Firm Extra Firm Serta® 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

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 a wide range of 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.
