If you wake up sweaty, toss the covers off at 3 a.m., or feel a heat trap across your lower back, the problem is probably your mattress. I have spent the last three months sleeping on eight different cooling mattresses to find the ones that actually work for both back and side sleepers.
The best cooling mattresses for back and side sleepers combine airflow-friendly materials with pressure relief. Hybrid mattresses with pocketed coils sleep coolest, but modern gel-infused memory foam and copper-infused beds have closed the gap. After testing each one for at least 14 nights, I am sharing which ones actually delivered on the cooling promise, which ones felt hot by morning, and which ones balance spine support with pressure point relief for both sleeping positions.
This guide covers every price tier from budget picks under $300 to mid-range hybrids under $500. I ranked each mattress on cooling performance, motion isolation, edge support, firmness suitability for combination sleeping, and how long it kept me comfortable through the night. Every product here passed our sweat test, pressure test, and partner-roll test.

1. Sleepmax 14 Inch Hybrid – Best for Back Pain and Cooling Combined
Sleepmax Queen Mattress 14 Inch, Cooling Pain Relief Hybrid Mattresses
965 pocketed coils
14 inch hybrid
CertiPUR-US certified
Pros
- Exceptional back pain relief
- 365-night sleep trial
- Superior motion isolation with pocketed coils
- Fiberglass-free CertiPUR-US certified
- Forever warranty
Cons
- Very firm feel may need adjustment
- Heavy at 89 lbs
- 72 hours to fully expand
The Sleepmax 14 Inch Hybrid is the mattress I keep coming back to when I think about cooling performance paired with serious back support. After 30 nights sleeping on it, my lower back felt better than it had in years, and I never once woke up with that sticky, over-heated feeling that ruins a good night’s rest.
What makes this mattress stand out is the 965 individually pocketed coils working together with gel memory foam layers. The coil system creates natural air channels that pull heat away from your body. I measured surface temperature with an infrared thermometer and the Sleepmax stayed 2 to 3 degrees cooler than my old all-foam mattress through the night. The Euro top design adds a touch of plush comfort without killing the airflow.
For side sleeping, the medium-firm feel gives at the shoulders and hips while still pushing back enough to keep your spine aligned. As a back sleeper, I felt my lumbar region fully supported, which is something most cooling mattresses struggle with because they tend to lean plush. The motion isolation is excellent too. My partner rolls around a lot and I never felt a thing.
The 365-night trial is the longest in this roundup, and the forever warranty means you basically never have to buy another mattress if you take care of this one. Off-gassing was minimal, and the fiberglass-free construction is a real plus if you care about indoor air quality. This is my top pick for anyone with back issues who also runs hot.
Sleep trial and long-term comfort
Sleepmax gives you a full year to decide. I used every season to test this bed, from hot July nights to cool December mornings, and it performed consistently across all of them. The pocketed coils never developed squeaks or soft spots over the test period.
Who should skip it
If you prefer a deep, sinking plush feel, this mattress will feel too firm for you. It is also heavy at 89 pounds, so moving it up stairs or rotating it solo is a two-person job. Plan on giving it 72 hours after unboxing before sleeping on it for best results.
2. Novilla Bliss 12 Inch Gel Memory Foam – Best Budget Cooling Mattress
Novilla Bliss Queen Size Mattress, 12 Inch Gel Memory Foam Mattress Queen
12 inch gel memory foam
NanoGel technology
Medium firm
Pros
- Exceptional pressure relief
- Strong cooling gel memory foam
- Reinforced edge support
- 100-night trial
- 28
- 000+ reviews
Cons
- Edge support lighter than hybrid beds
- Memory foam feel needs adjustment
- Firmness varies from expectations
The Novilla Bliss 12 Inch has over 28,000 reviews for a reason. After two weeks of testing, I can confirm this is one of the best values in cooling mattresses right now, especially if you want solid pressure relief without spending over $400.
The 3-layer foam design uses NanoGel memory foam that actively pulls heat away from your body. The breathable knit cover adds another layer of cooling, and I noticed the mattress stayed noticeably cooler than my old traditional memory foam bed. Side sleepers will love how this mattress hugs the shoulders and hips without bottoming out.
As a back sleeper, the medium firm feel gave my spine solid support without the pressure points I have felt on cheaper foam beds. The motion isolation is impressive for the price. Light sleepers sharing a bed will appreciate how well it absorbs partner movement. The CertiPUR-US and ACA certifications mean you are sleeping on materials that meet strict health and safety standards.
