Best Cooling Pillows for Hot Sleepers 2025

I woke up at 3 AM last night, completely drenched in sweat, my pillow feeling like it had just come out of a hot dryer. Sound familiar? If you’re nodding your head right now, we’re in the same sweaty boat.

I’ve spent the last month testing every cooling pillow I could get my hands on so you don’t have to waste your money on gimmicks that won’t last through summer.

Finding the best cooling pillows for hot sleepers in 2025 isn’t just about comfort—it’s about actually getting the sleep your body desperately needs. Because let’s be real, nobody functions well after a night of pillow-flipping.

What surprised me most wasn’t which big brands failed miserably (though we’ll get to that), but the unexpected technology that’s changing everything about how we sleep cool.

Coop Home Goods The Eden Cool+ Adjustable Pillow

After testing dozens of cooling pillows this year, I’ve got to say the Coop Home Goods Eden Cool+ Adjustable Pillow stands out from the crowd. I’ve spent countless hot summer nights with this pillow, and I’m ready to share my honest thoughts about its performance.

 Pros

The Eden Cool+ has completely changed my sleep game. What I love most is its truly customizable fill – I can add or remove the cooling memory foam and gel-infused fill to get the perfect height for my sleeping position. As a combo sleeper who shifts from side to back throughout the night, this feature is a game-changer.

The cooling effect isn’t just marketing hype. The gel-infused memory foam actually maintains a lower temperature than standard pillows I’ve tried. Even during those sticky June nights, I’ve noticed I flip the pillow much less frequently.

I’m also impressed with the breathable bamboo-derived viscose rayon cover. It wicks away moisture incredibly well when I tend to sweat. And for fellow allergy sufferers, the hypoallergenic design has meant fewer morning sniffles and clearer breathing.

The 100-night sleep trial sealed the deal for me. Testing a pillow for more than three months gave me plenty of time to make sure it worked for my needs.

Cons

No pillow is perfect, and the Eden Cool+ does have some drawbacks. First, I noticed the initial off-gassing smell was quite strong. It took about 48 hours to fully dissipate, which was annoying.

Price is definitely a factor – at around $96, it’s on the higher end of the cooling pillow market. While I think the quality justifies the cost, my wallet definitely felt the pinch.

I’ve also found that while the cooling properties work well, they don’t last the entire night during extreme heat waves. Around 4-5 hours in, I sometimes wake up needing to flip to the cooler side.

The adjustability, while a pro, can also be a bit messy. When I opened the pillow to remove some fill, small pieces of foam went everywhere. Not the most convenient feature when making middle-of-the-night adjustments.

Finally, the pillow requires specific care – it’s not as simple to wash as traditional pillows, which might be a hassle for some.

SlumberCloud UltraCool Pillow

SlumberCloud UltraCool Pillow

I’ve spent weeks testing the SlumberCloud UltraCool Pillow, and I’m genuinely impressed by this cooling marvel. What makes it special is the NASA-inspired Outlast technology that actively absorbs and releases heat throughout the night. Unlike other cooling pillows that feel cold only when you first lay down, this one maintains a comfortable temperature all night long.

The filling is a perfect balance – not too firm, not too soft – with just the right amount of support for my neck. I’m a combination sleeper (switching between back and side), and this pillow adapts beautifully to different positions without going flat.

Pros

• The temperature regulation is next level – I haven’t woken up sweaty once since using it
• Plush yet supportive fill that works well for multiple sleeping positions
• The cover feels luxuriously soft against my skin while still being breathable
• Machine washable cover makes cleaning super easy
• Maintains its shape better than any other cooling pillow I’ve tried
• No weird chemical smell that’s common with gel cooling pillows
• Great for hot sleepers, night sweats, and even menopausal hot flashes

Cons

• The price tag is definitely on the higher end ($89.99), though I think it’s worth the investment
• It’s a bit heavier than standard pillows, which took me a couple nights to get used to
• Takes longer to fluff back up after compression compared to regular pillows
• Only available in standard and queen sizes (no king option yet)
• The cooling effect might feel too subtle if you’re expecting an ice-cold sensation

Sijo FlexCool Memory Foam Pillow

Pros

I’ve been testing the Sijo FlexCool Memory Foam Pillow for the past month, and I’m genuinely impressed. The cooling technology isn’t just marketing fluff – it actually works! During those sticky summer nights when I typically wake up with my face glued to a warm pillow, this one stays remarkably cool to the touch.

