Question: Any bad effects?
Document: Great idea...poorly made product. Really bad. It was like sleeping on a leaky floatation device. Of course, you may need a floatation device when you wake up in water. :)
Love it. Keeps me nice and cool. Was weird to have a cold head at first. It is really awesome and definitely cold.Only complaint is that you have to make sure it doesn't get bunched up - do not sit/lay with it behind your back, otherwise the foam inside can fold over itself.. There are instructions on how to fix it and it works, but can take time if its bad. I've had mine for a year.
I bought this for my daughter, the good is it cools, the bad is that you have to add water, get out the air (I made a mess during this step), then during the first night the cheap memory foam insert wads up. I managed to get the foam unbunched and had to start the process over again to do it. Night two, same story, night three, night four same story.
This thing disappoints me. I love the cooling feel of it and you really can't beat that, but it does smell plasticy and I could sleep with that smell although I did ask my husband if he thought inhaling that scent was bad for me. Like another reviewer I do have down pillows and the blasted thing does not stay flat, it bunches up and it moves and if you place it on top of the pillow same thing.
I was worried about buying this because so many people wrote bad reviews for it. I have had no problem with it leaking. You are not supposed to freeze it. I never have but I think that's why some people had bad experiences with the chillow. It can only absorb so much heat and then it needs to be set aside to get cold again. I like it though. My girlfriend and I fight over who gets to use it on nights that are really hot outside!
We followed all the instructions and the Chillow was cool at first. However it got hotter and more uncomfortable through the  night, by the end of the night I was perspiring even more then I had before. The Chillow was like putting a peace of plastic over the pillow and turning up the heat to 100 deg.My experience was very negative and I returned the Chillow to the company. The company I purchased the Chillow from service was fine everything was as described and I would not say anything bad about the shipping .
Ughh the 1st two weeks of this pillow were amazing. I was so pleased I bought one for my mom, my sister & my niece!2nd day of my third week I woke up wet, which i was used to in life before chillow. I sweat so bad every night i always woke up slightly damp. Dang I thought, I must have moved over to my husbands side of the bed & used his pillow instead, i rotated a little & put my head back down.
this is Donna I  purchased this pillow. It is a piece f junk. I has a terrible chemical smell that does not leave the pillow no matter what you try. I even tried sleeping with a  dryer  sheet in the pillowcase on top of the chillow did not help.I.m telling everone do not buy. It's probobly hazardous to your health!
only used it one night but had a very satisfying night's sleep so that makes me a happy shopper. Thank you
it makes my life and sleep more manageable as a suffer of a painful disease and it is good to be able to sleep
