Firm Extra Firm Premium Mattresses NM® Mattresses and Accessories

Firm mattresses give you the most support of our everyday comfort levels — a solid, stable surface that keeps your spine aligned instead of sinking in. Firm is the go-to for back and stomach sleepers, heavier-weight sleepers who need extra support, and anyone looking for orthopedic, back-friendly comfort; side sleepers or those who like a softer feel may prefer our medium or plush options. Choose from tight-top, foam, euro-top and hybrid builds across Sealy, Serta, Beautyrest, Stearns & Foster, iComfort, Tempur-Pedic, Chirofoam and our own NM line — from budget-friendly models at $59 to premium, with free delivery across Canada. • Feel: firm gives a solid, supportive surface with minimal sink-in • Best for: back and stomach sleepers, heavier-weight sleepers, and orthopedic / back-pain support • Consider softer if you sleep on your side or want more cushioning — see our medium or plush options • Constructions: tight-top (most firm beds), foam, euro-top and hybrid • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort, Tempur-Pedic, Chirofoam, Springwall & NM • Prices: from $59 (budget) to premium — our widest price range • Want the firmest feel?

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
Premium is the sweet spot between everyday value and luxury — name-brand mattresses with better materials, thicker comfort layers and more advanced support, without the flagship price tag. This is where you'll find recognizable comfort lines like Sealy Posturepedic Plus, Serta Perfect Sleeper and Perfect Day, Beautyrest Harmony, Chirofoam memory foam and Springwall Chiropractic — in euro-top, pillow-top, hybrid, memory foam and even organic latex builds, across every firmness from plush to extra firm. Most premium mattresses run from about $400 to $1,400. Every one includes a 365-night sleep trial, price-match guarantee and free delivery across Canada. • What "premium" means: name-brand comfort and upgraded materials — a step up from value, below the luxury flagships • Featured lines: Sealy Posturepedic Plus, Serta Perfect Sleeper & Perfect Day, Beautyrest Harmony, Chirofoam, Springwall Chiropractic • Builds: euro-top, pillow-top, hybrid, memory foam and organic latex • Every firmness from plush to extra firm • Typically about $400 to $1,400 • Looking higher or lower? See our luxury or great-value mattresses • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