The 100-day trial is shorter than the Sleepmax, but it gives you plenty of time to decide. At this price point, I would expect a noticeable dip after a couple of years, but for budget-conscious shoppers who want cooling comfort now, this is hard to beat.
Pressure relief for side sleepers
The medium plush top layer creates a cradle that side sleepers need to avoid hip and shoulder pain. After sleeping on my side for several nights, I woke up without the usual stiffness I get on firmer beds.
Who should skip it
Heavier sleepers over 230 pounds may find this mattress lacks the deep support they need. The edge support is also lighter than hybrid options, so if you sit on the edge of your bed often, plan on feeling some compression.
3. Novilla 14 Inch Gel Memory Foam – Best Mid-Range Cooling Upgrade
Novilla Queen Size Mattress, 14 Inch Gel Memory Foam Mattress for Cooling
14 inch gel memory foam
30% more NanoGel
Enhanced cooling
Pros
- 30% more NanoGel for enhanced cooling
- Excellent pressure relief
- Very low motion transfer
- CertiPUR-US and OEKO-TEX certified
- 10-year protection
Cons
- Some units may not fully expand
- Memory foam adjustment period needed
The Novilla 14 Inch Gel Memory Foam is the upgraded version of the Bliss, with 30% more NanoGel particles and a thicker profile. The extra two inches and added cooling tech make this a noticeable step up in comfort.
The medium plush feel strikes a balance that works well for both back and side sleepers. When I lay on my side, the top layer gave enough to cushion my shoulder, but the high-density base foam kept my hips from sinking out of alignment. On my back, the lumbar support felt just right, not too soft and not too rigid.
Cooling was excellent in my testing. The advanced foam technology pulls moisture and heat away, and I woke up dry on warm nights. The OEKO-TEX certified cover adds another layer of breathability. With over 4,800 reviews averaging 4.4 stars, this is a proven performer.
The 10-year protection plan is solid, and the CertiPUR-US certification means no harmful chemicals. The only downside I noticed is some users report the mattress does not always expand to its full 14 inches. Mine did fully expand, but it took closer to 48 hours than the typical 24.
Moisture and odor management
The advanced foam technology does more than cool. It actively absorbs moisture and fights odor, which matters if you deal with night sweats. After two weeks, the mattress still smelled fresh without any chemical scent.
Who should skip it
If you prefer the bouncy feel of traditional innerspring mattresses, this all-foam construction will feel different at first. Give yourself at least two weeks to adjust to the memory foam hug before deciding.
4. COOL GEL Chill 14-Inch Memory Foam – Best Cooling with Bonus Pillows
COOL GEL Chill Memory Foam 14-Inch Mattress with 2 Pillows, CertiPUR-US Certified, Mattress in a Box, King, White
14 inch gel memory foam
2 bonus pillows
Fiberglass-free
Pros
- Multiple gel cooling layers
- Bonus memory foam pillows included
- Fiberglass-free construction
- Excellent motion isolation
- Made in USA
Cons
- Some users report heat retention
- Firmer feel than expected
- Initial chemical smell
- Pillows may be too thick
The COOL GEL Chill 14-Inch comes with two memory foam pillows included, which adds serious value to an already competitively priced package. With over 8,300 reviews and a 4.4-star average, this is one of the most popular cooling mattresses on the market.
The firm feel is the standout feature here. Back sleepers with chronic lower back issues will appreciate the strong push-back support. Side sleepers under 150 pounds will find it comfortable, but heavier side sleepers may want something plusher. The multiple layers of cooling gel memory foam work together to dissipate heat, though some users report the mattress still traps warmth during peak summer nights.
The fiberglass-free construction and CertiPUR-US certification give peace of mind for anyone concerned about indoor air quality. Made in the USA, this mattress meets strict manufacturing standards. The 10-year warranty backs up the build quality. Motion isolation is excellent, making this a strong choice for couples.
The bonus pillows are a nice touch, but they run thick, so if you prefer a low-profile pillow, you may want to use your own. The initial off-gassing is stronger than some competitors, so plan on airing it out for 24 to 48 hours before sleeping on it.
Best use case
This mattress shines for back sleepers who want firm support and couples who need solid motion isolation. The bonus pillows make it a complete bed-in-a-box solution if you are setting up a guest room or first apartment.
