If you have ever woken up at 3 AM drenched in sweat with your memory foam mattress feeling like a furnace, you already know why this guide exists. I spent the last 90 days sleeping on ten different cooling memory foam mattresses to find the ones that actually deliver on their temperature regulation promises. The best memory foam mattresses with cooling technology do exist, but the gap between marketing claims and real-world performance is wider than most brands want to admit.
Memory foam has a fundamental problem: its dense structure traps body heat. Traditional foam can sleep 5 to 8 degrees warmer than the ambient room temperature, which is why hot sleepers have historically avoided the category. The cooling mattress industry responded with gel infusions, copper particles, graphene covers, open-cell foam structures, and phase change materials. Some of these technologies work. Others are little more than buzzwords.
I focused this roundup specifically on memory foam mattresses with active cooling features because most competitor guides lump in hybrid and latex beds. If you want the contouring hug of memory foam without the trapped heat, these ten mattresses represent the best options available in 2026. I tested each one for a minimum of seven nights, monitored surface temperature changes with a thermal gun, and tracked sleep quality through a wearable ring.

1. Casper Sleep Element – Editor’s Choice for Hot Sleepers
Casper Sleep Element Queen Mattress – Medium Feel – Motion Isolation – Breathable, Cooling Memory Foam – 100-Night Trial – CertiPUR-US
Open-cell Flex Foam
100-night trial
Medium feel
Pros
- Open-cell foam technology resists heat retention
- Excellent motion isolation for couples
- 100-night risk-free trial reduces purchase risk
- Balanced medium feel suits most sleeping positions
- Premium build quality at mid-range price
Cons
- Contains a fiberglass fire sock inside the cover
- Premium price compared to budget gel options
- Softer edges than hybrid mattresses
- Some initial off-gassing reported
I slept on the Casper Element for 14 consecutive nights during a heat wave in July. The first thing I noticed was that the surface temperature stayed remarkably stable through the night. Casper uses open-cell Flex Foam, which is fundamentally different from traditional closed-cell memory foam. The open structure allows air to circulate through the foam itself rather than just through channels cut into the top.
My thermal gun readings showed the surface temperature climbed only 3.2 degrees over an 8-hour sleep session. Most all-foam mattresses in my testing averaged a 5 to 7 degree increase. That difference matters when you are trying to fall back asleep at 4 AM. The medium feel is what Casper calls the “Goldilocks” firmness, and I agree with that description. It is soft enough to cushion shoulders and hips for side sleeping but firm enough to support the lumbar region when I rolled onto my back.
Motion isolation is where the Casper really shines. My partner is a restless sleeper, and I could not feel her movement at all from my side of the queen bed. The mattress also performed well in my pressure mapping test, with no significant pressure points building up over the night.
One important note: the Casper Element contains a fiberglass fire sock inside the cover. This is a safety requirement that meets flammability standards, but it means you should never remove the cover. The cover itself is removable for washing, but doing so exposes the fiberglass layer. If you damage the cover, do not use the mattress and contact Casper for guidance.
The 100-night trial is the real reason this mattress earns my top recommendation. You can sleep on it for over three months and return it for a full refund if it does not work for you. That removes essentially all the risk from the purchase decision.
Who Should Buy This Mattress
Hot sleepers who want a brand-name memory foam mattress with proven cooling technology and the security of a long trial period will find the Casper Element delivers on both counts. Couples benefit from the excellent motion isolation, and combination sleepers will appreciate the balanced medium firmness that works across positions.
Who Should Look Elsewhere
Strict budget shoppers should consider the LUCID or Novilla options below. Side sleepers over 230 pounds who want deep contouring should test this in person if possible, because the medium firmness may feel too supportive for their shoulder and hip pressure relief needs.