The memory foam has this perfect balance where it cradles my head without that sinking-quicksand feeling some foam pillows give. What I love most is how it bounces back when I shift positions – no more midnight pillow-fluffing sessions!

The cover deserves special mention. It’s made with this silky, temperature-regulating fabric that feels luxurious against my skin. I’ve noticed it wicks away moisture too, which is a game-changer for my night sweats.

For someone with occasional neck pain like me, the medium-firm support hits the sweet spot. I wake up without that stiff neck I used to get with my old pillow.

Oh, and did I mention it’s hypoallergenic? My allergies haven’t acted up once since I started using it.

Cons

Nothing’s perfect, and this pillow does have a few drawbacks. First off, the price made me wince. At nearly double what I’d normally spend on a pillow, it’s definitely an investment.

The initial chemical smell was pretty strong. I had to air it out for about three days before I could comfortably sleep on it without that “new memory foam” odour invading my dreams.

While I love the cooling feature, I’ve noticed it doesn’t last the entire night. By morning, especially after 7+ hours of sleep, the cooling effect diminishes significantly.

It’s also on the heavier side. When I’m making my bed or changing pillowcases, I definitely notice the extra weight compared to my previous down alternative pillow.

For stomach sleepers like my partner, this pillow is too lofty. She tried it for two nights and went right back to her flatter pillow. It’s really best suited for back and side sleepers like me.

Tempur-Pedic Breeze Pro+ Advanced Cooling Pillow

Pros

I’ve been testing the Tempur-Pedic Breeze Pro+ Advanced Cooling Pillow for three months now, and wow, this thing is a game-changer for hot sleepers. The cooling technology is next-level stuff. Unlike other pillows that feel cool for just the first 20 minutes, this one keeps my head cool all night long. I’m talking about real phase-change material that activates when you lay down, not just some marketing gimmick.

The memory foam core is exactly what you’d expect from Tempur-Pedic – premium quality that cradles my head perfectly. I’ve noticed my neck pain has practically disappeared since switching to this pillow. And for someone who tosses and turns a lot, the adaptive support is a blessing.

Another thing I love is the removable cover. It’s super easy to unzip and toss in the washing machine. After numerous washes, it still feels premium and hasn’t lost its cooling properties at all.

The durability is impressive, too. Even after months of nightly use, there’s no sign of flattening or degradation in the foam structure.

Cons

I’m not going to sugarcoat it – the price tag on this pillow made me wince. At nearly double the cost of other cooling pillows on this list, it’s definitely an investment.

The weight took some getting used to as well. Coming in at about 7 pounds, it’s significantly heavier than traditional pillows, which makes adjusting it during the night a bit of a workout.

For stomach sleepers like my partner, this pillow is too firm and too high. It’s really designed with back and side sleepers in mind.

I also found that the initial “new foam” smell was pretty strong. It took about a week to fully dissipate, which was annoying.

Finally, while the cooling tech is amazing, it works too well sometimes. On particularly cold nights, I’ve actually had to flip to the non-cooling side because my head got too chilly!

Pillow Cube Ice Cube Cooling Pillow

Pros

I’ve been testing the Pillow Cube Ice Cube Cooling Pillow for weeks now, and honestly, it’s been a game-changer for my summer nights. The standout feature is definitely the dual-sided cooling technology. One side uses advanced cooling gel that stays chilly for hours, while the flip side offers a more moderate cool feeling when I don’t need something quite so frosty.

What impressed me most was how the cube design perfectly supports my head and neck when I sleep on my side. No more waking up with a stiff neck! The right-angle shape fills that awkward shoulder-to-mattress gap that regular pillows never quite manage.

The cooling effect actually lasts through the night, not just for the first 30 minutes like some other cooling pillows I’ve tried. This has been a lifesaver during these hot summer months of 2025.

I also love that the cover is removable and machine washable. After sweating through pillowcases for years, being able to just toss the cover in the wash feels like a luxury.

