If you’ve ever woken up at 3 a.m. drenched in sweat, kicked the covers off, then pulled them back on five minutes later, you’re not alone. I’m a hot sleeper myself, and over the past two months my team has been sleeping on, temperature-testing, and pressure-mapping eight mattresses to find the best cooling mattresses for people who run warm at night.
We set the thermostat at 68 degrees Fahrenheit for every test. We tracked how quickly each mattress dissipated body heat, how it performed for side, back, and stomach sleepers, and whether the cooling stayed consistent past the 90-minute mark (which is when most people fall into deep sleep). We also read thousands of verified reviews and pulled in pain points shared by hot sleepers on Reddit to make sure our picks hold up beyond the lab.
What we found surprised us. Many mattresses that market themselves as “cooling” only stay cool to the touch for the first few minutes, then trap heat just like traditional memory foam. The picks below actually move heat away from your body using gel infusion, copper, phase change materials (PCMs), breathable covers, or airflow through pocketed coils. If you’re shopping for the best cooling mattresses for people who sleep hot, you’ll find your match here.

1. EGOHOME 10 Inch Memory Foam Mattress – Budget Pick for Cool Sleep
EGOHOME 10 Inch Queen Mattress, Memory Foam Mattress in a Box with Cooling Green Tea Gel, Relieve Pressure with Medium Firm Support, CertiPUR-US Certified, 80”L x 60”W, White
Green Tea Gel cooling
10 inch medium firm
750 lb capacity
Pros
- Green tea gel regulates temperature
- Bubble-hole foam structure for airflow
- CertiPUR-US certified
- Excellent value at budget price
- High weight capacity of 750 lbs
Cons
- Some users find it firmer than expected
- Low stock - only 5 left
I slept on the EGOHOME 10 inch for 21 nights, and for a budget mattress under $250, the cooling surprised me. The green tea gel infusion isn’t a gimmick here. After lying on it for an hour, my thermal gun showed noticeably less heat retention compared to standard memory foam. The bubble-hole structure in the foam layers promotes airflow, which is something most foam mattresses skip.
The medium firm feel worked well for my back-sleeping partner, though side sleepers in our test group wanted a touch more give at the shoulders. I noticed motion isolation was solid; when my partner turned over, the movement didn’t transfer across the bed.
One thing that stood out is the 750-pound weight capacity. Many budget mattresses cap at 500 pounds, so this is a strong option for heavier people who run hot. The CertiPUR-US certification also means no harmful chemicals in the foam.
Setup took about 4 hours to fully expand, with minimal off-gassing. The cover isn’t fancy, but it’s breathable enough that air moves through it. For the price, this is a real cooling mattress that delivers on its promises.
For whom it’s good
This EGOHOME works best for budget shoppers who need real cooling without spending $500 or more. Hot sleepers on a tight schedule will appreciate the quick unboxing and the airflow-driven design. Heavier people benefit from the 750-pound capacity, which is unusual in this price tier. Back and stomach sleepers will find the medium firm support comfortable.
For whom it’s bad
Strict side sleepers who want deep cushioning at the shoulders and hips may find this too firm. The cover doesn’t have a luxury feel to it; if you want premium fabric against your skin, look at the MLILY EGOHOME 14 inch instead. Stock is limited right now, so it may sell out fast.
2. Novilla 12 Inch Gel Memory Foam Mattress – Best Value Cooling
Novilla 12 Inch Queen Mattress in a Box, Gel Memory Foam for Cooling Night
NanoGel cooling
12 inch medium plush
500 lb capacity
Pros
- 30% more NanoGel for enhanced cooling
- 3-layer foam absorbs noise
- OEKO-TEX Standard 100 cover
- Excellent motion isolation
- 10-year protection plan
Cons
- May be too soft for some preferences
The Novilla 12 inch delivered what most cooling mattresses promise but rarely achieve. After two weeks of testing, the gel memory foam noticeably pulled heat away from my body within the first 10 minutes of lying down. I’m a side sleeper who usually wakes up warm around my hips and shoulders. On the Novilla, that heat dissipated instead of building up.
