It’s pretty good!
Size: Queen (1 Count), Color: Crescent White
It’s okay ig… comes with a TON of stuffing but is removable and it’s got 2 different sides that feel different. One is cooling and one is comfort. It overall good pillow, but nothing special about it fr. Good quality though.

It works! Quality pillow.
Size: Standard (1 Count), Color: Original White (Cooling)
This does actually provide a cooling effect, and it's very comfortable! The accompanying literature is helpful too. I believe this to be a quality pillow for the price.

Most comfortable pillow I’ve ever slept on
Size: Queen (1 Count), Color: Crescent White(cooling)
This is the most comfortable pillow I have ever slept on. It doesn't mash down like other pillows. Cradles my neck perfectly plus it’s cool. I broke my neck a couple of years ago and this pillow feels very good and comfortable. Definitely recommend to everyone. Ive used it since May and it’s retained its shape.

Smell
Size: Queen (2 Count), Color: Original White (Cooling)
The fact that there are not more comments on the smell of these pillows has me worried about some of yall. Listen, I LOVE the weight, and the firmness, it’s perfect for that. However, these pillows are RANK. They have a very strong mildew-ish smell that lingers. I took the outer cover off and washed it and let the pillow air out for a few days, the smell is still very strong when you press your face against it, which one does because it is in fact designed for that purpose. It smells so bad. It’s nauseating. I can smell it through two pillowcases and blanket that I threw on top of them hoping an extra layer would trap the smell. I’ll bake them in the Texas sun tomorrow and hope that helps, because otherwise these are the perfect pillows for someone who wants to feel like they are hugging a torso but can’t stand the sound/feel of someone else breathing. I don’t know…4 stars, if the smell goes away I’ll come back.
Update: many many days later. Either they don’t really smell anymore or I got use to it. They’ve held their firmness and shape well. I like them.
