Soft and cooling
I needed a new mattress pad and this one really is cooling. It got my king sized mattress so well. It's super soft and comfortable. It washes well also. I definitely recommend it.

So Comfortable and Actually Feels Cooler
I bought this mattress protector for my queen bed because I tend to get hot at night, and I’ve honestly been really happy with it. The first night I used it, I noticed that my bed still felt cool and comfortable instead of getting warm and stuffy. I also like that I can’t really hear or feel the protector underneath my sheets. It fits my mattress well and has held up nicely after washing. It’s such a simple thing, but it has made my bed feel more comfortable, and I’m really glad I bought it!

Comfortable and Keeps the Bed Feeling Cool
I’ve been really happy with this mattress protector. It fits my king-size mattress nicely and doesn’t make the bed feel bulky or noisy. I was especially impressed with how comfortable and cool it feels—I don’t notice that extra warm feeling some mattress protectors can have. It has also held up well after washing and still looks and feels great. Definitely a worthwhile purchase and I would buy it again.

Soft Cozy and Great Protection
Really happy with this mattress protector it fits the mattress nicely and feels soft and comfortable without making the bed feel bulky I love that it has a cooling feel especially at night and it helps keep the mattress protected while still keeping the bed comfortable my 12 year old says her bed feels fresh and cozy and I love the extra peace of mind knowing the mattress has an added layer of protection

Tampax would be proud
I wish i was able to actually grab the fabric to tell if this was going to give me a diaper bed or not. As soon as I opened it, it went right back in the bag to be returned. Some of us don't want to sleep on a bed with a teenagers panty-liner on our mattress.

This is a decent mattress cover, but the top that is plastic fills a little cheap for the price you pay.

Cooling mattress cover
Does as it says and offers a cooling affect. I need the waterproof advantage because my 17 year-old dog sleeps on my bed.

LOL 100% agree with the person who called this a diaper bed. My boyfriend also called it hospital bed as soon as we put it on so it’s quite funny to see that as well. Pretty terrible of a product actually..

I didn’t sleep with it to know if it is cooling but it didn’t feel like it would be when I held it in my hands. As I unfolded it, it was so loud, I thought maybe it would be better stretched out so I placed it on my bed. It was still very loud, like crinkling plastic.

Effective, Good Quality
I bought two mattress pads before this that were waterproof and made a kind of crinkly sound that I couldn't stand. this one is quiet and I do feel it disperses my heat effectively. It isn't perfect but I will give it a four stars for making somewhat of a difference so that the heat does not build up for my memory foam mattress. It does fit well. it has a lot of stretchiness and can easily tuck under your mattress to get a lot tighter. if needn't be. I do recommend this mattress pad as an affordable option to give you a little more cooling at night than if you did not have it!

Highway robbery for low quality.
This is a single layer of synthetic fabric over a single layer of plastic tarp. Yuck. Immediate return. So disappointed they would even sell this. At least make a little effort.

One night with it and it was okay-ish. Made my soft sheets feel scratchy somehow. Had to return it cause of that. Not to mention the nosiness.

Diaper bed
Be ready to feel like your sleeping on a diaper. Sounds like a hospital bed and was ruined after the first wash. Taking it back

returning. I should have read reviews. as soon as I pulled it out if the box I knew it's claim to be "audibly quiet" was false. purchased for my son who is a sweaty sleeper. I might as well wrap him in plastic wrap as it's just a fabric lined tarp (a very well made tarp!)

NOT Waterproof as advertised
Be warned, although it advertises that it's waterproof, it is NOT! We have a child who will occasionlly wet the bed and thank goodness we put another waterproof mattress protector under this one because it soaked right through and would have ruined the mattress.

Waste of money.
THIS IS NOT WATERPROOF. I got this because my baby is still having accidents as we transition thru potty training, and the first pee it went completely thru and onto the bed. Second to that IT IS NOT COOLING, you will sweat overnight so much you will think you started menopause , you will think that Florida humidity is not so bad. And so far as the noise I expected some tbh and it’s not as bad as other mattress covers but I can’t tell you why that would matter since it’s not waterproof.

The box says this mattress protector is audibly quiet, but it is NOT quiet at all. It sounds like you’re rolling around on paper. Reminds me of sitting on a table at a doctors office.

Cooling is deceptive
If you’re a hot sleeper looking for protection that’s still breathable, I would not recommend this. I would wake up in the middle of the night sweating. It does kinda feel like sleeping in a tarp. The top layer is pretty slippery and because of its lack of traction would the cause our regular sheets to move and come undone at the edges. Had to return and bought something else.
