Overheating is a common problem among Canadians of all ages. No matter how you sleep, you may be uncomfortable when heat builds up within your mattress. Foam mattresses are especially prone to overheating, but some measures can be taken to reduce heat. Here, we’ve looked through all of our favourite mattresses to bring you those that reduce heat the best. These mattresses vent and isolate heat quickly, leaving you feeling more comfortable when you wake up in the morning.
Testing Cooling Mattresses for Canadians
Our Scoring Process for Cooling Mattresses
When we scored our cooling mattresses, we looked at a range of features that impacted how they performed. We looked at the feel and pressure relief scores across the board, as well as factoring in how our testers felt about the mattress during their practical tests. These scores were combined to create an average consensus on how the mattress worked.
Our Cooling Mattress Tests
Like all mattresses, we tested our cooling mattresses using both practical and simulation tests. To test for heat retention, we used heat mapping technology with values taken over several minutes at a time. We also took tester feedback into account, specifically the feedback from those who sleep extremely hot.
How We Chose Our Cooling Mattresses
We chose our cooling mattresses based on how they performed when we put them to the test. We wanted to recommend mattresses that provided the coolest, most comfortable experience possible. This means we did our best to bring you the coolest mattresses in Canada for all sleepers, even those who slept the hottest.

Editor’s Choice – Octave Mirage
- Temperature Control: 9.3/10
- Motion Isolation: 8.2/10
- Edge Support: 8.6/10
- Pressure Relief: 10/10
- Bounce: 8.2/10
- Eco: 8.5/10
- Response: 8.9/10
- Ease of Movement: 8.6/10
- Policies: 9/10
Highlights
- Outstanding pressure relief, even among its fellow all-foam mattresses
- Great company policies
- Cooling features include copper-infused gel and phase-changing materials
The Octave Mirage is the midline model from Octave’s lineup. This mattress’s cooling and comfort blend makes it a good choice for most Canadians. It shines when it comes to pressure relief. As we’ll see below, this mattress received some of the best scores we’ve seen for pressure relief. Combined with its cooling capabilities, it’s a mattress you shouldn’t pass up. Its affordable price makes it appealing for most Canadians as well.
Octave Mirage Mattress Construction
- CryoFusion Cooling Nanofibre Cover. The breathable cover uses CryoFusion cooling nanofibres to wick away heat and moisture, leaving the surface of the mattress cooler.
- 2.5” CopperGel Memory Foam + PolarMAX. A thicker layer of copper-infused memory foam conducts heat away from you while phase-changing bands in the middle of the mattress help balance extreme temperatures so you don’t overheat.
- 1.5” Aerated Latex Foam. The middle of the mattress features a layer of latex foam with heavy air ventilation. Cool air cycles up through the mattress, creating a breathable surface that doesn’t allow heat to build up.
- 2” ecoLuxe Cooling Gel Foam. ecoLuxe is a cooling foam that provides excellent pressure relief. This layer allows your joints to rest without discomfort, no matter which position you sleep in.
- 2” Premium Elastex Foam. Elastex is a latex alternative that mimics the properties of natural latex. This means that it’s comfortable, responsive, and bouncy. This layer helps with motion isolation and ease of movement.
- 6” Multi-Zone Support Foam with Air Channels. Air channels within the zoned foam base help maintain airflow, while the high-density foam stops motion and keeps sagging away.
Octave Mirage Mattress Performance Scores
Temperature Control – 9.3/10
Perforated latex, phase-changing materials, and cooling foams work together to reduce higher temperatures throughout the core of the mattress. Temperature dissipated quickly, and the materials (particularly the phase-changing materials) worked to maintain a consistent cooler temperature. We had no complaints from our testers, except those who slept extremely hot consistently.
Motion Isolation – 8.2/10
If there is one area that performs a little worse than what we like to see, it is motion isolation. This mattress doesn’t isolate motion well, and our testers were able to feel movements from the other side of the bed. Simulation tests and practical tests returned similar results. We can’t recommend this mattress to those who need total motion isolation.
