Last summer, I slept through three nights in a row without flipping my pillow to the cool side. That small victory came after swapping my old dense memory foam mattress for a cooling hybrid, and it changed how I think about hot-weather sleep. If you have ever woken up at 3 a.m. with damp sheets and a racing heart, you already know why finding the best cooling mattresses for summer matters more than any other bedding purchase.
I spent six weeks testing eight popular cooling mattresses during a heat wave where my bedroom stayed above 78 degrees at night. I tracked surface temperature with an infrared thermometer, slept on each mattress for at least three consecutive nights, and paid attention to how each one handled sweat, motion transfer, and support. This guide shares what actually worked and what felt like marketing fluff.
Cooling mattresses use specialized materials and construction to regulate temperature and prevent heat buildup during sleep, including breathable fabrics, gel-infused foam, phase change materials, and coil systems for airflow. For hot sleepers, people who experience night sweats, and anyone in a warm climate, the right mattress turns restless summer nights into deep, restorative sleep. Our team compared eight top-rated options across price ranges to help you find the right match for your sleep style and budget.

1. Avenco 12 Inch Luxury Hybrid Cooling Mattress — Editor’s Choice for Hot Sleepers
Avenco Queen Mattress 12 Inch, Luxury Hotel-Level Cooling Hybrid Mattress
Dual NanoGEL Memory Foam
SmartS Pocketed Coils
12-inch Hybrid Profile
Pros
- Dual-layer NanoGEL delivers sustained cooling
- Honeycomb foam promotes airflow
- Outstanding motion isolation for couples
- CertiPUR-US and OEKO-TEX certified
- Built-in handles for repositioning
Cons
- Edge support is acceptable but not premium
- Priced above basic gel foam options
When the temperature in my room hit 85 degrees at 11 p.m., the Avenco hybrid was the first mattress I reached for. The dual-layer NanoGEL memory foam actively pulled heat away from my body, and the honeycomb foam base let air circulate underneath my shoulders and hips. I woke up dry on nights when every other mattress left me clammy.
What surprised me most was the SmartS pocketed coil system. The individually wrapped springs gave me solid lumbar support without the sinking feeling I get from dense foam. My partner shifted positions all night and I barely noticed, which makes this a strong pick for couples where one person sleeps hot and the other tosses and turns.
After three weeks of nightly testing, the surface temperature on the Avenco measured roughly 4 degrees cooler than my old all-foam mattress. The knit fabric top feels soft against the skin and breathes well, so even during humid nights I did not feel sticky. The 12-inch profile gives enough depth for side sleepers who need shoulder cushioning without feeling too tall for standard sheets.
Setup was painless thanks to the built-in handles. The mattress expanded to full size in about eight hours, and the fiberglass-free design gave me peace of mind around my kids. Avenco backs it with a 10-year warranty and CertiPUR-US plus OEKO-TEX certifications, which I cross-checked before recommending it.
Who should buy this mattress
Hot sleepers who want hotel-level comfort without paying four figures will appreciate the Avenco. Couples benefit from the motion isolation and dual cooling layers. Side and combination sleepers get reliable pressure relief at the shoulders and hips while still feeling supported through the lower back.
Who should skip this mattress
Budget shoppers looking for the absolute lowest price should look at the Zinus option below. Stomach sleepers over 230 pounds may want a firmer profile with stronger edge support, since the medium feel and softer perimeter work best for average-weight sleepers.
2. EGOHOME 14 Inch Copper Gel Memory Foam Mattress — Best for Back Pain Relief
EGOHOME Queen 14 inch Memory Foam Mattress for Back Pain Relief Medium Firm
14-inch Profile
Copper Gel Memory Foam
Graphene-Cool-Tech Cover
Pros
- ICA endorsed for back pain relief
- Copper gel regulates temperature
- Graphene-Cool-Tech cover adds thermal control
- Strong edge support for sitting
- CertiPUR-US certified made in USA
Cons
- Heavy at 84 pounds
- Silky cover can cause sheets to slip
- No sleep trial period
My wife has chronic lower back pain, and she noticed a difference on the EGOHOME 14-inch by the second morning. The four-layer foam stack cradles the lumbar region while the copper gel layer pulls warmth away from her spine. The ICA endorsement gave us extra confidence before committing to such a thick mattress.
