How to Find Real Mattress Deals Without Sacrificing Quality
Not all mattress sales are created equal. The best sale mattresses come from current-year collections by established manufacturers, not stripped-down models built for discount pricing. At National Mattress, every sale item is a full-specification mattress from brands like Sealy, Serta, Beautyrest, and Tempur-Pedic — with identical warranty coverage, 365-night sleep trial, and free Canada-wide delivery as regular-priced models. Our wholesale pricing model eliminates commissioned salespeople and retail markups, passing savings of 20–50% directly to shoppers.
When comparing sale mattresses, focus on three things: construction type (choose from eurotop, memory foam, hybrid, or innerspring based on your sleep position), firmness level (extra firm through plush), and certifications like CertiPUR-US® that confirm foam safety. 100% of our mattresses are manufactured in Canadian factories 🍁, and our price match guarantee ensures you always get the lowest advertised price — plus we beat competitors by 10% of the difference.
