Best Mattress for Hot Sleepers
The Octave Vista is our top pick for hot sleepers in Canada. Based on our review of more than 120 mattresses and third-party engineering testing (commissioned by us), the Octave Vista wins in this category because it combines multiple cooling technologies, including a CryoFusion™ cooling cover, CopperGel™ memory foam, and PolarMAX® phase-change material, with strong pressure relief and ergonomic support. These advanced cooling features work together to reduce heat buildup throughout the night without sacrificing comfort or support.
For many people, sleeping hot isn’t just uncomfortable. Excess heat can make it harder to fall asleep, increase nighttime wake-ups, and reduce overall sleep quality. According to Nicola Power (RN), your body naturally cools down before sleep, and when heat becomes trapped around your body, that process can be disrupted.
The good news is that some mattresses are specifically designed to promote airflow and dissipate heat more effectively than others. To identify the best cooling mattresses in Canada from the 120+ mattresses we have reviewed, we evaluate each mattress against 40+ criteria, assessing its cooling features, materials, and construction.
Below, we’ll explain what makes a mattress sleep cooler and highlight the best cooling mattresses available in Canada today.
Best Overall | Best Hybrid | Best Budget |
|---|---|---|
Octave Vista is our top recommendation for hot sleepers thanks to its advanced cooling technologies, strong pressure relief, and excellent value with a free bedding bundle.

For most Canadians, the best cooling mattress isn’t necessarily the one with the most cooling features. It’s the one that stays comfortable throughout the night while still providing the support your body needs.
That’s why the Octave Vista earned our top spot.
Its high cooling performance comes from multiple cooling layers working together. The CryoFusion™ cooling cover helps draw heat away from your body as soon as you lie down, giving the mattress a cool-to-the-touch feel. Its copper-infused gel foam comfort layer, which is infused with phase-change material, helps regulate the mattress’s temperature by dissipating heat. And finally, its breathable Elastex® foam and channelled support layer both help increase airflow in the mattress, allowing hot air to escape efficiently.
The Octave Vista also provides excellent support with its five-zoned support system. This design delivers pressure relief and targeted support where you need it most, preventing you from sinking too much in areas like your back and hips and keeping you cool throughout the night.
Unlike many cooling mattresses that cost well over $2,000, the Octave Vista delivers exceptional cooling performance at the much more accessible price of $1,099 for a queen.

If you prefer the responsive feel of a hybrid mattress, the Douglas Summit Hybrid is our top recommendation.
Hybrid mattresses are naturally more breathable than most all-foam mattresses because their coil system creates open channels that help heat escape. The Douglas Summit Hybrid leverages this design while offering excellent comfort and support.
The Douglas Hybrid sets itself apart with great comfort and cooling features that beat many other hybrids. Its 2.5″ layer of ecoLight™ Cooling Gel Foam is infused with Polar® temperature-balancing technology to keep the surface temperature in check, so you don’t overheat at night. Plus, the Exoforge™ pocket coils let air flow through the mattress, helping to get rid of extra heat better than typical all-foam designs while giving great support for your lower back and hips.
The result is a hybrid mattress that nails the balance between cooling, pressure relief, responsiveness, and support, making it a solid pick for anyone who tends to sleep hot but still wants the advantages of both foam and coils.

While the following mattresses offer advanced cooling features that made them contenders for hot sleepers, they ultimately fell short of our top pick when evaluated against our other performance criteria:
Cooling claims are easy to make, but not all cooling mattresses perform equally. When comparing options, we recommend that you keep an eye out for the following areas.
The most effective cooling mattresses typically combine several temperature-regulating features rather than relying on a single cooling layer. Having 2 or more of these features tends to increase the mattress’s cooling effects. Some of the most effective cooling features include:
As Nicola points out, “the most effective cooling mattresses usually combine multiple technologies that work together to manage heat throughout the night.” This is one reason the Octave Vista earned our top recommendation. It combines a cooling cover, copper-infused memory foam, phase-change material, and breathable comfort layers to help create a cooler sleep environment.
For most hot sleepers, a medium-to-medium-firm feel offers the best balance of comfort, support, and temperature regulation. Very soft mattresses can create a “cocoon effect,” as your body sinks deeper into the comfort layers. “While that sounds cozy, it actually traps body heat and blocks airflow around your skin,” explains Power.
A longer sleep trial gives you more time to determine whether a mattress truly helps you sleep cooler, as cooling performance can feel different depending on the season, your bedding, and your bedroom temperature.
We recommend choosing a mattress with at least a 100-night sleep trial whenever possible. Both Octave and Douglas offer a generous 365-night sleep trial, while Juno comes with 120-night sleep trial.
Many people assume their body cools down after they fall asleep, but the cooling process actually begins before bedtime. As Power explains, your core body temperature naturally drops in the 40 to 90 minutes before sleep, helping you fall asleep faster and transition into deeper, more restorative sleep.
When your sleep environment is too warm, or your mattress traps heat around your body, that process becomes more difficult. You may find yourself tossing and turning, waking up during the night, or struggling to get comfortable.
A cooling mattress won’t directly change your body temperature, but it can help reduce heat buildup around your body while you sleep. This can be especially beneficial if you:
Your mattress is only one part of a cooler sleep environment. Breathable bedding, a cooler bedroom temperature, and improved room airflow can also help improve sleep comfort.
Nicola’s Tip: Taking a warm bath or showering 1 to 2 hours before bed may actually help you cool down faster and fall asleep more easily. Research suggests this can support deeper, more restorative sleep.
The following mattresses are ranked by their overall rating; however, their cooling capabilities played a major role in securing their positions. Our evaluation took into account the quantity and effectiveness of each bed’s temperature-regulation features and airflow design to ensure hot sleepers find the best possible balance of comfort and cooling.

