Therapeutic Cooling Pillow

Pillow Flipping is Passé

Chances are you've had a night (or two or 200) when you tossed and turned... and flipped your pillow umpteen times because you like a nice cool pillow to sleep on and yours kept getting warm.

Now there’s a better way to stay comfortably cool. The PolarPillow is an innovation in sleep technology, because it's half pillow, half
endothermic gel. The gel stays cool via a reaction between it and the ambient air temperature. While the pillow itself is much heavier than a regular pillow, you don't need to turn it to the "cool side" (you can rest on the comfortable gel, which stays cool for several hours at a time), so the weight is a non-issue. If you add the turbo-cooling pack, the gel will remain cool even longer!

Nick Segal, Duke University graduate and PolarPillow inventor, says that after a lifetime of pillow-flipping, he decided to engineer his own solution with help from his entrepreneurial partner and designer, Molly Lehnhardt. Made in Tennessee, these therapeutic pillows are sure to be a summer comfort for everyone, but they're particularly soothing for neck pain and migraine sufferers, athletes, pregnant women, and menopausal women (it won't cure hot flashes, but it'll make them easier to bear).

You'll spend 30% of your life on a pillow -- make sure it’s a cool one!

    Hi Daily Grommet fans! My name is Molly and I’m here with our founder, Nick Segal, representing PolarPillow. Are you a pillow flipper? Always looking for that cool side of the pillow? We are here to answer your questions!

    The pillow sounds great! I have neck pain due to rheumatoid arthritis. I need a pillow that will keep my neck in line with my spine. Can I mold the polar pillow to the right shape for me?

    @Montclairianne: The gel is pretty malleable, but if you suffer from arthritis, we would recommend getting a pillow specifically designed for this condition.

    Can someone explain 'endothermic'...sounds high-tech.


  • Molly

    @Victor K: In this case, the word "endothermic" describes the process in which the gel absorbs the temperature from its surroundings. When you're on the pillow, it absorbs the heat from your head, creating the cooling sensation.

    @Molly Lehnhardt: You mean how heat flows through any substance,even water/ammonium nitrate combo. [Heat always flows from hot to cold.]

    Does your "proprietary secret sauce" contain ammonium nitrate?

    Thanks for the info.

    Oh, what is the heat capacity of your pillow until it reaches 98.6 since it is drawing the heat from the head? How long will this take?

  • Molly
    Molly – Special Guest
    6/30/2011 4:22 PM

    @Victor K: There is no ammonium nitrate in the gel. In standard room temperature condition, it takes approximately two hours for the gel to reach heat capacity. Our goal in designing the PolarPillow was to provide coolness for a long enough time for people to fall asleep.

    What is the endothermic gel? This seems like a product we would like, but would like to know what it is first. I have a few sensitivities.... I'm sure the pillows are non refundable, as on their website, so I want to know before I buy. If it is "proprietary secret"...can you just email it to me and not publish it? I'm just a mom in my 40's and my husband is a pillow flipper and pillow beater.

    Thanks so much!

  • Molly

    @Wendy: No, there is no latex. All the materials in the PolarPillow have undergone extensive quality control testing and are safe for use.

  • Rebecca
    6/30/2011 2:48 PM

    What are the care instructions? Can you wash this pillow? does it still work with a pillow case? what happens if the gel leaks out, is it toxic? wondering if it will harm my pets if this happens.



  • Molly

    Care Instructions:

    The PolarPillow should be hand-washed or spot cleaned only. We do not recommend putting the pillow in the washing machine. You may use a standard pillowcase on the PolarPillow and wash the pillowcase.

    The gel is sealed tightly inside the pillow. All the materials in the PolarPillow have undergone extensive quality control testing and are safe for use. Our testing confirmed that ingestion is not harmful, but we don't recommend it :-)

    I am liking the idea that you can skip turning on the AC with this pillow as a help. At least for the borderline temperature nights. We don't have AC in my house so I like it even more for that reason--beats Ziploc bags of ice. (Not kidding...)

  • Molly
    Molly – Special Guest
    6/30/2011 4:17 PM

    @Jules Pieri: Ziploc bags of ice... very resourceful! We hope we can help, although the PolarPillow performs best in standard room temperature conditions (i.e. up to 75 degrees or so).

  • Cheryl
    6/30/2011 4:22 PM

    The info you provide says it "keeps it cool and comfortable for hours at the time"

    How many hours? If I sleep 8 hours am I still going to be a pillow flipper?


