Firm Medium Mattresses Springwall Adjustable Bed Compatible Mattresses attresses with a Removable Cover Springwall Mattresses
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

Not every mattress can bend with an adjustable base — but these can. Every mattress here is built to flex with the head and foot articulation of an adjustable base without damaging the comfort layers, so you can read, relax in Zero-Gravity or elevate your legs with confidence. In fact, over 90% of our mattresses are adjustable-compatible, spanning memory foam, hybrid and pocket-coil constructions from every brand — NM, Sealy, Serta, Beautyrest, Tempur-Pedic, Stearns & Foster and more — at every budget from about $109 to premium. Foam and hybrid models flex most easily, while rigid, thick tight-top innersprings generally don't. Pair any of these with one of our adjustable bases, and every mattress comes with a 365-night sleep trial and free delivery across Canada. • What this means: mattresses built to flex with an adjustable base's head & foot articulation • Over 90% of our mattresses are adjustable-compatible — every brand, every budget ($109+) • Best constructions for adjustable bases: memory foam, hybrid and pocket-coil • What usually won't work: rigid, thick tight-top innersprings that don't bend • Pairs with our adjustable bases (including split-king for independent sides) • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
Hundreds of our mattresses come with a removable, washable cover — unzip and take it off to machine-wash or spot-clean, which is great for allergies, kids, spills and keeping your bed fresh between deep cleans. These are mostly our foam, memory foam, gel-foam, latex and hybrid models — the bed-in-a-box-style builds — and they span value to luxury: NM, Springwall and Chirofoam, the Sealy Cocoon series, Serta iComfort and iComfort ECO latex, and Tempur-Pedic. You'll find every firmness from plush to extra firm, from about $109 to premium. Every mattress includes a 365-night sleep trial, price-match guarantee and free delivery across Canada. • What it means: a removable cover you can unzip to machine-wash or spot-clean • Great for: allergies, kids, spills, and keeping your mattress fresh • A large selection — mostly foam, memory foam, latex and hybrid (boxed-style) builds • Spans value to luxury: NM, Springwall, Chirofoam, Sealy Cocoon, Serta iComfort & iComfort ECO, Tempur-Pedic • Firmness from plush to extra firm, from about $109 to premium • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
