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 are backed by the manufacturer warranty terms.

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 run from budget-friendly to luxury across a wide range of 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.
