Why Do Mattresses Get Hot? The Science of Heat Retention

Before diving into product recommendations, it helps to understand why certain mattresses sleep hotter than others. The answer comes down to material science, specifically the cellular structure of the foams used in your mattress.

Closed-Cell vs. Open-Cell Foam

Traditional memory foam (viscoelastic polyurethane) uses a closed-cell structure. Each cell is sealed off from its neighbours, creating millions of tiny insulating pockets. While this gives memory foam its signature contouring feel, it also traps body heat. Your body generates approximately 80-100 watts of heat during sleep, and closed-cell foam acts like an insulating blanket, reflecting that heat back toward you.

Open-cell foams, by contrast, have interconnected cell walls that allow air to flow through the material. This is one reason why natural latex (which is inherently open-cell) sleeps significantly cooler than memory foam. The porous structure allows heat to escape rather than accumulate.

The Gel Foam Limitation

Gel-infused memory foam was marketed as the solution to hot sleeping in the early 2010s. And while gel beads do absorb heat initially (acting as a thermal sink), they have a significant limitation: gel saturates after 2-3 hours. Once the gel beads reach thermal equilibrium with your body heat, they stop absorbing and can actually become a heat source. This is why many sleepers report feeling cool when they first lie down on a gel mattress, only to wake up hot several hours later.

Graphite Foam: The Superior Conductor

Graphite-infused foam represents a meaningful advancement over gel alone. Graphite is a natural thermal conductor (the same material used in heat sinks for electronics). Rather than simply absorbing heat like gel, graphite continuously conducts heat away from your body, transferring it toward the edges and base of the mattress where it can dissipate. Studies in thermal engineering have shown that graphite composites can dissipate heat up to 3 times faster than standard gel-infused foams.

Natural Latex: Nature's Cooling Material

Natural latex, harvested from the sap of the Hevea brasiliensis rubber tree, has an inherently porous open-cell structure. Unlike synthetic foams where open cells must be engineered, latex develops its breathable cellular structure naturally during the vulcanization process. This gives natural latex a cooling advantage that does not degrade over time, unlike gel which can break down. Research shows that latex sleeps 3-5 degrees cooler than equivalent memory foam.

Coil Systems and Airflow

The support core of a mattress plays a crucial (and often overlooked) role in temperature regulation. Pocket coil systems create open channels throughout the lower half of the mattress, allowing air to circulate freely. This ventilation effect draws heat away from the comfort layers above. All-foam mattresses, by contrast, have no such airflow channels, which is one reason why even "cooling" all-foam beds tend to sleep warmer than hybrids.

Phase-Change Materials (PCMs)

Phase-change materials are the newest frontier in mattress cooling technology. PCMs are microcapsules embedded in fabric or foam that absorb heat energy as they transition from solid to liquid state (typically activating between 28-32 degrees Celsius). When your body temperature drops, they release that stored energy. The result is a more stable, consistent sleeping temperature throughout the night.

The Optimal Sleep Temperature

Sleep researchers broadly agree that the optimal bedroom temperature for sleep is between 15.6 and 19.4 degrees Celsius (60-67 degrees Fahrenheit). However, the micro-climate between your body and mattress surface often exceeds 30 degrees Celsius, regardless of room temperature. This is why mattress material selection matters even if you keep your bedroom cool.

Cooling Technology Comparison: What Actually Works?

Best Cooling Mattresses in Canada for 2026: Our Top Picks

We have tested and evaluated dozens of mattresses for their cooling performance. Below are our top recommendations, starting with in-store options you can try at Mattress Miracle in Brantford, Ontario, followed by popular online brands for comparison.

1. Esha Cooling Gel & Latex Hybrid (Our #1 Cooling Pick)

Type: Hybrid (Latex + Gel Foam + Pocket Coils)
Price: Contact for pricing
Cooling Rating: 9.5/10
Available at: Mattress Miracle, Brantford

The Esha Cooling Gel & Latex Hybrid is the most effective cooling mattress we carry, and it earned our top recommendation for 2026. What makes it exceptional is its layered cooling approach, combining three distinct temperature-regulation technologies in a single mattress.

The comfort layer uses natural latex, which has an inherently breathable open-cell structure. Unlike gel foam that saturates, latex's cooling properties are permanent and will not degrade over time. Above the latex, a layer of gel-infused foam provides initial heat absorption during the critical first hours of sleep when your body is still thermoregulating. Beneath it all, a pocket coil support system creates airflow channels that ventilate the entire mattress from below.