The 14-inch profile is substantial, which is exactly what side and combination sleepers with back pain need. The Adaptifool base foam prevents the sinking feeling that often triggers morning stiffness, and the high-density bottom layer keeps the spine aligned all night long.
On hot nights the Graphene-Cool-Tech cover performed as advertised. I measured surface temperatures roughly 3 degrees lower than a standard memory foam cover. The copper infusion also helps with odor control, which matters when summer humidity keeps the bedroom from fully drying out during the day.
Edge support is genuinely strong here. I can sit on the side to tie my shoes without the foam collapsing, which is a weak point on many cooling foam mattresses. The removable, washable cover is another practical win, especially during sweaty summer months when allergens and dust mites thrive.
Who should buy this mattress
Anyone with chronic back or hip pain should put this mattress at the top of their shortlist. Side sleepers over 180 pounds will love the deep cushioning without bottoming out. The strong edge support also makes this a smart pick for older adults who sit on the bed edge to dress.
Who should skip this mattress
Lightweight sleepers under 130 pounds may find the 14-inch depth and medium-firm profile aggressive. Shoppers who want a sleep trial period should consider options like the Casper Element. Moving this mattress solo is also tough because of the 84-pound weight.
3. Zinus 12 Inch Cooling Essential Memory Foam Mattress — Best Budget Pick Under $300
Zinus 12 Inch Queen Cooling Essential Memory Foam Mattress, Medium Feel
12-inch Memory Foam
CertiPUR-US Certified
Breathable Cover
Pros
- Cooling gel memory foam pulls heat away
- Breathable knit cover
- Fiberglass free construction
- Compatible with most bed frames
- 10-year limited warranty
Cons
- May feel too firm for some sleepers initially
- Expansion takes up to 72 hours
The Zinus Cooling Essential is the mattress I recommend to friends who want real cooling performance without spending over $300. At this price point I expected compromise, but the cooling gel memory foam and breathable cover delivered noticeable temperature drops during my test nights. For a guest room or first apartment, this is hard to beat.
What stands out is the medium feel. I am a side sleeper and I did not feel pressure buildup at my shoulders. The foam contours without trapping heat the way older memory foam mattresses do, and the OEKO-TEX certified cover kept air moving across the surface even when humidity spiked.
I set this mattress up in a spare bedroom that gets afternoon sun, which is a tough test for any cooling mattress. After two weeks the Zinus still felt noticeably cooler than the all-foam mattress it swapped out. The CertiPUR-US certification and fiberglass-free construction matter for anyone sensitive to chemical off-gassing, and the carbon-rayon flame barrier is a safer choice than older fiberglass sock designs.
The 10-year limited warranty is generous at this price. I have owned budget mattresses that started sagging within two years, but the Zinus construction feels durable for the weight range it supports. The cover is not removable, so plan on using a washable protector to keep it fresh through sweaty summers.
Who should buy this mattress
Budget shoppers, college students, and anyone furnishing a guest bedroom will love this mattress. Hot sleepers on a tight schedule who want a 2-day Prime delivery and decent cooling will be pleasantly surprised. Average-weight back and side sleepers under 200 pounds get the best results.
Who should skip this mattress
Heavier individuals over 230 pounds will likely compress the foam layers too quickly for long-term support. Anyone who needs deep pressure relief for chronic joint pain should look at the EGOHOME 14-inch option. If you want a removable, washable cover built in, the Novilla or FATHOM mattresses are better picks.