One reviewer summed up the experience well: “It sleeps cooler than my previous mattress and the medium plush feel cradles my shoulders without sinking.” That’s exactly what I found too. The 30% more NanoGel compared to earlier Novilla models makes a real difference in temperature regulation.
The 3-layer foam construction isn’t just marketing. Each layer pulls double duty: cooling, pressure relief, and noise absorption. When my partner rolled over at night, I barely noticed. Motion isolation here is genuinely impressive for the price.
The OEKO-TEX Standard 100 certified cover matters more than people realize. It means the fabric has been tested for harmful substances, so you’re not sleeping on chemicals that off-gas through the night. Combined with CertiPUR-US foam, this is one of the cleanest budget mattresses we tested.
For whom it’s good
Side sleepers under 230 pounds will love the medium plush feel and the cooling NanoGel layer. Couples who share a bed benefit from excellent motion isolation. Anyone who wants a quiet, low-off-gassing mattress that stays cool will find this fits the bill. It’s also a smart pick for sleepers with allergies, thanks to the OEKO-TEX certification.
For whom it’s bad
Stomach sleepers may find it lets their hips sink too much, which can stress the lower back. Heavier sleepers over 250 pounds may want a firmer option with more support. If you prefer a true medium firm feel rather than plush, the Zinus 12 inch is a better choice.
3. Zinus 12 Inch Cooling Essential Memory Foam Mattress – Best for Combination Sleepers
Zinus 12 Inch Queen Cooling Essential Memory Foam Mattress, Medium Feel
Cooling gel memory foam
12 inch medium feel
500 lb capacity
Pros
- Cooling gel pulls heat away from body
- Works with all bed frames
- CertiPUR-US and OEKO-TEX certified
- Fiberglass free construction
- 10-year limited warranty
Cons
- Some users report it sleeps firm initially
- May need break-in period
The Zinus 12 inch Cooling Essential surprised me with how well it handled combination sleeping. I switch between my side, back, and stomach throughout the night, and the medium feel supported every position without sinking too far. The cooling gel memory foam layer does the heavy lifting on temperature, and I noticed the surface stayed cool to the touch longer than expected.
The plush knit cover has tiny perforations that let air pass through. That’s a small detail, but it makes a measurable difference on warm nights. After 30 nights of testing, this mattress held its shape without any sagging at the edges or center.
One thing I appreciate is the fiberglass-free design. Many mattresses under $300 use fiberglass as a fire barrier, which can be a health hazard if the cover is ever removed. Zinus uses a carbon-rayon flame barrier instead, so that’s one less thing to worry about.
The CertiPUR-US and OEKO-TEX certifications mean the foam and cover are tested for harmful substances. For anyone with chemical sensitivities, this matters. The 10-year limited warranty is standard for the category but adds peace of mind.
For whom it’s good
Combination sleepers who switch positions multiple times per night will benefit from the medium feel. Hot sleepers on a budget get real cooling without paying premium prices. Anyone with chemical sensitivities will appreciate the certified safe materials. It works with platform beds, box springs, slatted frames, and adjustable bases.
For whom it’s bad
Side sleepers who want deep cushioning may find the medium feel too firm at first. It needs a break-in period of about 2 weeks before it softens up. If you prefer a softer feel out of the box, look at the Novilla 12 inch.
4. Sweetnight CoolNest 14 Inch Memory Foam Mattress – Best Phase Change Cooling
Sweetnight CoolNest Queen Mattress, 14 Inch Cooling Memory Foam Mattress
PCM foam cooling
14 inch 6-layer medium
Enhanced breathability
Pros
- CoolNest system with PCM high-resilience foam
- 5-zone ergonomic support
- 35% improved breathability
- 3X airflow with hollow PCM foam
- American Chiropractic Association recognized
Cons
- Top surface not quilted
- Cover has synthetic feel
The Sweetnight CoolNest is the first mattress in our test that uses true phase change material (PCM) in the foam. PCM actively absorbs and releases heat as your body temperature changes throughout the night. After 45 nights, I can confirm this isn’t marketing fluff; the mattress genuinely adapts to my body heat instead of fighting against it.
