I ordered these for my son who has neck issues and has gone through so many pillows trying to find one that he liked. They’re heavy, so i was worried that they might be “too” heavy to be able to sleep on comfortably, so I ordered a second set, one firmer than the other (just in case) and gave him a set for Xmas and he loved the first set so much without even trying the less firm ones.He also needs the cooling factor and these offered that, too. They are filled with pieces of memory foam (tons of it) and each pillow can be modified by removing some of the foam. The covers are beautiful, high quality fabric with a zipper so ts easy to remove or replace the foam pieces. The size is perfect and they keep their shape. I kept the second set i ordered rather than returning them and i love the pillows. I actually modified two by removing some of the foam pieces. I kept the foam pieces in a zippered pillow protector and i can always adjust mine when or if i need to. 1000% love these.

The Perfect Firm Pillow l

Size: Queen (1 Count), Color: Original White (Cooling)

It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then. They both needed a firm pillow that is not super soft, firm but not achy. Finally found the perfect one.

Comfortable and stays cool

Color: White-cooling Basic, Size: Queen(Pack of 1)

Great pillow. When i opened it, i noticed a strange smell, i assumed its the smell of whatever they use to make the pillow stay cool. You have to fluff it for a good amount of time to make sure the cooling agent spreads well in the foam. Is what i assumed atleast. Its a perfect amount of softness for me. Pair it with some bamboo pillow cases and you got a good night of sleep

Comfortable and Supportive, but Adjust the Filling

Color: White-cooling Basic, Size: Queen(Pack of 2), Color: White-cooling Basic, Size: Queen(Pack of 2)

I’m very happy with this pillow. The size is big and it feels soft while still providing good support, perfect for midnight scrolling on TikTok. One thing to keep in mind is that it can feel a little too tall if you use all of the filling that comes with it. The good news is that you can easily adjust the amount of filling to find the height that works best for your sleeping position. Once I customized it, it was much more comfortable. Overall, great quality, comfortable, and worth the purchase.