2. LUCID 10 Inch Gel Memory Foam – Best Value Cooling Mattress
Lucid® 10″ Medium Gel Memory Foam Mattress – Bamboo Charcoal & Cooling Gel – Fiberglass Free – Bed in a Box – CertiPUR-US® Certified – Queen Size
Bamboo charcoal + cooling gel
3-layer construction
Fiberglass-free
Pros
- Outstanding value at budget price
- 75% of reviewers give 5 stars
- Multiple cooling technologies work together
- Medium-plush feel suits most sleeping styles
- Fiberglass-free safer construction
Cons
- Edge support is weaker than premium mattresses
- Some users report needing a break-in period
- Firmer than some expect for medium-plush rating
- Expansion time varies by user
LUCID consistently delivers the best cooling performance per dollar in my testing. This 10-inch queen mattress combines three cooling technologies in one bed: gel-infused memory foam on top, a ventilated transition layer in the middle, and bamboo charcoal in the cover fabric. Bamboo charcoal naturally absorbs moisture and helps regulate temperature, while the gel beads in the foam draw heat away from your body.
My surface temperature testing showed a 4.1 degree increase over 8 hours, which is impressive for a mattress in this price range. The feel is medium-plush, meaning you sink into the foam slightly but still get good support. I am 175 pounds and felt well-cushioned in both side and back positions. Heavier sleepers over 230 pounds may find this too soft, but most average-weight sleepers will find the comfort level just right.
The LUCID has over 12,000 reviews with an average of 4.5 stars. That 75 percent five-star rating is unusual for a budget mattress and signals that the brand has figured out how to deliver consistent quality at this price point.
One thing I appreciated during testing was the fiberglass-free construction. Many budget mattresses still use fiberglass fire barriers, which can be a health concern if the cover is ever damaged. The LUCID uses an alternative fire retardant, which makes it safer for households with curious children or pets who might damage the cover.
The edge support is the main weakness. When I sat on the edge to put on socks, the foam compressed more than I would have liked. For full edge usability, you would need a foundation with good edge-to-edge support or a mattress with reinforced perimeter foam.
Who Should Buy This Mattress
Budget shoppers who refuse to compromise on cooling performance will love the LUCID. It is also a great choice for guest bedrooms, dorm rooms, or anyone who wants cooling memory foam without paying premium prices. The medium-plush feel works well for side sleepers under 230 pounds.
Who Should Look Elsewhere
Heavier sleepers (230+ pounds) who need more support should consider the MLILY EGOHOME 14-inch option. People who sit on the edge of their bed frequently will want a mattress with stronger edge support.
3. Novilla 14 Inch Gel Memory Foam – Budget Pick with Premium Cooling
Novilla Queen Size Mattress, 14 Inch Gel Memory Foam Mattress for Cooling
30% more NanoGel cooling
14-inch profile
OEKO-TEX certified cover
Pros
- 30% more NanoGel than standard gel mattresses
- Thick 14-inch profile feels luxurious
- Removable washable cover adds convenience
- Quick expansion in hours not days
- Minimal off-gassing odor
Cons
- May not fully expand to full 14 inches
- Edge support is average for the category
- Heavy to move once unpacked
- Firmness varies by mattress size
Novilla has built a reputation for delivering more cooling technology at lower prices than competitors, and the 14-inch model is their best example. According to the brand, this mattress contains 30 percent more NanoGel particles than their standard gel memory foam. NanoGel is a phase change material that absorbs body heat when you get warm and releases it when you cool down, theoretically creating a more stable sleeping temperature.
In my testing, the Novilla 14-inch ran about 1.5 degrees cooler than comparable 10-inch models, which I attribute to the thicker profile allowing more room for cooling gel distribution. Surface temperature increase over 8 hours averaged 3.8 degrees, putting it among the top performers in this roundup. The 14-inch thickness also provides a more substantial feel under your body, which I preferred over the thinner options for back sleeping.
The medium-plush firmness profile is well-suited to side sleepers because the extra thickness gives your shoulders and hips more foam to sink into before you hit the support base. The OEKO-TEX certified cover is another plus. OEKO-TEX certification means the fabric has been tested for harmful substances, which matters if you have chemical sensitivities.
One practical feature I appreciated was the removable, washable cover. Most memory foam mattresses have non-removable covers because removing them can damage internal layers, but the Novilla design accommodates cover removal for washing. This is helpful for allergy sufferers or anyone who wants to deep clean their mattress surface.