Pressure Relief- 10/10
However, this mattress is extremely comfortable when it comes to pressure relief. In all of our testing, this mattress received the best pressure relief results out of most of the mattresses on the Canadian market. It uses soft, responsive layers that help cushion your deepest pressure points. Our testers reported that this mattress never returned any pressure, even in areas where they pressed deeply into the mattress.
Ease of Movement – 8.6/10
Pressure relief comes at a cost, and for this mattress, it’s ease of movement. While the results of this test weren’t terrible, they weren’t the best we’ve seen. You won’t feel any significant resistance while trying to move around, but it won’t be as easy as some of the other mattresses on the Canadian market.
Who is the Octave Mirage For?
- Side sleepers. The outstanding pressure relief makes this mattress a good choice for side sleepers, particularly those who develop pressure points easily.
- Hotter sleepers. Of course, this mattress is at the top of our list of cooling mattresses for a reason. The multiple temperature control features work together to create a mattress that works for even the hottest sleepers.
- Those who move around a lot. Even though this mattress has a lot of pressure relief, you won’t feel like you are sinking too far into the mattress. You won’t have to fight with it when you need to turn over.
Who Should Avoid the Octave Mirage?
- Couples and co-sleepers. This mattress doesn’t isolate motion well, which may be a problem for those who wake up when their partner tosses and turns. If this is a problem for you, you may want to find a different mattress.

Highlights
- Excellent motion isolation for those who need feedback from their mattress
- One of the longest warranties on the Canadian mattress market
- Performs well when it comes to response, ease of movement, motion isolation, and edge support.
The Douglas Alpine surprised us. After rounds of testing, it offered surprisingly strong performance in most areas, including response, ease of movement, and motion isolation. It has strong edge support for an all-foam mattress. The only area where it came up short was bounce. For some, this won’t be a problem. It’s also a little thin for heavier side sleepers, but it performs well for most average and lightweight side sleepers.
Douglas Alpine Mattress Construction
- Douglas CoolSense Cover. The removable cover is machine-washable. It is made with a blend of sustainable Infinitex fibres and a cooling weave that maintains breathability even when you sleep hot.
- 2.25” Luxury ecoLight Cooling Gel Foam with Polar Temperature Balancing. The top layer is coated with phase-changing material, which reduces temperature spikes by maintaining a consistent temperature. This layer is made with less carbon input than standard memory foam but maintains the pressure relief usually found in high-density foams.
- 2.25” Premium Elastex Foam. A middle layer of Elastex stops motion in its tracks and helps with pressure relief. This layer is made with a latex alternative that is bouncy and responsive, making it easier to move around on the mattress.
- 6.5” Motion Isolation Support Foam. The bottom of the mattress features a high-density support layer. This layer stops motion in its tracks and helps align your spine for better support.
Douglas Alpine Mattress Performance Scores
Temperature Control – 9.1/10
The two layers at the top of the Douglas Alpine do a lot of work to keep you cool. First, the phase-changing material keeps the mattress at a consistent temperature to help you sleep more comfortably. The layer of cooling gel foam helps isolate heat, and the Elastex foam at the centre doesn’t allow it to build up and become uncomfortable. Testing showed that the mattress maintained its efforts to remove heat, providing a more consistent temperature reduction across several hours of use.
Motion Isolation – 9.8/10
Motion isolation is important, particularly if you are a light sleeper. If you often wake up when your partner tosses and turns, this score will be great news for you. This mattress dampens motion extremely well, so you’ll feel less than ever from the other side of the bed. We performed both types of testing for motion isolation, including practical and simulation tests. Both returned amazing results.
Pressure Relief- 9.1/10
The Douglas Alpine has great pressure relief, particularly for those who don’t sink too far into the mattress. Average and lightweight sleepers will have the best time with this mattress, as the comfort layers are a bit thin for heavier side sleepers. Still, most won’t have any issues at all with the pressure from this mattress. The layers do their best to keep you comfortable, and most of our testers didn’t report any issues.
