Totally worth the money
Size: King (Pack of 1), Size: King (Pack of 1)
Right off the bat, the packaging is absolutely adorable and felt like I was buying a premium product. I love that this pillow is adjustable and as a side sleeper, I needed a pillow that is both firm and supportive of my neck. This hits all the boxes. We will be buying more of these for our bed!

Super Comfortable and Cooling Pillow!
Color: Blue, Size: Standard
I’ve been using this pillow for a few days now and I really love it! The cooling gel side feels amazing and stays cool during the night. The memory foam is soft but still supportive for my neck and shoulders. I wake up feeling much more rested and without neck stiffness. The quality is excellent and the cover is very soft and easy to clean. Definitely worth the purchase!

Perfection!
Color: Blue, Size: Standard
This pillow is so good! Perfect firmness and enough support. It’s very comfortable and does help with sleep especially on hot nights! The cooling gel does a great job of keeping the pillow cooler. It’s a good size pillow for a twin bed. I also like that it can be very compact when taking with you, the memory foam compresses very easily and fluffs back up quickly, so it’s very adjustable. Great value for the money! I definitely recommend!

Good pillow that becomes warm faster than competitors
Color: Blue, Size: Standard
I have bought several cooling gel pillows and am quite happy with this one with one caveat, that it doesn't retain coolness as long as other cooling pillows like my sealy that fell apart. Now, a cooling pillow will never retain coolness indefinitely, neither will a normal pillow, but this one tends to become just a normal gel warmth about 30 minutes before my old Sealy so I can't give it a full recommendation. It does however seem to be a nice pillow otherwise with a nice supportive firmness and provides a nice sleeping experience as a pillow, and when it's cool it's quite cool. It holds up the coolness for about an hour while sleeping in a case normally and maybe close to two hours when I have the AC on.
