These features regulate surface temperature and reduce heat fluctuations by absorbing or releasing heat as needed throughout the night.Best Hybrid with Targeted Support: Sealy PosturepedicThe Posturepedic Hybrid series features over 700 individually wrapped coils to promote breathability alongside moisture-wicking covers. The Sealy Posturepedic series is often cited as a reliable choice for those needing a cooling hybrid that balances cost and performance.
Why Hybrids and Latex Sleep Cooler
There are plenty of options when it comes to materials and interior construction for your mattress, but understanding the science behind them will help you find one that will keep you cool. Independent testing from organizations like Sleep Foundation confirms that hybrid and latex mattresses typically sleep cooler than all-foam models.
How Mattress Materials Affect Sleep Temperature
Coil MechanicsPocketed coils in hybrid mattresses, like those in the Endy Hybrid, create vertical channels for air circulation. These actively draw heat away from the sleep surface, preventing the “oven effect” (the tendency of materials to absorb, trap and radiate body heat back to a sleeper) often felt in traditional memory foam beds.Latex PropertiesNatural latex is inherently breathable with an open-cell structure that resists heat retention, unlike dense traditional memory foam. This makes it a preferred material for those who want a resilient, cool-to-the-touch surface.Memory Foam TradeoffTraditional memory foam is commonly used in mattresses and conforms closely to the body, but the tradeoff is that it can trap body heat, leading to a hotter night’s sleep. To mitigate this, look for open-cell foam or gel-infused options.Open-Cell InnovationIf you’re still looking for the extra level of comfort and support from foam but want to avoid the heat trapping properties of traditional memory foam, open-cell foam is a better alternative. The Endy Hybrid uses a signature open-cell foam that allows air to pass through and move between layers for superior regulation.Our open-cell foam is also CertiPUR-US® certified, meaning it is made without harmful chemicals and has low VOC emissions so you can sleep easy knowing it is safe for even the most sensitive household members, including infants and the elderly.
What to Look for in a Cooling Mattress
Use this quick checklist to be sure that your cooling mattress purchase is the best one for you:
Prioritize Material: Choose a hybrid mattress (pocket coils with a layer of foam) or one made of natural latex. Avoid mattresses made of thick traditional memory foam, as they tend to trap heat.
Ventilated Foams: If choosing a mattress with foam layers, ensure they are ventilated or feature an open-cell structure to facilitate heat dissipation.
Temperature-Neutral Foam: As your body warms up, temperature-neutral foam won’t absorb the heat. Not only does that keep you cool, it keeps the mattress from getting too soft so you still get the support you need.
Hypoallergenic: If you suffer from allergies, choose a mattress made with hypoallergenic materials so it doesn’t trigger any allergies that may cause you to overheat.
Support for Your Style: Consider your sleep position and body weight to ensure the mattress doesn't allow excessive sinkage, which can restrict airflow and trap heat.
Trial Period: Ensure that the mattress you choose has a long trial period (at least 90 nights) to test cooling performance in your own bedroom across different seasons.
phase-change materials (PCM)?
The Endy Hybrid checks all these boxes: pocketed coils for airflow, breathable open-cell foam, and a 365-night trial—one of the longest in the industry.
Choosing the Right Cooling Mattress for Your Sleep Style
Your sleep position and weight play a major role in how much heat your mattress retains, as they determine how much of your body remains in contact with the sleep surface. Without proper alignment and support, you may sink too deeply into the materials, which restricts airflow and traps body heat.
Side Sleepers: Medium-Firm
This is the most common sleeping style. If you sleep on your side, you need pressure relief at the shoulders and hips. A medium-firm hybrid mattress (like the Endy Hybrid) provides cushioning at these key pressure points maintaining excellent airflow through its coil core.Avoid overly firm mattresses that create pressure points and can cause you to toss and turn, raising your body temperature. You should also avoid overly soft or thick traditional memory foam mattresses that can "envelop" a side sleeper, creating a literal heat trap around the torso and legs.
Back Sleepers: Medium-Firm to Firm
If you sleep on your back, you need lumbar support to prevent the spine from bowing, which can lead to both back pain and increased heat retention.Medium-firm to firm hybrids or latex work best for this purpose. The Endy Hybrid’s pocketed coils provide targeted support for the lumbar region while maintaining breathability. By staying "on top" of the mattress rather than "in" it, more of your body’s surface area is exposed to the air, allowing for better natural thermoregulation.
Stomach Sleepers: Firm
Stomach sleeping is often the "hottest" position because the front of the body—where we often feel heat most intensely—is in full contact with the bed.Stomach sleepers need firmer support to prevent hip sinkage, which can lead to spinal misalignment and increased heat retention as the body dips into the mattress. Consider a firmer hybrid or latex option, as these materials are more resilient and resist the "sinking" feeling that traditional foam provides.
Body Weight Considerations
Your weight affects how materials compress, which directly impacts breathability.Lighter sleepers (under 130lbs) may not compress the mattress enough to engage the cooling coils. They may prefer slightly softer hybrid options to ensure they get the comfort they need without sacrificing airflow.Those over 230 lbs typically need firmer, more supportive mattresses to prevent excessive sinkage. Coil-based hybrids are ideal for this group because the coils provide the structural integrity needed to maintain airflow.
What If You Already Have a Mattress?
Changing your mattress is a big commitment in terms of both the money and time it takes to replace it. If you already have a mattress and are looking for a cooler night’s sleep, here are several ways to optimize your sleep environment:
Change Up Your Bedding: Swap synthetic fabrics or heavy flannels for natural, airy sheets like 100% organic cotton in a percale weave for optimal breathability. Moisture-wicking sheets made from bamboo or TENCEL™ can also help extend the lifespan of your current bed. For more tips on how to choose the best sheets for hot sleepers, check out our post here.
Choose the Right Mattress Protector: Many waterproof protectors trap heat because they use non-porous materials to block liquids, which also restricts airflow.Choose a breathable mattress protector made from TENCEL™ fibres to wick away moisture and sweat while you sleep.
Adjust Room Temperature: If possible, bring your bedroom temperature down and ensure proper air circulation with fans or open windows.
Manage Stress Levels: Stress activates cortisol, which can increase body heat production. Establish nighttime rituals like journaling or meditation to enter a "zen" state before bed, and keep your work outside of the bedroom if possible.
Consider Cooling Accessories: Consider a 2-3 inch gel-infused or latex cooling topper to add a breathable layer between you and a hot mattress.
Seasonal Duvets: Use a summer-weight duvet or a year-round option with a 100% cotton shell for comfort through every Canadian season.
These ideas can extend your current mattress's usability and create a cooler sleeping environment overall. However, if your mattress is over 7 years old or showing signs of sagging, a new mattress provides better long-term value.
Conclusion: Investing in Your Sleep
Maintaining a cooler body temperature is associated with deeper, more restorative sleep. High temperatures can interfere with melatonin production and disrupt REM cycles. By choosing a mattress with the right material science—like the Endy Hybrid with its breathable foam and airflow-promoting coils—you can finally stop waking up drenched in sweat and start getting the rest you deserve.For more information on the best mattress for hot sleepers in Canada, visit the Endy Hybrid page to learn about our 365-night trial and 15-year warranty.
