Firm Extra Firm Medium Couples Back Sleeper Adjustable Bed Base Friendly All
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
Medium-firmness mattresses — often called medium-firm — sit right between plush and firm, which is why they're the most popular and versatile feel we carry. You get enough cushioning to relieve pressure with enough support to keep your spine aligned, making medium a safe choice for back sleepers, combination sleepers who change positions through the night, and couples who need a compromise between two preferences. Shop medium models from Sealy, Serta, Beautyrest, Stearns & Foster, iComfort and Tempur-Pedic across memory foam, hybrid, euro-top, pillow-top and tight-top builds — with free delivery across Canada. • Feel: medium sits between plush and firm — balanced and the most versatile of our four comfort levels • Also called "medium-firm" — the middle of the firmness scale • Best for: back sleepers, combination sleepers, couples, and most body types • Consider plush if you sleep on your side; firm if you sleep on your stomach or want more support • Constructions: euro-top, tight-top, pillow-top, memory foam and hybrid • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort, Tempur-Pedic, Springwall & NM • Prices: from $171 to premium
Two people on one mattress creates problems one person never has. One of you gets up early, the other feels it. One sleeps hot, the other is cold. One wants firm, the other wants plush. A mattress for couples has to handle all three. Motion isolation is the first thing to look at. Individually pocketed coils and memory foam absorb movement where a traditional connected innerspring passes it straight across the bed. Edge support is the second, because on a shared mattress the usable sleeping surface is whatever you can lie on without feeling like you might roll off, and weak edges quietly cost you several inches on each side. If your comfort preferences genuinely differ, ask about split configurations rather than compromising on one feel. All seven of our Ontario showrooms let you lie on these together, which is the only real way to test motion transfer. Every one carries the 365-night sleep trial.
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