This three-layer system means you get immediate cooling (gel), sustained cooling (latex), and continuous ventilation (coils). In our testing, the Esha maintained a noticeably cooler surface temperature throughout a full 8-hour sleep period compared to any all-foam mattress we tested.

Best for: Hot sleepers who want premium cooling without compromising on pressure relief. The natural latex provides excellent contouring while maintaining superior breathability.

2. Natural Life Sleep-In Hybrid

Type: Hybrid (Graphite Gel Foam + Pocket Coils)
Price: $1,889 (Queen)
Cooling Rating: 9/10
Firmness: 6.5/10 (Medium-Firm)
Available at: Mattress Miracle, Brantford

The Natural Life Sleep-In Hybrid represents the latest advancement in foam-based cooling technology. Its standout feature is graphite gel cooling foam, which dissipates heat up to 3 times faster than standard gel-infused foams. While gel absorbs heat (and eventually saturates), graphite conducts heat away continuously, similar to the heat sinks used in computer processors.

The support system features 1,166 tri-zone pocket coils, providing not only excellent back support but also substantial airflow beneath the comfort layers. The tri-zone design means firmer support in the lumbar region and softer contouring at the shoulders and hips, all while maintaining open air channels throughout.

This mattress is CertiPUR-US certified (low VOC emissions, no harmful chemicals) and proudly made in Canada. At a 6.5/10 firmness, it sits in the sweet spot that works for the majority of sleep positions.

Best for: Sleepers who prefer foam contouring but want best-in-class heat dissipation. The graphite technology delivers sustained cooling that outlasts traditional gel foams.

3. Elena by Sleep In

Type: Hybrid (Natural Latex + Gel Foam + Pocket Coils)
Price: $1,100 (Queen)
Cooling Rating: 8.5/10
Available at: Mattress Miracle, Brantford

The Elena by Sleep In offers an outstanding combination of cooling performance and value. Like the Esha, it combines natural latex with gel foam and pocket coils. The natural latex comfort layer sleeps 3-5 degrees cooler than equivalent memory foam, and its open-cell structure provides breathability that will not diminish over years of use.

At $1,100 for a Queen, the Elena sits at an attractive price point for a hybrid mattress with natural latex. You are getting materials and cooling performance that rival mattresses costing $1,500-$2,000 from online brands. The key difference is that you can actually try the Elena in our showroom before buying, something you cannot do with most online mattress brands.

Best for: Value-conscious hot sleepers who want natural latex cooling without the premium price tag. An excellent choice for couples where one partner sleeps hot.

4. Dream Catcher Flippable

Type: Innerspring (Flippable)
Price: $795 (Queen)
Cooling Rating: 8/10
Available at: Mattress Miracle, Brantford

The Dream Catcher Flippable takes a fundamentally different approach to cooling: rather than relying on advanced materials, it uses traditional innerspring engineering for maximum natural airflow. The open coil system allows air to flow freely throughout the entire mattress, creating a naturally ventilated sleep surface.

As a flippable mattress, the Dream Catcher offers two comfort levels in one purchase, and flipping it regularly extends its lifespan to 15+ years. This durability makes the $795 price point exceptionally economical on a per-year basis.

While the Dream Catcher does not have the advanced foam technologies of the Esha or Natural Life, its innerspring construction means it will never develop the heat retention issues associated with foam mattresses. For sleepers who run hot and prefer a more traditional mattress feel, the Dream Catcher is an excellent choice.

Best for: Budget-conscious hot sleepers, those who prefer a traditional innerspring feel, and anyone who values long-term durability. Also ideal for guest rooms and rental properties.

Online Brands Compared: How Do They Stack Up for Cooling?

Online mattress brands are popular in Canada thanks to convenient delivery and extended trial periods. However, when it comes to cooling performance, there are important trade-offs to understand. Here is how the most popular online options compare.

Endy Original

Type: All-Foam
Price: $895 (Queen)
Cooling Rating: 5.5/10
Owned by: Fairfax Financial / Sleep Country Canada

The Endy Mattress uses an open-cell foam construction (which allows air to pass through instead of trapping it) and has a layer of Endy Comfort Cooling Foam infused with cooling gel. These features work together for that cool to the touch feeling when you first get into bed while actively drawing heat away from the body throughout the night. For hot sleepers who want the flexibility of a long trial, Endy's 365-night return window makes it a lower-risk choice.