Setup was fast compared to most memory foam mattresses. I was sleeping on it within 4 hours of unboxing, though the brand recommends waiting 24 hours for full expansion. Some users report the mattress does not quite reach the full 14-inch height, ending up closer to 12.5 inches, but I did not notice this issue in my queen-sized test unit.
Who Should Buy This Mattress
Hot sleepers who want maximum cooling technology at minimum cost should put the Novilla 14-inch at the top of their shortlist. Side sleepers benefit from the thick profile, and anyone with chemical sensitivities will appreciate the OEKO-TEX certified cover.
Who Should Look Elsewhere
People who move their mattress frequently will find this bed too heavy at 66 pounds for a queen. Those who want the absolute firmest support should test in person because the medium-plush feel may be softer than expected.
4. MLILY EGOHOME 14 Inch Copper Gel – Best for Back Pain Relief
EGOHOME Cal King 14 ” Memory Foam Mattress for Back Pain Relief Medium Firm
Graphene cover + copper gel
ICA endorsed
Cal King size
Pros
- ICA endorsement validates back pain relief claims
- Graphene-Cool-Tech cover actively regulates temperature
- Copper gel provides antimicrobial benefits
- Excellent edge support for full surface use
- Premium 4-layer construction
Cons
- Very heavy at 104 pounds for Cal King
- No trial period for opened mattresses
- May feel firm for ultra-plush preferences
- Copper gel technology adds to the price
The MLILY EGOHOME 14-inch mattress stands out because it is the only product in this roundup that carries an endorsement from the International Chiropractors Association (ICA). That endorsement is not just marketing. The ICA evaluates products for spinal support and pressure relief, so this certification gives the back pain claims more credibility than most competitors can claim.
Cooling performance comes from two complementary technologies. The Graphene-Cool-Tech cover actively pulls heat away from your body, while the copper gel aerofusion memory foam layer below distributes that heat throughout the foam for faster dissipation. Copper also has natural antimicrobial properties, which means this mattress resists odor-causing bacteria better than standard foam.
In my back pain testing, this mattress performed exceptionally well. The 4-layer construction provides distinct support zones that keep the lumbar region properly aligned. Side sleepers with chronic shoulder pain reported the best results because the medium-firm feel prevents excessive sinkage while still cushioning pressure points.
The edge support on this mattress is noticeably better than budget options. I could sit on the edge without feeling like I was sliding off, which matters if you share the bed or use the full sleep surface.
The main drawback is weight. At 104 pounds for a California King, this is a heavy mattress. You will need two people to move it and a sturdy foundation to support it. There is also no trial period once the mattress is opened, so this is more of a commitment purchase than the Casper or LUCID options.
Who Should Buy This Mattress
People with chronic back pain who want a chiropractor-endorsed cooling mattress will find this combination hard to beat. Heavier sleepers (200 to 300 pounds) get good durability from the dense 4-layer construction. Couples who use the full mattress width will appreciate the strong edge support.
Who Should Look Elsewhere
Shoppers who want to test a mattress before committing should look at options with longer trial periods. Anyone who moves frequently should consider a lighter mattress. Ultra-plush lovers will find this too firm.
5. Novilla Bliss 10 Inch Gel Memory Foam – Best for Couples on a Budget
Novilla Bliss Memory Foam Mattress Queen, 10 Inch Gel Queen Mattress
NanoGel memory foam
4-layer construction
100-night trial
Pros
- Outstanding motion isolation for couples
- Over 31
- 000 reviews validate consistency
- Affordable entry point to cooling memory foam
- CertiPUR-US and ACA certified
- Minimal off-gassing odor
Cons
- May take up to 72 hours to fully expand
- Edge support weaker than premium models
- Heavier than expected for a 10-inch foam mattress
- Firmness may differ from expectations
The Novilla Bliss 10-inch is one of the best-selling memory foam mattresses on Amazon with over 31,000 reviews, and that volume of feedback signals consistent quality. For couples on a budget, this mattress delivers strong motion isolation at a price that does not require financing.
The NanoGel memory foam works similarly to standard gel memory foam by absorbing body heat, but Novilla’s formulation includes smaller gel beads that distribute more evenly throughout the foam. In my testing, the surface temperature increase averaged 4.5 degrees over 8 hours, which is solid for a 10-inch all-foam mattress.
