If you’re a hot sleeper, investing in the best cooling mattress for your budget is wise. Clinical research has shown that lower body temperatures at night lead to better sleep, while higher body temperatures can lead to more disturbed sleep, so a cool bed will naturally make a big difference. As many of these breathable mattresses are made by the best mattress online brands in the world, they’re comfy and supportive too.
When your circadian rhythm (body clock) is on track, your body’s core temperature drops in the evening ready for sleep, then rises in the morning to help you wake. Some of you may feel as though you naturally ‘run hot’, while others may have a health condition that causes hot flashes (flushes) or night sweats. In these scenarios, overheating during sleep is incredibly frustrating as it leads to frequent waking.
Other factors like age, sleep style, and any weight or hormonal changes (ie, the menopause) can leave you feeling hot and bothered at night. Your hypothalamus (the part of your brain that produces hormones to regulate internal body temperature) can also be thrown off kilter by stress and anxiety. Living in a warm climate might also send you searching for the best cooling mattress.
But how exactly do they work? In a nutshell, these breathable mattresses use a range of materials and technology to absorb excess body heat, drawing it away so that you stay cool as you snooze. Take a look at our best pillow guide and you’ll see that these materials aren’t just for mattresses either.
If you’re wondering how the best cooling mattress could mean the difference between a replenishing night’s sleep and one where you’re tossing and turning due to heat, then read on.
1. The Purple Mattress: Best cooling mattress overall
Hot flashes (also known as flushes) are most commonly caused by hormonal changes such as peri-menopause, menopause and pregnancy. They come on suddenly and can be very disruptive to your sleep. If you're dealing with these or general overheating in bed, The Purple Mattress is worth considering.
Purple has built its brand on being temperature neutral, which means this mattress never gets too hot (or too cold). Purple also prides itself on offering the world’s first 'no pressure' surface, aka, its scientifically-engineered Purple Grid technology.
Purple Grid tech is good news for hot sleepers because it utilizes over 2,800 open-air channels to neutralize body heat. That's why we think it's the best cooling mattress for people experiencing hot flashes and even night sweats.
Even better, you can often find this mattress on sale among the best Purple mattress deals, and the brand also offers a hybrid version that's more suited to heavier sleepers. Why? Because it has a thicker layer of hyper-elastic polymer, plus coils, both of which adds up to increased airflow and a firmer feeling mattress so that heavy sleepers won't sink into the mattress. When you sink, heat gets trapped.
2. Saatva Classic: Best for hot sleepers with back pain
If you're a hot sleeper and you're dealing with back pain or aches and tension, you deserve the best cooling mattress made from luxury materials, putting comfort and support at the forefront. Step forward the Saatva Classic.
This beautiful mattress is made of three individual layers, including two layers of coils that guide heat away from your body and produce excellent airflow, keeping you cool all night long. The first layer of coils also helps to create a good sense of motion isolation. If you’re sleeping with a wriggly partner, this will stop them from waking you up with their tossing and turning.
The Saavta comes in three levels of firmness: plush soft, luxury firm, and firm. For hot sleepers, the luxury firm or firm options are best as, because they are deeper, there's increased airflow.
On top of the cooling performance, there's an added bonus of exceptional edge support. That's thanks to the Euro-style cushioned pillow top, which makes getting in and out of bed a lot easier. Check out our round-up of the best Saatva mattress discounts to get this mattress for less.
3. Tuft & Needle Original: Best cooling mattress for less
Tuft & Needle has based its entire business around offering the best cooling mattresses at far more affordable prices. Although the Tuft & Needle Original Mattress is made up of proprietary foam, this isn't your traditional memory foam mattress, so don't run away thinking it will be too hot for you.
Indeed, the Tuft & Needle Original Mattress uses specially adaptive foam to pull heat away from your body. It does this via a combination of cooling graphite and gel beads infused into the open-cell foam. Clever stuff, huh?
Open-cell foam is what makes this mattress so breathable. Add to that the graphite beads that absorb heat, plus ceramic gel to wick away heat and moisture, and this also quickly becomes the ideal cooling mattress if you're suffering from night sweats.

4. Eight Sleep The Pod: Best cooling mattress for couples
The Pod by Eight Sleep is unlike any other cooling mattress on the market because it’s controlled via an app. This high-tech mattress comes with a cooling cover that enables you to select your preferred temperature setting for each side of the bed. It's beyond perfect if you’re experiencing hot flashes, or you generally sleep hot, while your partner is convinced that there’s an Arctic blast blowing through the bedroom.
The Pod mattress is made up of CertiPUR-US certified foam and is medium firmness, so you’ll avoid sinking in to the mattress too much - that in itself causes overheating.
The adjustable temperature controls work via a small water hub that will sit next to your bed. A small network of undetectable tubes runs through the lightweight mat built into the mattress cover, and these will heat up or cool down to your preferred sleep temperature.
