If you find yourself tossing and turning at night because of overheating, you’re not alone. Many sleepers struggle to stay cool, in the summer but also year-round. If you naturally run hot, you’re likely dreaming of sweat-free sleep. The good news: advances in mattress and bedding technology can help you achieve a cooler, more comfortable sleep. In this guide, we’ll break down the key features of cooling mattresses, how to choose the right one, the best cooling mattresses in Canada, and extra tips for beating the heat.
Why do hot sleepers need a cooling mattress?
Sleeping hot can disrupt your sleep cycle, cause night sweats, and leave you feeling groggy in the morning. A cooling mattress can make a world of difference by actively drawing heat away from your body and promoting airflow, so you can wake up refreshed and well-rested.
Key features & technologies in cooling mattresses
When shopping for a mattress, hot sleepers should look out for these must-have features:
Open-cell foam
Mattresses made with open-cell foam, like the Signature Foam with AirScape® Technology in The Casper Mattress, allow for better airflow, keeping you cool as you sleep.
Pocketed coils
Similarly, hybrid mattresses with a layer of coils result in better air circulation, preventing heat from building up. Casper’s Original Hybrid Mattress and Wave Hybrid Snow Mattress both have a layer of individually pocketed springs.
Gel pods
Another cooling feature to keep an eye out for is gel pods. They promote cooling by absorbing, distributing, and dissipating body heat away as you sleep, preventing a hot sleep environment.
For example, Casper Canada’s award-winning Wave Hybrid Snow Mattress contains a layer of Align Foam with Gel Support Pods and Zoned Support™ to simultaneously provide ergonomic support and cooling comfort.
Phase change materials
Phase change materials (PCMs) in mattresses work to regulate temperature by absorbing heat when the body is hot and releasing it when the body is cooler. So if you sleep hot, look for mattresses containing these materials, as they will keep you at an optimal temperature throughout the night.
Casper’s Wave Hybrid Snow Mattress contains a layer of Casper Signature Foam with Cooling Phase Change Material and AirScape® Technology to soothe you to sleep and regulate your body temperature.
HeatDelete™ Bands
HeatDelete™ Bands are a key component of Casper’s signature Snow Technology™. These bands are specially engineered to continuously pull heat away from your body for 12+ hours so you sleep without interruptions. They are a critical layer in Casper Canada’s cooling Wave Hybrid Snow Mattress (along with other Casper cooling sleep essentials).
Cooling covers
Hot sleepers will love the cool-to-the-touch sensation of a polyethylene mattress cover. Polyethylene is known to provide a cooling effect in mattresses and mattress protectors (check out Casper’s cooling QuickCool™ Mattress Protector) by enhancing breathability and heat dissipation.
Casper’s QuickCool™ Cover contains polyethylene, offering that “cool-to-the-touch” sleep experience. Test out our QuickCool™ Cover for yourself on our Wave Hybrid Snow Mattress.
How to choose the best cooling mattress
Not all cooling mattresses are created equal. Here’s how to narrow down your options:
Identify your sleep position
The position you sleep in will influence what type of mattress is for you, helping you choose between hybrid vs. memory foam mattresses, and firmness levels.
Soft mattresses like the Wave Hybrid Snow Plush are typically designed for side sleepers who can benefit from extra cushioning around their shoulders and hips. Oppositely, firm mattresses, like the Wave Hybrid Snow Firm, are best for stomach and back sleepers who require a harder sleep surface. Medium or Medium-firm mattresses are often suitable for all sleep positions.
Ensure the mattress you pick balances cooling with the right firmness for your needs.

Check the materials
Now that you know the features and materials of cooling mattresses, look for these when you go shopping. Before selecting a mattress, check that it has phase change materials, open-cell foam, a layer of springs or coils, and/or a polyethylene cover.
Consider your budget
Cooling features can add to the price, but investing in quality sleep is always worth it. Plus, many brands offer generous trial periods and warranties. Casper Canada offers a 100-night trial on every mattress, as well as a 10-Year Limited Warranty.

Extra tips for hot sleepers
Beyond choosing the right mattress, try these strategies to improve sleep temperature:
Pick lightweight, breathable bedding
Opt for sheets made from breathable materials like cotton, linen, or TENCEL™. Casper has two cooling sheets: Percale Sheets and SuperSoft TENCEL™ Sheets. Percale sheets have a cotton weave, while the SuperSoft TENCEL™ Sheets are made of 100% TENCEL™ Lyocell. Both are available as sheet sets, duvet covers, and pillowcase sets.
To sleep even cooler, top your cooling mattress with a QuickCool™ Mattress Protector. This will not only guard your mattress against stains and dirt, but it will also help you sleep cooler.
Keep your room at an optimal temperature
To prevent overheating throughout the night, set your thermostat between 60 and 67°F (16 to 19°C), use fans, or open a window when possible.
Choose your pillow wisely
Did you know that cooling pillows exist? Just like cooling mattresses, there are pillows specially designed for hot sleepers. Casper Canada’s Hybrid Snow Pillow and Foam Snow Pillow are made with the same patented Snow Technology™ as our Wave Hybrid Snow Mattress. Keep your head and neck cool all night long with a cooling pillow (and don’t forget to add a cooling pillow protector—shop QuickCool™ Pillow Protectors).
Drink water before bed
Drinking water throughout the day can prevent dehydration, which can lead to night sweats.
Take a cool shower in the evening
A quick way to lower your core body temperature is by taking a cool shower before bed. Doing so can help you fall asleep faster and remain cooler throughout the night.
Wear pyjamas made from moisture-wicking materials
Just like how hot sleepers should choose breathable sheets and bedding, they should also choose breathable sleepwear. Opt for sweat-wicking fabrics, like linen, cotton, bamboo, and TENCEL™ Lyocell.
Consider cooling accessories
For a boost of cool while you sleep, consider a mattress topper with cooling capabilities, like the Casper Comfy Mattress Topper featuring Airscape® Technology, or a cooling mattress protector and pillow protectors, like Casper’s QuickCool™ Mattress Protector and QuickCool™ Pillow Protectors.
