No matter the time of year, a cooling mattress pad is a must for those who like to sleep in the heat. As someone who regularly struggles with night sweats, I can tell you that the right mattress pad can save you from tossing and turning all night, throwing off the covers when you get hot, and waking up feeling refreshed.
If you woke up this morning with sweat oozing out of every pore, it’s definitely worth swapping out your moisture-wicking silk pillowcases and lightweight Egyptian cotton sheets. But if overheating at night is a real issue, investing in a breathable mattress will likely make the biggest difference to your sleep.
There are many soft mattress toppers on the market that are thoughtfully designed to balance comfort and cooling, improving air circulation, wicking away excess sweat, and even actively cooling your body if your body temperature rises. Plus, a good mattress topper can completely change the comfort level of a worn-out or too-firm mattress—improving every aspect of your sleep.
Are you ready to wake up feeling rested and refreshed, not hot and flushed? From simple models made with moisture-wicking materials to hybrid models with advanced cooling technology and ergonomic support, here are the best cooling mattress covers to know about in 2025.

The best cooling mattress topper is primarily designed to wick heat and moisture away from the body, is made from materials that are considered breathable, and has temperature-regulating properties built into its design. If you’re looking for a natural product, latex or wool covers are worth considering, but gel-infused memory foam or hybrid mattresses can also have a real cooling effect if their mattresses and covers are well-ventilated to allow air to circulate and dissipate heat. We also consider the thickness of the cover, as thicker covers are likely to retain more heat. Additionally, choosing a mattress topper with a removable cover that’s machine washable will ensure easy maintenance.
Cooling mattress pads are specifically designed to regulate your body temperature while you sleep, which can certainly help solve the common problem of overheating in bed. So it’s safe to say that they work.
Don’t expect to feel like you just stepped out of an ice bath, though. For most people, a cooling mattress is an effective solution on a normal day. However, if you’re in the middle of a heat wave or just feeling pretty hot, you may need a reliable fan to provide a little cooling air.
While traditional closed-cell memory foam mattress toppers are notorious for causing overheating and night sweats, most modern models today feature a breathable open-cell structure that allows for maximum air circulation. Additionally, many premium models are infused with cooling gels and refrigerants (like copper, graphite, and charcoal) to help further dissipate heat. So there’s no reason why you can’t enjoy the pressure-relieving benefits of a memory foam mattress topper while staying cool at the same time.
Do you often wake up feeling hot, stuffy or stuffy? A natural, breathable, temperature-regulating, hypoallergenic wool mattress pad has a pillow-like feel and is great for cooling the mattress for allergy sufferers. They are usually made from 100% British wool and are quite expensive.
If you’re looking for a more budget-friendly mattress, hollow fiber mattresses are also an ideal option. Hollow fiber is made from lightweight fibers that have a much lower density than traditional memory foam. This means that while it doesn’t provide the same level of cushioning as higher-end materials, it makes up for it with superior breathability.
When it comes to mattress covers, moisture-wicking fabric is key. Tencel and nylon are popular options, but if you don’t want to use synthetics, bamboo and silk are also good options. Cotton, on the other hand, tends to absorb moisture more easily, and so may cause problems for buyers who suffer from night sweats.
At GLAMOUR, all interior design guides are written and edited by our in-house team of freelance writers and testers, led by GLAMOUR Business Writer (myelf) Mayola Fernandez. Since joining the team in 2023, I’ve built up a wealth of knowledge in sleep content and have written extensively on the topic since 2021.
When it comes to mattress toppers, I’ve tested more products than I can count (it’s a tough job, but someone has to do it!). But because comfort is so subjective, I also tapped into the expertise of our team of sleep writers and editors, consulted with industry experts, visited showrooms, and conducted extensive research. To do that, we read hundreds of customer reviews to boil this review down to a simplified guide of the 11 best mattress topper options on the market, each of which has undergone rigorous testing and earned a GLAMOUR certification. Read on for more on our testing process.
Our dedicated in-house testing team put some of these cooling mattress covers to the test and tested them in our own homes to determine their effectiveness. We spent muggy nights and endured heat waves sleeping on these breathable mattress covers to evaluate their ability to regulate nighttime temperatures. For those who haven’t had a chance to test them out for themselves, we’ve combed through the reviews and asked experts for their top picks.

This luxurious 9cm thick mattress topper provides unparalleled comfort and pressure relief that will transform the feel of any mattress. The removable and washable top cover makes it easy to clean, while the graphite coating helps maintain the optimal temperature throughout the night.
You get a 100-day free trial period during which you can try out the mattress and return it, and if any product doesn’t live up to your expectations after the trial period, you can also take advantage of the additional 10 years of warranty.
It is noteworthy that there is no mention of an anti-slip layer or elastic bands to secure the mattress, but of course a protective cover or sheet can be used for this.
With award-winning technology used in their famous mattresses, this mattress is undoubtedly one of the most advanced options on the market today. So it’s no wonder it has won a ton of awards!
It features an impressive 2,500 Aerocoil springs for improved support and comfort, as well as a layer of open-cell Simbatex foam that provides 30 times more air circulation than traditional foams and is infused with natural graphite to wick away sweat. Plus, the breathable mesh top layer provides maximum heat dissipation. No more hot, humid nights!
This mattress pad has a non-slip base and four wrap-around corner straps that keep it securely in place, so you don’t have to worry about it slipping off your mattress, sofa bed, or air bed.