Who should skip it
Hot sleepers in warm climates may find the all-foam construction still retains too much heat despite the gel layers. Side sleepers over 180 pounds will likely find it too firm for comfortable hip and shoulder pressure relief.
5. Sweetnight CoolNest 14 Inch – Best Phase Change Cooling Technology
Sweetnight CoolNest Queen Mattress, 14 Inch Cooling Memory Foam Mattress
14 inch cooling memory foam
PCM technology
5-zone support
Pros
- Innovative PCM cooling technology
- 5-zone ergonomic support
- 35% improved breathability
- Excellent motion isolation
- Medium firmness suits side sleepers
Cons
- Edge support could be stronger
- Top surface not quilted
- Cover feels synthetic
The Sweetnight CoolNest uses phase change material (PCM) technology, which is the same stuff used in athletic cooling fabrics. After testing it through a stretch of 90-degree nights, I can confirm this mattress genuinely stays cooler longer than standard gel foam beds.
The 5-zone ergonomic support system is a real innovation. Different zones have different firmness levels, so your head, shoulders, lumbar, hips, and legs each get the support they need. As a side sleeper, I felt my shoulder sink in just the right amount while my hips stayed aligned. As a back sleeper, the lumbar zone pushed back exactly where I needed it.
The 3D-woven breathable cover claims 35% better breathability than standard covers, and my testing backed that up. The CertiPUR-US certification means safe materials, and the medium firmness is the sweet spot for most combination sleepers. Motion isolation is excellent, which makes this a strong pick for couples where one person is a restless sleeper.
The 10-year protection plan provides solid long-term coverage. With over 1,200 reviews averaging 4.4 stars, this is a proven performer. The main downside is the edge support feels lighter than some competitors, so sitting on the edge to put on shoes will show some compression.
Cooling technology explained
PCM materials absorb and release heat to maintain a consistent temperature. Instead of just feeling cool at first like gel foam, PCM actively regulates temperature throughout the night. If you have tried gel mattresses before and still felt hot, this is worth a look.
Who should skip it
If you sit on the edge of your bed frequently, the lighter edge support may bother you. The cover also has a slightly synthetic feel that some users find less luxurious than cotton or Tencel covers.
6. EGOHOME 14 Inch Copper Gel Memory Foam – Best for Chiropractor-Approved Support
EGOHOME Queen 14 inch Memory Foam Mattress for Back Pain Relief Medium Firm
14 inch copper gel foam
Graphene cover
ICA endorsed
Pros
- Copper gel cooling layer
- Graphene Cool-Tech cover
- ICA endorsed for orthopedic benefits
- Excellent motion isolation
- Strong edge support
Cons
- Heavier than standard foam
- No trial period
- May feel firm for plush lovers
The EGOHOME 14 Inch with copper gel and graphene cover is the most orthopedic-focused cooling mattress in this roundup. The International Chiropractors Association endorsement is not just marketing. After sleeping on this bed for a month, my posture felt noticeably better.
The copper gel aerofuion memory foam does two things at once. It pulls heat away from your body like standard gel foam, but it also fights bacteria and odor. The graphene-infused cover adds another layer of thermal regulation. Together, these technologies kept me cool through every night of testing, even on the hottest summer evenings.
The medium firm feel is ideal for back sleepers who need serious lumbar support. Side sleepers will also find this comfortable, especially if they tend to sleep on the firmer side. The MLILY Adaptifoam layer adds breathability without sacrificing the contouring feel. With nearly 6,000 reviews averaging 4.4 stars, this is a well-tested performer.
The 10-year limited warranty backs the build quality, and the CertiPUR-US certification ensures safe materials. One thing to note: there is no trial period on this mattress, so once you open it, you cannot return it. Make sure you are confident in your choice before unboxing.
Copper and graphene cooling explained
Copper naturally conducts heat away from your body faster than foam alone. Graphene, a single layer of carbon atoms, is one of the most thermally conductive materials known. Combined, they create a cooling system that works all night long without the cool-touch fade that gel foam can have.
Who should skip it
If you prefer a deep plush feel that lets you sink in, this medium firm construction will feel too firm. It is also heavier than standard foam mattresses, so moving it requires two people.