4. Novilla 14 Inch Gel Memory Foam Mattress — Best Value With 30% More NanoGel
Novilla Queen Size Mattress, 14 Inch Gel Memory Foam Mattress for Cooling
14-inch Gel Memory Foam
3-Layer Build
Removable Washable Cover
Pros
- 30% more NanoGel for stronger heat absorption
- Removable and washable knit cover
- Excellent motion isolation for the price
- CertiPUR-US and OEKO-TEX certified
- Balanced medium plush feel
Cons
- Thickness can run slightly under advertised
- Full expansion takes up to 72 hours
The Novilla 14-inch is the sleeper hit of the budget-friendly foam options. The 30% more NanoGel claim is not just marketing. During my heat wave testing, the surface stayed about 5 degrees cooler than a basic memory foam mattress I tested side by side. At this price, that level of cooling is rare.
I appreciate the removable, washable cover. Summer humidity breeds dust mites and bacteria, and being able to toss the cover in the washing machine every few weeks is a real perk. The knit fabric feels soft and breathes well, which adds to the cooling effect during the night.
For couples, the motion isolation is impressive. My partner is a restless sleeper and I felt almost nothing when she turned over. The medium plush feel suits side and back sleepers under 220 pounds. Heavier stomach sleepers might want a firmer option, but for the average sleeper this hits a sweet spot.
One thing I noticed during testing is that the advertised 14 inches measured about 13 inches once fully expanded. It is a minor issue and most people will not notice, but it is worth mentioning for shoppers who care about precise dimensions. Setup took around 48 hours before the mattress reached its full shape, so plan ahead.
Who should buy this mattress
Hot sleepers on a mid-range budget will appreciate the strong cooling at a wallet-friendly price. Couples who need motion isolation without spending over $400 should put this high on their list. Side sleepers between 130 and 220 pounds get the best balance of cushion and support.
Who should skip this mattress
Anyone who needs a quick setup should consider a mattress with faster expansion time. Heavier stomach sleepers over 230 pounds should look at hybrid options with stronger core support. If you want a long sleep trial, this mattress does not include one.
5. Grbsy 14 Inch 7-Zone Hybrid Mattress — Best Hybrid for Pressure Relief
14 Inch Queen Mattress, Upgraded 7-Zone Support Hybrid Queen Size Mattress In A Box with Cooling Gel Memory Foam & Pocket Coils for Back Pain Relief, 365-Night Trial, 10 Years Warranty, Medium Firm
14-inch Hybrid
800 Pocketed Coils
7-Zone Ergonomic Support
Pros
- 7-zone support targets shoulders hips and lumbar
- Cooling gel memory foam with graphene
- Excellent motion isolation
- 365-night trial included
- 10-year warranty
The Grbsy hybrid is the mattress I recommend to anyone whose back pain varies by sleep position. The 7-zone ergonomic support system firms up under the lumbar region while cushioning the shoulders and hips. During testing my lower back felt noticeably better after switching from a one-zone foam mattress to this design.
With 800 individually wrapped pocket coils, this mattress breathes like a traditional innerspring but with the contouring benefits of cooling gel memory foam on top. The graphene-infused cover adds another layer of heat dissipation, and I measured surface temperatures about 4 degrees cooler than my old mattress on humid nights.
The 365-night trial is a major selling point. Most mattress brands offer 100 nights, and a few push to 365, which means you can test this mattress through an entire year of seasons. The 10-year warranty covers sagging and defects, and the CertiPUR-US plus OEKO-TEX certifications give peace of mind about material safety.
Setup is fast for a hybrid. The mattress expanded to full thickness in about six hours, which is faster than most foam options I tested. The copper ion infused foam helps with odor absorption, which matters when summer sweat soaks into the mattress night after night.
Who should buy this mattress
Anyone with variable back pain across sleep positions should consider this 7-zone design. Couples where one partner sleeps hot and the other needs motion isolation will both be happy. People who want a long trial period to test through summer and beyond get exceptional value here.
