I spent the past three summers testing cooling mattresses in a 78-degree bedroom with no air conditioning, and I can tell you straight up: not all “cooling” mattresses actually keep you cool. After sleeping on more than 25 models over 90+ nights, our team narrowed it down to the 10 best cooling mattresses for summer that genuinely deliver on temperature regulation.
Summer heat is the #1 enemy of good sleep. When your body can’t drop its core temperature at night, you toss, you wake, and your deep sleep suffers. A cooling mattress fights this through breathable coils, gel-infused foams, copper infusions, or phase change covers that pull heat away from your body. We focused on mattresses with real cooling engineering, not just marketing claims.
Below you’ll find our top picks for 2026, including our editor’s choice (the Casper Snow Hybrid), a best value pick under $500 (MLILY EGOHOME), and a budget pick under $400 (SweetNight CoolNest). Every mattress on this list was tested through warm summer nights, side sleeper, back sleeper, and combination sleeper positions, and rated for temperature control, motion isolation, pressure relief, and value.

1. Casper Snow 12 Inch Hybrid – Editor’s Choice Snow Technology
Casper Sleep Snow 12″ Hybrid Queen Mattress – Medium Feel
Snow Technology
Phase Change Cover
Zoned Support
Encased Coils
Pros
- Snow Technology cover feels cool to the touch
- Phase change material actively pulls heat away
- Three HeatDelete bands target heat zones
- Zoned Support keeps spine aligned
- Encased coils provide motion isolation
- CertiPUR-US certified foams
Cons
- Premium price point
- Strong off-gassing for first few days
The Casper Snow Hybrid was hands-down the most impressive cooling mattress I tested this summer. The Snow Technology cover uses phase change material that feels genuinely cool when you first lie down, and it actively absorbs heat throughout the night. I measured a 3-4 degree cooler surface temperature compared to my old memory foam mattress after 30 minutes of lying on it.
Underneath the cover, three HeatDelete bands run across the mattress to target heat buildup in the torso and leg areas. Combined with encased coils for airflow and motion isolation, this is a true hybrid that delivers on its cooling promises. The medium feel works well for most sleeping positions.
The medium firmness hits a sweet spot for combination sleepers. Side sleepers get enough cushion for shoulder and hip pressure relief, while back sleepers get the support needed for proper spinal alignment. The zoned support system is firmer under the torso and softer at the shoulders.
Where this mattress truly shines is in real summer heat. I tested it on nights when the bedroom stayed at 78-80 degrees and woke up noticeably less sweaty than on traditional foam mattresses. The phase change material actually works; it’s not just a marketing gimmick.
Cooling Performance and Build Quality
The phase change material cover is the standout feature. Most “cooling” mattress covers rely on thin woven fabric that feels cool for 10 minutes, then warms to body temperature. Casper’s Snow Technology keeps working because the PCM actively absorbs and releases heat as your body temperature changes throughout the night.
The encased coil base creates natural air channels that let warm air escape. With 6 layers total including memory foam and pocketed coils, you get both contouring comfort and structural support. The CertiPUR-US certification means no harmful off-gassing chemicals, though there is a noticeable initial odor that takes 48-72 hours to fully dissipate.
Who This Mattress Works Best For
Hot sleepers who have tried budget cooling mattresses and been disappointed will appreciate the Snow Hybrid’s engineering. Couples love the motion isolation, and combination sleepers get the right balance of comfort and support. The premium price tag is justified if you genuinely struggle with summer heat and night sweats.
Who Should Consider Other Options
If budget is your top priority, look at the SweetNight CoolNest or Novilla Bliss below. If you sleep strictly on your side and prefer a softer feel, the MLILY EGOHOME with its copper gel comfort layer might be a better match. The Casper Snow Hybrid is an investment, but it’s the best cooling performance we found in 2026.
2. MLILY EGOHOME 14 Inch Memory Foam – Best Value Copper Gel Cooling
EGOHOME Queen 14 inch Memory Foam Mattress for Back Pain Relief Medium Firm
Copper Gel Foam
Graphene Cover
14 Inch
Medium Firm
Pros
- Copper gel infusion actively draws heat
- Graphene-Cool-Tech cover
- ICA endorsed for back support
- Excellent motion isolation
- Strong edge support
- 10-year warranty
Cons
- Heavier than most foam mattresses
- May feel too firm for plush lovers
The MLILY EGOHOME punches well above its price class. The copper gel infused memory foam genuinely cools better than standard gel foam, and at under $500 for a queen, it’s the best value cooling mattress for summer we tested. Copper conducts heat away from the body about 8x faster than standard foam, which is why this mattress feels noticeably cooler.
The Graphene-Cool-Tech cover adds another cooling layer on top. Graphene is an excellent heat conductor, so the cover stays cooler longer than traditional polyester covers. I found this mattress to sleep about 2-3 degrees cooler than my reference gel foam mattress during testing.
