I was expecting a bed sheet look/feel-like product with water proofing, but it is basically a giant plastic shower cap. I just don't think the quality of this product justifies the price, so I returned it.

Basically a giant plastic shower cap

I bought this less than a month ago and I never sweat at night but since I've had this mattress protector is has caused myself and my boyfriend to sweat at night. What is equally as annoying is, how it continually slips off the corners of the bed and has to be fixed on a daily basis. We will be exchanging this for a different mattress protector.

Makes you sweat and continues to slip off corners

I bought this a few months back.... Waste of money. I wake up every morning with my bed wet from sweat. I am not a night sweater what-so-ever.  Took it off my mattress and the problem was resolved.  Big mistake to buy.  Don't recommend at all.  Not even something I'd feel good about donating.

Doesn't breath.

Within the first night of using this mattress protector my 2.5 year old had an allergic reaction and woke up with hives. This product is also very cheaply made (understandable given the price) as it crinkles every time you move in the bed. Also, this product does not allow any air flow and is not breathable; you will become very hot quickly.

Don't buy

I purchased three of these. The plastic separates from the zipper, and rips easily.  They are bad quality. They only lasted briefly. Not worth purchasing, or the effort to put them on your mattresses.

Rips easily

Doesnt Breath

My 3 year old woke up every hour for 4 nights crying with night sweats before we figured out it was this cover. Stay away.
