Way fluffy, good support
Size: Sapphire Queen
This pillow is way fluffy. It does fit into a standard pillowcase with a little tugging and stuffing. Worth it though, as it’s cool and provides more support than a usual side sleeper pillow. I’m not using the extra stuffing that comes with it as the firmness is fine for me right out of the box.

Great for side sleeper
Size: Sapphire King
I am loving this pillow. I waited a few months to see how I would feel about it, because I definitely did not like solid foam pillows previously. I’m a side sleeper, and my pillows were discontinued from a different bedding company. I tried a few others in the interim and was not happy with the support for my neck. Tried this one and I really love the shredded foam. It supports my neck and my head, it’s comfortable. It is movable if I need support in a certain position. It has extra fill if needed. Super happy with this purchase.

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
