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.

Awful, very soft not firm at all
Color: White, Size: Standard/Queen, Color: White, Size: Standard/Queen
Ordered the Serta Ocean Breeze Breathable Medium/Firm Bed Pillow. The listing is misleading—it shows two pillows in the photo, but only one is included for the $47.00 price. The pillow arrived vacuum-packed and was extremely flat. Despite efforts, I couldn't fluff it back to a usable thickness; the total loft was only about 4 inches. Very disappointed with the quality and presentation. Returned item.