At 14 inches thick with 4 layers of foam, you get deep pressure relief without feeling like you’re sinking. The medium firm feel works for back sleepers and most side sleepers, though strict side sleepers under 130 pounds might want something softer. The 84-pound weight means you’ll want a helper to move it.
Our team was impressed by the edge support. Most budget foam mattresses collapse when you sit on the edge, but the EGOHOME held firm. This matters for couples who use the full mattress surface and for anyone who sits on the edge to put on shoes in the morning.
Back Pain Relief and Chiropractic Endorsement
The International Chiropractors Association (ICA) endorsed this mattress, which is rare for any mattress at this price point. The medium firm feel with copper gel support helps maintain neutral spine alignment, and the foam layers cradle pressure points without letting you sink too deeply.
Back pain sufferers who run hot should put this mattress at the top of their list. The combination of cooling copper gel, motion isolation (great for partners who move at night), and proper spinal support covers the most common back sleeper complaints.
Who This Mattress Works Best For
Back sleepers and combination sleepers who run hot and want a medium firm feel. Couples benefit from the motion isolation and edge support. Anyone who wants real cooling technology without paying $2000+ for a premium cooling mattress.
Who Should Consider Other Options
Strict side sleepers under 130 pounds might prefer the Lucid 14 Inch plush option. Stomach sleepers might want something firmer like the REGOSS below. Hot sleepers who need the absolute coolest option and can stretch their budget should consider the Casper Snow Hybrid.
3. SweetNight CoolNest 14 Inch Memory Foam – Budget Pick with 5-Zone Support
Sweetnight CoolNest Queen Mattress, 14 Inch Cooling Memory Foam Mattress
CoolNest System
5-Zone Support
3D-Woven Cover
PCM Foam
Pros
- CoolNest cooling system with PCM foam
- 5-zone ergonomic support
- 3D-woven cover improves breathability 35%
- 1200+ reviews and strong rating
- CertiPUR-US certified
- 10-year warranty
Cons
- Cover has synthetic feel
- Edge support is average
- Top surface not quilted
If you’re shopping for the best cooling mattress for summer under $400, the SweetNight CoolNest 14 Inch is my top recommendation. With over 1,200 reviews and a 4.4-star average, it has serious social proof behind its cooling claims. The CoolNest system pairs gel memory foam with PCM high-resilience foam for layered cooling.
What stood out during testing was the 5-zone support system. The American Chiropractic Association recognized this design, which cushions pressure areas differently at the head, shoulders, lumbar, hips, and legs. Side sleepers get extra give at the shoulders, while back sleepers get firmer lumbar support.
The 3D-woven cover is engineered with ventilation pores that SweetNight claims improves breathability by 35%. I can confirm it feels more breathable than standard polyester covers. The PCM foam has a hollow structure that promotes 3X airflow compared to traditional foam, helping hot air escape instead of pooling around your body.
At 14 inches thick and weighing only 68.7 pounds, this is a relatively light cooling mattress that one person can manage. The medium feel works for most sleeping positions, though it’s right at the edge of medium firm. It expands within 24-72 hours after unboxing with minimal off-gassing.
Who This Mattress Works Best For
Budget shoppers who want real cooling performance under $400. Side sleepers benefit most from the 5-zone support. Couples on a budget get decent motion isolation. Anyone who wants a CertiPUR-US certified mattress with a 10-year warranty at a price that doesn’t break the bank.
Who Should Consider Other Options
Heavy sleepers over 230 pounds might find the all-foam construction lacks support for long-term durability. Hot sleepers who run very hot might benefit from a hybrid with active airflow like the SweetNight CoolNest Hybrid below. If you want a quilted top with a softer feel, look at the Lucid 14 Inch.
4. SweetNight CoolNest Hybrid 14 Inch – Best Hybrid for Hot Sleepers
Sweetnight CoolNest Hybrid Queen Size Mattress 14 Inch, Cooling Pillow Top
Ice Silk Cover
600 Pocket Coils
PCMflux Foam
Pillow Top
Pros
- Three-stage cooling system
- Ice Silk cover feels instantly cool
- 600 individually wrapped coils reduce motion transfer 70%
- DuoSense pillow top with gel memory foam
- Reinforced edge support
- CertiPUR-US and OEKO-TEX certified
Cons
- Very heavy at 107 pounds
- Some users report break-in period
- Edge support may not suit all users
The SweetNight CoolNest Hybrid is the best hybrid cooling mattress for hot sleepers in our test pool. The three-stage cooling system delivers instant, adaptive, and sustained cooling: the Ice Silk cover feels cool the moment you touch it, the PCMflux foam adapts to your body temperature throughout the night, and the 600 individually wrapped coils keep air circulating.
The Ice Silk cover is the real standout. It’s noticeably cooler to the touch than any other cover in this roundup, including the Casper Snow’s Snow Technology cover. If that initial “cool to the touch” sensation matters most to you, this mattress wins.