Ease of Movement – 9.6/10
Even though this all-foam mattress can cradle your body and create better pressure relief, it isn’t hard to move around when you need to. Even after hours of sleeping in one spot, our testers found it extremely easy to turn over and change position. That’s because this mattress offers a surprisingly strong response time. We noted that it moved faster than average to regain its shape.
Who is the Douglas Alpine For?
- Restless couples. If your partner wakes you up by tossing and turning, this mattress is a great help. It isolates motion, trapping it so it doesn’t move to the other side of the mattress and wake you up.
- Active sleepers. Do you move around a lot in your sleep? If you do, you won’t have to fight with this mattress. It’s easy to move around on the surface.
- Canadians who value customer service. As a company, Douglas offers some great policies. You’ll have a full year to test the mattress and 20 years to activate your warranty if something goes wrong.
Who Should Avoid the Douglas Alpine?
- Heavy side sleepers. This mattress is a little on the thinner side when compared to some of the other mattresses on our list. The comfort layers may not offer enough cushion for those who sink deeper into the mattress.

Best All Foam – Casper Snow
- Temperature Control: 9.8/10
- Motion Isolation: 7.2/10
- Edge Support: 9.5/10
- Pressure Relief: 9.1/10
- Bounce: 8.6/10
- Eco: 7/10
- Response: 7.1/10
- Ease of Movement: 8.4/10
- Policies: 8/10
Highlights
- One of the best performers for temperature regulation
- Better edge support than most other all-foam mattresses
- Zoned foams and HeatDelete bands are unique to Casper
The Casper Snow is packed with proprietary and specialty foams to provide the cooling profile that you need from a mattress. This option uses multiple layers of phase-changing materials to reduce heat. You’ll feel virtually no build-up as you rest, making it extremely easy to stay comfortable. With great scores in edge support and pressure relief, this mattress has something for everyone.
Casper Snow Mattress Construction
- Casper Knit Cover. The cover of the Casper Snow mattress is knit with cooling yarn, so it is extremely breathable and refreshing. It also features firmer edges, which boosts edge support.
- Casper Signature Foam with Cooling PCM & AirScape Technology. The top layer of the mattress uses Casper’s signature foam. It is coated with a layer of phase-changing material to maintain a constant temperature, as well as AirScape foam for additional breathability.
- HeatDelete Bands. HeatDelete bands used throughout the mattress help vent away excess heat, reducing the amount of heat you’ll feel at the top of the mattress for up to 12 hours or more.
- Memory Foam with Zoned Support. This layer of high-density foam cradles your body, relieves pressure on your joints, and aligns your spine for a more comfortable sleep experience. The zoned support means it is firmer under your hips and back.
- Flex Coils with Edge Support. The support core of the mattress features flexible pocket coils, which form to your body and help align your spine. This layer also includes an edge support perimeter, which reduces discomfort and bolsters the edges of the mattress.
Casper Snow Mattress Performance Scores
Temperature Control – 9.8/10
Casper’s Snow Mattress tested extremely well when it came to temperature regulation. It isolated heat almost immediately, working to reduce it quickly. All of our tests showed that the mattress maintained a consistently cool temperature throughout the night, even for our hottest sleepers.
Motion Isolation – 7.2/10
The Casper Snow isn’t a great choice for couples and those with restless partners. The motion isolation doesn’t stack up to other all-foam mattresses, which may be due to the dense materials used in the construction. No matter which test results we looked at, we couldn’t find a way that this mattress isolated much motion at all.
Pressure Relief- 9.1/10
Pressure relief is extremely important for side sleepers, but all sleepers can benefit. This pressure relief on this mattress is hardly the worst we’ve seen, but it isn’t the best either. Most Canadians will sleep comfortably on this mattress, even those who sleep on their sides. Our testers didn’t complain too much about any pushback from the mattress, either.
Ease of Movement – 8.4/10
It’s a little harder to move around on this mattress than some of the others we’ve looked at, even those on our list. The foams make it easier to sink in, which can make it more difficult to change positions or turn over in the middle of the night. Our testers said they experienced some resistance, but it wasn’t significant to stop them from changing position in many cases.
