Weird smell
Color: White-cooling Basic, Size: Queen(Pack of 2)
The pillows are great for someone looking for something cool and comfortable. We loved them so much that we bought a second pair. However, we were seriously disappointed with the odor of our last purchase. They give off a strong and indescribable chemical/burning plastic smell so nauseating that it’s difficult to sleep with. We’re hoping this issue will resolve with a couple more washes of the pillow cases, but am worried the source is the stuffing itself.

helped treat my sore neck
Color: White-cooling Basic, Size: Camping Pillow(Pack of 1)
This pillow — after dialing in the right amount of shredded foam — has greatly helped my sore neck. Initially, I had to remove some foam. Then I gradually added foam until it reached optimum comfort and support.
It is also CPAP-friendly — especially when I position my head near the pillow's edge. (I am a left-side sleeper.)
I like the travel size because I use a bulky hugging pillow to ease stress on my shoulder and elbow. That makes my side of the bed feel cramped if using a larger head pillow. A smaller pillow is easy to flip end-to-end in the middle of the night.
I have spent lots of money on pillows over the years, but this is the best I've ever had for relieving [1] neck pain and [2] CPAP mask seal problems. Very comfortable, supportive, and affordable.
I did not notice any unpleasant smell — and I am usually sensitive to that kind of thing.
Would highly recommend.

Love them!
Color: White-cooling Basic, Size: Queen(Pack of 2)
Love them! After 10 years with our MyPillows, they finally lost their fluff. The reviews I read of the MyPillows of today were not good; they didn’t have as much filling as they used to. These pillows remind me of how fluffy our new MyPillows were 10 years ago!! You sink right into them and can mush them however and they stay. These are way cheaper than the Coop and it’s the same concept; add or remove the filling as needed. The cooling side is a huge plus too! You won’t be disappointed with these pillows!

super smooth, silky, stays comfortable feeling. DO NOT DRY or wash with heat
Color: Blue, Size: Queen (U.S. Standard), Set name: Stretchy and Soft, Color: Blue, Size: Queen (U.S. Standard), Set name: Stretchy and Soft
I'm impressed. I have used cooling pillow cases before, and found them effective, but the cooling material have always been on just one side. These are 100% cooling material. The material is super smooth and silky feeling. It is great feeling against hair and skin (even better than my old polyester satin I was using before cooling pillowcases). The material is cool, and does not seem to get hot hot. The pillow cases are super stretchy with a small hidden zipper. They grab onto the pillow and dont loosen up. Makes my pillow look neat and clean, not sloppy from loose material. I can even have two pillows stacked and somehow despite being a smooth material, the pillows dont just slide off each other.
The cooling aspect works by not trapping heat, not allowing heat to get to the pillow and hold it there. So yeh, the pillow case will feel warm eventually but if you have a fan, or AC, or flip the pillow, then it is is truly cool. Otherwise in my experience when I use a pillow without this, the pillow just gets hot, stays hot, and even with flipping it feels hot.. because the pillow itself has trapped the heat for remainder of night. Yuck.
One thing to know and this is very important-- as I learned the hard way-- DO NOT DRY IN DRYER. DO NOT WASH IN HOT WATER. Heat will destroy the material ability to feel and stay cool. Do you want a regular heat trapping pillow case? Then go ahead and dry these in the dryer a few times and you will have a regular pillow case. HOw do I know? I bought these to replace another set (different brand, same idea, same instructions that I failed to remember). I always dried them in the dryer, and one night after having gloriously cool pillows, I noticed that my pillow was HOT night after night. It was then when looking for another set of pillow cases that I learned that they cant be exposed to heat like that. SO PLEASE, just AIR DRY.
And so, after I got these and put them on my pillows, I had a much better nights rest. I remember thinking that I wasnt waking to rearrange my pillows. They were just comfortable all night long. Sure, I'd love an even colder pillow, but our room is on the warm side. But at least I wasnt noting the hot hot pillows anymore.