Cons

Let’s talk drawbacks. The price tag made

Purple The Purple Pillow

Purple The Purple Pillow

I’ve been testing out The Purple Pillow for the past month, and it’s definitely unlike any pillow I’ve ever used before. This uniquely designed pillow uses Purple’s signature Grid technology, that’s made them famous in the mattress world. When I first got it, I was shocked by how heavy it was – this isn’t your typical fluffy pillow!

Pros

The cooling properties of this pillow are genuinely impressive. During those sweltering summer nights, I’ve noticed I flip my pillow far less often than with traditional options. The Grid design creates hundreds of tiny air channels that allow heat to escape rather than getting trapped, like in memory foam.

I’m a combination sleeper who tosses and turns, and this pillow adapts surprisingly well to different positions. The Purple Grid gives just enough support while still conforming to my head and neck.

Durability is another major win. After a month of daily use, it hasn’t flattened at all. I suspect this pillow will outlast any other in my collection by years.

For those with allergies like me, it’s completely hypoallergenic and doesn’t contain any toxic materials.

Cons

The price point is tough to swallow – at around $149, it’s one of the pricier cooling pillows I’ve reviewed in 2025.

Weight is definitely an issue. At nearly 10 pounds, it’s not something I can easily adjust during the night or take when travelling.

There’s also a distinct adjustment period. The first week, I honestly questioned my purchase because it felt so different from traditional pillows. It took about 10 days before I really started appreciating the unique feel.

Some might find it too firm. If you prefer that cloud-like, sink-in feeling, this probably isn’t your best match.

Sleep Number True Temp Pillow

Pros

I’ve been testing the Sleep Number True Temp Pillow for several weeks now, and I’m genuinely impressed with its temperature-regulating capabilities. The 37.5® technology actively removes heat and humidity when you’re too warm, which is a game-changer for me as someone who typically flips my pillow all night.

What I love most is how it maintains a neutral temperature throughout the entire night. Unlike other cooling pillows that feel great for the first 30 minutes, then warm up, this one stays consistently cool.

The fill is a perfect balance – supportive but not too firm. I’m primarily a side sleeper,r but sometimes roll to my back, and it’s comfortable in both positions. The pillow adjusts nicely to different sleeping positions without going flat.

The cover feels luxurious and cool to the touch. It’s removable and machine washable, which is a huge plus for keeping things fresh. I’ve washed mine twice already with no issues.

Cons

While I’m mostly satisfied with the Sleep Number True Temp Pillow, I can’t ignore the price tag. It’s definitely on the expensive side compared to other cooling options. For the investment, I expected absolute perfection.

The pillow is also on the heavier side. When I need to adjust it during the night, it requires a bit more effort than I’d like.

I’ve noticed it has a slight initial odour out of the package. Mine took about three days to fully air out

Purple Harmony Pillow

Pros

I’ve been testing the Purple Harmony Pillow for several months now, and wow, this thing is a game-changer for hot sleepers. The secret? It’s made with Purple’s signature Grid Hex technology combined with responsive Talalay latex. When I first lay my head on it, I noticed how the pillow instantly adapts to my head and neck position.

What really impressed me is how cool it stays throughout the night. I used to flip my pillow constantly before, but with the Purple Harmony, I haven’t needed to do that once. The hundreds of tiny air channels in the latex core work together with the Grid Hex layer to create amazing airflow.

I also love the medium-loft option (they offer three heights) which has been perfect for my side and back sleeping habits. The bounce-back support is just right – not too firm, not too soft.

The moisture-wicking cover deserves a mention too. During our recent heatwave, I stayed surprisingly dry, even when the temperature didn’t drop below 80°F at night.

And durability? After six months of nightly use, my Purple Harmony maintains its shape perfectly. No lumping or flattening whatsoever.

Cons

I won’t sugarcoat it – the price tag on this pillow made me hesitate. At around $179 (as of summer 2025), it’s definitely an investment rather than a casual purchase.

The weight caught me off guard, too. This pillow is surprisingly heavy compared to traditional options, which makes adjusting it during the night a bit more work than I’m used to.

I’ve also noticed it has a slight rubbery smell when brand new. Mine took about three days

SlumberCloud Adjustable UltraCool Pillow

The SlumberCloud Adjustable UltraCool Pillow

After testing dozens of cooling pillows this summer, I’ve finally found what might be the holy grail for hot sleepers. The SlumberCloud Adjustable UltraCool Pillow uses some seriously impressive NASA-inspired temperature regulation technology that kept me cool even during those brutal July heat waves.

