Medium Extra Firm Mattresses With Antimicrobial Fabrics and 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 Antimicrobial Mattress Fabrics Work and What to Look For
Antimicrobial mattress fabrics use silver-ion treatments, copper infusions, or engineered fibre technologies to inhibit the growth of odour-causing bacteria and common allergens on the sleep surface. At National Mattress, brands like Serta, Sealy, and Beautyrest each integrate proprietary antimicrobial systems — including Serta® CoolFeel Fabric™ with Antimicrobial Fibre, Sealy® CleanProtect™ Cover Technology, and Beautyrest® Antimicrobial Fibre Technology — directly into the mattress cover and quilt layers for continuous protection that does not wash out over time.
When comparing antimicrobial mattresses, consider what lies beneath the cover as well: hypoallergenic foams certified by CertiPUR-US® ensure the entire mattress — not just the surface — is free of harmful chemicals. Pairing an antimicrobial mattress with a quality mattress protector adds a washable barrier layer for maximum hygiene. All antimicrobial mattresses at National Mattress are manufactured in Canadian factories, ship with free delivery across Canada, and include a 10–15 year manufacturer’s warranty.
Built-In Antimicrobial Protection
Silver-ion and engineered fibre treatments in the cover and quilt layers actively inhibit bacteria and odour without washing out.
CertiPUR-US® Certified Foams
Every antimicrobial mattress uses independently tested foam free of ozone depleters, heavy metals, formaldehyde, and PBDEs.
Cooling + Clean Sleep
Most models pair antimicrobial fabrics with cooling technology and breathable covers to manage moisture and temperature.