For comparison: hybrid mattresses with pocket coils still have a structural advantage in airflow because the coil layer creates dedicated channels for heat to escape. If you sleep exceptionally hot or share a bed with another warm sleeper, a hybrid is worth testing alongside the Endy.

Douglas Original

Type: All-Foam
Price: $799 (Queen)
Cooling Rating: 6/10
Owned by: GoodMorning.com (independent)

The Douglas Original features what it calls ecoLight cooling gel foam, which is a lighter-density gel foam that allows somewhat better airflow than the dense foams used in earlier bed-in-a-box mattresses. Douglas does deliver a slightly cooler sleep surface than the Endy in our assessment.

However, like the Endy, the Douglas is an all-foam mattress. Without coils, the fundamental limitation on airflow remains. Douglas is one of the more honestly positioned online brands (it is genuinely independent, operated by GoodMorning.com), and its $799 price is competitive. But for hot sleepers specifically, a hybrid with coils will always outperform an all-foam design.

Silk & Snow Hybrid

Type: Hybrid (Foam + Pocket Coils)
Price: $1,150 (Queen)
Cooling Rating: 7/10
Owned by: Fairfax Financial / Sleep Country Canada

The Silk & Snow Hybrid is a step up for hot sleepers thanks to its pocket coil system, which provides the airflow channels missing from all-foam designs. The coil base allows heat to dissipate downward and outward, rather than building up in the comfort layers.

However, the comfort layers above the coils are standard memory foam (with some gel infusion), not natural latex or graphite. This means the top layers where you actually make contact with the mattress still rely on gel for cooling, with its associated saturation limitations.

At $1,150, the Silk & Snow Hybrid costs the same as the Elena by Sleep In ($1,100), which includes natural latex for superior sustained cooling. The Elena also has the advantage of being testable in our showroom.

Note: Like Endy, Silk & Snow is now owned by Fairfax Financial through Sleep Country Canada. Read our full Silk & Snow review here.

Purple Mattress

Type: Hybrid (Hyper-Elastic Polymer Grid + Pocket Coils)
Price: $1,800+ (Queen, varies by model)
Cooling Rating: 8/10

Purple's unique hyper-elastic polymer grid is genuinely innovative for cooling. The grid structure creates an open channel design that allows air to flow directly through the comfort layer, something no foam (no matter how advanced) can replicate. Combined with pocket coils in their hybrid models, Purple mattresses deliver strong cooling performance.

The trade-off is price. Purple mattresses are among the most expensive in the Canadian market, and the unique grid feel is polarizing: you either love it or find it unusual. Purple also has limited availability for in-person testing in Canada, making it a risky purchase for many consumers.

Buying Guide: How to Choose a Cooling Mattress in Canada

With so many options on the market, here are the key factors to prioritize when shopping for a cooling mattress:

1. Prioritize Hybrid Construction

If you sleep hot, an all-foam mattress (no matter how many cooling gels it contains) will always be at a disadvantage compared to a hybrid with coils. The pocket coil base provides structural airflow that foam simply cannot replicate. Every mattress in our top 4 includes a coil system for this exact reason.

2. Look Beyond "Gel-Infused"

Gel infusion is now the minimum standard for cooling, and it is not enough on its own. Look for mattresses that combine gel with other technologies: natural latex, graphite, phase-change materials, or enhanced airflow design. Single-technology cooling is almost always inferior to multi-layer approaches.

3. Consider Natural Latex

If you want cooling that never degrades, natural latex is your best option. Its open-cell structure is inherent to the material, not an added treatment that can break down. Latex is also naturally hypoallergenic and resistant to dust mites, mold, and bacteria.

4. Test Before You Buy

Cooling is highly subjective. What feels cool to one person may feel warm to another, depending on body composition, metabolism, sleep position, and bedding choices. This is why we strongly recommend testing mattresses in person before purchasing. Online trial periods are useful, but the hassle of returning a mattress (boxing it back up, scheduling pickup) means many people keep mattresses they are not fully satisfied with.

5. Do Not Forget Your Bedding

Even the best cooling mattress can be undermined by the wrong bedding. Pair your mattress with breathable sheets (look for percale cotton, French linen, or bamboo lyocell), a ventilated pillow, and an appropriate duvet weight for the season. A cooling mattress with a thick polyester duvet on top is working against itself.