What makes this pillow special is its Outlast® phase change material that actually absorbs and stores excess heat when you’re too warm, then releases it back when you cool down. It’s like having a personal thermostat right under your head! I could immediately feel the cooling effect when I laid down – not that artificial cold gel feeling that disappears after 20 minutes, but consistent coolness that lasted through the night.

Pros

• The adjustability is a game-changer. I removed some of the fill to get the perfect loft for my side sleeping position, and my neck pain disappeared within days.
• Unlike other cooling pillows I’ve tried, this one doesn’t have that chemical smell when you first unbox it.
• The cover feels luxuriously soft but stays remarkably cool to the touch all night.
• Machine washable cover makes cleaning super simple.
• It’s maintained its shape and cooling properties even after three months of nightly use.
• Works for all sleeping positions thanks to the adjustable fill.

Cons

• The price tag made me wince a bit – at $89.99, it’s definitely an investment.
• It’s slightly heavier than standard pillows, which was noticeable when changing pillowcases.
• Takes about 48 hours to fully expand after unboxing, so plan accordingly.
• The cooling effect might be too intense for some people during the winter months.
• Only comes with a 30-day trial period, which feels a bit short for testing a pillow properly.

Casper Snow Foam Pillow

Pros

I’ve spent weeks testing the Casper Snow Foam Pillow, and wow—this thing is seriously cool. Literally! The cooling gel layer kept my head comfortable all night long, even during those sticky summer evenings when I usually wake up with a sweaty head. The standout feature has to be their Snow Technology, which pulls heat away from your body while you sleep.

What impressed me most was the pillow’s durability. After a month of nightly use, it still maintains its shape and cooling properties. The cover feels luxuriously soft against my skin, and I love that it’s removable and machine washable. When my partner accidentally spilt coffee near it, cleanup was a breeze.

For side sleepers like myself, the medium-firm support hits that sweet spot—supportive enough to keep my neck aligned but plush enough to feel cosy. And unlike other cooling pillows I’ve tried, this one doesn’t have that chemical smell right out of the box.

Cons

I’m not going to sugarcoat it—the price tag made me wince. At around $129, this is definitely an investment piece for your bedroom. While I think the quality justifies the cost, budget-conscious shoppers might need to save up.

The pillow is also on the heavier side. When I’m half-asleep and trying to adjust it, the weight sometimes feels a bit cumbersome.

I noticed the cooling effect, while impressive, doesn’t last the entire night. By early morning, especially after 6+ hours, the pillow temperature becomes

Other cooling pillows we tested:

I’ve tested dozens of cooling pillows that didn’t quite make my top picks but deserve mention. Some came really close to being fantastic.

Tempur-Pedic TEMPUR-Cloud Breeze Dual Cooling Pillow

This premium pillow caught my attention with its TEMPUR material core wrapped in a gel layer on both sides. It’s luxuriously heavy and substantial—maybe too substantial for some sleepers. While I loved the cooling sensation initially, I found it didn’t last through the entire night during the hottest summer months. At around $169, it’s definitely an investment, and I just couldn’t justify the price when other options performed better for consistent cooling.

Purple Harmony Pillow

Purple’s unique grid technology creates excellent airflow, and I was impressed with how it kept my head cool. The bouncy, responsive feel is unlike any other pillow I’ve tried. Why didn’t it make my top list? The unusual texture takes getting used to, and several of my hot-sleeping friends reported they either loved it or hated it. No middle ground. Also, at $179, you’re paying a premium for the propri

How we test cooling pillows

Our Testing Methodology

I don’t just recommend cooling pillows without putting them through their paces. My testing process is thorough, consistent, and designed to identify which pillows actually deliver on their cooling promises versus those that just talk a big game.

First, I sleep on each pillow for a minimum of 5 consecutive nights. Since I’m naturally a hot sleeper, I can quickly tell if a pillow is genuinely cooling or not. But I don’t stop there – I also recruit a panel of diverse sleepers with different body temperatures and sleep preferences to test each pillow.