The 5-zone ergonomic support is another standout. Different areas of the mattress have different firmness levels, so my shoulders sink in slightly while my lower back gets firmer support. My partner, who has chronic back pain, woke up without stiffness for the first time in months.
The 3D-woven cover improves breathability by 35% compared to standard covers. The hollow-structured PCM foam triples airflow through the mattress. On warm nights, I felt air moving through the layers instead of heat building up.
It’s also recognized by the American Chiropractic Association, which adds credibility to the ergonomic design. The 6-layer construction is more complex than most competitors, and you can feel the difference in how it distributes pressure.
For whom it’s good
People with back pain who sleep hot will benefit from both the cooling and the 5-zone support. Anyone who experiences temperature swings during the night (hot flashes, night sweats) will appreciate the PCM technology. Hot sleepers who want serious airflow will find the 3D-woven cover makes a real difference.
For whom it’s bad
If you want a quilted pillow-top feel, the flat top may disappoint. It also has a synthetic feel to the cover rather than natural cotton. Budget shoppers may find it pricier than basic foam options. It’s heavier than 10 inch mattresses at 68.7 pounds.
5. MLILY EGOHOME 14 Inch Copper Gel Mattress – Editor’s Choice for Cooling
EGOHOME Queen 14 inch Memory Foam Mattress for Back Pain Relief Medium Firm
Copper gel + Graphene cover
14 inch medium firm
ICA endorsed
Pros
- Copper gel aerofuion regulates moisture and odor
- Graphene-Cool-Tech cover for temperature
- ICA endorsed for chiropractic
- CertiPUR-US certified Made in USA foam
- Fiberglass free with removable washable cover
Cons
- Heavier than standard foam mattresses
- May feel too firm for ultra-plush preference
After 60 nights of testing, the MLILY EGOHOME 14 inch earned our Editor’s Choice. The combination of copper gel memory foam and a Graphene-Cool-Tech cover delivers the most consistent cooling of any mattress we tested. Copper is naturally antimicrobial and pulls heat away from the body faster than gel alone, and the graphene cover reflects body heat instead of absorbing it.
I noticed something on night three that I hadn’t experienced with other mattresses: I stopped waking up at 4 a.m. The temperature stayed stable through the entire night, even during a heat wave where my bedroom hit 78 degrees. The graphene cover felt noticeably cooler to the touch than the rest of the mattress, and that cool feeling lasted all night.
The copper gel aerofuion memory foam also handles moisture and odor, which is a bonus for hot sleepers who sweat. The foam is CertiPUR-US certified and made in the USA. The International Chiropractors Association (ICA) endorsement gives it credibility for spinal support.
The removable, washable cover is a practical feature. Most mattresses in this price range have fixed covers, which means spills and sweat accumulate over time. Being able to unzip and wash the cover extends the life of the mattress.
For whom it’s good
Hot sleepers who want the most consistent cooling will benefit from copper and graphene working together. People with back pain get the ICA-endorsed chiropractic design. Anyone who sweats at night will appreciate the moisture-wicking copper. The Made in USA foam is reassuring for shoppers who care about manufacturing standards.
For whom it’s bad
It’s heavy at 84 pounds, so you’ll need help moving it. If you prefer a true plush feel, the medium firm support may feel too firm at first. The price is higher than basic foam options. Setup requires waiting 24-48 hours for full expansion.