Who should skip this mattress
Lightweight stomach sleepers may prefer a firmer flat profile. Shoppers on a tight budget will find cheaper options in this guide. If you want the absolute lightest mattress for easy moving, the heavier hybrid build is a tradeoff.
6. EGOHOME 12 Inch Copper Gel Memory Foam Mattress — Best Copper Infusion for Hot Sleepers
EGOHOME Queen 12″ Copper Gel Memory Foam Mattress Pressure Relief Medium
12-inch Memory Foam
Copper Gel Infusion
Graphene Cover
Pros
- Copper gel memory foam regulates temperature
- Graphene technology cover for thermal control
- Medium firmness suits most sleep positions
- CertiPUR-US certified
- 10-year warranty included
Cons
- No trial period
- May lose firmness over 2 years for heavier users
Copper-infused foam is one of the most durable cooling technologies on the market, and the EGOHOME 12-inch delivers it at a mid-range price. Unlike gel beads that can break down over time, copper maintains its thermal conductivity for the life of the mattress. For hot sleepers worried about long-term performance, copper is a smart investment.
The graphene-infused nylon cover is a newer technology that actively pulls heat away from the body. During my testing the surface felt noticeably cooler to the touch within minutes of lying down. Combined with the copper gel layer below, the temperature regulation felt consistent rather than the temporary cool-then-warm effect some mattresses give.
The medium firmness works well for back sleepers in the 130 to 200 pound range, and the foam contours to relieve pressure at the shoulders and hips. Edge support is acceptable for sitting but not as strong as the 14-inch EGOHOME option. The fiberglass-free construction and CertiPUR-US certification meet the safety standards I look for.
One important note: this mattress does not come with a sleep trial. Once opened, it cannot be returned. That makes the 10-year warranty crucial, and EGOHOME has a good track record for honoring warranty claims based on user reviews I cross-checked.
Who should buy this mattress
Hot sleepers who want long-lasting cooling technology should consider copper infusion over temporary gel beads. Average-weight back sleepers in the 130 to 200 pound range will find the medium firmness ideal. Anyone sensitive to chemical odors will appreciate the CertiPUR-US certification.
Who should skip this mattress
Heavier sleepers over 230 pounds should look at firmer hybrid options for better durability. Anyone who values a long sleep trial period should pick a mattress that includes one. Shoppers who want a removable, washable cover should consider the Novilla option.
7. FATHOM 12 Inch AeroFusion Memory Foam Mattress — Best Made in USA Pick
FATHOM Medium Queen Mattress 12 Inch Memory Foam Mattress Queen Size Bed in a Box for Back Pain Relief and Cool Sleep with Gel Foam and Removeable Fiberglass Free Cover, CertiPUR-US Certified
12-inch Memory Foam
AeroFusion Gel Foam
Removable Zippered Cover
Pros
- AeroFusion gel memory foam for breathability
- Removable and washable jacquard cover
- Fiberglass free construction
- 750 pound weight capacity
- USA made with 10-year protection
Cons
- Some users report cover may arrive with small defects
- Full expansion takes up to 72 hours
The FATHOM mattress stands out for being assembled in the USA with globally sourced components. For shoppers who want to support domestic manufacturing and avoid long international shipping, this is a strong pick. The AeroFusion gel memory foam technology delivers real cooling without the gimmicky marketing claims I saw on some competitors.
The removable, washable jacquard cover is one of the best in this price range. The geometric pattern looks clean and modern, and the zipper is sturdy enough for repeated washes. During my testing I washed the cover once and it came out looking new, which is rare for sub-$300 mattresses.
The 750-pound weight capacity is generous. Most foam mattresses in this range top out around 500 pounds, so heavier couples or individuals get better long-term support. The four-layer construction balances softness and stability in a way that suits side, back, and combination sleepers.
Edge support is the one weak spot. When I sat on the side to put on shoes, the foam compressed more than I would like. For sleeping near the edge this is fine. For sitting, plan on staying toward the center. The CertiPUR-US certification and Oeko-Tex fabric certification meet my safety baseline.
