Firm Medium Sealy® Posturepedic® Edge Support Mattresses Compatible with Adjustable Bed Cooling Mattresses Mattress Selector

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
Sealy® Posturepedic® mattresses are expertly designed to deliver targeted support for healthy sleep posture. This renowned collection combines sturdy coils and pressure-relieving foams to provide Canadians with deep, restorative comfort night after night.
Edge support mattresses are reinforced around the perimeter so the edge feels as solid as the middle — you can sleep right up to the side without that sinking, roll-off feeling, sit on the edge to get dressed without it caving, and use the full surface of the bed. It's a feature that matters most for couples sharing the space, anyone who sits on the edge to get in and out of bed, and heavier-weight sleepers. These are mostly our pocket-coil and hybrid mattresses with full-perimeter coils or foam-encased edges — from Springwall (Full Perimeter Comfort Pockets), Sealy, Serta, Beautyrest, iComfort, Stearns & Foster and our own NM line. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it does: a reinforced perimeter so the edge stays firm — no sinking or rolling off • Why it matters: more usable sleep surface, easier to sit on the edge and get in and out of bed • Best for: couples sharing space, anyone who sits on the edge, and heavier-weight sleepers • How it works: full-perimeter pocket coils or foam-encased edges (mostly coil & hybrid; all-foam edges are softer) • Brands: Springwall (Full Perimeter Comfort Pockets), Sealy, Serta, Beautyrest, iComfort, Stearns & Foster & NM • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
If you sleep hot, the right mattress can make all the difference. Our cooling mattresses are built to draw heat away from your body and keep you comfortable all night — using cooling technologies like gel-infused memory foam, cool-to-the-touch and phase-change covers, graphite and copper infusions, and breathable pocket-coil airflow. You'll find cooling builds across every brand — Sealy, Serta, Beautyrest, iComfort, Tempur-Pedic, Chirofoam and our own NM line — in foam, hybrid and pocket-coil, from plush to firm. If you wake up sweaty or run warm at night, start here. Every mattress includes a 365-night sleep trial, price-match guarantee and free delivery across Canada. • Best for: hot sleepers, night sweats, or anyone who runs warm • Cooling technologies: gel-infused memory foam, cool-to-the-touch & phase-change covers, graphite/copper infusions, breathable coil airflow • Builds: gel memory foam, hybrid and pocket-coil • Across every brand and firmness, plush to firm • Why it helps: draws heat away and improves airflow so you sleep cooler • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
