Great product! I love the feel of these.
Size: Queen, Color: White
“I recently purchased the Serta Power Chill Cooling Pillow Protectors, and they have been a game-changer for my sleep comfort. These pillow protectors have exceeded my expectations in several ways. First and foremost, the cooling technology is fantastic. I tend to sleep hot, especially during the summer months, and these pillow protectors have made a noticeable difference. They keep my pillows cool and comfortable throughout the night, which has led to more restful and uninterrupted sleep. The fit is also excellent. They easily slip over my standard-sized pillows and stay securely in place without any annoying bunching, wrinkles or slipping during the night. And the zipper is amazing. Having no wrinkles in my cover is easier on my hair. What’s great about these protectors is that they not only keep my pillows cool but also protect them from spills, stains, and allergens. It gives me peace of mind knowing that my pillows are safeguarded while I enjoy a cool and refreshing sleep environment. There is no noise when sleeping on this cover, it’s soft. Cleaning is a breeze. They are machine-washable and maintain their cooling properties even after multiple washes. The quality of the materials used is evident. These protectors feel durable and well-made, promising long-lasting use. While they are slightly more expensive than basic pillow protectors, the added cooling benefits and protection they offer are well worth the investment. They’ve made a significant difference in my sleep quality, and I highly recommend the Serta Power Chill Cooling Pillow Protectors to anyone seeking a cooler and more comfortable night’s sleep.”

Loose on standard pillow.
Size: Queen, Color: White
Too large for standard pillow. It would fit a queen size pillow much better. It does stay cool.

Soft and cool. Very cool. 🧊
Size: Queen, Color: White
I bought these for my memory foam pillow and they’re excellent for cooling it. I use 2 of these on the pillow for maximum chill factor and it works. They’re very soft, the zippers are high quality. Easy to put on with a bit of stretch- generously sized. They’re stain resistant. I’m glad they’re NOT waterproof because they’d be too hot then. They’re very durable. Wash on delicate setting in a mesh bag and air dry and they last long. They’re very quiet- smooth and silky. Definitely recommend!

Cool enough
Size: Queen, Color: White, Size: Queen, Color: White
I thought I had purchased pillows so when I received these I was a little disappointed. However that was 100% on me for not reading the listing and just trusting my search. I decided to give them a try and so far they seem ok. They don’t stay cool even though I have them on cooling pillows. They are super thin but very soft. They fit on my pillows perfectly. I don’t think it has improved my sleep quality but it hasn’t made it any worse either. I don’t think they are waterproof but I don’t really want to test that. I like that the zipper is small and seems to be decent quality. Smelled heavily of chemicals when I first took it out of the package but that disappeared after a few minutes.