Costco-Exclusive Hybrid Mattress
Octave Vista is our top pick for the best cooling mattress in Canada because of its combination of advanced cooling technologies, strong pressure relief, and accessible price of just $1,099 CAD for a queen. It earned 8.0/10 for its cooling features and 9.8/10 for overall performance, based on the third-party testing we commissioned. The Octave Vista has a medium-firm feel that works well for most sleep positions.
For hot sleepers who prefer a hybrid mattress, we recommend the Douglas Summit Hybrid. For shoppers on a tighter budget, the Juno Hybrid is a good budget-friendly option.
The best cooling mattresses combine several cooling features rather than relying on a single "cooling" layer. To choose the best mattress for hot sleepers, we recommend focusing on the following four key factors:
"Combining these 4 factors will support your body's natural ability to release heat throughout the night,” explains Nicola. She recommends combining materials that improve airflow, wick moisture, and dissipate heat because temperature regulation relies on multiple factors working together.”
Traditional closed-cell memory foam is known for trapping heat. However, modern cooling foam mattresses have improved significantly. Advanced materials such as copper-infused foam, gel foam, and open-cell foam can help address many of the heat-retention issues traditionally associated with foam.
The Octave Vista, for example, is a memory foam mattress with a 8.0/10 cooling features score that combines several advanced cooling features, allowing it to outperform several hybrids in our lineup. The materials and technology used matter more than whether a mattress is foam or hybrid.
For many hot sleepers, yes, a cooling mattress is worth it. But it’s no magic wand. Medical experts like Nicola explain that your bed setup isn’t just about comfort, it also affects your sleep environment by trapping or releasing heat. She recommends choosing a mattress and bedding that help your body cool down, which can help you fall asleep faster. So if overheating regularly disrupts your sleep, upgrading to a cooling mattress can make a noticeable difference.
Gel foam can help absorb and disperse heat, making a mattress feel cooler than traditional memory foam.
However, the best cooling mattresses don't rely solely on gel foam. They typically combine it with other features, such as breathable covers, copper-infused foam, or airflow-promoting support layers. This type of multi-layer system helps increase cooling performance throughout the night. The Octave Vista is a good example of a mattress that does this really well.
When excess heat builds up around you, it can make it harder to stay comfortable and asleep. Your body naturally cools down as you sleep. If your mattress or blankets trap heat, they interfere with your body’s natural cooling process. Many hot sleepers experience more tossing and turning, frequent wake-ups, and less restorative sleep as a result.
Nicola Power warns: “Sleep quality has a direct impact on how well the brain and body function. This makes good quality sleep a foundational factor in both daily function and long-term health.”
Most sleep experts recommend keeping your bedroom between 18°C and 20°C (65°F and 68°F).
Pairing a cooler room with a breathable mattress, lightweight bedding, and good airflow can help create a more comfortable sleep environment.
In addition to choosing a cooling mattress, consider:
Small changes throughout your sleep setup can add up to a noticeably cooler night's sleep.
A cooling mattress is often a good compromise because it helps prevent excess heat buildup without making the bed feel cold.
Many couples also use separate duvets, sometimes called the Scandinavian sleep method, so each person can choose the warmth level that works best for them. Investing in a Split Queen or King can also be beneficial for couples with different sleep preferences."
Yes, although it isn't a complete solution.
A cooling mattress can help reduce the heat that builds up around your body while you sleep, which may make night sweats feel less disruptive and help you fall back asleep more comfortably.
For best results, pair your mattress with breathable bedding and a cool bedroom environment.
You can, but many weighted blankets trap heat.
If you enjoy the feeling of a weighted blanket, look for options specifically designed for hot sleepers, with breathable covers and cooling materials.
These third-party engineers apply a consistent testing process to every mattress using a detailed framework. Every mattress is tested the same way, whether it’s foam or hybrid. Because these types perform differently, we rate them on separate scales to ensure the scores are fair and meaningful.
We believe independent testing is essential to producing reliable and meaningful comparisons. That's why all test results are reviewed and signed off by an APEGA-certified engineer, operating under a strict code of ethics.
We use the testing results and over 40 criteria to build our scoring methodology.
Tests and reviews without this level of professional oversight may be more prone to errors and unintended bias.
