Quick Answer: Among cooling mattress brands in Canada, Restonic offers the best value with real cooling construction (1,222 coils in the ComfortCare Queen at $1,619) provides premium body-matched cooling, and Sleep In delivers natural bamboo temperature regulation. Sealy and Casper have cooling claims but rely more on surface treatments than structural airflow.

Every mattress brand claims their product "sleeps cool." It is right up there with "premium comfort" as the most overused phrase in the industry. But cooling is not a marketing claim you can just slap on a label. It is a physical property that depends on materials, construction, and design.
At Mattress Miracle, we carry Restonic, and Sleep In, and we have compared them all against competitors like Sealy and Casper that our Brantford customers ask about. Here is an honest, brand-by-brand breakdown of how each one actually performs on temperature.
How Different Brands Approach Cooling
Mattress cooling comes from three places: the core (coils or foam), the comfort layer (latex, gel, memory foam), and the cover fabric. Some brands invest in all three. Others focus on one and hope you will not notice the others.
Understanding Cooling Claims
A mattress cover that feels cool to the touch in a showroom may not stay cool after you lie on it for an hour. Gel infusion absorbs heat for 20 to 30 minutes, then reaches equilibrium. Coil airflow works continuously. Natural materials like latex and wool regulate temperature passively but permanently. When comparing brands, ask: "What is the cooling mechanism, and does it last all night?"
We have tested every brand we carry, and we have had customers report back on brands we do not carry. That feedback, gathered over 38 years, is more valuable than any lab test because it reflects real sleeping conditions, not controlled environments.
Restonic: Coil Airflow and Copper Latex
Restonic is manufactured in Surrey, British Columbia, making it a genuinely Canadian product. Their cooling strategy centres on high coil counts and smart material layering rather than gimmicky surface treatments.
Cooling Technology by Model
| Model | Queen Price | Coils | Cooling Features |
|---|---|---|---|
| ComfortCare | $1,619 | 1,222 | Individually wrapped coils for airflow, breathable knit cover |
| Revive Reflections ET | $2,395 | 1,200 | Flippable dual-sided, airflow through coils, Euro top ventilation |
| Luxury Silk & Wool | $2,395 | 884 zoned | Natural wool (temperature regulating), silk fibres (moisture wicking), zoned coils |
| Revive Tiffany Rose/Jasmine | $2,995 | 1,188 | Talalay copper latex (thermal conductivity + open-cell airflow) |
| Revive St Charles/Elizabeth | $3,150 | 1,188 | 15" flagship, multi-layer cooling with copper latex |
Brad's take: "The ComfortCare is our most recommended mattress for hot sleepers on a budget. Those 1,222 coils are not just for support. Each one creates an air channel. When you shift at night, air pumps through those channels like a bellows. No amount of gel infusion can match continuous airflow."
The Restonic Revive Cooling Edge
The Tiffany Rose and Jasmine models use Talalay copper latex, which attacks heat from two angles. The Talalay process creates an extremely open cell structure for breathability, while copper particles embedded in the latex conduct heat away from your body five times faster than standard foam. It is the most effective cooling comfort layer we have on our showroom floor.