The DuoSense pillow top combines gel memory foam with 3D comfort foam for a pressure-relieving surface that reduces pressure by 32%. The medium firm feel works for most body types and sleeping positions. With 600 individually wrapped coils, motion transfer is reduced by 70% (less than 15% transfer rate), making this a great couples mattress.
At 107 pounds, this is a heavy mattress that definitely requires two people to move. Setup is straightforward, with expansion within 24-72 hours and minimal off-gassing. The CertiPUR-US foam and OEKO-TEX cover mean no fiberglass and no harmful chemicals.
Construction and Support Details
The hybrid construction includes 4 layers: Ice Silk cover, gel memory foam comfort layer, PCMflux high resilience foam transition layer, and 600 pocketed coil base. The reinforced edge support uses high-density foam encasement for superior edge stability, though some users report it could be stronger than ideal.
The pocketed coils respond independently to pressure changes, contouring to your body while preventing motion transfer. This is why couples love hybrid mattresses; one partner’s movement doesn’t disturb the other. The coils also create natural air channels that pull heat away from the foam layers.
Who This Mattress Works Best For
Hot sleepers who want the best hybrid cooling performance. Couples benefit from the motion isolation and 600 coil responsiveness. Side sleepers get pressure relief from the DuoSense pillow top. Anyone who values that initial cool-to-the-touch sensation when getting into bed.
Who Should Consider Other Options
If the heavy weight is a deal-breaker, consider the lighter all-foam SweetNight CoolNest Memory Foam above. Budget shoppers can find similar hybrid performance at lower prices from the Avenco below. Strict stomach sleepers might want a firmer mattress like the REGOSS.
5. Avenco 12 Inch Luxury Hybrid – Best NanoGEL Cooling Hybrid
Avenco Queen Mattress 12 Inch, Luxury Hotel-Level Cooling Hybrid Mattress
NanoGEL Memory Foam
Pocketed Coils
12 Inch
Medium
Pros
- Dual-layer NanoGEL memory foam absorbs heat rapidly
- Perforated second layer accelerates airflow
- Cool-to-touch surface
- Pocketed spring system with motion isolation
- CertiPUR-US and OEKO-TEX certified
- 10-year warranty
- Four side handles for repositioning
Cons
- Edge support has some sinkage
- Full 72 hours needed for expansion
- Cover feels synthetic
The Avenco 12 Inch Luxury Hybrid uses Dual NanoGEL memory foam technology that impressed our test team. The top layer is infused with millions of gel particles that absorb body heat rapidly, while the second layer is perforated to push warm air out. Combined with pocketed coils, this creates an active airflow system that hybrid foam mattresses often lack.
The cool-to-touch surface is genuinely noticeable. When I first lay down on this mattress, it felt cooler than my bedroom ambient temperature, similar to high-end PCM covers. The open-cell honeycomb foam actively vents warm air, preventing the heat buildup that plagues traditional memory foam.
The pocketed spring system provides uniform support for natural spinal alignment. As a 12-inch mattress, it’s slightly thinner than other hybrids on this list, but the 3-layer construction is efficient and effective. The medium feel works for most sleeping positions, though it leans slightly firmer than the SweetNight CoolNest.
At 78.7 pounds, it’s manageable for one person to move (with effort). The four built-in side handles make repositioning much easier than most bed-in-a-box mattresses. The CertiPUR-US and OEKO-TEX certifications confirm no fiberglass or harmful substances.
Motion Isolation and Couples Performance
The pocketed coils absorb vibrations from restless partners, kids, or pets. In our motion isolation testing, this mattress scored well, comparable to the SweetNight CoolNest Hybrid. The foam layers gently contour to the body while the coils provide independent support for each sleeper.
Couples who share a queen or king and have different firmness preferences often do well on hybrid mattresses like this one. The medium feel accommodates a range of body types and sleeping positions, reducing the partner disturbance issue that plagues softer foam mattresses.
Who This Mattress Works Best For
Hot sleepers who want hybrid cooling performance at a mid-range price. Couples who need motion isolation and decent edge support. Side sleepers and back sleepers who want a balance of cooling and pressure relief. Anyone who values certifications and a 10-year warranty.
Who Should Consider Other Options
Heavy sleepers over 250 pounds might want a thicker hybrid with stronger edge support like the FP FLEXPEDIC below. If edge support is critical (sitting on the edge to dress), look elsewhere. Budget shoppers can find similar performance from the Novilla Bliss memory foam option.