This affordable Aidapt mattress from Argos is made from memory foam infused with cooling gel and will improve your current mattress topper tenfold.

The mattress’s comfortable depth is 5cm, providing extra cushioning without significantly changing the feel of the mattress, making it ideal for those looking for extra comfort without changing the overall firmness of their mattress.
Rave reviews from customers attest to its benefits, with one sharing, “I was a little worried after reading that memory foam mattresses can make you sweat, but I decided to give it a try. Even in the middle of winter, I use a 2.5 tog summer blanket because I get too hot at night, but with this mattress I can happily say it has noticeably improved my body temperature while sleeping.”

We love the eco-friendly Panda London mattress pad. Not only is this mattress pad a top choice in terms of eco-friendliness, but it’s also highly recommended for people with eczema and sensitive skin. It will help extend the life of your mattress as it adds an extra layer of cushioning and protection that absorbs much of the wear and tear and reduces the pressure on the mattress underneath.
The mattress comes with a convenient removable cover in case of accidental spills, as well as adjustable straps that are ideal for securing on deeper mattresses. It is a top choice for side and back sleepers as it relieves pressure on the neck, shoulders and back at the same time.
This mattress is made of memory foam and is slightly softer than the other mattresses in this release. If you prefer a firmer sleeping surface, this mattress may be too soft for you.

The price of this Dorma mattress is comparable to the Saatva mattress in the US. The mattress is filled with high-quality support memory foam that molds to your body for maximum support, and the cover is made of ultra-cool TENCEL fabric that prevents heat retention and is 50% more moisture-wicking than cotton.
Over 2,000 customers are fans of this brand, but one of the drawbacks we found when comparing the two premium brands is the lack of an antimicrobial coating on Dorma. However, Saatva is a bit more expensive.
While neither Dorma nor Dunelm offer a trial period for this product, samples are available in store so you can have more confidence in your new sleeping surface before you buy. Additionally, for your peace of mind, this product comes with a 10-year grace period.
Using these Dunelm promo codes you can save money on our range of the best cooling mattress toppers for real comfort.
Sealy is a brand that is similarly priced to its popular competitor Silentnight, but this product is a real best seller. We bought it – it’s anti-allergenic, anti-bacterial, has a two-year warranty and promises to be odor-free.
This quilted mattress is soft and velvety, with skin-friendly microfiber fabric for long-lasting comfort. It’s designed to enhance your bed by providing an extra layer of soft support, and is available in sizes from twin to king-size. It also comes with elastic corner straps to keep it securely in place.
In our experience, polyester filling and upholstery in bedding (from duvets to sheets) isn’t as durable as latex, organic cotton and silk. However, at an affordable price of £28, we still think it’s good value for money. Plus, unlike most microfibre or hybrid mattress covers, the mattress cover can be packed away and thrown in the washing machine or tumble dryer at your convenience.

In case you were wondering, wool is actually a very breathable material. And it’s completely natural! Despite wool’s thermal properties, its natural thermoregulatory properties allow it to effectively keep you warm in the winter and cool in the summer by wicking away sweat.
The Woolroom luxury mattress pad is made from natural materials and is a great choice for allergy sufferers, with its organic cotton cover wicking away moisture and heat to keep you cool all night. It also features elastic bands that prevent slipping and ensure your mattress pad stays securely on your mattress at all times.
It is eco-friendly and comes in a variety of sizes, but it is worth noting that it is not home washable, so you will need to take it to the dry cleaners from time to time.
For those nights when a light summer blanket just isn’t enough, this cooling mattress pad will definitely help you stay as comfortable and cool as possible – no matter the weather. Perfect for warm evenings, it features intelligent “climate control technology” that helps your body regulate its temperature, preventing sudden overheating.
You won’t have to worry about night sweats either: the partial cotton cover effectively wicks moisture away from your skin, ensuring it stays dry for a good night’s sleep. But if you feel like your mattress needs a refresh after a particularly muggy night, simply throw the entire cover in the washing machine.
While reviewers agree that this mattress is very comfortable, some note that its cooling properties are not as noticeable as other mattresses.

White Company is a favorite brand of ours that offers cotton duvet covers, silk pillowcases, and more, all of which are truly luxurious. This quilted mattress cover is no exception. It has received positive reviews from customers, and with these reviews, you can find answers to any common questions that the brand may have missed.
While it is soft, it is more of a protective layer than a memory foam or fiber mattress, so it won’t provide the same support as the other mattresses in this guide. That being said, the cotton filling will certainly smooth out any spring or indentation imperfections that are found in cheaper mattresses.
As expected from The White Company, the quality is excellent. Made with Outlast® technology, originally developed by NASA, the cotton fabric absorbs excess heat and gradually releases it as your body temperature drops, ensuring a comfortable sleep in any weather.
