Firm Luxury Cooling Technology All Mattresses

Firm mattresses give you a solid, supportive surface with minimal sink — keeping your spine aligned and making it easier to move and get in and out of bed. They're the top choice for back and stomach sleepers, heavier bodies, and anyone who finds softer beds uncomfortable. Compare every firm option below by brand, profile, and price.
Luxury mattresses are our finest — the best materials, advanced support systems, and premium comfort layers from our top luxury brands. They're for shoppers who want the ultimate in comfort, durability, and craftsmanship and won't compromise. Compare every luxury option below by brand, type, and feel.
Cooling-technology mattresses use gel-infused foams, phase-change covers, or cooling fibres that actively pull heat away from your body — ideal for hot sleepers who wake up overheated. Compare every cooling option below by brand, type, and feel.

Shop 200+ mattresses from Serta, Beautyrest, Sealy, Tempur-Pedic, Springwall, and Stearns & Foster at National Mattress — available in Single/Twin through King sizes from $99 to $6,640. Choose from innerspring, euro-top, memory foam, hybrid, and latex constructions in four firmness levels from extra firm to plush. Every mattress is manufactured in Canadian factories using CertiPUR-US® certified foams and ships free across Canada with a 365-night sleep trial, price match guarantee, and manufacturer warranty coverage up to 25 years.