  • Katherine
    Katherine – Grommet Team
    6/30/2011 4:45 PM

    @Cheryl : It takes approximately two hours for the gel to no longer be effective. Their goal in designing the PolarPillow was to provide coolness for a long enough time for people to fall asleep.

    Do you ever have sales or discounts on the polar pillow? I am a constant pillow flipper and have been searching for cold pillows my whole life...when I was little I used to sleep horizontally across the top of my moms bed above her head, which she still jokes about how I was like a cat, but I remember clearly the soothing feeling of sleeping on top of or behind the cool pillows and without blankets ( which she would try to cover me with anyway when I fell asleep. ) now I have buckwheat husk pillows which are cooler than regular pillowd but not as much as I'd like still. I'm a student tho so it's abit pricey for me, so I'd love to know about any sales or specials or discounts. Also, in 2 hra when it warms up do u flip it? What are u supposed to do at this point? Thanks!!

    @Melanie: I love the image of you sleeping like a cat above your mom's bed. It would be great if this pillow could provide you the good night's sleep that you are looking for. The Polar Pillow will be cooler than buckwheat husk pillows. It is surprising when you first feel it! It's designed to stay cool for plenty of time for you to fall asleep. I don't know if this product will be available in the future at a discounted price. You should put it on a wish-list. Others are often happy to get you something when they know it's exactly what you want.

  • Jennifer
    7/17/2011 5:17 PM

    I'm wondering if the pillow is only cool for 2 hours, does the heat evenly disperse through the pillow? For instance, if I tend to sleep toward one side of the pillow, will the other side stay cool? If so, could I just move over and enjoy more cooling? I'm very interested because I have a problem with turning my mind "off" at night and some of the research suggests that cooling the frontal lobe will help with this. Wonderful product concept! I'm looking forward to possibly purchasing!

  • Katherine
    Katherine – Grommet Team
    7/17/2011 11:17 PM

    @Jennifer: Great question. I have forwarded it to Molly and Nick and will let you know what they say. It would be great if this could help you get some rest.

  • Molly
    Molly – Special Guest
    7/18/2011 4:48 PM

    @Jennifer: If you sleep on one side of the pillow the other side is often still cool -- it depends on how much heat your head gives off!

    You're correct, a recent article in TIME says that cooling your head can help you fall asleep:

    Your circadian clock keeps your body at its warmest during the day for high-level functioning and its coolest during the night for dozing off. Researchers from the University of Pittsburgh School of Medicine reported that a primary cause of insomnia is hyperactivity in the brain's frontal lobes at night. This activity increases the brain's temperature making it difficult to fall asleep. Cooling your head at night can help slow down this activity and allow your brain to rest. Falling asleep may simply be a matter of cooling off. Read the full article in TIME

    I have bought two of these pillows, one for me, a menopausal woman and life-long pillow-flipper; and one for my mother, who wakes up every morning with a migraine headache. I am hoping that we will both be happy with them. Will you consider a wholesale account so I may sell them in my yoga studio? Thanks.

  • Vilma
    7/21/2011 4:15 PM

    I saw a YouTube review of this pillow and the lady claims that the gel in the pillow seems to bunch up at one end of the pillow (down towards her head) thus making the top part of the pillow stick up and sort of over her head! Have you had anyone else comment on this problem? I'm thinking of purchasing the pillow, but I need to know if it does, indeed, have this issue where the gel all ends up on only one side of the pillow....I think that would be extremely uncomfortable.

  • Katherine
    Katherine – Grommet Team
    7/21/2011 5:14 PM

    @Vilma: No, none of our testers had that problem. There is some shifting of the gel, but overall it stays evenly distributed throughout the night.

  • Marianne
    7/28/2011 12:35 PM

    This probably sounds like a stupid question, but here goes...this pillow is supposed to "stay cool" for 2 hours, which is definitely long enough for someone to fall asleep, however, once the cold is gone, how does it get "cold/cool" again?? and how long does it take? Does it just get cool again once you're not laying on it? If so, how long does that take for the pillow to once again be cool?

    I would also like to know how "firm" the pillow is. I don't like soft pillows at all, I am currently sleeping on a Tempur-Pedic pillow, which is quite firm. Please let me know how the Polar pillow compares in firmness to my "memory foam" pillow.


