I haven’t tried it but my husband did. He said it’s fluffy but not very cool. It made him sweat overnight. I expected the pillow to be very nice but doesn’t seem like it. I will try with a silk pillow case to see if that helps.

I'm kinda up in the air about these pillows. They're very fluffy pillows but they're also very firm. I cannot use pillows that are too firm. They just make my neck hurt. However, they do keep you from getting too hot.

At first these feel nice, but go flat within a day or two. They smell terrible. I aired them out for two weeks before sleeping on them. They stilll stink of chemical even after a month.

It's a wonderful pillow!

I did not find this to be cooling when you look inside it's just chopped up foam it did not feel good on my face because it felt lumpy but for the price I wouldn't be bothered to return them. I don't know why they call them gel it was no jail in it I have gel pillows and it is like a liquid and those work great.

I am the person that constantly flips their pillow all night long because I can't sleep if I get too warm and I'm always looking for the cool side to lay my face on. With these pillows you do not need to do that! They are so comfortable. They are supportive yet soft, I can run my arms around one and hug it or I can use it as a regular pillow it's just a really great product. I actually bought eight of them and I'm thinking of buying a couple more just to have on the closet shelves in case company shows up. I would absolutely recommend these and the price is just unbelievable for what you get!

One pillow was heavier then the other. One of the pillows didn't get cool at all. I had to look at the package to make sure I bought the right pillows. I really needed a cooling pillow for the hot flashes but these pillows just made me even hotter. Not a great buy.

I love this pillow! It does exactly what it says. As soon as you lay down, it has a cooling sensation. I love that you can unzip the cover and wash it as frequently as you’d like to. I also love that you can unzip and take out any of the flushness and make it the size that you want. My husband likes a fluffier pillow and I like a flatter pillow. With this pillow we could customize it to however we wanted. It’s really a great pillow and I plan on buying one for each of my kids.

Gotta say the spouse and I are both big fans. We live in Vegas and these pillows have reduced sweating at night and even allowed us to turn the thermostat up a couple degrees saving a fair bit on energy. Will need to see about durability but all good so far.

These pillows are definitely a win in our home. The kids and I LOVE pillows and these hit most all the marks for us. The fabric encasing the pillows is so nice my kids took these and ran with no pillow cases and did not want me to put any on since the pillows felt so nice without cases. The outer shell comes off easily and is zippered. Same as the inner shell. These are adequately stuffed but the inner shell also has a zipper where you could easily open and add more. We all love how the pillows inner is not a solid piece, but many, allowing it to mold around your face and neck. As a side sleeper, I’m totally in love. Thanks for the kiddos they have already been dirty and needed cleaning which was so easy. As a mom I need this convenience and comfort. The only thing we would like is for them to have a bigger size available. But that is not a ding by any means. 5 stars from all three of us.
