Bought 2 of these pillows, and I can honestly say that they do not stay cool forever. You get like 60 seconds of cool. It does get re-cooled quickly but it’s not called the “60seconds of Cool Pillow” it’s calls “Forever Cool”. It does have a pretty great memory foam core which is why it got 3 stars and I didn’t return them.

The pillow is really firm and does not stay cool, it feels cool to the touch but loses that cool feel quickly.

Pillow picks up a TON of lent! Can put a cover on it because it defeats the purpose of the “coolness” gets flat to fast.

I've been using this pillow for a little over a month, I like the coolness effect, just wish it stayed a little fluffier.

Smells like chemicals isn’t cold at all won’t use it. Bought one a few years ago and it was awesome. This one is nothing like the 1st one I bought.

Warms up in just a couple mins, its silky so it slides out of pillow cases or off the bed and it's too hard.

I read the reviews and they were great and I thought I'm going to give this pillow a try. I gave it two nights and realized these are not for me! It gave us both neck aches and headaches, they are too hard for us.

I have tried dozens of pillows over the years. Worst pillow ever. I don't recommend this one. The inner material is to firm. Your head is unable to sink so this leaves your neck in an awkward angle. I had a nasty pain in my neck every morning that took hours to recover from. I gave this pillow two weeks and it did not improve. My wife then tried this pillow as she did not believe me. She only used it for one night and her neck was so bad it took 3 days to recover from the pain.

This was purchased for my mother-in-law. Her neck was hurting, and she had difficulty sleeping. I purchased this same pillow for myself a few years ago. It helped me get some sleep and comfort from my aching neck. It seems to be working for her as well.

I love this pillow. It is the most comfortable pillow i have ever owned and it always stays cool. My wife is constantly trying to switch pillows with me. She wanted a different cooling pillow and so I bought it for her and now every chance she can get she tries to switch hers with mine.