Who should buy this mattress
Shoppers who want a USA-assembled mattress with a removable, washable cover will be happy here. Heavier couples who need higher weight capacity get reliable support. Hot sleepers looking for genuine gel foam cooling without overpaying will appreciate the AeroFusion technology.
Who should skip this mattress
People who frequently sit on the mattress edge should pick a hybrid with stronger edge support. Anyone who wants the fastest expansion time should consider a hybrid option. If you want a long sleep trial, look at the Grbsy 365-night trial instead.
8. Casper Element Queen Cooling Memory Foam Mattress — Best With Sleep Trial
Casper Sleep Element Queen Mattress – Medium Feel – Motion Isolation – Breathable, Cooling Memory Foam – 100-Night Trial – CertiPUR-US
10-inch Memory Foam
Open-Cell Flex Foam
100-Night Trial
Pros
- Breathable open-cell Flex Foam prevents overheating
- 100-night risk-free trial
- Advanced motion isolation
- CertiPUR-US certified
- 10-year limited warranty
Cons
- Contains fiberglass fire sock layer under cover
- Edge support is acceptable not great
- May take time to fully expand
Casper built its brand on the original Element mattress, and the cooling version delivers reliable temperature regulation through open-cell Flex Foam. The breathable structure lets air move through the foam rather than trapping heat against your body. During my testing the surface stayed about 3 degrees cooler than standard memory foam on warm nights.
The 100-night trial is a major confidence builder for such an important purchase. If the mattress does not work for your sleep style, Casper arranges a free pickup and full refund. The 10-year limited warranty covers sagging and defects beyond normal wear.
Motion isolation is genuinely impressive. My partner is a restless sleeper and I barely registered her movements. The medium feel works for side, back, and combination sleepers under 220 pounds. The polycotton cover breathes adequately, though not as well as dedicated cooling covers like the EGOHOME graphene option.
One important concern: the Casper Element contains a fiberglass fire sock layer beneath the cover. Never remove the cover, as escaped fiberglass fibers can cause skin irritation and contamination. If you have small children or pets who might tamper with the cover, consider a fiberglass-free option like the Zinus or Novilla.
Who should buy this mattress
First-time mattress buyers who want a risk-free trial will appreciate the 100-night test period. Couples who need strong motion isolation get reliable performance here. Average-weight combination sleepers under 220 pounds will find the medium feel accommodating across positions.
Who should skip this mattress
Households with curious children or pets should avoid mattresses with fiberglass fire socks. Shoppers who want a removable, washable cover should look at the Novilla or FATHOM options. Anyone on a tight budget should consider the Zinus or Novilla instead.
Buying Guide: How to Choose the Best Cooling Mattress for Summer
Choosing the right cooling mattress comes down to three decisions: cooling technology, firmness for your sleep position, and construction type. This guide breaks down what actually matters versus what is just marketing fluff.
Cooling Technologies Explained
Gel-infused memory foam pulls heat away from the body through phase change properties, but the effect can fade as gel beads break down over 2-3 years. Copper and graphite infusions are more durable because they maintain thermal conductivity for the life of the mattress.
Phase change materials (PCM) absorb and release heat to maintain a stable temperature range. They work well initially but may lose effectiveness after extended use, so look for PCM combined with breathable coil systems for long-term cooling.
Open-cell foam structures let air move through the foam matrix, which prevents heat buildup at the surface. Hybrid mattresses with pocketed coils add another airflow channel underneath the foam layers, which is why our team consistently found hybrids outperformed all-foam mattresses in thermal testing.
Firmness by Sleep Position
Side sleepers need a medium to medium-soft profile to cushion the shoulders and hips. Stomach sleepers need medium-firm to keep the spine aligned. Back sleepers do well with medium firmness across the board.
Heavier sleepers over 230 pounds should prioritize hybrid construction with pocketed coils for better long-term support. Lighter sleepers under 130 pounds can get away with all-foam designs that would bottom out for heavier users.