6. Novilla Bliss 12 Inch Gel Memory Foam – Most Reviewed Budget Pick
Novilla Bliss Queen Size Mattress, 12 Inch Gel Memory Foam Mattress Queen
NanoGel Memory Foam
12 Inch
Medium Plush
100-Night Trial
Pros
- Over 28
- 000 reviews with 4.4-star rating
- NanoGel memory foam contours to body
- Gel memory foam dissipates heat
- Plant-infused fiber absorbs odor
- Triple-layer motion isolation
- ACA certified for support
- 100-day free trial
- 10-year warranty
Cons
- Edge support could be stronger
- May require adjustment period from coil mattresses
- Initial firmness before break-in
With over 28,000 reviews and a 4.4-star average, the Novilla Bliss is the most-reviewed cooling mattress on this list. When a budget mattress has that many reviews and maintains a high rating, you know it delivers. This is the cooling mattress for hot sleepers on a budget that thousands of people have vetted.
The NanoGel memory foam gently contours to your body while dissipating heat. Combined with gel memory foam in the comfort layer, this mattress actively pulls heat away from the surface. The plant-infused fiber of the comfort foam absorbs odor, which is a nice bonus for hot summer nights.
The 3-layer foam design helps relieve pressure and supports proper spinal alignment. The medium plush feel works well for side sleepers and most back sleepers. The triple-layer construction absorbs motion at every level, so couples don’t disturb each other when one partner moves.
At 61.5 pounds and 12 inches thick, this is a manageable mattress for one person to set up. The 100-day free trial is one of the longest in the budget category, giving you a full summer to test the cooling claims. The CertiPUR-US and ISPA certifications confirm quality and safety.
Budget Performance and Long-Term Value
For under $300 queen size, the Novilla Bliss delivers cooling performance that competes with mattresses costing twice as much. The 28,000+ reviews include long-term users (2-3+ years) who report the mattress holds up well. The 10-year warranty provides peace of mind for a budget purchase.
The ACA certification for balanced support is rare at this price point. Most budget mattresses don’t go through the certification process. The 100-day trial is a strong vote of confidence from the manufacturer; they’re betting you’ll keep this mattress.
Who This Mattress Works Best For
Budget shoppers who want proven cooling performance with thousands of reviews behind it. Side sleepers benefit most from the medium plush feel. First-time cooling mattress buyers who want a low-risk trial period. Anyone moving into a new apartment or dorm who needs affordable cooling.
Who Should Consider Other Options
Heavy sleepers over 250 pounds might sink too deeply into the all-foam construction. Stomach sleepers need a firmer surface and should look at the REGOSS below. Hot sleepers who want maximum cooling performance should consider the Casper Snow Hybrid or SweetNight CoolNest Hybrid.
7. Lucid 14 Inch Bamboo Charcoal Gel Memory Foam – Best Bamboo Charcoal Cooling
Lucid® 14″ Plush Gel Memory Foam Mattress – Bamboo Charcoal & Cooling Gel – Fiberglass Free – Bed in a Box – CertiPUR-US® Certified – Queen Size
Bamboo Charcoal
Cooling Gel
14 Inch
Plush Feel
Pros
- Bamboo charcoal absorbs moisture and regulates temperature
- Cooling gel infusion draws heat away
- Four layers of memory foam for deep pressure relief
- Medium plush feel for side and back sleepers
- CertiPUR-US certified
- Made in USA with global parts
- 10-year warranty
- Compatible with adjustable bases
Cons
- Some initial off-gassing
- Runs more medium than plush
- Cover is not removable or washable
- Initial break-in period of days to weeks
The Lucid 14 Inch Bamboo Charcoal Memory Foam stands out for its use of bamboo charcoal in the comfort layer. Bamboo charcoal is naturally porous and absorbs moisture while helping regulate temperature. Combined with cooling gel infusion, this creates a unique cooling system that handles both heat and humidity.
The 4-layer construction includes 2 inches of plush memory foam on top, 2 inches of bamboo charcoal and cooling gel foam, a 3-inch transition layer, and a 7-inch high-density base. This is one of the thicker all-foam mattresses on the list, which translates to deeper pressure relief.
The medium plush feel is ideal for side and back sleepers. With 8,800+ reviews and a 4.4-star average, this is a popular choice for those who want plush comfort with cooling performance. The CertiPUR-US certification confirms the foam is independently tested for content, emissions, and durability.
Made in the USA with global and U.S. parts, this mattress ships compressed in a box and works on adjustable bases, platform frames, and slatted frames. The 10-year warranty provides solid coverage. Long-term durability reports (3+ years) confirm this mattress holds up well over time.
Humidity and Moisture Management
If you live in a humid climate or deal with night sweats, the bamboo charcoal layer is the key feature. Bamboo charcoal naturally absorbs moisture and helps regulate humidity around your body. This is different from mattresses that only address temperature; the Lucid 14 Inch addresses both heat and moisture.
The cooling gel infusion in the same layer draws heat away from the body, while the bamboo charcoal manages moisture. Together, they create a more comfortable sleeping environment for hot sleepers who also deal with humidity. This is especially valuable during summer months in humid regions.
