Extra Firm Mattresses for Back Sleepers Mattresses for Standard Bed Frames NM® Mattresses and Accessories
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
If you sleep on your back, your mattress needs to support the natural curve of your spine — firm enough that your hips don't sink, with just enough give to fill the gap at your lower back. That's why back sleepers do best on our medium and medium-firm mattresses, which balance support and contouring across foam, hybrid, euro-top and tight-top builds. We carry hundreds of back-sleeper-friendly models from every brand — Sealy, Serta, Beautyrest, Tempur-Pedic, iComfort, Stearns & Foster, Chirofoam and our own NM line — from about $59 to premium. Every mattress includes a 365-night sleep trial and free delivery across Canada. • Why it matters: back sleeping needs support that keeps the spine neutral and fills the lumbar curve • Best feel for back sleepers: medium to medium-firm (support without sinking) • Works across builds: foam, hybrid, euro-top and tight-top • Hundreds of options across every brand, from about $59 to premium • Prefer firmer support, or sleep with back pain? See our firm mattresses • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
These mattresses are built for a standard bed frame, box spring or platform bed rather than an adjustable base — solid, no-flex support for a classic setup. Shopping by feel or build instead? Browse by comfort (plush, medium, firm) or by type (memory foam, hybrid, pocket coil, traditional). Using an adjustable base? See our adjustable-bed-compatible mattresses. Every order includes a 365-night sleep trial and free delivery across Canada.
