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!

Cooling fabric is Just what I needed
Color: 03-black, Size: 20" X 26" (Pack of 4)
I'm a hot sleeper. These cooling pillow cases are fantastic. It has ended soaked pillow cases. I paired these with waterproof pillow cases for extra pillow protection. I now sleep cooler and wake up dry. I also toss and turn less and wake up less frequently hot, sweaty and uncomfortable and I can sleep though the night. I don't need to flip my pillows over because of sweat. Both sides of these pillow cases have arc chill cooling fabric. They're soft, silky, breathable and comfortable to lay my head on. The colors to choose from is a wide selection. These look great on my king size bed. I love this fabric so much that I upgraded all of my pillows and blanket sheets to cooling fabric. I'm sold on these. The zipper is premium, sturdy and durable. My pillows fit perfectly on these cases. The cooling material is top notch high quality to me with great craftsmanship. I liked these ones so much that I bought more and plan to again. My partner seen and felt these and immediately went online to buy some blankets to go with the pillow cases I gifted. I also bought my son these and a few cooling blankets. These work best with a fan or air conditioner. Highly recommended and you won't regret this purchase if you're a hot sleeper to profusely sweating during sleep.
