Firm Copper, Charcoal or Graphite Infusion Memory Foam Serta® Compatible with Adjustable Bed 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?

These mattresses blend copper, charcoal, graphite or similar minerals into their foam layers or cover fabric. These materials conduct heat well, helping move warmth away from your body, and are also used to help keep the mattress fresh by resisting odour. A good place to start if you sleep warm and want cooling built into the materials themselves.
Every mattress here has at least one layer of memory foam, in the comfort layers or quilted into the cover. Memory foam softens with body heat and slowly moulds to your shape, easing pressure at the shoulders and hips and absorbing movement. You will find it in all-foam beds and in hybrids, where it sits above pocket coils. For all-foam memory foam beds only, use Mattress Type.
Serta mattresses balance comfort and support with cooling-gel foams and proven coil systems, from a name trusted in Canadian bedrooms for decades. Compare every option below by feel, size, and price.
