The best cooling mattress pads

Cooling mattress pads might be the sleep-inducing solution you're looking for if you're suffering a bad night's sleep because of the heatwave – and doubly so if you suffer from night sweats, too.  

What is a mattress cooling pad? Essentially it's a cooling mattress topper made with materials, such as latex or gel-infused foam, that absorb extra heat and regulate your body's temperature for a comfortable night's sleep. You simply slip it on top of your mattress and beneath your sheets... and drift off in comfort.

Here, we've found the best cooling mattress pads available. For the very best mattresses, don't miss our comprehensive buyer's guide.

What is the best cooling mattress pad?

The best cooling mattress pads aren’t just adept at one thing, and many of our picks, including our number one, the Dunelm Gel Fusion Memory Foam Mattress Topper, also improve the support or comfort (or both!) of your existing mattress. 

If you’re after the closest thing to sleeping on a cloud, look for the thickest pad (on our list, that’s the Visco Therapy Luxury Gel Memory Foam Topper) but if you don’t want the money you spent finding a comfortable, supportive mattress to go to waste, any of our picks should still be plush enough to give you that floating feeling while, most importantly, cooling you down. 

Haven't got time to read the entire list? We've listed our top three mattress cooling pads below, along with their cheapest prices. You're welcome.


The best mattress cooling pad: Dunelm Gel Fusion Memory Foam Mattress Topper

1. Dunelm Gel Fusion Memory Foam Mattress Topper

Best cooling mattress pad: with list-topping cooling capabilities, this topper is memory foam, but not as you know it

Best for: Aches and pains
Size: Single, Double, King, Super King
Thickness: 2.5cm
Reasons to buy
+ Gel-infused foam to stop overheating + Air holes improve breathability 

If you like the idea of swapping your current mattress for a memory foam mattress, but aren’t sure about the investment, the Dunelm Gel Fusion memory foam mattress topper could prove a more cost-effective, and cooler, alternative. 

What makes it cooling?

Unlike traditional memory foam toppers, which can feel a little sweaty, this cooling mattress pad combines the comfort of memory foam with integrated gel particles that absorb and subsequently disperse body heat; microscopic ventilation holes throughout the foam improve airflow and increase breathability, too, vital for avoiding sticky situations on hot nights.

Who will it suit?

For its combination of spine-comforting foam and clever cooling, this cooling mattress pad gets our top spot, and it will be a good buy for anyone who needs a little extra support, from back pain sufferers to side sleepers who need a slightly softer surface to sleep on. That said, at just 2.5cm deep, it won't transform a hard mattress – but it soften it somewhat and will be comfortable for back and front sleepers, which some deeper, softer mattress toppers aren't.

As for cost, it's the most expensive on our list – but it's a year-round option that will really boost your existing mattress' comfort levels.

Easy to care for?

It's always worth rotating a topper, and this one's no exception. The quilted polyester cover is machine washable and can be tumble dried on a low heat setting, too. Useful for allergy sufferers who really want to limit those dust mites.

Best cooling mattress pad for comfort: Visco

2. Visco Therapy Luxury Gel Memory Foam Topper

Best cooling mattress pad for added comfort: the thickest layer of memory foam – but it doesn’t double up on warmth

Best for: Comfort
Size: Small Single, Single, Small Double, Double, King, Super King
Thickness: 5cm
Reasons to buy
+ Heat-dispersing gel + Really thick memory foam layer 

This Visco Therapy Luxury Gel memory foam topper, at 5cm deep, is a great option for anyone who needs a quick fix mattress replacement that's cooling, too. 

How does it cool?

This topper is a layer of high density visco-elastic polymer gel which is heat and pressure sensitive. Like our first pick, it serves to disperse body heat away from over-warm sleepers.

What does it do well?

Where this topper differs from our first pick is that it's double the thickness and feels like natural latex, so if you’re after a really cushioned sleeping surface and relief from niggling pressure points, or want to enhance the comfort of a subpar mattress, consider this. In other words, it's a good pick for side sleepers or back pain sufferers who are waking up with a) night sweats and b) achy joints.

