Quick Answer
The best times to buy a Costco mattress in Canada are during their seasonal event sales in January, May (Victoria Day), July (Canada Day), September (Labour Day), and November (Black Friday). Typical savings: $50-$200 off regular pricing. However, even sale-price Costco mattresses still use 800 coils and 2. 5 lb foam. Call (519) 770-0001.
Brad, Owner, 40+ years of experience: "We have been helping Brantford families sleep better since 1997. Every customer gets personal attention, honest advice, and the kind of follow-up service you just do not get from big box stores."
Waiting for the right Costco sale to buy your mattress? You're not alone. Thousands of Canadian shoppers time their purchases around Costco's promotional calendar, hoping to save an extra $100-$200. But is the timing of your purchase really what matters most?
"People spend months waiting for a Costco mattress sale while sleeping on a mattress that's already worn out," Brad at Mattress Miracle observes. "They save $150 on a mattress that'll need replacing in three years. The math doesn't support the strategy."

January: New Year Clearance
January is when Costco clears out the previous year's mattress models to make room for new inventory. This creates some genuine deals:
- $50-$150 off select Novaform models
- Occasional Sealy markdowns as models rotate
- Online-only flash deals on costco.ca
- Previous-season models at clearance pricing
The catch: clearance models are being discontinued for a reason. Manufacturers update models when the previous version underperforms, and clearance stock often has the lowest specs in the lineup.
Spring & Summer Sale Events
Victoria Day (May) and Labour Day (September) are traditionally the two biggest mattress sale weekends in Canada, and Costco participates with event pricing:
- $100-$200 instant rebates on featured mattress models
- Bundle deals with pillows or mattress protectors
- Free delivery upgrades on select online orders
- Executive member additional savings on some items
Black Friday & Boxing Day
Black Friday (late November) offers the deepest Costco mattress discounts of the year. Boxing Day (December 26) has slimmer pickings but occasional clearance gems.
Black Friday Reality Check
- Deepest discounts: $150-$250 off on marquee models
- But: selection is limited, popular sizes sell out quickly
- Some "Black Friday" models are specifically manufactured for the event with lower specs
- Online deals start earlier (often the Monday before)
- You still cannot test the mattress before buying
Online-Only Deals on Costco.ca
Costco.ca occasionally offers mattress deals not available in warehouses. These tend to pop up mid-month without much fanfare:
- Flash sales lasting 3-5 days
- Warehouse-exclusive models at online-only prices
- Bundle offers with bed frames or bedding
- Free delivery promotions
Worst Times to Buy a Costco Mattress
Avoid Buying During
- February-March: Full retail pricing, new inventory at highest prices
- August: Back-to-school focus, minimal mattress promotions
- October: Pre-Black Friday holding pattern, no deals yet
- December (early): Between Boxing Day and regular pricing, worst of both worlds
Sale Price vs Real Value: The Bigger Picture
Here's what sale timing enthusiasts miss: even with the best Black Friday deal, a Costco mattress still has the same construction limitations.
| Scenario | Price Paid | Coils | Lifespan | Cost/Year |
|---|---|---|---|---|
| Costco Queen (regular price) | $700 | 800 | 3 years | $233/yr |
| Costco Queen (Black Friday) | $500 | 800 | 3 years | $167/yr |
| Restonic ComfortCare Queen | $1,619 | 1,222 | 8-10 years | $112-$141/yr |
↔ Scroll to see full table
Even Costco's best Black Friday price ($167/year) costs more annually than the Restonic ComfortCare at full retail ($112-$141/year). And the Restonic is available any day of the year at Mattress Miracle, no sale-watching required.
- Restonic ComfortCare pricing is consistent year-round
- No waiting for sales, no rushing before deals expire
- 1,222 pocketed coils and 3.0+ lb foam at every price point
- Test in person any day of the week
- White glove delivery included at no extra charge
- Buy when you're ready, not when a sale calendar dictates

Call 519-770-0001Frequently Asked Questions
Does Costco Canada have mattress sales?
Yes, around Victoria Day (May), Canada Day (July), Labour Day (September), Black Friday (November), and January clearance. Savings range $50-$250.
When is the cheapest time to buy a mattress at Costco?
Black Friday offers the deepest discounts at $150-$250 off. Even at sale price, annual cost exceeds Restonic ComfortCare due to shorter lifespan.
Do Costco Executive members get extra mattress discounts?
Executive members earn 2% cash back on purchases. On a $700 mattress that's $14 back. Some events offer additional Executive pricing.
Should I wait for a Costco mattress sale?
Waiting saves $50-$250 but every month of poor sleep on a worn mattress has health costs exceeding sale savings.
Are Costco mattress prices negotiable?
No. Costco uses fixed pricing with no haggling or price matching. Their model relies on volume purchasing power.