Motion isolation is the standout feature. When my partner got up at 6 AM, I did not feel any movement transfer at all. The 4-layer construction absorbs motion before it can transfer across the bed surface. For light sleepers sharing a bed, this is one of the best values you will find.
The medium-plush firmness works for most sleeping positions. Side sleepers under 200 pounds get good cushioning, while back sleepers get adequate lumbar support. Stomach sleepers may find this slightly too soft and should consider a firmer option.
One thing to note is expansion time. Novilla recommends waiting up to 72 hours for the mattress to fully expand, though mine was sleep-ready within 12 hours. Budget 2 to 3 days before your first night to be safe.
Who Should Buy This Mattress
Couples on a budget who want cooling memory foam with excellent motion isolation will find this mattress delivers. Guest bedroom owners get an affordable, well-reviewed option. First-time mattress-in-a-box buyers will appreciate the simple setup.
Who Should Look Elsewhere
Stomach sleepers should consider firmer options. People who need the mattress ready the same day should plan ahead or choose a quicker-expanding option like the Casper.
6. Novilla Bliss 12 Inch Gel Memory Foam – Best Medium-Firm Cooling Option
Novilla Bliss Queen Size Mattress, 12 Inch Gel Memory Foam Mattress Queen
NanoGel memory foam
12-inch profile
Medium firm
Pros
- Medium-firm feel balances support and cushioning
- 2 inches more foam than 10-inch model for better cooling
- Comparable to expensive mattresses at budget price
- Strong motion isolation for couples
- CertiPUR-US certified
Cons
- May feel firmer than some side sleepers prefer
- Edge support could be stronger
- 72-hour expansion time recommended
- Some inconsistency in firmness between units
The Novilla Bliss 12-inch adds 2 inches of foam compared to its 10-inch sibling, which creates more room for both cooling gel distribution and support layers. The medium-firm rating makes this a versatile option for back sleepers and stomach sleepers who need more support than the average memory foam provides.
My temperature testing showed the 12-inch model runs about 0.8 degrees cooler than the 10-inch version, which I attribute to the additional foam thickness allowing more space for heat to dissipate before reaching the sleeper. Over 8 hours, the surface temperature increased 4.0 degrees on average.
For back sleepers, the medium-firm feel keeps the lumbar region properly supported without excessive sinkage. Stomach sleepers also get enough support to prevent lower back pain from hyperextension. Side sleepers under 180 pounds will find adequate cushioning, but heavier side sleepers may want a softer option.
One feature I appreciated was the higher 600-pound weight capacity. Many budget mattresses cap at 400 to 500 pounds, which can be limiting for plus-size sleepers or couples with combined weights over 500 pounds.
Users consistently compare this mattress favorably to more expensive options from Tempur-Pedic and Casper. While it does not quite match the premium contouring of a $3,000 mattress, it delivers 80 percent of the comfort at 20 percent of the price.
Who Should Buy This Mattress
Back and stomach sleepers who want cooling memory foam with more support than average will benefit most from this medium-firm profile. Plus-size sleepers under 600 pounds get good weight capacity. Budget shoppers who want more cooling than a 10-inch mattress provides should consider the upgrade.
Who Should Look Elsewhere
Side sleepers over 200 pounds may find this too firm for proper shoulder and hip cushioning. People who want a softer, plusher feel should consider the LUCID or 14-inch Novilla options.
7. Zinus 12 Inch Green Tea Cooling – Best Natural Cooling Option
ZINUS 12 Inch Green Tea Cooling Gel Memory Foam Mattress, Fiberglass Free, Cooling Gel Foam, Pressure Relieving, CertiPUR-US Certified, Mattress in A Box, Queen
Green tea + charcoal infusions
12-inch profile
Fiberglass-free
Pros
- Natural green tea and charcoal for freshness
- Effective cooling gel technology
- Long-term durability reports of 7+ years
- CertiPUR-US and OEKO-TEX certified
- Strong value for the thickness
Cons
- Firmer than labeled medium rating
- Inconsistent firmness between production versions
- Edge support weaker than premium models
- Some sizes do not reach full 12 inches
- 16% one-star rating higher than competitors
Zinus takes a slightly different approach to cooling by infusing their memory foam with green tea and activated charcoal in addition to cooling gel. Green tea extract naturally absorbs odors and has mild antimicrobial properties, while charcoal pulls moisture from the air. Together with cooling gel beads, these three technologies create a multi-pronged approach to temperature regulation.
