Foam Core/No Coils Sealy® Edge Support Mattresses Compatible with Adjustable Bed Mattress Selector

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.
Sealy mattresses are engineered for dependable, body-aligning support — many featuring Posturepedic Technology that reinforces the centre third where you need it most. Compare every option below by feel, size, and price.
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
