It is a water-cooled mattress pad. Not only can it cool you and maintain the temperature, but it can warm you as well, making it an all-season mattress pad. The remote-controlled temperature can go as cool as 55 degrees Fahrenheit or as warm as 110. How does it work? The poly/cotton pad has tubes running through it. The tubes attach to the machine holding the water, which circulates continuously through the pad. The machine is quiet, running at under 45 decibels, which is equivalent to a computer fan. If you share a mattress, there is a split option to allow the temperature on each side of the bed to be controlled separately. Available in sizes: single, twin XL, full, half Cal king, queen, king, California king. Chili Technology offers a 2-year warranty as well as a 90-day money-back guarantee. 8. Mattress Cooler Classic The Mattress Cooler Classic is a water-cooled mattress pad. The fan, circulation pump, and remote were upgraded after two years of feedback from customers. It’s now quieter and boasts a 66% larger water tank. The water circulates through the pad, absorbing excess heat from your body. This is a simpler unit than the chiliPAD™ without any split-control options, but it’s much more affordable since it doesn’t have the bells and whistles. Available in sizes small and large. Mattress Cooler doesn’t offer a warranty, but they do have a 30-day money-back guarantee, minus a $20 restocking fee, if you’re not happy with your purchase. Why Is Cooling Important for Sleep? Thermoregulation, or how your body heats and cools itself, is tightly linked to the circadian clock. This circadian rhythm is responsible for your body losing heat in the evening hours just before sleep. This heat loss is what tells your body it’s time to wind down and head to bed. The circadian rhythm is also the reason your body starts warming up again around 4 a.m. as your body prepares to wake. Your sleep can be disrupted by temperatures below 54 degrees Fahrenheit and above 75 degrees. The sweet spot for many falls between 60 and 67 degrees. The right sleeping temperature for you to have a cool night’s sleep may be affected by: Season Bedding Pajamas Body temperature Gender Stage of life (think hot flashes) Daytime activity level Your sleep can be disrupted by temperatures below 54 degrees Fahrenheit and above 75 degrees. Determine Why You’re Sleeping Hot Why are you sleeping hot and what factors are contributing? One thing to take an honest look at before shopping is why you are sweating in your sleep. Have you always been a hot sleeper? Are you troubled by night sweats caused by hot flashes? Are you sweating because your sleeping environment is too warm? These reasons will influence your choices as you shop for a cooling mattress topper. As you are well aware, feeling too hot can get between you and a good night’s sleep. If night sweats or hot flashes are a problem for you, you’ll be glad to know there are a variety of cooling mattress toppers which could give you a substantial quality-of-life upgrade. If you don’t own a cool mattress, a cooling mattress pad or topper can turn bad nights into good nights full of restful sleep. But how do you know which one you need? What’s the Difference Between a Mattress Pad and a Topper? Many sites use these two terms interchangeably. While they are similar, they have some fairly significant differences in terms of function and comfort. Mattress Pad A mattress pad is an additional layer of comfort to attach to your existing mattress, usually with a fitted skirt. The skirt is similar to a fitted sheet. It has elastic at the edges and pulls down over your mattress, tucking under the edges to keep the mattress pad from slipping off. Mattress pads are thinner than mattress toppers. They are generally quilted to keep the fiber filling in place, which also provides some cushioning and a sumptuous feel. The main fillers are: Cluster fiber — looks and feels like down Down filling — has longevity Feather filling — insulating despite the lighter weight Cooling mattress pads are designed to be breathable. Some also function as a mattress protector, safeguarding against moisture and spills while sealing out bed bugs, dust mites, and allergens for a hypoallergenic option. The beauty of a mattress pad is most of them can be whipped off and thrown into the washing machine for easy care. Mattress Topper A mattress topper is thicker and made of memory foam or latex. Toppers sit on top of the mattress and can be 2 to 4 inches thick. A few are 5 or 6 inches thick, approaching the size of a mattress. Rather than having a filling, a gel-infused memory foam topper is a solid layer of foam to add cushioning for pressure point relief. New manufacturing methods use viscoelastic foam, which has an open cell structure to allow air to circulate. They are a little firmer to minimize sinkage and thus reduce heat trap. Latex mattress toppers have an open cell structure and sleep much cooler than regular memory foam toppers. Some models of mattress toppers have a skirted cover, like a fitted