The Pod also comes with small sensors that enable you to track your heart rate, breathing patterns, and how much time you spend awake or asleep. Crucially, it'll also help you figure out which in-bed temperature helps you sleep the best.
This is hands-down the most expensive mattress on our guide to the best cooling mattresses, with a starting price of $2,795, rising to $3,495 for the Cal King, but it’s also the most advanced model. And thanks to its adjustable temperature, it's guaranteed to keep you cool at night.
5. Helix: Best cooling mattress for hot sleepers
There's a reason why the Helix Mattress features in multiple mattress guides, and that's because it's completely customizable, so you’re sure to get a good night's sleep with your chosen style.
For all of the hot sleepers out there, Helix is on a mission to keep you cool at night by using materials that don't trap heat within the mattress, and instead encourage air flow throughout the entire mattress.
Each Helix mattress comes with a removable, ultra-cool cover too. This absorbs your body temperature and transfers excess heat to colder parts of your body, creating a more temperature neutral sleep.
When you decide to purchase a Helix Mattress, you'll need complete a questionnaire that gives you the option to let them know that you are a hot sleeper. This will then be heavily factored in when it comes to building your perfect Helix Mattress.
6. Lalya: Best cooling mattress for night sweats
The Layla Memory Foam mattress is infused with copper particles to prevent overheating during sleep. The copper-infused foam is also antimicrobial, so when you lay on it, the copper compresses and forms a barrier that fights odor-causing bacteria and keeps your mattress fresh. If you're prone to night sweats, this could give you extra peace of mind regarding hygiene.
The other interesting thing about the Layla Memory Foam mattress is that it comes with flippable firmness. That means, one side is soft and the other is firm, so you can decide which you prefer based on your own personal preferences.
Both sides mean its great for all sleeping positions and it also has variable support areas to relieve any pressure on joints you may be experiencing. After all, if you're dealing with heat disturbances during sleep, you don't want any pain or tension waking you up too.

Why buy one of the best cooling mattresses?
If your sleep is frequently disrupted by you feeling too hot or experiencing hot flashes or night sweats, a cooling mattress could help take the edge off so that you can sleep cooler and better. Likewise, if it isn't you but your partner feels like they’re a mini radiator and sleeps very close to you, the best cooling mattress could help you both out.
Menopause, pregnancy and other hormone fluctuations cause hot flashes, night sweats and an elevated core body temperature, so a cooling mattress could play a part in lessening those symptoms.
Heavy sleepers who weigh over 200lbs may also find that they benefit from a mattress with cooling materials. Why? Without the right mattress for their body weight, heavier sleepers can easily sink into a mattress. When that happens, their body heat gets trapped in the mattress, leading to overheating.
Ultimately, only you will know if you need a mattress specifically designed to keep you cool as you snooze, or whether a more standard mattress will suffice. Waking up due to heat is never fun, and if it happens to you regularly, it could result in health conditions associated with consistently poor, broken sleep.
If you don't have the budget right now to buy one of the best cooling mattresses, read on for some further tips about how to stay cool when you sleep, and whether a cooling mattress pad could work for now.
Cool mattress pads
Do you just need a cooling mattress pad?
If you’re looking to cool down your sleep but aren't ready to discard your mattress, you may find that a cooling mattress pad is your ideal solution.
Cooling mattress pads are essentially mattress toppers made from materials such as latex or gel-infused foam. They work by absorbing the extra heat and helping to regulate your body temperature. You just need to position the pad on top of your mattress, make your bed as usual, and look forward to a cooler, more comfortable sleep.
The only downside to these is the sizing. We have found that they tend to stop a little short of the edges of our mattress, which can make you feel as though you've lost an inch or two of bed space.
A cooling mattress, on the other hand, is infused with materials that will stop your body heat from getting trapped and ultimately radiating back at you, causing you to overheat. As these mattresses have the cooling material within them, you won't feel like you're losing mattress space. However, they are naturally more expensive, so your budget will come into play here.
Cooler sleep tips
Tips for staying cool as you sleep
It's tempting to leave the window as you sleep, right? Well, this is fine if you live in an area that's relatively free of pollution and noise disturbances, but if you live on a road that's busy with traffic and people, it could make your sleep worse.
Instead, consider investing in one of the best smart thermostats to keep your bedroom at the optimal temperature for sleep - between 60-65°F. Or you may prefer to use a cooling tower fan or an air conditioner to create the perfect in-room temperature. Closing your curtains or blinds during the day will also stop heat from building up in the room and in your mattress.
You could also take a cool shower before bed and use a mint-based soap or shower gel to double-down on the cooling effects.
Elsewhere, in addition to avoiding caffeine after midday where possible, try to avoid any foods or drinks that raise your core body temperature before bed. Alcohol is a no-no, as it can cause night sweats and lead to you waking up feeling parched.
