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?