Restonic: Body Diagnostic Cooling
Restonic takes a different approach. Their proprietary Body Diagnostic System maps your body's pressure points and matches you with a mattress that provides targeted support. The cooling benefit comes indirectly: when your mattress properly supports your body, you sink less deeply into the surface, maintaining more airflow between your body and the mattress.
Restonic Cooling Strengths
Restonic manufactures in Toronto, Shawinigan (Quebec), and Alberta, giving them Canadian production across multiple facilities. Their premium models use:
- Individually wrapped coil systems with ventilated borders
- High-density comfort foams with better heat dissipation than standard memory foam
- Breathable covers with moisture-wicking properties
- Zoned support that prevents deep sinking (which traps heat)
Our experience: Restonic sleeps cooler than average because of solid construction quality. They do not market specific cooling technologies as aggressively as some brands, but their mattresses consistently perform well in temperature regulation. Customers who buy Restonic rarely come back complaining about heat.
Sleep In: Natural Bamboo Cooling
Sleep In is a Canadian brand that uses bamboo-derived fabrics in their covers and comfort layers. Bamboo viscose is naturally moisture-wicking and breathable, giving Sleep In mattresses a distinct cooling advantage in humid conditions.
How Bamboo Cools Differently
Bamboo cooling is not the same as gel or copper cooling. It works through moisture management rather than thermal conductivity. Bamboo fibres can absorb up to three times more moisture than cotton, and they release that moisture to the air faster. This accelerates evaporative cooling at the sleep surface.
In southern Ontario's humid summers, this moisture management becomes particularly valuable. Dorothy notes: "Gel cools by absorbing heat. Bamboo cools by managing sweat. For customers who wake up damp, bamboo often works better than gel because it addresses the moisture problem directly."
Sleep In mattresses are Canadian-made and flippable, which means you get two sleep surfaces from one mattress. Some customers flip to the firmer side in summer, finding it retains slightly less heat due to less conforming.
Sealy: Posturepedic Cooling Technology
Sealy is one of the largest mattress brands globally, and their cooling claims are prominent in their marketing. The Posturepedic and Posturepedic Plus lines feature what Sealy calls "moisture-wicking cover fabric" and various foam technologies.
Honest Assessment
Sealy makes good mattresses, but their cooling technology is not their strongest feature. Most Sealy models rely on gel-infused memory foam or polyurethane foam for their comfort layers. As we discussed in our cooling materials guide, gel infusion provides short-term cooling (20 to 30 minutes) but does not offer sustained temperature regulation throughout the night.
The Sealy Posturepedic Plus Hybrid models with coil systems perform better on temperature than their all-foam models. If you are considering Sealy specifically for cooling, look at their hybrid options rather than the all-foam Cocoon or standard Posturepedic lines.
Sealy is widely available at Sleep Country, Costco, and other major retailers. The advantage is easy access and frequent sales. The trade-off compared to Restonic is that Sealy's volume manufacturing does not always match the coil counts and material quality of smaller, more focused brands.
Casper: AirScape Foam Approach
Casper was a pioneer in the online mattress space and is now owned by Sleep Country in Canada. Their cooling strategy relies on what they call AirScape foam, an open-cell polyurethane foam with small holes punched through it for airflow.
How AirScape Works
AirScape foam is essentially perforated foam. The holes allow some air movement through the comfort layer, which is an improvement over solid memory foam. However, perforated foam still retains more heat than coils, latex, or even standard open-cell foam.
The Casper Original (all-foam) is one of the warmer mattresses in its price range. The Casper Hybrid, which adds a coil base, performs meaningfully better on temperature because you get coil airflow underneath the foam layers.
Why We Do Not Carry Casper or Sealy
Customers in Brantford sometimes ask why we carry Restonic instead of bigger names like Sealy or Casper. Brad's answer is straightforward: "We chose brands where the construction matches the claims. When I open a Restonic and count 1,222 coils, or feel the Talalay copper latex in a Revive, I know what the customer is getting. Some of the bigger brands rely on brand recognition to sell mattresses that, component by component, do not justify the price. We would rather sell you fewer products that we genuinely stand behind."

Which mattress brand is best for hot sleepers in Canada?
Based on our testing and customer feedback over 38 years, Restonic provides the best combination of cooling performance and value. The ComfortCare's 1,222 individually wrapped coils create genuine airflow, while the Revive line adds copper latex for thermal conductivity. Both are manufactured in British Columbia.
Does Restonic sleep cool?
Restonic sleeps cooler than average due to quality construction with proper coil systems and ventilated designs. While they do not market specific cooling technologies as prominently as some brands, their mattresses consistently perform well for temperature regulation. We carry Restonic at our Brantford showroom.
Is Casper good for hot sleepers?
The all-foam Casper Original is one of the warmer mattresses in its price range. If you prefer Casper, choose the Casper Hybrid, which adds a coil base that improves airflow significantly. The AirScape foam alone does not provide enough cooling for people who overheat regularly.
Are Sleep In bamboo mattresses really cooler?
Sleep In bamboo covers manage moisture effectively, which creates a cooling effect through faster evaporation. This is particularly effective in humid environments like southern Ontario summers. Bamboo cooling works differently from gel or coil cooling. It addresses dampness more than raw heat.
Can I compare cooling mattress brands at Mattress Miracle?
Yes. We carry Restonic, and Sleep In in our Brantford showroom at 441 1/2 West Street. Talia can walk you through each brand's cooling technology and let you lie on them side by side. Spending five to ten minutes on each mattress is the best way to feel the temperature difference between brands.