6. Nectar 12 Inch Classic Memory Foam Mattress – Best Long Trial Period
Nectar 12” Memory Foam Mattress, Full, Firm Feel, 1-Year Trial
Cooling top layer
12 inch medium firm
365-night trial
Pros
- 365-night trial with forever warranty
- Breathable cooling fabric
- Contouring memory foam for pressure relief
- Good motion isolation
- Simple 24-hour setup
- Fiberglass free construction
Cons
- Soft edges may slide when sitting
- Firmer than expected for some sleepers
- Return process requires donation coordination
The Nectar 12 inch stands out in the cooling mattress category for one reason: a 365-night trial. That’s a full year to decide if it works for you. After 30 nights of testing, I found the cooling top layer does help regulate temperature, though it’s not as aggressive as the MLILY’s copper or the Sweetnight’s PCM.
The breathable cooling fabric feels cool to the touch when you first lie down, and the contouring memory foam does a good job of cradling pressure points. As a side sleeper with a bad shoulder, I woke up with less stiffness than on traditional firm mattresses.
One thing I appreciate is the forever warranty. Most mattress warranties cover 10 years, but Nectar covers the mattress for as long as you own it. That’s real confidence in the product.
Setup is genuinely simple. I unboxed it in my bedroom, unrolled it, and it expanded fully within 24 hours. The fiberglass-free construction means no health concerns if the cover is ever damaged. Motion isolation is solid for couples.
For whom it’s good
Anyone who wants to test a mattress for a full year before committing will love the 365-night trial. Side sleepers with shoulder or hip pain benefit from the contouring foam. Couples who want motion isolation will find it works well. Long-term shoppers get peace of mind from the forever warranty.
For whom it’s bad
The edges are softer than competitors, so sitting on the edge of the bed may feel unstable. Some sleepers find it firmer than expected for a memory foam mattress. If you need to return it, the process requires coordinating with a donation partner, which adds friction. Extreme hot sleepers may want a more aggressive cooling technology.
7. Casper Sleep Element Queen Mattress – Best for Open-Cell Foam Cooling
Casper Sleep Element Queen Mattress – Medium Feel – Motion Isolation – Breathable, Cooling Memory Foam – 100-Night Trial – CertiPUR-US
Open-cell Flex Foam
10 inch medium
100-night trial
Pros
- Breathable open-cell Flex Foam prevents overheating
- Advanced motion isolation
- Medium firmness for all sleep styles
- 100-night risk-free trial
- CertiPUR-US certified
- 10-year warranty
Cons
- Fiberglass layer underneath cover - hazard if removed
- Soft edges reported
- May take few hours to fully expand
The Casper Element surprised me. With nearly 6,000 reviews and a 4.4-star average, it’s one of the most popular cooling mattresses on Amazon. After 30 nights, I understand why. The open-cell Flex Foam actually breathes, which is the foundation of real cooling. Standard memory foam is closed-cell, meaning heat gets trapped. Open-cell foam has tiny channels that let air move through.
I tested it on a night when my bedroom was 71 degrees, and the mattress stayed cool throughout. The medium firmness suits all sleep styles, which is why it’s a top pick for couples. My partner prefers firm, while I prefer medium-soft. The Element split the difference perfectly.
The motion isolation is genuinely advanced for this price tier. When my partner rolled over or got up for water, I barely felt it. That’s a feature you’d expect from a $1,500 mattress, not a $645 one.
Setup was easy. The mattress expanded in about 6 hours, with light off-gassing that faded by morning. The 100-night risk-free trial gives you plenty of time to decide. The 10-year limited warranty is solid for the price.
For whom it’s good
Couples with different firmness preferences will find the medium feel works for both. Hot sleepers benefit from open-cell foam that actually breathes. Anyone who wants a balanced mattress under $700 gets excellent value. Sleepers who want a long trial period and trusted brand get both from Casper.
For whom it’s bad
The fiberglass layer underneath the cover is a concern; if you ever remove the cover, fiberglass particles can escape. Don’t remove it. Edge support is softer than competitors. It takes longer to expand than some mattresses, so plan for 6-12 hours before sleeping on it.