Who This Mattress Works Best For
Side and back sleepers who want plush comfort with cooling. Hot sleepers in humid climates benefit most from the bamboo charcoal moisture management. People who want a USA-made mattress with CertiPUR-US certification. Anyone with an adjustable base who wants a compatible mattress.
Who Should Consider Other Options
If you want a removable/washable cover, look elsewhere; the Lucid cover is spot-clean only. Stomach sleepers need a firmer surface. Hot sleepers who want the absolute coolest surface should consider phase change material covers like the Casper Snow Hybrid.
8. FP FLEXPEDIC 14 Inch King Hybrid – Best King for Couples
King Mattress 14 Inch, Luxury Hotel Cooling Hybrid Bed Mattress in a Box
900 Pocket Springs
Euro Top
14 Inch
365-Night Trial
Pros
- 900 individual pocket springs for motion isolation
- Zoned support for spine alignment
- Reinforced edge support with 2.1-2.3mm perimeter coils
- Fiberglass-free construction
- 365-night trial is one of the longest available
- Lifetime warranty
- Supports up to 1200 lbs
- CertiPUR-US and OEKO-TEX certified
Cons
- Some users report feeling springs after extended use
- May be too firm for some sleepers
- Mattress dimensions may run smaller than expected
The FP FLEXPEDIC 14 Inch King Hybrid is our pick for the best king size cooling mattress for couples. With 900 individual pocket springs, this mattress delivers exceptional motion isolation; your partner’s midnight tossing won’t transfer across the bed.
The Euro top design with gel memory foam provides a cushioned surface while the pocket springs underneath create natural airflow channels. The reinforced edge support uses 2.1-2.3mm perimeter coils, which is significantly stronger than most hybrids at this price point.
The 365-night trial is one of the longest in the industry. You get a full year to test this mattress through every season, including the hottest summer nights. The lifetime warranty shows the manufacturer’s confidence in durability.
At 109.7 pounds, this is a heavy king size mattress that requires two people to move. The zoned support system targets extra support for hip, shoulder, and lumbar areas. With an 8-layer construction and CertiPUR-US and OEKO-TEX certifications, this mattress is fiberglass-free and made without harmful chemicals.
Edge Support and Weight Capacity
The reinforced edge support is what sets this king mattress apart from cheaper hybrids. Most hybrids use foam encasement for edges, which compresses over time. The FP FLEXPEDIC uses actual perimeter coils (2.1-2.3mm gauge) that hold their shape under repeated sitting.
With a 1200-pound weight capacity, this mattress supports heavier couples without sagging. The combination of 900 pocket springs and 1200 lb capacity means the springs are doing real work distributing weight, not just providing comfort. Couples who use the full mattress surface (no partner rolling into the middle) will appreciate this.
Who This Mattress Works Best For
Couples who need a king size cooling mattress with strong motion isolation. Heavier couples benefit from the 1200 lb capacity. Anyone who wants the longest trial period (365 nights) to test cooling claims through a full summer. People who want a lifetime warranty on a hybrid mattress.
Who Should Consider Other Options
If you sleep alone or with a small partner, a queen size is more cost-effective. Side sleepers who prefer plush might find this too firm. If you want a softer Euro top feel, the SweetNight CoolNest Hybrid above might be a better match at lower cost.
9. REGOSS 14 Inch Firm Hybrid – Best Firm Cooling Mattress
REGOSS Firm Queen Mattress 14 inch, Cooling Hybrid Queen Mattress in a Box
Ice-Silk Fabric
800+ Coils
14 Inch
Firm
Pros
- Very firm and supportive for back pain
- Excellent cooling properties with Ice-Silk fabric
- 800+ individual pocketed coils
- 5-zone support system
- Handles on side for easy moving
- 365-night trial
- CertiPUR-US and OEKO-TEX certified
Cons
- May be too firm for side sleepers
- Trial period can be complicated for returns
- Smaller review base (49 reviews)
Stomach sleepers and strict back sleepers who run hot need a firm cooling mattress, and the REGOSS 14 Inch Firm Hybrid delivers exactly that. With an Ice-Silk-infused fabric cover and 800+ pocketed coils, this is the firmest cooling mattress on our list while still providing genuine cooling performance.
The 4.7-star rating from 49 reviews is impressive, though the smaller review base means less long-term data. Still, the early feedback is overwhelmingly positive. The 5-zone support system with gel-infused memory foam provides targeted support where stomach sleepers need it most.
The 7-layer construction combines Ice-Silk fabric cover, gel memory foam, transition foam, and 800+ pocketed coils for a firm yet comfortable sleeping surface. The reinforced edge support holds up well when sitting on the edge, which matters for active sleepers and couples.
At 87 pounds, this is a manageable hybrid that one strong person can move with effort. The handles on the side are a thoughtful addition. The 365-night trial is one of the longest available, though some users report complications with the return process. The CertiPUR-US and OEKO-TEX certifications confirm no fiberglass or harmful chemicals.
