Regardless of the season, cooling mattress toppers are essential for hot sleepers. As someone who regularly battles night sweats, I can tell you that the right mattress topper can be the difference between tossing and turning all night and throwing the covers off when you overheat; and waking up feeling completely refreshed.
If you, yet again, woke up this morning with sweat seeping from seemingly every pore, swapping to sweat-wicking silk pillowcases and lightweight Egyptian cotton bedding is definitely worth doing — but if overheating at night is a real issue, investing in a breathable mattress topper will likely make the most noticeable impact on your slumber.
Cleverly designed with both comfort and coolness in mind, there are lots of plush toppers out there that have been expertly engineered to enhance airflow, wick away any excess sweat, and even actively cool your body as your temperature increases. Plus, a trusty topper can also completely transform the comfort level of a worn or overly firm mattress — so you'll be upgrading every single aspect of your sleeping set-up.
Ready to wake up looking and feeling refreshed, rather than roasting hot and red-faced? From simple models made with sweat-wicking materials, to hybrid ones that boast premium cooling technology and ergonomic support, these are the best cooling mattress toppers worth knowing about in 2025.

How to choose the best cooling mattress topper?
Primarily designed to draw heat and moisture away from the body, the best cooling mattress toppers are made with well-known breathable materials, and boast temperature-control properties within their construction. Latex or wool toppers are worth looking out for if you're after something natural, but gel-infused memory foam or hybrid mattresses and toppers can also be really cooling if they've got a well-ventilated design that promotes airflow and heat dissipation. We'd also consider the thickness of the topper too, as thicker options are likely to retain more heat. Plus, opting for a mattress topper with a removable and machine washable cover will ensure easy maintenance.
Do cooling mattress toppers work?
Cleverly designed to regulate your body temperature while you sleep, cooling mattress toppers definitely help with the common issue of overheating in bed. So it’s safe to say that they definitely work.
That being said, don’t expect to feel like you’ve just stepped out of an ice bath. Cooling toppers are effective of an effective solution for most people on a typical day. However, if we’re in the midst of a heatwave — or even if you’re just someone who runs rather hot — you might need a little extra cold air from a trusty electric fan.
What material is best for cooling toppers?
While traditional closed cell memory foam mattress toppers built up quite the reputation for causing overheating and night sweats, most modern day models now boast breathable open-cell structures to maximise airflow. Plus, many advanced models are also infused with cooling gels and agents — like copper, graphite, and charcoal — which help to further dissipate heat. So there's no reason why you can't reap the pressure-relieving benefits of a memory foam mattress topper, while still staying nice and cool.
Constantly wake up hot, stuffy, and sniffly? Naturally breathable, temperature-regulating, and hypoallergenic, wool mattress toppers have a cushion-like feel, and make great cooling mattress toppers for those who also suffer with allergies. Typically made from 100% traceable British Wool, they do often come with quite a hefty price tag.
Alternatively, hollowfibre toppers are ideal if you're after something a little more budget-friendly. Crafted with lightweight fibres, hollowfibre is far less dense than traditional memory foam — meaning that although it doesn't offer quite the same level of cushioning as the more premium materials, it somewhat makes up for it by being super breathable.
When it comes to the cover of your mattress topper, a sweat-wicking fabric is paramount. Tencel and Nylon are popular picks — but bamboo and silk are ideal if you're steering clear of synthetics. Cotton, on the other hand, is more likely to hold moisture — and can therefore cause issues for buyers suffering with night sweats.

- Materials: Memory foam, Hydro Foam™ and rayon from bamboo.

We love Panda London for its eco-friendly bed sheets. This mattress topper is not only a top pick for sustainability, but it's a super suggestion for eczema and sensitive skin sufferers. It will help to extend the life of an existing mattress by adding an extra layer of cushioning and protection, which absorbs much of the wear and tear and reduces strain on the underlying mattress.
There's a handy removable cover should any accidental drinks spillages occur, along with adjustable straps, which are ideal for securing it in place on deeper mattresses. It's a top pick for side and back sleepers as it relieves pressure from the neck, shoulders, and back at the same time.
With its memory foam design, this topper is a little bit softer than some others in this edit. If you prefer a firmer sleeping surface, it may make your mattress feel a bit too plush.

Dorma Tencel Blend Memory Foam Mattress Topper
Specifications -
- Best for: Contoured support of pressure points.
- Sizes available: Single, double, king, super king.
- Materials: Polyamide, Tencel, polyester, cotton and visco elastic polyurethane foam (not to be confused with Viscosoft, the US topper brand by a similar name).
- Machine washable/tumble dryer friendly? No, sponge spot clean.
This Dorma topper is comparable price-wise to the Saatva topper over in the US. Filled with a premium supportive memory foam that moulds to the shape of your body to ensure maximum support, it's finished off with a cover made with oh-so-cooling TENCEL — a material known to prevent heat retention, and that is capable of absorbing moisture 50% better than cotton.
More than 2k buyers are fans, but our one negative comparison between the two high-end brands would be the lack of antimicrobial coating on the Dorma. Then again, the Saatva is ever so slightly more expensive.
While neither Dorma nor Dunelm offer a trial period on this product, feeler samples are available in-store so you can get a more confident feel for your new sleep surface before committing. Plus, it's backed by a generous 10 year guarantee for peace of mind.

