Extra Firm Natural & Organic Mattresses Adjustable Bed Base Friendly Default Category
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
For a cleaner, more eco-conscious sleep, our natural and organic mattresses are built with materials you can feel good about — natural Talalay latex, organic cotton and wool covers, plant-based and soy-derived foams, and recycled fibres, with low-VOC, CertiPUR-US® certified components. They're a great fit if you want fewer synthetic chemicals, more sustainable materials, or a naturally breathable, hypoallergenic feel. You'll find genuinely certified-organic options — like GOTS organic cotton and organic latex from Natura and Evergreen — alongside natural-material and eco-friendly builds from Serta iComfort ECO, Sealy, Beautyrest and our own NM line. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What "natural materials" means: Talalay latex, organic cotton & wool, plant-based/soy foams and recycled fibres • Certified-organic options: GOTS organic cotton and organic latex (Natura, Evergreen) • Eco-friendly builds: Serta iComfort ECO (REPREVE recycled) plus low-VOC, CertiPUR-US® foams • Best for: shoppers who want fewer synthetic chemicals, sustainable materials, or a naturally breathable feel • Looking specifically for latex?