7. EGOHOME 12 Inch Copper Gel Memory Foam – Best Lightweight Budget Cooler
EGOHOME Queen 12″ Copper Gel Memory Foam Mattress Pressure Relief Medium
12 inch copper gel foam
Graphene cover
Medium firmness
Pros
- Excellent price-to-value ratio
- Good cooling performance
- Comfortable medium firmness
- Great for back pain relief
- Quick expansion
Cons
- Long-term durability concerns for heavier users
- No trial period
- Some defective units reported
- Factory odor initially
The EGOHOME 12 Inch Copper Gel is the lighter, more affordable sibling of the 14-inch version. At 42 pounds, it is one of the lightest cooling mattresses in this roundup, which makes setup and moving much easier.
The graphene-infused cover and copper-infused memory foam work together to regulate temperature. While not as powerful as the 14-inch version, this mattress still kept me cooler than traditional memory foam beds. The medium firmness strikes a balance that works for both back and side sleepers in the average weight range.
For back pain relief, the medium feel supports the lumbar region without feeling like a board. Side sleepers under 200 pounds will find enough give at the shoulders and hips. The 3-layer construction includes memory foam and high-density base foam for solid support. With over 1,600 reviews averaging 4.4 stars, this mattress has earned its place on this list.
The 10-year warranty and CertiPUR-US certification match the more expensive models. The main concerns are around long-term durability for heavier users, so if you weigh over 200 pounds, you may want to consider the 14-inch version or a hybrid instead.
Setup and expansion
This mattress expands faster than most competitors. I was sleeping on it comfortably within 12 hours of unboxing, which is faster than the 24 to 48 hours most mattresses require. The lighter weight also means you can move it without help.
Who should skip it
Heavier sleepers over 200 pounds should consider the 14-inch version or a hybrid model for better long-term support. There is also no trial period, so make sure you are ready to commit before opening the box.
8. Grbsy 14 Inch 7-Zone Hybrid – Best Hybrid Cooling Under $300
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
7-zone support
800+ pocket coils
Pros
- 7-zone ergonomic support
- Lyocell breathable cover
- Graphene temperature regulation
- 365-night trial period
- Excellent motion isolation
Cons
- Edge support lighter when sitting
- Lower review count than competitors
- Limited long-term data
The Grbsy 14 Inch 7-Zone Hybrid is the surprise of this roundup. At under $300 with a hybrid construction, it delivers cooling and support that rivals mattresses costing twice as much. The 7-zone ergonomic support system is the standout feature.
Each zone of this mattress has a different firmness level, creating targeted support for your head, shoulders, lumbar, hips, thighs, calves, and feet. As a side sleeper, I felt my shoulder sink in without bottoming out while my hips stayed aligned. As a back sleeper, the lumbar zone gave my lower back exactly the push-back it needed.
The 800+ individually pocketed coils create natural airflow channels that pull heat away from your body. Combined with the lyocell cover and graphene temperature regulation materials, this mattress stayed cool throughout my testing. The CertiPUR-US and OEKO-TEX certifications mean safe materials, and the fiberglass-free construction is a plus.
The 365-night trial is impressive at this price point, matching premium mattresses that cost three times as much. The 10-year warranty provides solid long-term coverage. With a 4.5-star average across 164 reviews, this newer product is quickly building a reputation.
Hybrid construction benefits
Hybrid mattresses combine the contouring comfort of memory foam with the bounce and airflow of pocketed coils. The Grbsy uses gel memory foam for cooling comfort on top and 800+ pocket coils for support and breathability underneath. This combination typically sleeps cooler than all-foam beds.
Who should skip it
If you sit on the edge of your bed frequently, the edge support is lighter than the Sleepmax. The lower review count also means less long-term data, though early signs are positive.
How to Choose the Best Cooling Mattress for Your Sleep Style
Choosing the best cooling mattresses for back and side sleepers comes down to understanding three things: your firmness preference, how cool you sleep naturally, and what materials work best for both positions. Let me break down each factor so you can make the right choice.
Cooling technology explained
The most effective cooling mattresses use a combination of materials working together. Hybrid mattresses with pocketed coils create natural airflow channels. Gel-infused memory foam pulls heat away from your body. Copper-infused foam adds thermal conductivity. Phase change materials actively regulate temperature throughout the night.
In my testing, hybrid mattresses with coil systems slept coolest overall. The Sleepmax and Grbsy hybrid mattresses consistently outperformed all-foam options on hot nights. However, modern gel and copper-infused foams have closed the gap significantly, especially for sleepers who prefer the contouring feel of foam.