Sealy Anti Allergy Hollowfibre Mattress Topper
Specifications -
- Best for: The ultimate dryer friendly and machine-washable affordable topper.
- Sizes available: Single, double, king, super king.
- Materials: Polyester.
- Machine washable/tumble dryer friendly? Yes to both for the cover.
Sealy – a similarly priced brand to its ever-popular competitor Silentnight – have really hit the ball out of the park with this one. Anti-allergy for bacterial protection, a 2-year guarantee and the promise of odour resistance – we're sold.
Soft and squishy to the touch, this quilted topper boasts a skin-safe microfibre cover, and provides durable and long-lasting levels of comfort. Purposefully designed to enhance your bed with an extra layer of soft support, it's available in sizes from single to king. It’s also secured with elasticated corner straps to keep it firmly in place.
In our experience polyester makeup and fill bedding – from duvets to bed sheets – aren't as durable as, say, latex, organic cotton and silk. That said, at budget-friendly price of £28, we still think it's great value for money. Plus, unlike most microfibre or hybrid mattress toppers, the whole thing can be bundled up and thrown in the washer or dryer at your convenience.

ICYMI, wool is actually a really breathable material. And it's completely natural! Despite being insulating, wool's natural thermoregulation properties make it effective at keeping you warm in winter and cool in summer by wicking away sweat.
Woolroom's deluxe topper is an excellent choice for allergy sufferers thanks to its natural materials, and its organic cotton cover helps keep you cooler throughout the night by wicking moisture and heat away. Plus, it includes elasticated bands to make sure no sliding occurs, ensuring your topper securely grips your mattress at all times.

For the nights where a lightweight summer duvet is not cutting it, this cooling mattress topper will definitely help ensure you stay as comfy and cool as possible — whatever the weather. Ideal for warmer nights, it uses clever 'climate control technology' — which assists your body in regulating its temperature, so you don't experience sudden instances of overheating.
There's no need to worry about night sweats either; the partially cotton cover efficiently pulls moisture away from your skin, ensuring dryness to help you sleep. But if you do feel like your topper needs a refresh after a particularly toasty night, simply throw the whole thing in the washing machine.

The White Company is our go-to brand for cotton covers for duvets, silk pillowcases and so much more – everything is just so luxe. This quilted mattress protector is no exception. It's well reviewed by buyers and, thanks to said reviews, you'll be able to find answers to any FAQs the brand might have missed.
While it is padded, as a protector more than a memory foam or fibre topper it won't provide as much support as the other toppers you may read about in this guide. That said, the cotton fill will certainly take the edge off any pokey springs or dips in cheap mattresses.
As expected from The White Company, the quality is exceptional. Crafted with Outlast® technology — originally developed by NASA —the pure cotton fabric absorbs excess heat and releases it gradually as your body temperature drops, ensuring a comfortable night's sleep regardless of the weather.

You can bid farewell to nighttime discomfort caused by overheating, as this topper is expertly engineered to maintain a consistent temperature throughout the night, addressing a common concern associated with traditional memory foam.
Made with Simbatex® foam infused with graphite, it boasts superior airflow, circulating thirty times more air than conventional memory foam and the addition of up to 1,500 patented Aerocoil® springs ensures comprehensive body support.

A top pick for a mattress topper with adjustable firmness levels.
The cover is soft to touch, ensuring a smooth and comfortable feel when you lie on it and it's also fully removable for washing. Plus, with a 10-year warranty, you can rest easy knowing your purchase is built to last.
What’s the difference between mattress pads, toppers and protectors?
While toppers are typically dense, cushioning, and designed to enhance or alter the feel of your existing mattress, a mattress protector is essentially an extra-absorbent additional bed sheet that protects your mattress from any spills and stains. Typically thinner than a topper but more substantial than a protector, a mattress pad sits somewhere in-between the two.
What thickness of mattress topper should I get?
Although it'll largely be down to your own personal preferences around comfort and support, the condition of your actual mattress should also definitely comes into play when deciding on the thickness of your topper.
If you've got a relatively new mattress — and you're pretty happy with the level of comfort it provides — opt for a topper that's 3-5cm thick. Trying to breathe some life back into a much older model? Don't settle for less than 7cm.
Can I wash a mattress topper?
Hollowfibre and cotton toppers are typically fine to go in the washing machine — and they're also generally squishy enough to just about squeeze in the drum. In fact, most can also even be tumble dried on a low temperature.
Toppers made with memory foam, latex, or gel typically aren't safe to sling in the washing machine — but they do typically have removable covers that are safe to run on a delicate wash. Besides, you're unlikely to be able to fit a whole memory foam mattress topper in your machine, anyway.