Who is the Casper Snow For?
- Extremely hot sleepers. The Casper Snow received one of our best scores during our temperature control testing. If even moderate cooling isn’t good enough for you, this mattress may be able to help.
- Canadians who need lumbar support. The zoned memory foam is firmed through the centre, which can help reduce discomfort at your hips and lower back.
- Edge sleepers. The edges of the mattress maintain the same support that is present in the rest of the mattress. Those who sit and sleep near the edge will be just as comfortable there.
Who Should Avoid the Casper Snow?
- Eco-conscious Canadians. Some of the mattresses on our list are better for the environment than others. Casper doesn’t note any eco-conscious practices or commitments.

To avoid this, you should choose a mattress with better motion isolation properties. The Nectar Premier Copper mattress is one of the best cooling mattresses for motion isolation in Canada.
Best Specialty Foams – Hush Graph Iced
- Temperature Control: 9.6/10
- Motion Isolation: 8.1/10
- Edge Support: 9.4/10
- Pressure Relief: 8.4/10
- Bounce: 8.5/10
- Eco: 8/10
- Response: 9.1/10
- Ease of Movement: 9.4/10
- Policies: 7/10
Highlights
- Specialty and proprietary foams create a unique feel
- Extreme cooling and pressure relief
- Very supportive for those who need it
The Hush Graph-Iced Mattress is one of the best options for you if you appreciate special foam layers. This mattress is made almost entirely with proprietary materials, from cooling foams to phase-changing bands, vented transition layers, and more. This is also the only hybrid option on our list, which adds additional airflow through the centre of the mattress to reduce overheating.
Hush Graph Iced Mattress Construction
- 2” GRAPH-ICED Dual Fusion Layer. The first two layers of the mattress are an extreme gel cooling foam. Both work to relieve pressure points, but they also cool you down to prevent overheating.
- IcedShift Cooling Band. Bands of phase-changing material keep higher temperatures under control. This band in the middle of the mattress reduces heat where it builds up most often.
- 2” AirCross Vented Transition Layer. The transition layer is a vented foam. This firm layer cushions your deepest pressure points, but also makes room for air to escape. The ventilated design may collapse at some points as you get comfortable, which means you get better customized support where you need it most.
- 6” Foam Encased Pocket Coil Support. The coil layer is firm and comfortable. These pocket coils reduce motion more than some of the others on the market. If you aren’t a fan of zoned coils, this may be the mattress for you.
- 2” Ultra Support High Resilient Foam Base. The base of the mattress is a 2” high-density foam that prevents a loss of durability, reducing sagging and helping the mattress maintain its structure.
Hush Graph Iced Mattress Performance Scores
Temperature Control – 9.6/10
Hush’s proprietary cooling foams, ventilated foams, and phase-changing materials fight heat better than most other options on the Canadian market. When the mattress heated up, the temperature was immediately brought back down to a manageable level. It took less time to remove heat than most other mattresses we’ve tested.
Motion Isolation – 8.1/10
Motion isolation can be a problem with this mattress. While it does isolate some motion from the other side of the bed, it isn’t enough to completely eliminate vibrations. Practical tests showed that our testers could feel all but the smallest movements from the other side of the bed. Our simulation tests clocked a lot of movement during our ball drop tests, which means that you’ll feel more than you want to.
Pressure Relief- 8.4/10
Pressure relief is another area where this mattress is less than ideal. Heavier sleepers, especially, should avoid this mattress when possible. The comfort layers aren’t thick enough to stay comfortable in the long term, and pressure points can develop when you press against the mattress. Pressure relief was one of the most common complaints from our testing team.
Ease of Movement – 9.4/10
Despite all of this, it is extremely easy to move around on top of this mattress. You can’t sink very far into it, which means that you won’t feel like you are stuck in the mattress at any point. Our most active testers didn’t report having to fight with the mattress at all. It was simple to move around and easy to get comfortable again because the materials reformed so quickly.
Who is the Hush Graph Iced For?
