Not cooling
Size: Sapphire Queen
We have waited to give a review. These 2 pillows we purchased based off the good reviews and that it states has cooling effect.
Well a good point it has is the blend of stuffing. Also the ability to remove or add for your comfort. The softness/firmness is just right once you figure out your comfortable mix.
However with having foam and poly blend, there is no cooling. Those tiny blue specs do nothing but add color to stuffing. Both my husband an myself wake up because our head is hot. Moving around alot helps with that but doesn't offer a restful sleep.
I do like that it has a cover over the pillow so you have 2 zippers to go through to remove stuffing. This prevents waking with foam all over your bed.
Overall I would have given a better review if actually offered the cooling effect. I could have saved money an just purchased the cheaper pillow they offer.

Tired of bad sleep try this pillow :)
Size: Sapphire Queen
Never owned a nice or expensive pillow finally after a good 25 years of super cheap pillows finally decided to try a nice one and see if there is a big difference and see what all the woot is about anyways in my opinion I am a side sleeper and I now just use this instead of multiple pillows and I can safely say it works very well seems too cool a little and is very comfortable plus bonus they give you extra fluff if you want to add more or replace but straight out of the box was absolutely perfect for sleeping I am insanely picky about it will ABSOLUTELY BUY THIS AGAIN 🥰🥰🥰 firmness absolutely perfect as is

Flattened out a little over a month or using it
Size: Sapphire Queen
Figured I would wait a month or 2 before leaving a review. At first. The pillow was great. Very comfortable. Held up nice. Nice and firm and gave great support. After a month. It started to flatten out. Had to re-fluff it only to have flatted out faster this time. Now no matter how many times I fluff it. It doesn’t give the proper support any longer. I’ve bought 2 of these and they are identical. So it can’t be just a fluke for the 2 i have. I’m regretting the purchase as the price was fair when I bought them. But not any longer as they are not the same.

Best pillow ever!!!
Size: Sapphire Queen
I have actually tried dozens and dozens of pillows in my life, and dozens in the past three years, but this is it. Some cheap, some very very expensive, and some very famous brands. This one beats them all. So awesome and comfortable (side sleeper). I tried one and loved it so much I ordered a second right away. It is exactly what I've been searching for forever!!!
Stays in shape, extremely comfortable. Only thing is you definitely need a 32" pillowcase to cover it, and I wish they made a 34" pillowcase, but no luck. I used the pillow the same night and it's definitely worth the money.
No neck pain, super squishy but supportive, and no odor.
