Firm Great Value Mattresses Compatible with Adjustable Bed All 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?

Great Value is where comfort meets affordability — our most budget-friendly mattresses, starting around $109. These are quality beds, not corner-cut compromises: supportive high-density foam, pocket-coil euro-tops and tight-tops, many made right here in Canada by our own NM and Springwall lines, alongside entry-price models from Sealy, Serta and Beautyrest. Whether you're furnishing a guest room, a kids' room, a rental or a first apartment — or you just don't see the point in overpaying — you'll find a comfortable, well-built mattress here for less. Every one includes a 365-night sleep trial, price-match guarantee and free delivery across Canada. • What "great value" means: our most affordable mattresses — quality builds at low prices, from $109 • Builds: high-density foam, pocket-coil euro-top and tight-top • Mostly Canadian-made value brands (NM, Springwall) plus entry models from Sealy, Serta & Beautyrest • Best for: guest rooms, kids' rooms, rentals, first apartments, or anyone who wants comfort without overpaying • Same guarantees as every mattress: 365-night sleep trial, price-match & free Canada-wide delivery • Stepping up?