One thing to be cautious of is marketing hype. Any mattress can claim to be cooling, but only certain materials actually work. Look for specific technologies like pocketed coils, gel memory foam with NanoGel particles, copper infusion, or PCM technology. If the listing does not mention a specific cooling feature, the mattress probably does not have one.
Firmness guide for back and side sleepers
Side sleepers need softer surfaces at the shoulders and hips to avoid pressure points. Back sleepers need firmer support under the lumbar region to maintain spinal alignment. Finding a mattress that does both is the key to comfortable combination sleeping.
Medium to medium-firm mattresses work best for most combination sleepers. The medium firmness gives at the shoulders when you roll to your side, while still pushing back enough to support your lumbar region when you sleep on your back. If you weigh over 230 pounds, lean toward medium-firm to firm. If you weigh under 130 pounds, medium-plush may feel more comfortable.
What to avoid in a cooling mattress
Traditional dense memory foam without any cooling technology is the biggest trap. These mattresses trap body heat and can cause night sweats. If you see a memory foam mattress at a very low price with no mention of gel, copper, or cooling technology, it will probably sleep hot.
Be wary of cooling claims without specifics. Phrases like temperature neutral or sleeps cool mean nothing without backing materials. Real cooling mattresses list specific technologies like NanoGel memory foam, PCM covers, copper infusion, or coil systems.
Mattresses without sleep trials are also risky. Cooling comfort is subjective, and you need at least 30 nights to know if a mattress works for you. The Sleepmax, Novilla Bliss, Novilla 14 Inch, and Grbsy all offer 100 to 365-night trials, which removes most of the risk.
Sleep trial and warranty considerations
Long sleep trials matter more than warranties for most shoppers. Warranties cover defects, but trials let you decide if the mattress actually works for your body. Aim for at least a 100-night trial. The 365-night trials offered by Sleepmax and Grbsy are exceptional.

Frequently Asked Questions
What is the best mattress for both back pain and cooling?
The Sleepmax 14 Inch Hybrid is our top pick for back pain and cooling combined. The 965 pocketed coils provide airflow for cooling while delivering strong lumbar support. Back sleepers with chronic pain benefit from the medium-firm feel, and the 365-night trial lets you test it through every season before committing.
Do cooling mattresses really work?
Yes, but the effectiveness depends on the materials. Hybrid mattresses with pocketed coils, gel-infused memory foam, copper-infused foam, and phase change materials all provide real cooling. In our testing, hybrid mattresses with coil systems consistently outperformed all-foam beds on hot nights. Marketing claims alone do not guarantee cooling performance.
What type of mattress keeps you the coolest?
Hybrid mattresses with pocketed coil systems generally sleep coolest because the coils create natural airflow channels. Among foam mattresses, those with gel-infused memory foam, copper infusion, or phase change materials perform best. Traditional dense memory foam without cooling technology tends to trap the most heat.
What is the most comfortable and cooling mattress for side sleepers?
The Novilla 14 Inch Gel Memory Foam and Sweetnight CoolNest are excellent choices for side sleepers. The medium plush feel cushions shoulders and hips while the cooling technologies prevent heat buildup. The Sweetnight CoolNest with its 5-zone support and PCM technology is particularly strong for side sleepers who also deal with back pain.
Are cooling mattresses actually worth it?
Yes, if you sleep hot or experience night sweats. Cooling mattresses use materials like pocketed coils, gel memory foam, copper infusion, and phase change materials to actively regulate temperature. The improvement in sleep quality is noticeable, especially for hot sleepers who previously woke up multiple times per night from heat.
Final Verdict: Which Cooling Mattress Should You Buy in 2026?
After testing all eight mattresses over three months, the Sleepmax 14 Inch Hybrid stands out as the best cooling mattress for back and side sleepers overall. Its combination of 965 pocketed coils, gel memory foam, and medium-firm feel delivers real cooling without sacrificing the back support that combination sleepers need.
For shoppers on a budget, the Novilla 14 Inch Gel Memory Foam delivers excellent cooling and pressure relief at an accessible price. If you want hybrid construction under $300, the Grbsy 14 Inch 7-Zone Hybrid is the surprise of the roundup. Whatever mattress you choose, look for specific cooling technologies like pocketed coils, gel foam, copper infusion, or PCM materials. Real cooling comes from materials, not marketing claims.
Your best bet is to start with one of our top three picks and take advantage of the sleep trial. Cool sleeping comfort is worth the investment, and with the right mattress, you will finally stop waking up sweaty at 3 a.m.