6. Check the Ownership

Many "independent" online mattress brands in Canada are now owned by the same parent companies. Both Endy and Silk & Snow are owned by Fairfax Financial Holdings through Sleep Country Canada. This does not necessarily make them bad products, but it is worth knowing that the "plucky startup" branding may not reflect the current corporate reality. Mattress Miracle has been family-owned since 1987 and remains genuinely independent.

Frequently Asked Questions About Cooling Mattresses in Canada

What is the best cooling mattress in Canada for 2026?

The Esha Cooling Gel & Latex Hybrid is our top pick for the best cooling mattress in Canada for 2026. It combines three cooling technologies (natural latex, gel-infused foam, and pocket coil airflow) for sustained temperature regulation throughout the night. You can test it at Mattress Miracle in Brantford, Ontario.

Do cooling mattresses actually work?

Yes, but effectiveness varies dramatically by technology. Mattresses with natural latex, graphite foam, or pocket coil airflow provide meaningful, sustained cooling. Basic gel-infused foam offers initial cooling that diminishes after 2-3 hours as the gel reaches thermal equilibrium. The most effective cooling mattresses combine multiple technologies rather than relying on a single approach.

Why does my memory foam mattress sleep so hot?

Traditional memory foam uses a closed-cell structure where each cell is sealed off, creating millions of tiny insulating pockets. Your body generates 80-100 watts of heat during sleep, and closed-cell foam traps this heat rather than allowing it to dissipate. All-foam mattresses compound this issue by lacking the airflow channels that coil-based mattresses provide.

Is gel foam or latex better for cooling?

Natural latex is superior for sustained cooling. Gel foam absorbs heat initially but saturates after 2-3 hours, at which point its cooling benefit diminishes. Natural latex has an inherently open-cell, porous structure that provides continuous breathability and sleeps 3-5 degrees cooler than memory foam. Latex's cooling properties are permanent and do not degrade over time.

What is graphite foam and how does it cool?

Graphite-infused foam contains graphite particles (a natural thermal conductor) distributed throughout the foam. Unlike gel, which passively absorbs heat, graphite actively conducts heat away from your body on a continuous basis. It works similarly to the heat sinks in electronic devices. Graphite foam can dissipate heat up to 3 times faster than standard gel foam and does not saturate.

Are online mattresses good for hot sleepers?

It depends on the specific mattress. Most popular online mattresses in Canada (Endy, Douglas) are all-foam designs that rely solely on gel infusion for cooling. These will always sleep warmer than hybrid mattresses with coils. If buying online, look specifically for hybrid models that include pocket coils. Better yet, visit a showroom like Mattress Miracle to test cooling mattresses in person before committing.

What bedroom temperature is best for sleep?

Sleep researchers recommend a bedroom temperature between 15.6 and 19.4 degrees Celsius (60-67 degrees Fahrenheit) for optimal sleep quality. However, the micro-climate between your body and mattress surface is typically 8-12 degrees warmer than room temperature, which is why your mattress material matters even if your bedroom is cool. Research by Okamoto-Mizuno & Mizuno (2012) confirms that the thermal environment is one of the most significant factors affecting sleep architecture.

How long do cooling mattresses last?

The longevity of cooling properties depends on the technology. Natural latex's cooling is permanent (inherent to the material's structure). Graphite foam maintains its conductivity for the life of the mattress. Gel-infused foam may see reduced effectiveness after 3-5 years as the gel compound breaks down. Coil-based airflow is permanent since it is structural. The Dream Catcher Flippable, for example, offers 15+ years of natural airflow cooling through its innerspring design.

Is a cooling mattress worth the extra cost?

For hot sleepers, absolutely. Research shows that sleep disruption from heat can increase pain sensitivity by 42% (Krause et al., 2019) and impair REM sleep, which affects memory consolidation and emotional regulation. A cooling mattress that costs $200-$400 more than a basic model can deliver years of better sleep quality. Additionally, the Dream Catcher Flippable at $795 proves that effective cooling does not require a premium price tag.

Can I make my current mattress cooler without replacing it?

Yes, several strategies can help: use a breathable mattress topper (natural latex or gel-infused), switch to percale cotton or bamboo lyocell sheets, use a ventilated pillow, reduce your duvet weight, and keep your bedroom temperature below 19.4 degrees C. However, if your mattress is an all-foam design with significant heat retention, these are partial solutions. A mattress with proper cooling engineering will outperform any add-on accessory.
