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.

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.

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

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.

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 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.

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 have tried several memory foam pillows and most were way too hard, and too high. They made my ears hurt and neck sore from sleeping on them. The previous reviews on this memory foam pillow stated that many people felt it was too soft and not particularly high--which was what I was looking for, as I have neck and shoulder muscle issues and often wake with a headache. This Serta Forever Cool memory foam pillow is a perfect balance of memory foam with some give so it feels great for back sleepers. Side sleepers will put their arm under it to boost it up. It has a cooling side and a regular side. If you like a pillow that is very high, or very firm, this is not for you. I think it is pretty close to perfect for me.
