Hypoallergenic mattresses are made to resist the things that trigger allergies and disrupt sleep — dust mites, mould, mildew and bacteria — using antimicrobial and naturally resistant cover materials like bamboo and Tencel, plus CertiPUR-US® certified, low-VOC foams. The result is a cleaner, fresher sleep surface that's gentler on sensitive skin and easier on allergy and asthma sufferers. You'll find hypoallergenic builds across brands like Sealy, Serta, Beautyrest, iComfort, Springwall, Evergreen and our own NM line, in foam, hybrid and pocket-coil. If allergies or sensitivities affect your sleep, start here. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it means: built to resist dust mites, mould, mildew and bacteria • How it works: antimicrobial and naturally resistant covers (bamboo, Tencel) plus CertiPUR-US®, low-VOC foams • Best for: allergy and asthma sufferers, sensitive skin, and anyone who wants a cleaner sleep surface • The benefit: fewer allergens, a fresher feel, gentler on sensitivities • Across brands and builds: foam, hybrid and pocket-coil • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