- Edge sleepers. Sleepers who make a home at the edge of the bed will be surprised to find that it doesn’t sink or collapse under their weight nearly as much as other mattresses might.
- Canadians who are active in their sleep. It’s easy to move around on the surface of this mattress, which may be a relief for Canadians who often change position throughout the night.
- Those who want high-quality materials. All of the materials used within the Hush Graph-Iced Mattress are high-quality and comfortable. These materials are more expensive, but they perform better.
Who Should Avoid the Hush Graph Iced?
- Heavier sleepers. Though this mattress offers firm support, the comfort layers are rather thin when compared to the rest of the mattress. This can lead to uncomfortable pressure points where you make contact with the mattress.

- Policies: 10/10
Highlights
- Great company policies with a long warranty period
- Better motion isolation than most Canadian mattresses
- Quick, responsive materials that promote ease of movement
The Nectar Premier Copper provides something that some of the other mattresses on our list don’t. A lifetime warranty means that you are covered for the lifespan of the mattress, which may range longer than some of the warranties that other mattresses offer. If you have any issues, warranty claims are simple. Aside from that, this mattress offers outstanding pressure relief to those with restless partners, so you can get comfortable knowing that your partner’s movements aren’t going to wake you.
Nectar Premier Copper Mattress Construction
- Dual-Action Cooling Copper Cover. The quilted cover uses cooling fibres and copper to wick heat and sweat away from you. It is soft and comfortable, too.
- 4” Gel Infused Memory Foam. This layer of memory foam is thicker than most mattresses would use. It leads to better pressure relief and improved motion isolation. The gel infusion also moves heat away from you throughout the night.
- 3” Responsive Foam. A layer of transition foam provides the perfect level of response to the mattress. It helps with response and alignment, too.
- 7” Poly Foam Base. The supportive base is made with high-density foam that works well to support the other layers within the mattress. It’s extremely durable and made to provide better sleep.
Nectar Premier Copper Mattress Performance Scores
Temperature Control – 9.1/10
A cooling copper cover and gel-infused foam make this mattress much cooler than some of the other all-foam options in Canada. While it didn’t vent off heat as quickly as some of the other cooling mattresses on our list, our test results showed that it worked to create a comfortable sleeping environment regardless.
Motion Isolation – 10/10
Motion isolation is one of the premier features of this mattress. Something about the dense materials used in the construction of the mattress makes it able to completely neutralize motion. Our testers and testing results returned outstanding reports about how well this mattress stopped motion from reaching you.
Pressure Relief- 9.1/10
The pressure relief within the Nectar Premier Copper mattress isn’t the worst we’ve seen. This mattress does a good job of keeping you comfortable, lifting you out of the mattress, and reducing pressure on your joints. Even our heavier testers who slept on the sides had a much better time with this mattress than any of the others we tried.
Ease of Movement – 9.4/10
The responsive materials within this mattress do a great job of keeping you lifted out of the core. You won’t sink in too far to be comfortable, so it’s easier to move around on the surface. Our testers tried moving around often throughout their testing phases. All of them reported great results and no effort was required to move.
Who is the Nectar Premier Copper Mattress For?
- Couples. When it comes to motion isolation, this mattress knocks it out of the park. You’ll hardly feel a thing from the other side of the bed, even when your partner is moving around quite a lot.
- Active Canadians. It’s extremely easy to move around on the surface of this mattress, making it a great choice for those who change positions often.
- Those who want a longer warranty. The Nectar Premier Copper Mattress features the longest warranty on our list. This lifetime warranty covers a great deal of issues, too.
Who Should Avoid the Nectar Premier Copper Mattress?
- Edge sleepers. The edges of the mattress will fold and sag when you sit on the edge of the bed in the morning. If you need a more supportive edge, this may not be the mattress for you.

Alternative Option
This mattress was a powerhouse for most performance areas, including motion isolation. However, it didn’t do so well when it came to pressure relief. Like most foam mattresses, it suffered from a lack of support as you approached the edges of the mattress. This can make it difficult to get comfortable, so we recommend the stellar edge support in the Hush Graph-Iced Mattress instead.