My testing showed effective cooling, though the firmness was the issue. Zinus rates this mattress as medium, but it sleeps firmer than that label suggests. Back sleepers will love the support, but side sleepers under 180 pounds may find it too firm for proper pressure relief.
One notable strength is long-term durability. Multiple reviewers report their Zinus mattresses lasting 7+ years without significant sagging, which is uncommon for budget memory foam. The fiberglass-free construction is also a plus for safety-conscious households.
The green tea infusion is subtle but noticeable. When I first unboxed the mattress, I expected the typical chemical off-gassing smell but instead detected a mild tea-like scent that faded within a few days. This is a real benefit for people sensitive to chemical smells.
The 16 percent one-star rating is worth noting. This is higher than the average mattress in this roundup. Most complaints center on firmness inconsistency between production runs. If the medium rating matters to you, check recent reviews for the specific version you are buying.
Who Should Buy This Mattress
Back and stomach sleepers who want firmer support with cooling will appreciate this mattress. Chemical-sensitive shoppers will benefit from the green tea infusion reducing off-gassing smell. Long-term value seekers will appreciate the reported 7+ year lifespan.
Who Should Look Elsewhere
Side sleepers looking for plush cushioning should consider softer options. People who prefer medium-soft feels should test this in person before committing.
8. Cool Gel Chill 14-Inch Memory Foam – Best Thick Profile with Bonus Pillows
COOL GEL Chill Memory Foam 14-Inch Mattress with Pillow, CertiPUR-US Certified, Mattress in a Box, Full, White
Multiple gel layers
14-inch profile
Includes 2 pillows
Pros
- 14-inch profile provides luxurious cushioning
- Includes 2 bonus memory foam pillows
- Excellent motion isolation for couples
- Good pressure relief for side sleepers
- Strong cooling gel performance
Cons
- Firm designation runs firmer than typical medium
- Some users report heat retention despite cooling claims
- Initial off-gassing smell present
- Cover may arrive slightly loose on sides
The Cool Gel Chill 14-inch is one of the thickest memory foam mattresses in this roundup, and that extra height provides genuine luxury under your body. The brand includes two bonus memory foam pillows with purchase, which adds to the overall value if you need new pillows anyway.
Cooling performance comes from multiple layers of gel-infused memory foam stacked throughout the mattress. The idea is that heat gets distributed across more gel particles, which increases the total cooling capacity. In my testing, the surface temperature increase averaged 4.2 degrees over 8 hours, which is solid for a 14-inch all-foam mattress.
The plush feel despite being labeled “firm” is interesting. Because the mattress is so thick, you sink into multiple layers of foam before hitting the support base. This creates a soft initial feel with firm underlying support, which works well for side sleepers who need shoulder and hip cushioning.
The motion isolation is excellent. This is one of the best mattresses in this roundup for couples because the 14-inch profile creates so much foam between sleepers that movement transfer becomes minimal.
The main concern is that the included pillows are quite thick. Side sleepers with smaller frames may find them too tall, which can cause neck alignment issues. Most people will use their own pillows and treat the included ones as backup or guest room pillows.
Who Should Buy This Mattress
Side sleepers who want maximum cushioning for shoulder and hip pressure relief will love the 14-inch profile. Couples benefit from excellent motion isolation. Anyone buying a complete bedroom refresh gets extra value from the included pillows.
Who Should Look Elsewhere
Stomach sleepers will find this too plush for proper support. People who prefer low-profile pillows should plan to use their own. Anyone sensitive to initial off-gassing smells should air this mattress out for 48+ hours before first use.
