The Mattress Cooler chills about a gallon of water using evaporative cooling and circulates that water through a thin PVC mattress topper to remove that 98.6 degree body heat trapped between your mattress and your covers that usually keeps you hot. It's a simple solution for a simple problem...which is why we can offer it for a fraction of some of the other mattress cooling products on the market. No...it won't connect to your smart phone or track your biorhythm...but it will keep you cool all night long while using less than a penny of electricity a night. How it Works: Common sense would tell you that this device couldn't chill any lower than room temperature, but in this case, common sense is wrong. Thanks to the physics of evaporation, we can actually chill water about 7-12 degrees below room temperature by using a fan and a surface area increasing membrane to accelerate evaporation. It turns out, this is about perfect....our pads provide excellent cooling with water temperature of about 75F against your body temperature of about 98.6F, allowing you to set your homes AC at about 76 from 8PM to 8AM every evening (instead of 65) ## Images ![Mattress Cooler "Classic" Chilled Water Sleep Cooling System 1 Pillow Pad Box Set (Black) - Image 1](https://m.media-amazon.com/images/I/7160Y8NOUoL.jpg) ![Mattress Cooler "Classic" Chilled Water Sleep Cooling System 1 Pillow Pad Box Set (Black) - Image 2](https://m.media-amazon.com/images/I/61gQkCecQEL.jpg) ![Mattress Cooler "Classic" Chilled Water Sleep Cooling System 1 Pillow Pad Box Set (Black) - Image 3](https://m.media-amazon.com/images/I/715tu1mzw2L.jpg) ## Customer Reviews ### ⭐⭐⭐ Lot of maintenance *by S***R on Reviewed in the United States on August 22, 2019* What you don't find out until opening and reading the manual is that the water spills easily and must be kept above the level of the bed to work properly. If it were a closed pumping system - like those used to cool computer CPU systems - then there wouldn't be a spilling issue. Plus, you have to empty the water and let it dry out every 2 weeks to keep it from growing mold inside it. Again, a close pumping system would solve this problem too. ### ⭐⭐⭐⭐ Not for constant 12 month Every-night use. *by M***T on Reviewed in the United States on March 25, 2020* This pump works well keeping me cool but the mattress pad is a little Uncomfortable. Last week it quit pumping Water due to the water Pump going DEAD on me after 8 months of Constant Nightly use. I reordered a New one a few days ago. I use it though in the Winter months Also. ### ⭐⭐⭐⭐⭐ Works great. *by M***G on Reviewed in the United States on November 26, 2020* I have MS ( Multiple Sclerosis ). I have spent years and $$$. Buy so called cooling pillows. They all ways get hot after 1/2 hour or so. Got tired of changing pillows. Or soaked pillow cases every night. This Pillow cooling system works ( All Night Long ). I but the fan on the lowest setting. And but two pillow case's on it. Other wise it gets too cold. I bought last July and use it every night. I did have a problem the 3rd week with a leak. One of the two pads i got with it. Customer Service sent out two replacement pad right way. Have not have problem since. I use Distilled Water in mine it keeps the much cleaner. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/136534570-mattress-cooler-classic-chilled-water-sleep-cooling-system-1-pillow](https://www.desertcart.jp/products/136534570-mattress-cooler-classic-chilled-water-sleep-cooling-system-1-pillow) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-23*
