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.

Great pillow!
Size: Queen (Pack of 2)
They were a gift for my daughter and she loves them! She says they are comfortable and "squishy" and she sleeps better on them.