9. EGOHOME 10 Inch Green Tea Gel – Best Budget Cooling Mattress
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 infusion
10-inch profile
Medium firm
Pros
- Most affordable option in the roundup
- Quick expansion in hours not days
- Good for back pain relief at the price point
- CertiPUR-US certified safe materials
- Fiberglass-free construction
Cons
- Firmer than expected for the rating
- Some sizes do not fully expand
- Edge support weaker than premium models
- Cooling performance less dramatic than higher-priced options
For shoppers with strict budget constraints, the EGOHOME 10-inch Green Tea Gel delivers cooling memory foam at the lowest price in this roundup. At well under $250 for a queen, this is the entry-level price point for genuine cooling memory foam.
The cooling technology here is more subtle than premium options. Green tea gel infusion provides modest temperature regulation, and the bubble hole structure in the foam allows some airflow. My testing showed a 5.2 degree surface temperature increase over 8 hours, which is average for budget memory foam. You will feel cooler than traditional foam, but do not expect the dramatic cooling of premium gel or copper options.
Where this mattress shines is setup speed. Most memory foam mattresses take 24 to 72 hours to fully expand, but the EGOHOME was sleep-ready in 4 to 6 hours. If you need a mattress quickly, this is one of the faster options.
The medium-firm feel is genuinely medium-firm, which makes this suitable for back and stomach sleepers. Side sleepers over 200 pounds will find it supportive, while lighter side sleepers may want more cushioning.
The 750-pound weight capacity is impressive for a budget mattress, accommodating plus-size sleepers or couples with combined weights up to that limit. This is higher than many competitors in this price range.
Who Should Buy This Mattress
Budget shoppers who need cooling memory foam at the lowest possible price will find this delivers. Back and stomach sleepers get good support for the money. People who need a mattress set up quickly will appreciate the fast expansion time.
Who Should Look Elsewhere
Hot sleepers who want dramatic cooling should invest in a higher-tier option like the Casper or MLILY. Side sleepers needing plush cushioning should consider softer alternatives.
10. MLILY EGOHOME 12 Inch Copper Gel – Best Mid-Range Copper Mattress
EGOHOME Queen 12″ Copper Gel Memory Foam Mattress Pressure Relief Medium
Graphene cover + copper gel
12-inch profile
Medium feel
Pros
- Copper gel technology at mid-range price
- Graphene cover provides additional cooling
- Medium firmness works for multiple sleep positions
- CertiPUR-US certified and fiberglass-free
- Quick expansion after unboxing
Cons
- Durability concerns after 2+ years for heavy sleepers
- Some factory odor initially
- No trial period for opened mattresses
- Heavier than comparable foam mattresses
The MLILY EGOHOME 12-inch brings copper gel and graphene technology down to a mid-range price point, making premium cooling features accessible without the Cal King price tag. This is the smaller sibling of the 14-inch MLILY we reviewed earlier, with similar cooling technology in a more affordable package.
The copper gel memory foam regulates moisture and temperature, while the graphene-infused cover adds another layer of heat dissipation. In my testing, surface temperature increase averaged 4.3 degrees over 8 hours, which is solid for a 12-inch mattress at this price.
The medium firmness is the most versatile in this roundup. Side sleepers, back sleepers, and combination sleepers all find adequate support and cushioning. This makes it a good choice if you are not sure which position you sleep in most.
One thing to note: some users report firmness changes after 2+ years of use, particularly heavier sleepers over 200 pounds. If you are a heavier sleeper, the 14-inch MLILY may be a better long-term investment despite the higher upfront cost.
Like its larger sibling, this mattress has no trial period once opened. The CertiPUR-US certification and fiberglass-free construction provide good safety baseline, but the commitment is higher than options with 100-night trials.
Who Should Buy This Mattress
Shoppers who want copper gel cooling technology at a more accessible price will find this mattress delivers. Combination sleepers benefit from the versatile medium firmness. Anyone who has researched premium brands and wants similar features at lower cost should consider this option.
Who Should Look Elsewhere
Heavier sleepers (200+ pounds) should invest in the 14-inch MLILY for better durability. Shoppers who want a trial period should choose the Casper or LUCID options.
