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.

💰

Save 20–50% Off Retail

Direct-from-manufacturer pricing on Sealy, Serta, Beautyrest, and Tempur-Pedic — no commissioned salespeople, no retail markups.

🛡️

Full Warranty on Sale Items

Every sale mattress carries the same manufacturer's warranty (up to 25 years) and 365-night sleep trial as full-price models.

🚚

Free Canada-Wide Delivery

Free express shipping on orders over $199, with most orders dispatched same or next day from our Ontario warehouse.

🍁

Canadian-Made Quality

100% of our mattresses are manufactured in Canada with CertiPUR-US® certified foams — sale price, full quality.

Frequently Asked Questions About Mattress Sales

Are sale mattresses lower quality than regular-priced mattresses?
No. Every mattress on our sale page is a full-specification model from brands like Sealy, Serta, and Beautyrest — with identical construction, materials, and warranty coverage. Sale pricing reflects our wholesale model and volume purchasing, not reduced quality.
Do sale mattresses still qualify for the sleep trial and warranty?
Yes. All sale mattresses include the full 365-night sleep trial and the complete manufacturer’s warranty (ranging from 1 to 25 years depending on the model). There are no exceptions for discounted items.
Can I price match if I find the same mattress on sale elsewhere?
Yes. National Mattress’s price match guarantee applies to sale items. If you find an identical mattress advertised for less at another Canadian retailer, we’ll match the price and beat it by 10% of the difference — with 365-day post-purchase protection.
What types of mattresses go on sale at National Mattress?
Our sale page includes eurotop/pillowtop, memory foam, hybrid, innerspring, and foam-core mattresses in all sizes from Single/Twin to King. Deals range from clearance and last-chance inventory to featured promotions on current collections.
How do I choose the right mattress during a sale?
Start with your sleep position: side sleepers generally need plush or medium for pressure relief, while back and stomach sleepers benefit from firm to extra firm support. Use our mattress selector tool or speak with a non-commissioned sleep expert for personalised guidance.
Does National Mattress offer financing on sale mattresses?
Yes. 0% financing options are available on sale mattresses, letting you spread the cost into manageable payments. Combined with free delivery on orders over $199, you can upgrade your sleep without paying full price upfront.

Not Sure Which Sale Mattress Is Right for You?

Our non-commissioned sleep experts can help match you to the right mattress at the best price — no pressure, just honest guidance backed by real product knowledge.
