Review Content Stays cool all night Awesome for women who struggle with those mid-life power surges! I would buy this product again I suffer from night sweats adn this stops them so I can sleep through the night comfortably. I would recommend this to everyone. It is also very comfortable to sleep on. Yes! Yes! Yes! Finally, I received the Polar Pillow six days ago and I have now had six of the best nights sleep that I have had in years!! It is heaven . it is cool and had a good night sleep. Love it! I am more than pleased with the polar pillow. The first night I used it it had a strange odor. By the second night the odor was no longer there. Pillow feels cool even without the insert. Comfortable cooling pillow The pillow stayed cool for most of the night and I was able to sleep more soundly. Love it! I debated buying this pillow but I am so glad I did. I have a terrible problem waking up at night feeling like Im in a sauna. I havent even used the insert yet and it still works great. I will probably put the insert in during the summer. So glad I bought this. Like it! I have mixed feelings about it. Its wonderful for about 5 hours, after that its room temp or warmer. Its way way way too heavy. That being said, I love the 5 hours of comfort it does give me and I will continue to use it and Im grateful as can be for the hours it makes me more comfortable. Stays Cool Most Of The Night Great cooling pillow for a good nights sleep. It is a little cold at first but really soothes and relaxes for a good nights sleep. It is really heavy so there is no pillow flipping in the night. Had a restful sleep even on a warm night. ITS COOL It help me sleep better. Its great! Not as cool as I had hoped I put the cool pack in freezer for a couple days prior to use, but it was not as cool as others I have used. I does stay cool longer than others. First Time in Months I Was Able to Sleep I have Multiple Sclerosis and heat has been rough on me this year. I was waking up several times a night overheated, never getting a good nights sleep which affected me the next day. I am feeling very well rested finally. It works!! keeps his head cool most of the night. First Time in Months I Was Able to Sleep I have MS and heat is bad for a person with MS. I wasnt able to sleep because I was hot all the time. This pillow has fixed my problems and I sleep great now.