Like our first pick, too, this mattress topper is hypoallergenic, making it a good choice for allergy and asthma suffers.

Why is it in second place?

It's not quite as highly rated by reviewers as our top pick, but we think it's really good value for money.

Best cooling mattress pad: Silentnight Cooler Summer Mattress Topper


Best cooling mattress pad for breathability: a good-looking alternative to gel pads for warm nights

Best for: Breathability
Size: Single, Double, King
Thickness: 5cm
Reasons to buy
+ Lofty, cushioned topper + Hypoallergenic 

There’s a lot to be said for gel, as our last few picks prove, but if you’re not a fan of how this feels, you could consider something like this microfibre Silentnight Cooler Summer mattress topper instead. 

How does it cool? 

Similar to our first choice cooling mattress pad, this one eschews the blue for a less clinical look and feel, plumping instead for a soft, breathable cotton cover and a lofty 100 per cent hollow fibre filling. 

Who will it suit?  

Anyone who's not a fan of the sink-in feel of a memory foam mattress, or anyone who's happy with the comfort levels of their existing mattress, but just want a cooler night's sleep.

What's it good at?

This cooling mattress pad is hypoallergenic, which means it does not contain any materials that are likely to cause allergies. And, because it's machine washable at 40°C, you can keep it fresh – a real plus over memory foam toppers where only the covers are washable. 

This Cooler Summer collection also includes pillows, duvets and mattress protectors, a bonus for anyone who needs more than just a cooling mattress pad to stay comfortable at night.

2You Magic Cooling Gel Blue Cool Pad Mat Orthopedic Mattress

4. Magic Cooling Gel Blue Cool Pad Mat Orthopedic Mattress

Best cooling mattress pad for hot flashes: our best cooler for short term use, keep it for yourself, or even let the dog have a go!

Best for: All seasons
Size: Double
Thickness: 2cm
Reasons to buy
+ Great range of uses + Immediate relief 

If you suffer from hot flashes or wake up in the night too hot to go back to sleep, this Magic Cooling Gel Blue Cool Pad mat orthopedic mattress makes for a quick fix. Believe it or not, people buy smaller ones as yoga mats and for pets who suffer in hot weather, too.

What makes it cooling?

With no water or refrigeration required, this medical grade cotton pad is filled with a harmless gel that delivers a cooling effect when in contact with your body. Reviewers say the cooling sensation is immediate and soothing.

Who will it suit?

It's good, not just for hot flashes, but for when you're suffering from sunburn, headaches or if the heat is stopping you from dropping off to sleep in the first place. Got a fever? Itchy eczema? This cooling mattress pad can offer relief for those, too. 

What doesn't it do well?

A common refrain is that this cooling mattress pad works well for short periods (an hour or two), but after it reaches your body's heat, it needs replacing – or time to cool down. It works better when you move position regularly for this reason.

It's worth noting, too, that this type of cooling mattress pad doesn't cover a full double mattress, but rather the central (body) section of the bed.

How to buy the best cooling mattress pad

Cooling materials

Cooling mattress pads are made from materials that absorb body heat and body moisture, and regulate your temperature. There are a range of different materials used (some well guarded secrets), but all aim to increase breathability, which helps cool you down.

Extra support

It's worth ensuring the cooling mattress pad you choose is comfortable for you specifically, too. Most combine cooling properties with extra support; those with a memory foam feel will suit side sleepers who prefer a soft/medium mattress, but perhaps currently sleep on a medium/firm mattress. 


Most cooling mattress pads simply sit on top of your existing mattress. If you're a fidget, look out for one that has elasticated straps to keep it in place; otherwise, you'll notice that you have to haul it back into position every few days.

What to match your cooling pad with

If getting over hot at night really is a problem for you, you might need to think of other solutions. For the odd hot night, a fan is a good solution – see our selection of the best fans for bedrooms and beyond to find a quality buy at a good price. Buying a mattress that's breathable is a must, if yours is more of a long-term problem.