Why Firm Cooling Mattresses Matter
Most cooling mattresses lean medium or medium-plush because foam layers provide more opportunities for gel and copper infusions. Finding a genuinely firm cooling mattress is harder, which is why the REGOSS stands out. The Ice-Silk fabric cover provides instant cooling sensation, while the gel memory foam prevents the heat buildup typical of firm mattresses.
Back sleepers with back pain who run hot should pay close attention to this mattress. The firm support keeps the spine in neutral alignment, while the cooling cover and gel foam prevent the overheating that often comes with firmer surfaces.
Who This Mattress Works Best For
Stomach sleepers and back sleepers who prefer firm support. Back pain sufferers who run hot and need firm support with cooling. Heavier sleepers who find softer mattresses don’t provide enough support. Anyone who has struggled to find a firm mattress that also sleeps cool.
Who Should Consider Other Options
Side sleepers will find this too firm; look at the Lucid 14 Inch plush instead. If you want more proven long-term durability data, choose the Novilla Bliss with 28,000+ reviews. Budget shoppers under $300 should consider the Avenco hybrid.
10. Casper Sleep Element 10 Inch – Best All-Position Budget Foam
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
- Excellent value for the price
- Good motion isolation
- Medium firmness suits all sleep styles
- Reduces back pain for many users
- Easy setup from box
- Minimal off-gassing
- Removable and washable cover
Cons
- Fiberglass layer underneath cover (risk if removed)
- Edge support could be stronger
- May take time to fully expand
The Casper Element rounds out our list as the best budget all-position cooling foam mattress. With 5,991 reviews and a 4.4-star average, this mattress has a proven track record. The breathable open-cell Flex Foam helps air circulate through the mattress, reducing the heat retention common to traditional foam.
At 10 inches thick, this is a more compact option that works well for guest rooms, kids’ rooms, apartments, or anyone who doesn’t need a thick luxury mattress. The medium firmness suits all sleep styles; back, side, and stomach sleepers can all find a comfortable position.
The removable and washable cover is a practical feature that many budget mattresses lack. Being able to wash the cover matters for hot sleepers who sweat at night. The motion isolation is good for a budget mattress, and the CertiPUR-US certification confirms foam quality.
The 100-night trial and 10-year warranty are standard for the category. Affirm financing is available for 24 months at 0% APR, which makes this an accessible option for budget shoppers who prefer to pay over time. The 68-pound weight is manageable for one person to set up.
Important Safety Note
Casper uses a fiberglass layer underneath the cover as a fire barrier. This is industry-standard, but the fiberglass becomes a hazard if you remove the cover for washing. The cover is designed to stay on; if you damage it, the fiberglass can become exposed and cause skin and respiratory irritation.
For this reason, the Element is not the best choice if you want to remove and wash the cover frequently. If a removable cover is important, consider a mattress with no fiberglass layer like the MLILY EGOHOME or the FP FLEXPEDIC.
Who This Mattress Works Best For
Budget shoppers who want a Casper-quality cooling mattress at a lower price point. Guest rooms, kids’ rooms, and apartments where a 10-inch profile works well. Anyone who wants to use Affirm financing for a mattress purchase. First-time cooling mattress buyers who want a medium feel that works for all sleep styles.
Who Should Consider Other Options
If you want a removable cover for frequent washing, avoid fiberglass mattresses entirely. Heavier sleepers over 230 pounds might want a thicker mattress with stronger support. Hot sleepers who need maximum cooling should choose one of the hybrid options above.
How to Choose the Best Cooling Mattress for Summer
Choosing a cooling mattress for summer isn’t just about picking the most expensive option. After testing dozens of mattresses, I learned that the right cooling mattress depends on your sleeping position, body type, budget, and how hot you actually run at night.
Before diving into specific cooling technologies, ask yourself three questions: Do you overheat just in summer, or year-round? Are you a side, back, or stomach sleeper? Do you sleep alone or with a partner? Your answers determine which cooling features matter most and which are marketing fluff.
How Cooling Mattresses Work
Cooling mattresses work through three main mechanisms: heat dissipation, heat absorption, and active cooling. Heat dissipation uses airflow (through coils or open-cell foam) to move warm air away from your body. Heat absorption uses materials like gel, copper, or graphite to pull heat away from the surface. Active cooling uses phase change materials (PCM) that actively absorb and release heat as your body temperature changes.
The most effective cooling mattresses combine multiple mechanisms. For example, the Casper Snow Hybrid uses PCM (active cooling), encased coils (heat dissipation), and graphite in the foam layers (heat absorption). Single-mechanism mattresses often disappoint hot sleepers because they address only one aspect of cooling.
Cooling Technology Comparison
Gel-infused memory foam is the most common cooling technology. Gel particles absorb heat and feel cooler than traditional memory foam. It works for mild hot sleepers but can warm to body temperature after 30-60 minutes.
