    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!

    Deserves more Stars
    Size: Queen
    I was very hesitant to make a pillow purchase off Amazon. Turns out it’s the very best purchase! I had chronic neck issues the chiropractor couldn’t resolve. It was the first time, I had an unsolvable issue. I finally decided to spend the money and buy new pillows. My neck issue was 95% resolved the next morning. I’m not kidding! It’s now 100% resolved after a very short period of time. They are a wonderful gift to myself.! quality is top-notch. The support is fantastic. They adjustability is phenomenal and you can adjust the firmness because they give you extra foam. They’re completely worth every penny. I’m 61 years old, 100 pounds and very active. Waking up with neck strain was horrible.

    I Hit It With the Dryer and It Became a Real Pillow!
    Size: Queen
    This DreamyBlue Moon Pillow made a much better first impression than I expected. Out of the package it looked like it needed a pep talk, so I threw it in the dryer to fluff it up and it came back with purpose. Just full on BAM. Pillow achieved. The shape is one of the best parts. It actually feels like a pillow that wants to do its job right. Not too weird, not awkwardly bulky, not one of those ones that looks promising until you lay down and realize your head is now parked on a bag of chopped foam and bad decisions. I also really liked being able to customize it. That part matters more than people think. Pillows are weirdly personal, and most of them give you exactly one option: deal with it. This one lets you adjust the fill until it actually feels right, which is a whole lot better than waking up annoyed and pretending it is fine. And for anyone wondering, mine did not have any weird smell. No chemical funk. No “maybe this needs to live on the porch for a day” situation. It just fluffed up, felt good, and got to work. Overall, this has been a solid win. Comfortable shape, easy to adjust, and none of the usual nonsense. Which, for a pillow, is honestly a strong performance.
