Serta Power Chill King Size Waterproof Mattress Cover, Soft and Breathable Cooling Mattress Protector, 15" Elastic Deep Pocket for Secure Fit, White

Good waterproof cover, still feels a bit plasticky on the mattress, it as bad as others, had to order a second one because it got destroyed when I washed it, despite following the instructions to a T it came out with the waterproof membrane peeling off

I bought this and put it on my bed 4 nights ago. This photo shows my skin temp from my phone app. I was waking up during the night and every morning, covered in sweat. It was really affecting my sleep quality. I love my memory foam mattress for it's amazing comfort, but it retains so much heat. You wouldn't think 1.5 degrees would make much of a difference, but I am telling you--I don't wake up sweating, and I'm sleeping better. My only regret is not buying this sooner.

Maybe my expectations were a little too high. But I feel like I still radiate the same amount as I did with my other non-cooling mattress cover. I do feel like if I move into a new spot it does feel maybe slightly cooler but not significantly. Otherwise fits well on our king and washes nicely.

THIS IS MY 5TH SERTA MATTRESS PROTECTOR, I HAVE ONE ON ALL 4 BEDS IN THE HOUSE. I BOUGHT 2 FOR MY SON THAT WETS THE BED, FOR MIDDLE OF THE NIGHT SHEET CHANGES.IF YOU HAVE BEDWETTERS THESE ARE MUST HAVES. NOT ONE DROP WILL LEAK THROUGH, WHICH IS NOT THE CASE WITH OTHER BRANDS. I THINK I'VE TRIED THEM ALL, THE ONLY OTHER ONE THAT WORKED FOR NO LEAK THROUGH WAS $300+. THIS MATTRESS PROTECTOR IS A MUCH CHEAPER OPTION, COMFORTABLE AND DURABLE.

This isn't a miracle mattress protector that keeps your bed cold all night. It does how ever feel cool when you first get into your bed.