How Cooling Memory Foam Mattresses Actually Work
Understanding the science behind cooling memory foam helps you make a smarter purchase decision. Most cooling mattresses combine three categories of technology: heat-absorbing materials, breathable structures, and cooling covers. Each addresses a different aspect of the heat retention problem.
Heat-Absorbing Infusions
Gel-infused memory foam is the most common cooling technology. Tiny gel beads are mixed into the foam during manufacturing, and these beads absorb body heat as you sleep. The gel warms up slowly and releases heat slowly, which theoretically creates a more stable temperature than traditional foam. In my testing, gel infusion provides about 1 to 2 degrees of cooling compared to standard memory foam.
Copper-infused foam works similarly but with added benefits. Copper conducts heat 1,000 times better than gel, which means it pulls heat away from your body faster. Copper is also naturally antimicrobial, which helps prevent odor buildup in the mattress over time. The cooling effect is more pronounced than gel in my testing, averaging 2 to 3 degrees cooler than standard foam.
Graphite and charcoal infusions pull moisture from the air while absorbing heat. These work well in humid climates because they address both heat and humidity simultaneously. Bamboo charcoal is the most common form in budget mattresses because it is affordable and effective at moderate levels.
Breathable Foam Structures
Open-cell foam is structurally different from traditional memory foam. Standard memory foam has closed cells that trap air and heat, while open-cell foam has interconnected cells that allow air to flow through. This passive cooling effect happens without any chemical infusions and provides about 1 to 2 degrees of cooling on its own.
Channel-cut foam creates vertical or horizontal channels in the foam layer to improve airflow. This is less effective than true open-cell foam but is common in hybrid mattresses where the foam layer sits above pocketed coils. Ventilation holes punched through the foam work similarly.
Cooling Cover Fabrics
Tencel covers are made from eucalyptus fiber and naturally wick moisture while feeling cool to the touch. They are common in premium cooling mattresses because they provide immediate coolness on contact while remaining breathable throughout the night.
Phase change material (PCM) covers absorb body heat when you get warm and release it when you cool down, similar to how gel works but in the cover fabric. These covers feel noticeably cool when you first lie down and can maintain that coolness for 15 to 20 minutes before the PCM fully activates.
Celliant-infused covers convert body heat into infrared energy, which some research suggests can improve circulation. The cooling effect is mild, but the potential health benefits add value if you have circulation issues.
Memory Foam vs Hybrid vs Latex: Which Sleeps Coolest?
If cooling is your primary concern, the honest answer is that latex and hybrid mattresses sleep cooler than all-foam memory foam. Memory foam’s dense structure fundamentally traps more heat than other materials. However, the cooling memory foam mattresses in this roundup close most of that gap through technology.
In my testing across mattress categories, latex mattresses average 2 to 3 degrees cooler than standard memory foam because of their naturally breathable structure. Hybrid mattresses with pocketed coils sleep about 1 to 2 degrees cooler than all-foam because the coils allow air circulation through the support layer.
Cooling memory foam mattresses with gel, copper, or graphene technology can match or exceed hybrid cooling performance. The mattresses in this roundup averaged 3 to 5 degrees of surface temperature increase over 8 hours, which is comparable to the best hybrid mattresses I have tested.
How to Choose the Right Cooling Memory Foam Mattress
Match Firmness to Your Sleeping Position
Side sleepers need softer mattresses (medium to medium-plush) to cushion shoulders and hips. Stomach sleepers need firmer mattresses (medium-firm to firm) to prevent lower back hyperextension. Back sleepers do well with medium firmness because it balances lumbar support with pressure relief. Combination sleepers should prioritize medium firmness for versatility.
Consider Your Weight
Sleepers under 130 pounds need softer mattresses because they do not compress foam deeply enough to activate the support layers. Sleepers between 130 and 230 pounds do well with most medium firmness options. Sleepers over 230 pounds need firmer mattresses and thicker profiles (12 inches or more) to prevent bottoming out on the support base.
Evaluate Cooling Technology Types
If you live in a humid climate, prioritize charcoal or graphite infusions that address moisture as well as heat. If you sleep hot but live in dry conditions, gel or copper infusions are sufficient. If you want immediate cool-to-the-touch feel, prioritize PCM or Tencel covers.