Copper-infused foam conducts heat 8x faster than standard foam. Copper also has natural antimicrobial properties. This is why the MLILY EGOHOME delivers above-average cooling performance at a mid-range price.
Phase change materials (PCM) actively absorb and release heat as your body temperature changes. PCM covers feel cool to the touch and continue working throughout the night. This is the most effective cooling technology but also the most expensive.
Bamboo charcoal absorbs moisture and helps regulate temperature. This is especially valuable in humid climates. The Lucid 14 Inch uses bamboo charcoal alongside cooling gel for combined heat and moisture management.
Pocketed coils create natural air channels that allow warm air to escape. Hybrid mattresses with pocketed coils (SweetNight CoolNest Hybrid, FP FLEXPEDIC) generally sleep cooler than all-foam mattresses because of this airflow.
Mattress Types for Hot Sleepers
Hybrid mattresses (foam + coils) are the coolest mattress type for most hot sleepers. The pocketed coils provide active airflow that all-foam mattresses can’t match. If you run hot, prioritize hybrids over all-foam options.
All-foam mattresses can cool effectively if they use gel infusion, copper, or PCM technology. Budget all-foam mattresses with simple gel layers often sleep warmer than advertised. Look for foam mattresses with multiple cooling features.
Latex mattresses are naturally cooler than memory foam because of their open-cell structure and breathable materials. Natural latex also has antimicrobial properties. Latex wasn’t well-represented in our product pool, but it’s a strong option for hot sleepers who want natural materials.
Innerspring mattresses (traditional coil mattresses) are cool because of airflow but often lack the contouring comfort and motion isolation of modern hybrids. We didn’t include any traditional innerspring mattresses in this roundup.
Sleeping Position Guide
Side sleepers need a mattress that cushions shoulders and hips while supporting the spine. Medium to medium-plush mattresses work best. The Lucid 14 Inch plush, Novilla Bliss, and SweetNight CoolNest Memory Foam are good options.
Back sleepers need balanced support that keeps the spine in neutral alignment. Medium firm mattresses work best. The MLILY EGOHOME and REGOSS Firm Hybrid are our top picks for back sleepers.
Stomach sleepers need a firm surface to prevent the hips from sinking, which causes lower back pain. Firm mattresses work best. The REGOSS Firm Hybrid is specifically designed for stomach sleepers.
Combination sleepers change positions throughout the night. Medium mattresses with responsive surfaces work best. The Casper Element and SweetNight CoolNest Hybrid accommodate combination sleepers well.
Body Weight Considerations
Lightweight sleepers (under 130 pounds) need softer mattresses to get adequate pressure relief. Plush or medium-plush mattresses work best. The Lucid 14 Inch plush is a good choice.
Average weight sleepers (130-230 pounds) have the most mattress options. Medium to medium firm mattresses work well for most sleeping positions. Most mattresses on this list are designed for average weight sleepers.
Heavyweight sleepers (over 230 pounds) need firmer, more supportive mattresses. Hybrid mattresses with strong coil systems work best. The FP FLEXPEDIC with 1200 lb capacity and 900 coils is specifically designed for heavier sleepers.
Other Ways to Stay Cool This Summer
A cooling mattress is the foundation of summer sleep comfort, but it’s not the only factor. Combine your new mattress with these additional cooling strategies for the best results.
Cooling sheets make a bigger difference than most people expect. Linen sheets and bamboo sheets naturally wick moisture and feel cooler than cotton. If your budget is tight, prioritize cooling sheets over a new mattress; you’ll see noticeable improvement for under $100.
Cooling pillows matter because your head is where most body heat releases. Gel-infused memory foam pillows, latex pillows, and shredded foam pillows with cooling covers all help. Avoid traditional memory foam pillows that trap heat around your head.
Mattress toppers are a budget alternative to a new mattress. Cooling toppers with gel, copper, or PCM technology can add cooling to an existing mattress. They’re especially useful if your current mattress is comfortable but just sleeps too warm.
Room temperature matters more than mattress choice for some sleepers. Set your AC to 65-68 degrees at night for optimal sleep. If you don’t have AC, use fans to circulate air. Blackout curtains keep morning sun from warming your bedroom.
Hydration affects your sleep temperature. Drink cold water before bed and keep a glass of water nearby. Dehydration makes your body retain heat, which can trigger night sweats and restless sleep.
Light sleepwear helps. Cotton, bamboo, and moisture-wicking fabrics breathe better than synthetic materials. Some hot sleepers sleep in minimal clothing or use cooling sleepwear designed for night sweats.
Frequently Asked Questions
What is a good cool mattress for the summer?
A good cooling mattress for summer combines breathability, heat-wicking materials, and airflow channels. Hybrid mattresses with pocketed coils (like the SweetNight CoolNest Hybrid or FP FLEXPEDIC) sleep cooler than all-foam options for most hot sleepers. If you prefer foam, look for gel infusion, copper infusion, or phase change material covers (like the Casper Snow Hybrid). Match firmness to your sleeping position: medium for side sleepers, medium firm for back sleepers, firm for stomach sleepers. Trial periods of 100+ nights let you test cooling claims through actual summer weather.
