    Great pillow for side sleepers!
    Size: Standard 20"x28", Number of Items: 2
    I bought these pillows at first because I wanted to try out the “coolness” of them (I live in a place with no AC). They’re definitely not cold, but they do a good job of regulating the heat on particularly hot/stuffy nights. But my favorite thing about these by far is the support! I’m a side sleeper, and these are just the right amount of firm to tuck between your shoulder and neck that keeps your neck in a good position all night, while still soft and comfy for your head! I’ve been sleeping on them for about 2 months now and they have maintained their shape really well. Definitely recommend!

    Great Pillow with Minor Inconvenience
    Size: Body 20"x54", Number of Items: 1
    When i got this pillow I wasn't sure if I was going to like it or not. It is not inherently lumpy like I thought it was going to be. It molds to you as you use it every night but resets as memory foam is meant to. My only issue with it is when it is packaged thru gold the pillow in half then roll it and vacuum seal it. Where that fold was there is a lot less fluff and no matter what I do I cannot seem to redistribute the fluff to even it out. Otherwise it's a great body pillow Edit: Still can't get the fold out if the pillow no matter what i do but I still really like the pillow. My mother just got the same one and she does not have any issues with the fold line. I am keeping my review as 4 stars but it really is an awesome pillow

    I Sleep Hot and This Is The Only Pillow Ive Tried that Stays Cool!
    Size: Queen 20"x30", Number of Items: 1
    We have a closet full of pillows. I have tried a bunch from cheap to expensive, Sleep Number to Kohls. I sleep really hot, but I bought this pillow and it is crazy how cool it feels. If I get too warm and want it cooler I flip it over. I was doubtful but now Im sold. I winter in Arizona and Im buying one of these for out there as well. It's firm but fluffy soft. Great support for a side or back sleeper. Maintains its shape, the filling is cut up foam pieces of some sort but its super comfortable. I have not washed it as it had no foam odor, and I was able to use it right away. I definitely recommend this. Great pillow!

    Forget the traditional big pregnancy pillows, get one of these!
    Size: Body 20"x54", Number of Items: 1
    I’m in the 2nd trimester of pregnancy and I’m having a hard time getting comfortable in bed or waking up without pain. I got a big U-Shaped pregnancy pillow but it was awful. It was fluffy, but offered 0 support and firmness. Also the stuffing made me so hot! I decided to try this and I’m soooo glad I did! The memory foam means it actually has some support and firmness to it and it stays pretty cool. It is heavy, but it’s worth it. I put it between my legs and hug the pillow with a 2nd pillow behind my back for extra support. I can ACTUALLY sleep in my bed again! And I don’t wake up with pain and stiffness. Highly recommend if the traditional pregnancy pillow isn’t working for you. Make sure you let the foam rise for 72hrs. Apparently there may be an odor after opening it, but I haven’t noticed anything or it already dissipated. (I also didn’t actually wait the 72hrs but had no issues)

    Very soft and squishy vs supportive
    Size: Queen 20"x30", Number of Items: 2
    These have really nice cooling fabric on one side. The other is a soft cottony fabric. They are very squishy. Not firm at all. I prefer a thicker supportive pillow that doesn’t completely collapse when you lay your head on it. I chose to purchase additional gel infused memory foam shreds to add stuffing to the pillows. I used a five pound bag of the shreds between the four new pillows I bought. I wish that wasn’t necessary. I did end up with nice , cooling, supportive pillows in the end though.