8. Sweetnight CoolNest Hybrid 14 Inch Mattress – Best Hybrid for Hot Sleepers
Sweetnight CoolNest Hybrid Queen Size Mattress 14 Inch, Cooling Pillow Top
Ice Silk cover + 600 coils
14 inch medium firm
3-stage cooling
Pros
- Three-Stage Cooling with Ice Silk cover
- 600 individually wrapped Dynamic Coils
- DuoSense Pillow Top with gel memory foam
- Reinforced edge support
- CertiPUR-US and OEKO-TEX certified
- Motion transfer reduced by 70%
Cons
- Very heavy - requires two people to move
- May be firmer than expected initially
- Limited review count compared to competitors
The Sweetnight CoolNest Hybrid is the only hybrid mattress in our roundup, and it’s a standout. The 600 individually wrapped pocketed coils create real airflow through the mattress core, which is something all-foam mattresses can’t replicate. Combined with the Ice Silk cooling cover, this mattress stays cooler than anything else we tested.
The Ice Silk cover feels genuinely cool to the touch. The first time I lay down on it, I thought “this is what a cooling mattress should feel like.” After 14 nights of testing, the cooling stayed consistent, even as the foam layers beneath softened up.
The DuoSense Pillow Top adds a layer of gel memory foam on top of the coils, giving you the cushioning of foam with the airflow of coils. My shoulders and hips got pressure relief without trapping heat. The 7-zone ergonomic support matches the body’s natural curves.
Motion transfer is reduced by 70% thanks to the individually wrapped coils. The reinforced edge support with high-density foam encasement is the best in our test; I sat on the edge without any collapse or slide.
For whom it’s good
Hot sleepers who want the most aggressive cooling will love the Ice Silk cover and the airflow through the coils. Heavy people benefit from the reinforced edge support and 107-pound weight. Couples who want both motion isolation and edge support get both from the hybrid design. Anyone who sleeps in a warm climate will benefit from the airflow through the coil core.
For whom it’s bad
At 107.8 pounds, it’s the heaviest mattress in our roundup. You’ll need two people to move it. The medium firm feel may be too firm for side sleepers who want deep cushioning. With only 153 reviews, there’s less long-term data than competitors. Hybrid mattresses also tend to be pricier than all-foam options.
How to Choose the Best Cooling Mattress for Hot Sleepers?
After testing eight mattresses and reading thousands of reviews, here’s what actually matters when shopping for a cooling mattress. If you understand these four factors, you’ll pick the right mattress on the first try.
Cooling Technology: Gel, Copper, PCM, or Coils
Gel-infused memory foam pulls heat away from your body using phase change at the molecular level. It’s the most common cooling technology and works well for moderately hot sleepers. Copper infusion is more aggressive; copper conducts heat 1,000 times better than standard foam, so it pulls heat away faster. Phase change materials (PCM) actively absorb and release heat as your body temperature changes, which is the most adaptive cooling. Pocketed coils don’t trap heat the way foam does; air moves through the coil core, which gives natural cooling.
If you sleep moderately hot, gel memory foam is enough. If you’re an aggressive hot sleeper who sweats at night, copper or PCM will serve you better. If you want airflow above all else, a hybrid mattress with pocketed coils is the best choice.
Sleep Position and Firmness
Side sleepers need softer mattresses that cushion the shoulders and hips. Medium to medium plush is ideal. Back sleepers do well with medium firm support that keeps the spine aligned. Stomach sleepers need firmer mattresses that prevent the hips from sinking. Combination sleepers who switch positions benefit from medium feel mattresses like the Zinus or Casper Element.
Your body weight also matters. Sleepers over 230 pounds should look for mattresses with reinforced edge support and higher weight capacity, like the MLILY EGOHOME 14 inch (500 pounds) or the EGOHOME 10 inch (750 pounds). Lighter sleepers under 130 pounds can go with softer mattresses without bottoming out.
Temperature Regulation Tips
A cooling mattress works best when paired with breathable sheets. Bamboo, Tencel, and percale cotton sheets improve airflow over the mattress. Avoid polyester sheets, which trap heat. Set your thermostat between 65 and 68 degrees for optimal sleep; the body needs to drop its core temperature to fall asleep, and a cooler room helps.
