Firm Medium Springwall® NM® 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? See our extra-firm mattresses
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
