Plush Extra Firm Mattresses with Cooling Materials
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 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.