sheet, by which it is securely attached to your mattress. The covers can usually be machine-washed, but the foam itself can only be spot-cleaned. Toppers with a fitted cover are far superior to those that just sit on top of your mattress. How Do You Know Which You Need? All cooling mattress toppers and pads will offer some degree of cooling. The clincher is going to lie in how much cooling and what other features you need. Back pain and pressure point issues demand a topper made of latex or gel-infused memory foam. Your choice of these two materials will be influenced by your budget. If you just need a cooler surface to sleep on, coupled with mattress protection to extend the life of your mattress, then you’ll be fine with a cooling mattress pad. You can go either way in the case of allergies, depending on whether you also need more support for pressure points and back pain. You’ll find more hypoallergenic options in mattress pads, however. If you suffer from hot flashes and night sweats, you’ll find the most relief from newer temperature-sensitive materials like Outlast™ technology which is able to monitor your skin temperature for changes and respond with cooling or warming. What Makes for a Cooling Topper? You might love the soft comfort of memory foam, yet dread the heat trap associated with those kinds of mattress toppers. Much of the heat trap is caused by the deep sink into pudding-like memory foam. It doesn’t have to be this way! Evolving manufacturing processes have brought many more options to the fore. Memory foam used to be associated with hot sleeping, but today’s processing methods offer an open cell structure which allows more breathability than ever before. The cooling function in mattress pads is a combination of their filler materials and the cover. Covers can be made of 100% cotton, wool, or silky rayon from bamboo. These fabrics work to keep the surface cool while the filler traps and releases heat. Notable Features of Some Cooling Mattress Toppers There are many more options now than there were 20 years ago. The following technological advances make a real difference in your sleep comfort and quality. Outlast® Technology If you have a fluctuating body temperature from hot flashes or other sporadic night sweats, you will appreciate Outlast® technology. It was first developed for NASA and uses phase change materials. This unique material is able to absorb, store, and release heat to optimize your thermal comfort. This cooling technology continually regulates the microclimate of your skin. As your skin heats up, the material absorbs excess heat and stores it. As your skin cools, the material disperses heat to warm you. This isn’t your typical wicking technology, absorbing moisture so it can evaporate. Outlast® technology manages your body heat to control the production of sweat before it can even begin. Outlast® technology isn’t used in only one type of mattress pad either. Some will go over your mattress like a fitted sheet while others will lay on top like an added pillow top. You can get these with a variety of fabric covers to suit your preference. Gel Memory Foam This type of topper is made of regular memory foam infused with cooling gel. Gel memory foam (also known as viscoelastic foam) may be a perfect fit for you if you experience back pain or pressure point pain. With so many options available, there isn’t any need to compromise comfort to switch to a topper with a cooling effect. Memory foam is notably silent and reduces motion transfer very well. These can be a huge boon for you if you share a mattress. Even if you have the mattress to yourself, low motion transfer allows you to move freely. Latex Used in some of the best mattresses, latex is made from the sap of the rubber tree and is a natural material. It springs back more quickly than memory foam which increases your freedom of movement. It’s as silent as memory foam with all the motion isolation you’ve come to expect from foam. It has an open-cell structure that allows air to pass through, keeping you cooler without the heat trap you may associate with traditional memory foam mattresses. Cluster Fiber You can get a 100% cotton or bamboo mattress pad with Revoloft™ cluster fiber which increases breathability even more. Cluster fiber is a down-alternative also known as ball fiber. This interesting fiber forms into little balls that can move freely within the cover, keeping any given area from mashing down or matting. Enjoy a Cooler Sleep We’ve shown you some of the best cooling mattress pads and toppers to help prevent you from overheating while you sleep. You’ve seen a variety of high-quality choices in a range of prices, so you’re more prepared to make a decision for your individual needs. All of these models can offer you some degree of cooling, so it’s a matter of budget and any other needs you may have such as hypoallergenic materials or pressure point reduction. Whether you choose a mattress pad, mattress protector, gel foam topper, or water-cooled pad, you’ll be sleeping cooler in no time.