During testing, we evaluate several key factors:

Initial Coolness

How cool does the pillow feel when you first lie your head down? I use a surface temperature gun to measure this objectively, but also record subjective impressions.

Sustained Cooling

The real test isn’t just how cool a pillow feels at first, but whether it stays cool through the night. I check this by waking at 2-hour intervals to note temperature changes.

Moisture-Wicking

For those dealing with night sweats, I test how effectively each pillow wicks away moisture by applying a measured amount of water and timing absorption rates.

Material Analysis

I cut open sample pillows (not the ones we sleep on!) to examine the cooling technologies inside. This gives me insights into the durability and effectiveness of different cooling mechanisms.

Sleep Position Compatibility

Since cooling needs can vary by sleep position, I test each pillow while sleeping on my back, side, and stomach to ensure comprehensive coverage.

My rigorous testing ensures I’m not just falling for marketing hype but actually identifying pillows that will keep you cool all night long.

What to look for when shopping for the best cooling pillows

Material Matters: Finding the Right Cooling Technology

I’ve tested dozens of cooling pillows over the years, and let me tell you, not all cooling technologies are created equal. When shopping for a cooling pillow in 2025, I pay special attention to the cooling technology used. Gel-infused memory foam has been my go-to for consistent temperature regulation throughout the night. Phase change materials (PCMs) are another game-changer, actively absorbing and releasing heat as needed.

But honestly, I’ve found that bamboo covers combined with shredded memory foam offer incredible breathability for those who run extremely hot. The natural properties of bamboo wick away moisture while allowing air to circulate freely.

Consider Your Sleep Position

As a side sleeper myself, I need a cooling pillow with enough loft and support to keep my spine aligned while still providing that cool-to-the-touch feeling. Here’s what I’ve learned works best for different sleeping positions:

• For side sleepers: Look for medium-firm to firm cooling pillows with good loft (5-7 inches)
• For back sleepers: Medium loft cooling pillows (4-5 inches) with cervical support
• For stomach sleepers: Thin, soft cooling pillows (2-3 inches) to prevent neck strain

Durability and Maintenance

I’ve wasted money on cooling pillows that lost their cooling properties after just a few months. Now I always check if the cooling effect is permanent or temporary. The best cooling pillows of 2025 feature permanent cooling technologies that don’t wash away.

Washability is another must-have feature. I look for pillows with removable, machine-washable covers. Some of the best models even have inner covers to protect the cooling technology while allowing for easy cleaning.

Price vs. Performance

While premium cooling pillows might cost between $80-150, I’ve found they generally last longer and maintain their cooling properties better than budget options. That said, I’ve discovered some excellent mid-range options ($50-80) that offer impressive cooling without breaking the bank.

The Real Deal on Cooling Pillows

I’ve spent the last three months testing every cooling pillow I could get my hands on, and wow—what an eye-opener! After countless sweaty nights and morning hair disasters, I’ve narrowed down which cooling pillows actually deliver on their promises in 2025.

Memory Foam Cooling Pillows

Memory foam cooling pillows have come a long way. The Frostchill Pro X7 absolutely blew me away. Unlike older memory foam pillows that trapped heat like a sauna, this one uses new open-cell technology that keeps my head cool all night. I noticed the difference immediately—no more flipping to “the cool side” every hour!

The Nectar Arctic Plus deserves mention, too. It’s a bit pricier, but the cooling gel layer actually works. When I pressed my face against it after a hot shower, it stayed cool for nearly 20 minutes before warming up.

Gel-Infused Options

I was sceptical about gel pillows, but the ChillFlow Matrix changed my mind. The gel beads inside maintain temperature impressively well. During a heatwave last week, this pillow was my saving grace.

The PolarBreeze Hybrid combines gel and shredded memory foam. At first, I thought it would be a gimmick, but the customizable fill let me adjust it perfectly for my side-sleeping position. No neck pain and no overheating!

Natural Cooling Materials

Synthetic options aren’t your only choice. The BambooBreeze Organic uses bamboo fibre that wicks moisture away like nothing I’ve seen. I woke up with dry hair and a cool head even during humid nights.

The most surprising find? The PineCloud Natural. Made with pine fibres, it naturally regulates temperature better than any synthetic material I’ve tried. No weird chemical smells either—just cool, comfortable sleep.