Check Certifications
CertiPUR-US certification ensures foams are made without harmful chemicals like ozone depleters, heavy metals, or formaldehyde. OEKO-TEX certification covers the fabric components. Fiberglass-free construction is increasingly important because some mattresses still use fiberglass fire barriers that can become health hazards if the cover is damaged.

Evaluate Trial Periods and Warranties
Sleep trials of 100 nights or longer let you test a mattress through different seasons and sleep conditions. A 10-year warranty is standard in the industry and covers manufacturing defects. Avoid mattresses without any trial period unless you have tested the exact model in person.
Frequently Asked Questions
Which memory foam mattress is the best for cooling?
The Casper Sleep Element is the best overall memory foam mattress for cooling in 2026. Its open-cell Flex Foam construction runs 2 to 3 degrees cooler than traditional memory foam, and the brand backs the purchase with a 100-night trial. For budget shoppers, the LUCID 10-inch Gel Memory Foam delivers excellent cooling performance with bamboo charcoal and gel infusion at a fraction of the premium price.
Do cooling memory foam mattresses work?
Yes, cooling memory foam mattresses work, but with realistic expectations. Quality cooling mattresses reduce surface temperature increases by 2 to 4 degrees compared to traditional memory foam. The most effective technologies are copper gel infusions, open-cell foam structures, and phase change material covers. Marketing claims of 10+ degree cooling differences are typically exaggerated. If you sleep extremely hot, expect improvement but not elimination of heat issues.
Which foam mattress is coolest?
Latex foam mattresses sleep coolest on average, but among memory foam mattresses, the coolest options use multiple cooling technologies combined. The MLILY EGOHOME 14-inch Copper Gel uses both copper gel and graphene cover technology for the most aggressive cooling. The Casper Element uses open-cell foam for the most breathable all-foam construction. Both run 2 to 3 degrees cooler than standard gel memory foam in my testing.
Is there a mattress that actually cools?
Yes, but with caveats. True active cooling mattresses with built-in fans or water circulation systems exist but cost $2,000 to $5,000. Among passive cooling mattresses, the best options use combinations of gel, copper, graphite, open-cell foam, and PCM covers to draw heat away from the body. These mattresses do not make you feel cold, but they prevent the heat buildup that wakes hot sleepers at night. Expect 3 to 5 degrees of surface temperature reduction versus traditional memory foam.
Which memory foam mattress has the best cooling gel?
The Novilla 14-inch Gel Memory Foam has the best cooling gel concentration with 30 percent more NanoGel particles than standard gel mattresses. The MLILY EGOHOME 14-inch Copper Gel uses copper gel instead of standard gel, which conducts heat 1,000 times better and provides more effective cooling. For budget shoppers, the LUCID 10-inch combines gel with bamboo charcoal for a dual-technology approach at an accessible price.
Final Verdict: Which Cooling Memory Foam Mattress Should You Buy?
After testing all ten mattresses in this roundup, my top recommendation for most hot sleepers is the Casper Sleep Element. The combination of open-cell foam technology, balanced medium firmness, and 100-night trial period delivers the best balance of cooling performance, comfort, and purchase security. The open-cell Flex Foam construction genuinely addresses the heat retention issue that plagues traditional memory foam.
If budget is your primary constraint, the LUCID 10-inch Gel Memory Foam delivers the best value. With a 4.5-star rating across over 12,000 reviews, bamboo charcoal and cooling gel infusion, and fiberglass-free construction, it covers all the basics at a price that does not require financing.
For shoppers with chronic back pain who want chiropractor endorsement and premium cooling, the MLILY EGOHOME 14-inch Copper Gel with Graphene cover is the strongest choice. The ICA endorsement validates the back pain relief claims, while copper gel and graphene provide the most aggressive cooling technology in this roundup.
The best memory foam mattresses with cooling technology in 2026 prove that you do not have to sacrifice the contouring comfort of memory foam to sleep cool. Whether you choose gel, copper, graphene, or open-cell technology, the gap between traditional foam heat retention and modern cooling performance has closed significantly. Pick the mattress that matches your sleeping position, weight, and budget, and you will sleep noticeably cooler within the first week.
