Firm Memory Foam Foam Core/No Coils Compatible with Adjustable Bed Edge Support 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
Memory foam mattresses contour to your body, relieving pressure at the hips and shoulders while absorbing motion so you won't feel your partner move. They give a cradling, "hug" feel that suits side sleepers and couples. Browse every memory foam option below by brand, feel, and profile.
Foam core mattresses are built entirely from foam with no innerspring coils, for quiet, motion-free sleep and a consistent, supportive surface. They're lightweight, pair perfectly with platform and adjustable bases, and suit couples sensitive to movement. Compare every all-foam, no-coil option below by brand and feel.
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
