Medium Plush Extra Firm Mattresses With Antimicrobial Fabrics and Materials

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
Plush mattresses are the softest comfort level we carry — built with thick pillow-top and euro-top comfort layers (plus plush memory foam and hybrid options) that cradle your shoulders and hips for a soft, sink-in feel. Plush is the top choice for side sleepers and lighter-weight sleepers who need extra cushioning at the pressure points; back and stomach sleepers, or anyone who wants firmer support, may prefer our medium or firm options. Shop plush models from Sealy, Serta, Beautyrest, Stearns & Foster, iComfort and Tempur-Pedic in memory foam, hybrid and pocket-coil builds — with free delivery across Canada. • Feel: plush is the softest of our four comfort levels (plush, medium, firm, extra firm) • Best for: side sleepers and lighter-weight sleepers — cushions shoulders and hips • Consider firmer if: you sleep on your back or stomach, are heavier, or want more support • Plush constructions: pillow-top, euro-top, plush memory foam and hybrid • Builds: memory foam, hybrid and pocket-coil • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort & Tempur-Pedic • Prices: from $224 to premium
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.

🍁

Canadian-Made Quality

Manufactured in Canada with free delivery, a 365-night sleep trial, and price-match guarantee.

Frequently Asked Questions About Antimicrobial Mattresses

Do antimicrobial mattress fabrics actually work?
Yes. Technologies like Serta® Antimicrobial Fibre and Sealy® CleanProtect™ are engineered into the fabric at the manufacturing stage to inhibit bacterial growth on the mattress surface. They work continuously and do not diminish with use. Read our detailed breakdown on how antimicrobial fabrics work.
Are antimicrobial mattresses good for allergy sufferers?
Antimicrobial fabrics help reduce bacteria and odour on the sleep surface, but for full allergy protection, look for models also labelled hypoallergenic with CertiPUR-US® certified foams. Pairing with a mattress protector adds a washable dust-mite barrier for the most complete defence.
Which brands at National Mattress offer antimicrobial mattresses?
Six brands carry antimicrobial models: Serta and iComfort (CoolFeel Fabric™ + Antimicrobial Fibre), Sealy (CleanProtect™), Beautyrest (Antimicrobial Fibre Technology), Springwall, and Evergreen. Prices range from $179 to $6,640 across 64 models.
Do I still need a mattress protector with an antimicrobial mattress?
A protector is still recommended. Antimicrobial fabrics inhibit bacteria on the surface, but a mattress protector adds waterproof and dust-mite-proof coverage that keeps your warranty valid and extends the mattress lifespan. See our complete protector guide for options.
What sizes and firmness levels are available in antimicrobial mattresses?
Antimicrobial mattresses at National Mattress are available in Single/Twin, Twin XL, Double/Full, Queen, and King sizes. Firmness options span extra firm, firm, medium, and plush across eurotop, tight-top, memory foam, hybrid, and organic latex constructions.
Do antimicrobial mattresses stop odour and keep the mattress fresh?
Antimicrobial treatments target the bacteria that cause mattress odour, helping the sleep surface stay fresher between cleanings. They are not a substitute for regular care, but they significantly slow bacterial buildup. Learn more in our guide on whether antimicrobial fabrics prevent mattress odour.
