Extra Firm Medium Canada Temperature Regulating Mattresses

Extra firm mattresses are the firmest, most supportive feel we carry — a hard, no-sink surface that holds your body on top of the mattress rather than letting it settle in. They're built for stomach sleepers, heavier-weight sleepers and anyone who finds a standard firm mattress still too soft, delivering maximum support and spinal alignment. Most use a tight-top or high-density foam construction (including orthopedic Chirofoam), with budget-friendly options that keep extra-firm support affordable. Shop Beautyrest, Serta, Chirofoam, Springwall and our own NM line — from $152, with free delivery across Canada. • Feel: extra firm is the firmest of our four comfort levels — a hard, no-sink surface • Best for: stomach sleepers, heavier-weight sleepers, and anyone who wants maximum support • Choose this over firm if a standard firm mattress still feels too soft • Consider firm or medium if you sleep on your side or want any cushioning • Constructions: tight-top and high-density foam (including orthopedic Chirofoam) • Brands: Beautyrest, Serta, Chirofoam, Springwall & NM • Prices: from $152 — an affordable, value-focused selection
Medium-firmness mattresses — often called medium-firm — sit right between plush and firm, which is why they're the most popular and versatile feel we carry. You get enough cushioning to relieve pressure with enough support to keep your spine aligned, making medium a safe choice for back sleepers, combination sleepers who change positions through the night, and couples who need a compromise between two preferences. Shop medium models from Sealy, Serta, Beautyrest, Stearns & Foster, iComfort and Tempur-Pedic across memory foam, hybrid, euro-top, pillow-top and tight-top builds — with free delivery across Canada. • Feel: medium sits between plush and firm — balanced and the most versatile of our four comfort levels • Also called "medium-firm" — the middle of the firmness scale • Best for: back sleepers, combination sleepers, couples, and most body types • Consider plush if you sleep on your side; firm if you sleep on your stomach or want more support • Constructions: euro-top, tight-top, pillow-top, memory foam and hybrid • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort, Tempur-Pedic, Springwall & NM • Prices: from $171 to premium

How Temperature Regulating Mattresses Keep You at the Right Sleep Temperature

Temperature regulating mattresses go beyond simple cooling — they actively respond to your body heat using phase-change materials, gel-infused foams, graphite layers, and breathable cover fabrics that absorb excess warmth and release it as you cool down. Unlike a standard cooling mattress that passively dissipates heat, temperature regulating designs work in both directions, helping hot sleepers stay comfortable in summer and preventing that too-cold feeling in winter. Research suggests the ideal sleep temperature range is 15.5–19.5°C (60–67°F), and these mattresses are engineered to help your body stay within that window throughout the night.

At National Mattress, our temperature regulating collection spans 250+ models across euro-top, tight-top, memory foam, hybrid, and latex constructions. Key technologies include Serta’s CoolFeel™ Fabric, Beautyrest’s InfiniCool™ surface layers, Sealy’s SealyCool™ covers, and Tempur-Pedic’s Sleep Climate™ cooling yarn — each approaching temperature regulation differently. When choosing, consider your sleep position, body weight, and whether you share the bed: pocket coil and hybrid models offer better airflow through the core, while all-foam models with graphite or copper infusions provide targeted heat dissipation at the comfort layer.

🌡️

Active Temperature Response

Phase-change materials and gel-infused foams absorb heat when you’re warm and release it as you cool, maintaining a balanced sleep surface all night.

❄️

Cooling Cover Fabrics

Technologies like CoolFeel™, InfiniCool™ MAX, and Cold PE fabric provide an instantly cool-to-the-touch sleep surface that wicks moisture away.

💨

Breathable Core Design

Pocket coil, hybrid, and breathable foam cores promote continuous airflow, preventing heat from being trapped inside the mattress.

🍁

Canadian-Made Quality

Over 85% of our temperature regulating mattresses are manufactured in Canadian factories with free delivery and manufacturer warranty coverage up to 15 years.

Frequently Asked Questions About Temperature Regulating Mattresses

What is the difference between a temperature regulating mattress and a cooling mattress?
A cooling mattress passively dissipates body heat using breathable materials and airflow. A temperature regulating mattress actively responds to your body temperature — absorbing excess warmth when you’re hot and releasing stored heat when you cool down, using phase-change materials, gel-infused foams, or graphite layers.
Which mattress type regulates temperature best: hybrid, foam, or latex?
Hybrid and latex mattresses generally regulate temperature most effectively because their coil or latex cores allow continuous airflow. All-foam models with graphite or copper infusions can also perform well, though they rely on conductive cooling rather than ventilation.
Can a temperature regulating mattress help with night sweats or hot flashes?
Temperature regulating mattresses may help reduce discomfort from night sweats and hormonal temperature swings by actively absorbing excess body heat. Pairing a temperature regulating mattress with moisture-wicking sheets and a breathable mattress protector can further improve overnight comfort.
Will a mattress protector reduce the temperature regulating effect?
A thick, non-breathable protector can block the cooling surface from making direct contact with your body. Choose a thin, breathable protector — like the HealthGuard Cool Silk Tencel line available at National Mattress — to preserve airflow and maintain temperature regulating performance.
Do temperature regulating features wear out over time?
Gel-infused foams and graphite layers retain their thermal properties for the life of the mattress. Surface-level phase-change treatments may gradually diminish after several years of use. All temperature regulating mattresses at National Mattress include manufacturer warranty coverage of 5–15 years for added peace of mind.
Do National Mattress temperature regulating mattresses ship free across Canada?
Yes. National Mattress offers free express delivery across Canada on all mattress orders, plus a 365-night sleep trial so you can test the temperature regulating performance in your own bedroom. A price match guarantee ensures you get the best price available.

Not Sure Which Temperature Regulating Mattress Is Right for You?