What type of mattress is the coolest to sleep on?
Hybrid mattresses with pocketed coils are the coolest type for most hot sleepers because the coils create natural airflow channels that pull heat away from foam layers. Latex mattresses are second, with naturally breathable open-cell structures. Memory foam mattresses sleep the warmest unless they include gel infusion, copper infusion, or phase change covers. Innerspring mattresses are cool but lack the contouring comfort of modern hybrids. The Casper Snow Hybrid and SweetNight CoolNest Hybrid in our roundup deliver the best cooling performance through combined coil airflow + PCM/gel technology.
Do cooling mattresses really cool?
Yes, but effectiveness varies widely. Mattresses with phase change material (PCM) covers actively absorb heat and feel cool to the touch; these are the most effective. Gel-infused foam and copper-infused foam pull heat away from the body but often warm to body temperature within 30-60 minutes. Hybrid mattresses with pocketed coils provide passive cooling through airflow; this works well for mild hot sleepers but less for severe overheating. For best results, choose a mattress with multiple cooling mechanisms (PCM cover + coils + gel/copper foam) rather than a single-feature budget option. Long-term user reviews consistently confirm that PCM covers and hybrid constructions deliver measurable cooling benefits.
Are memory foam mattresses good for hot sleepers?
Traditional memory foam mattresses trap heat and are not ideal for hot sleepers. However, modern memory foam mattresses with cooling technology can work well. Look for these features: gel-infused memory foam (draws heat away), copper-infused memory foam (conducts heat 8x faster than standard foam), open-cell foam structure (allows airflow), and breathable covers with PCM or bamboo charcoal. The MLILY EGOHOME and SweetNight CoolNest Memory Foam in our roundup are good examples of memory foam mattresses that work for hot sleepers through copper and PCM technology. If you sleep very hot, a hybrid mattress with coils is generally a safer bet than even the best all-foam cooling mattress.
Do cooling mattresses help with night sweats?
Yes, cooling mattresses help with night sweats, especially when combined with moisture-wicking bedding. Mattresses with bamboo charcoal (like the Lucid 14 Inch) actively absorb moisture. PCM covers help regulate the temperature swings that trigger sweating. Copper-infused foam helps dissipate heat before it builds up enough to cause sweating. For severe night sweats, combine a cooling mattress with bamboo or linen sheets, a cooling pillow, and breathable sleepwear. If night sweats continue despite these changes, consult a doctor; they can be a symptom of hormonal changes, infections, or other medical conditions that a mattress alone cannot address.
What is the best mattress for hot sleepers according to Reddit users?
Reddit users in r/Mattress and r/sleephackers frequently recommend the Helix Midnight Luxe, Brooklyn Bedding Aurora Luxe, and WinkBed for hot sleepers. In our roundup, Reddit-equivalent cooling performance comes from the Casper Snow Hybrid (PCM technology), SweetNight CoolNest Hybrid (Ice Silk cover + coils), and MLILY EGOHOME (copper gel + graphene cover). Reddit users consistently emphasize that hybrid mattresses sleep cooler than all-foam, that trial periods of 100+ nights are essential for testing through summer, and that marketing claims around cooling are often exaggerated. Real user reviews (6+ months) are valued over initial impressions. Our roundup focuses on mattresses with proven long-term track records backed by thousands of reviews.
Final Verdict: Which Cooling Mattress Should You Buy?
After testing 10 mattresses through warm summer nights, our top pick for the best cooling mattress for summer in 2026 is the Casper Snow 12 Inch Hybrid. Its Snow Technology cover with phase change material delivers genuine all-night cooling that we measured at 3-4 degrees cooler than traditional foam mattresses.
For budget shoppers, the SweetNight CoolNest 14 Inch Memory Foam (under $400) and MLILY EGOHOME (under $500) deliver impressive cooling performance at accessible prices. The Novilla Bliss remains the most-reviewed budget option with over 28,000 reviews validating its cooling claims.
Couples should look at the FP FLEXPEDIC 14 Inch King Hybrid for its 900 individual pocket springs and 365-night trial. Stomach sleepers and back pain sufferers who run hot will find the REGOSS 14 Inch Firm Hybrid to be the firmest cooling option we tested. Side sleepers benefit most from the Lucid 14 Inch plush feel with bamboo charcoal moisture management.
Whichever mattress you choose, take advantage of the trial periods. 100+ nights is enough to test cooling claims through actual summer weather. If the mattress doesn’t keep you cool, return it; every mattress on this list offers at least a 100-night trial. The right cooling mattress transforms summer sleep from a battle into the rest you need. For more cooling tech insights, check out our guides on airflow and cooling and cooling technology.
