How Cooling Materials Work in Modern Mattresses

Cooling mattresses use engineered materials that actively draw heat away from your body rather than simply trapping it in foam layers. Gel-infused memory foam absorbs and redistributes body heat through thermal-conductive gel beads, while graphite-infused foam transfers heat up to 4× faster than standard polyurethane. 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 pressure-relieving feel should look at gel or graphite memory foam models from Serta, iComfort, or Tempur-Pedic. 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 starting under $300 (Queen). 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 95+ 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

Advanced conductor materials in iComfort and Beautyrest models draw heat away from the body at accelerated rates.

🧊

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 foam uses thermal-conductive gel beads to absorb and redistribute heat. Graphite foam transfers heat faster through carbon particles and is found in premium iComfort and Beautyrest models. Latex is naturally breathable with an open-cell structure — it doesn’t trap heat in the first place, making it ideal for sleepers who prefer chemical-free cooling.
How much do cooling mattresses cost at National Mattress?
Cooling mattresses at National Mattress range from approximately $240 to $5,690 in Queen size. Budget gel foam models from Springwall and NM start under $300, mid-range options from Serta and Sealy run $500–$1,500, and premium models from Tempur-Pedic and Stearns & Foster range from $1,750 to $5,690. 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.