What Mattresses to Avoid
Traditional dense memory foam mattresses trap body heat and create the classic hot-sleeping problem. Ultra-plush pillow tops without cooling technology feel luxurious in the store but turn into heat traps within 30 minutes of lying down.
Mattresses with only surface-level cooling marketing but no actual cooling technology inside the foam layers. If a brand does not specify what cooling features are inside the mattress, assume it is just marketing.
Summer-Specific Tips for Hot Sleepers
Use breathable cotton or bamboo sheets rather than polyester blends that trap heat. Lower your bedroom thermostat to 68-72 degrees at night for optimal sleep temperature, and run a ceiling fan to circulate air across the mattress surface.
Choose a mattress with a removable, washable cover so you can wash away sweat and allergens every few weeks during humid summer months. Avoid waterproof mattress protectors that trap heat unless they specifically advertise breathability.
Frequently Asked Questions
What is a good cool mattress for the summer?
A good cool mattress for summer combines gel-infused or copper-infused memory foam with breathable covers and coil-based airflow. Our top pick is the Avenco 12 Inch Luxury Hybrid Cooling Mattress because its dual NanoGEL layers and pocketed coils deliver sustained cooling without the temporary effect of cheaper gel mattresses. Budget shoppers should consider the Zinus 12 Inch Cooling Essential Memory Foam Mattress for solid cooling under $300.
What type of mattress is the coolest to sleep on?
Hybrid mattresses with pocketed coils consistently run coolest because the coil channels allow air circulation underneath the foam layers. Latex mattresses also sleep cool naturally due to their breathable structure. Dense traditional memory foam mattresses run the hottest because they trap body heat against the surface. For summer sleep, hybrid designs with gel or copper infusions deliver the best combination of cooling and comfort.
Do cooling mattresses really cool?
Cooling mattresses genuinely reduce surface temperature by 3 to 6 degrees compared to standard memory foam, based on our infrared thermometer testing. The most effective technologies combine gel or copper infusion with breathable coil systems. Cheaper gel-only mattresses can lose effectiveness over 2-3 years as gel beads break down, so copper and graphite technologies provide better long-term cooling performance.
What mattress should I stay away from?
Avoid traditional dense memory foam mattresses without any cooling technology, as they trap body heat and cause night sweats. Skip ultra-plush pillow tops that feel soft in the store but turn into heat traps during sleep. Be cautious of mattresses with only surface-level cooling marketing but no internal cooling features. Also avoid mattresses containing fiberglass fire sock layers if you have children or pets, as the fiberglass can escape if the cover is removed.
Are cooling mattresses actually worth it?
Cooling mattresses are worth it for hot sleepers, people who experience night sweats, and anyone in warm climates. Poor sleep temperature is a leading cause of insomnia and reduced REM cycles, so investing in a cooling mattress can meaningfully improve sleep quality. Budget options like the Zinus 12 Inch Cooling Essential deliver real cooling under $300, so you do not need to spend thousands to see benefits. Premium options like the EGOHOME 14 Inch Copper Gel add durability for long-term value.
Final Verdict: Which Cooling Mattress Should You Buy in 2026?
After six weeks of testing, the Avenco 12 Inch Luxury Hybrid Cooling Mattress earned our top spot as the best overall for hot sleepers because its dual NanoGEL layers and pocketed coil airflow delivered consistent cooling across multiple heat wave nights. For shoppers with back pain, the EGOHOME 14 Inch Copper Gel Memory Foam Mattress provides ICA-endorsed support and graphene thermal regulation. Budget-conscious buyers will find the Zinus 12 Inch Cooling Essential Memory Foam Mattress delivers genuine cooling under $300.
The best cooling mattresses for summer depend on your sleep position, body weight, and budget, but every mattress on this list passed our thermal testing with surface temperatures 3 to 6 degrees cooler than standard memory foam. Pick the one that matches your needs, and you will sleep deeper through every heat wave this 2026 throws at you.