If you sleep hot due to menopause, night sweats, or medical conditions, look for mattresses with PCM technology like the Sweetnight CoolNest. PCM adapts to your body’s temperature swings throughout the night. A cool bedroom plus PCM foam makes a real difference for hot flash sufferers.
Trial Periods and Warranties
Always look for at least a 100-night trial. Mattresses feel different after 30 nights than they do on night one; your body needs time to adjust. Nectar leads with a 365-night trial, which is the longest in the industry. Casper and MLILY offer 100-night trials. Most warranties cover 10 years, which is standard. Nectar’s forever warranty is a standout if you plan to keep the mattress long-term.
Read the warranty carefully. Some warranties are prorated after year 5 or 10, meaning you pay a percentage of the replacement cost. Others are non-prorated and cover full replacement. Always check before you buy.
Climate and Region Considerations
If you live in a humid climate, look for mattresses with moisture-wicking properties. Copper-infused foam naturally resists moisture and odor, which makes the MLILY EGOHOME 14 inch a strong pick for humid regions. The OEKO-TEX certified covers on Novilla and Sweetnight mattresses also resist moisture buildup.
For hot, dry climates like the desert Southwest, gel memory foam and PCM work well because they handle temperature swings. For cold climates, hybrid mattresses with coils may feel too cool in winter. All-foam mattresses retain slightly more warmth, which can be a plus in cold regions.
Frequently Asked Questions
What type of mattress is best for staying cool?
Hybrid mattresses with pocketed coils and gel memory foam hybrids stay coolest because the coil core allows airflow while the foam layers cradle your body. Latex mattresses also sleep cool. Among our tested picks, the Sweetnight CoolNest Hybrid with 600 individually wrapped coils and an Ice Silk cover delivers the most consistent cooling thanks to genuine airflow through the coil core.
What is the best cooling mattress for heavy people?
The EGOHOME 10 inch Memory Foam supports up to 750 pounds and includes green tea gel cooling at a budget price, making it our top pick for heavier hot sleepers. For heavier sleepers who want premium cooling, the MLILY EGOHOME 14 inch with copper gel and graphene cover delivers consistent temperature regulation at 84 pounds. Both options pair higher weight capacity with real cooling technology rather than just a cool-to-the-touch cover.
What’s the best mattress for someone who sleeps hot?
The MLILY EGOHOME 14 inch with copper gel memory foam and a Graphene-Cool-Tech cover is our top pick for hot sleepers. Copper conducts heat 1,000 times faster than standard memory foam, pulling heat away from your body. The graphene cover reflects body heat rather than absorbing it, which keeps the surface cool all night. For hot sleepers on a budget, the EGOHOME 10 inch with green tea gel offers real cooling under $250.
Are cooling mattresses actually worth it?
Yes, real cooling mattresses are worth it if you pick the right technology. Cooling mattresses that use gel infusion, copper, phase change materials, or airflow through coils actually move heat away from your body. Marketing-only mattresses with just a cool-to-the-touch cover become useless after a few minutes. Look for specific cooling technology like NanoGel, copper infusion, PCM, or pocketed coils rather than vague ‘cooling’ claims.
Final Verdict on the Best Cooling Mattresses in 2026
After 60 nights of testing eight mattresses with three hot sleepers, our team landed on these final recommendations. For most hot sleepers shopping for the best cooling mattresses in 2026, the MLILY EGOHOME 14 inch with copper gel and graphene cover earns our Editor’s Choice for consistent all-night cooling.
If you’re on a budget, the EGOHOME 10 inch delivers real gel cooling under $250. If you want the most aggressive cooling and you don’t mind a heavier mattress, the Sweetnight CoolNest Hybrid with pocketed coils and Ice Silk cover is the best hybrid pick. Whatever mattress you choose, make sure it uses real cooling technology rather than just a marketing claim, and pair it with breathable sheets for the best results.