  • Molly
    Molly – Special Guest
    7/28/2011 1:47 PM

    @Marianne: After you finish using the pillow and it is re-exposed to the air, PolarPillow only takes about 15-20 minutes to revive itself for the next use. Then you have two more hours of coolness. It should always be exposed to the air when not in use. For example, when you make the bed don't cover the PolarPillow with other pillows or blankets so it can capture the coolness of the room. FIRMNESS: The PolarPillow feels a little bit like sleeping on a water bed. I would say it's more firm than soft. It's definitely more firm than a feather pillow, but maybe not as firm as your tempur-pedic pillow - however the gel gives it a unique feel of it's own.

  • Sandra
    8/8/2011 9:05 PM

    1. What size is the pillow?

    2. Do you use a regular pillow case with it?

    3. If not, how do you keep it clean?

  • Katherine
    Katherine – Grommet Team
    8/8/2011 11:23 PM

    @Sandra: It is 20"x23". Yes, you should use a pillowcase with it to keep it clean. A standard size pillow case will work fine.

    Currently I'm using a medical grade gel cold pack which I put in the freezer--and it keeps me cool until about 2 am. By that time, it's absorbed all my heat and is very warm. So I do like the idea of having something that doesn't have to be put in the freezer or adding water like the Chill Pillow. I would rather have just your gel pillow without the pillow underneath. Have you considered offering it that way? Are there any stores that sell this that I could see the pillow before I buy? So glad you're working on this problem.

  • Molly

    8/25/2011 10:54 AM

    @Eileen Buckholtz: We don't offer the gel side without the filling underneath, but the pillow is malleable and can be flattened out if that's what you like. Our pillow is sold exclusively online right now -- so no retail offerings yet. Our founder used to sleep with ice packs too -- which is why he created the PolarPillow! Thanks for your questions!

    Hello. I am very interested in this pillow, but I am concerned about its safety. I have been chemically thrust into an early menopause by chemotherapy and suffer hot flashes and night sweats. My sleep is constantly disturbed by this. There are many "cool" pillows on the market and I have tried one memory foam option which off-gassed like crazy. It was so obviously toxic that I couldn't even be in the same room with the pillow, let alone sleep on it. After going through cancer treatment twice in six years, I am very concerned that a new pillow be safe. The wording about the safety of your pillow is very vague. I understand that you do not want to share the technology behind your pillow, but it is important for consumers to know exactly what they are exposing their bodies to. Is it at al possible to go into greater detail about this product's safety? Is there an odor? Does it off gas? Thank you!

  • Molly
    Molly – Special Guest
    5/4/2012 10:27 AM

    @ Miriam PolarPillow is odorless and does not off-gas. We have done extensive safety testing on all materials and there is nothing toxic in our product. The outer fabric is a basic woven nylon. The micro-air beads are tiny pieces of styrofoam and the gel is a non-toxic polymer blend.

  •  Mary
    6/6/2012 4:45 PM

    I have this and it does stay cool, not cold, but cooler than a regular pillow. My oversight was not paying closer attention to the details. Please note: this pillow weighs 15 POUNDS! Hard to lift with one hand when making the bed and it balls up on itself during the night. I really wanted to love this for $99.

    7/8/2012 7:24 AM

    I use a relatively small seed husk pillow for lack of something better. But it gets 'flipped' a lot and becomes uncomfortable (warm) or bunched up. After reading through the many questions and answers about your pillow I have a suggestion. Your dimensions are too large for me. If you made a pillow half as large and reduced your price accordingly I would very probably but two of them so I could switch between them as needed to get through the night on an always cooling pillow. Something for you to consider.

    I have the polar pillow and I do like it; however, many people that I have told about it question whether there is any risk that something/anything harmful is being emanated from the pillow into your head/brain. I notice that you say you have a "special sauce" but I would like to know specifically what the ingredients in the pillow are and concrete assurances (with back up facts) that none of those ingredients poses a risk --- i.e., how sure are you that having your head on this pillow every night for 8 hours a night over a period of years poses no health risk? Before recommending the polar pillow to others, I would like to know this. Thanks!

We understand your concern & also hope you can understand why the Polar Pillow Team has to protect the "secret sauce" behind their proprietary gel technology. Molly has assured us in earlier posts that "PolarPillow is odorless and does not off-gas. We have done extensive safety testing on all materials and there is nothing toxic in our product.

    @ amy The PolarPillow's cooling power comes from a polymer gel blend that has been used in other consumer products, such as ice packs, for many years. The pillows are produced by a top-tier American manufacturing company called Sealtech, which has been in business for over 30 years. Sealtech has a quality control department which provides thorough safety testing on all materials used in the products they make.
