NM mattresses are National Mattress's own line — quality construction at honest, direct prices across firmness levels and builds. Compare every option below by feel, size, and price.
Sealy mattresses are engineered for dependable, body-aligning support — many featuring Posturepedic Technology that reinforces the centre third where you need it most. Compare every option below by feel, size, and price.
Breathable mattresses are built to move air, not trap it. Through ventilated and open-cell foams, breathable knit and Tencel covers, and pocket-coil airflow, they let heat and moisture escape instead of building up under you — so your sleep surface stays fresher, drier and more comfortable through the night. It's a great fit if you sweat at night, live in a humid climate, or just don't like that stuffy, sunk-in feel. You'll find breathable builds across every brand — Sealy, Serta, Beautyrest, iComfort, Tempur-Pedic, Chirofoam and our own NM line — in foam, hybrid and pocket-coil. Sleep especially hot? See our cooling mattresses for active heat-wicking. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it means: airflow-focused builds that let heat and moisture escape instead of trapping them • How it works: ventilated/open-cell foams, breathable knit & Tencel covers, pocket-coil airflow • The benefit: a fresher, drier, less stuffy sleep surface • Best for: sweaty sleepers, humid climates, or anyone who dislikes a sunk-in, stuffy feel • Sleep hot?

How Cooling Materials Work in Modern Mattresses

A mattress’s cooling performance depends on its overall construction. Gel infusion can delay the initial warming of foam by increasing thermal mass; it does not provide a continuing path for heat to leave the bed. Natural latex has an open-cell structure that promotes continuous airflow without any added chemicals, and hybrid mattresses with individually wrapped coils create air channels beneath the comfort layers that vent heat away from the sleep surface.

When choosing a cooling mattress, match the technology to your sleep style. Hot sleepers who prefer a conforming feel can compare memory foam models from Serta, Serta iComfort, or Tempur-Pedic, paying attention to airflow and cover construction. If you want natural breathability without synthetic foams, Natura and Sealy Posturepedic Natural Origins offer latex-based options. Budget-conscious shoppers can find cooling gel foam mattresses from Springwall and NM. All cooling mattresses at National Mattress are manufactured in Canadian factories 🍁 and ship with free express delivery across Canada.

❄️

Gel-Infused Foam

Thermal-conductive gel beads absorb and dissipate body heat. Found in many models from Serta, Sealy, Beautyrest, and Springwall.

💨

Coil Airflow Systems

Individually wrapped pocket coils in innerspring and hybrid mattresses create air channels that continuously vent heat from the core.

🌱

Graphite & Copper Infusions

Compare the complete construction of Serta iComfort and Beautyrest models. An infusion name alone does not establish sustained cooling performance.

🧊

Cooling Cover Fabrics

Phase-change and moisture-wicking cover materials feel cool to the touch and regulate surface temperature throughout the night.

Frequently Asked Questions About Cooling Mattresses

What type of cooling mattress is best for hot sleepers?
Hybrid mattresses with gel-infused foam over pocket coils tend to sleep coolest because the coil system provides continuous airflow beneath the comfort layers. Latex models also sleep naturally cool due to their open-cell structure. Both types are available at National Mattress from brands like Sealy, Beautyrest, and Springwall.
What is the difference between gel foam, graphite foam, and latex for cooling?
Gel infusion increases foam’s thermal mass, slowing initial warming until it reaches equilibrium. Sustained ventilation depends on airflow through the foam, coils and cover. Latex has an open-cell structure, but compare the complete mattress rather than choosing by one material name.
How much do cooling mattresses cost at National Mattress?
Cooling mattresses at National Mattress span a range of budgets in Queen size. Budget gel foam models from Springwall and NM are the most affordable, mid-range options from Serta and Sealy fall in the middle, and premium models from Tempur-Pedic and Stearns & Foster sit at the top of the range. All orders include free delivery across Canada.
Are cooling mattresses available in all sizes?
Yes. National Mattress carries cooling mattresses in Single/Twin, Twin XL, Double/Full, Queen, King, and RV Short Queen sizes. Most models are available in all six sizes, with Twin XL popular for adjustable bed bases and King ideal for couples who both sleep warm.
Do cooling mattresses come with a sleep trial?
Every cooling mattress at National Mattress includes a 365-night sleep trial, the longest in Canadian mattress retail. This gives you a full year to confirm the cooling performance works for your body temperature and sleep habits, with hassle-free returns if it doesn’t.
Can I use a cooling mattress on an adjustable bed base?
Most cooling mattresses at National Mattress are compatible with adjustable bed bases. Foam, memory foam, latex, and hybrid models all flex with adjustable frames. Only some traditional innerspring models with rigid coil systems may not be suitable, check the product page or ask our sleep experts.

Not Sure Which Cooling Technology Is Right for You?

Our non-commissioned sleep experts can match you with the right cooling mattress based on your sleep position, body temperature, and budget, no sales pressure.
