Quick Answer: Costco carries Sealy queen mattresses in the $600 to $900 CAD range with warehouse-exclusive model numbers. These queens typically have 600 to 800 pocket coils, below the 1,000+ coil count many sleep specialists recommend for full queen-size support. The trade-off is lower price versus firmer edge support and longer lifespan from higher-coil models.
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."
How does the Sealy queen at Costco actually perform after the first 6 months? Talia at Mattress Miracle gets this question from customers who are eyeing the $600 to $900 price tag and wondering if it is truly a deal. "The Sealy name pulls people in," Talia says. "But the model Costco carries is not the same Sealy you would find at a mattress retailer. The build is completely different."
Current Sealy Queen Models at Costco
Costco Canada rotates Sealy queen inventory seasonally, but the warehouse typically stocks two to three models at any given time. Every model carries a warehouse-exclusive SKU number that cannot be cross-referenced with Sealy's retail catalogue.
| Feature | Sealy Entry Queen | Sealy Mid-Range Queen | Sealy Premium Queen |
|---|---|---|---|
| Price (CAD) | $600-$650 | $700-$800 | $850-$900 |
| Coil Count | 600-650 | 700-750 | 750-800 |
| Comfort Layer | 1" foam | 1.5" gel foam | 2" gel memory foam |
| Profile Height | 10" | 11" | 12" |
| Edge Support | Basic foam encasement | Basic foam encasement | Foam encasement |

The exact model names change frequently. What stays consistent is the specification range: 600 to 800 coils across the lineup, with comfort layers between 1 and 2 inches of standard or gel-infused foam.
What the Specs Actually Mean
Numbers on a mattress tag tell a story that most shoppers miss. Here is what to look for:
What Each Spec Means for Your Sleep
- Coil count (600-800): Each coil supports roughly 0.08 to 0.10 square inches of your body. Fewer coils means each one bears more weight, creating pressure points and accelerating wear
- Comfort layer (1-2"): This is the foam between your body and the coils. Under 2 inches, most sleepers feel the coils within 12 to 18 months as the foam compresses
- Profile height (10-12"): A thicker mattress does not automatically mean better. The thickness distribution matters more. A 12-inch mattress with only 2 inches of comfort foam has 10 inches of base and coils
- Edge support: Basic foam encasement provides minimal edge stability. Sitting on the edge or sleeping near it results in roll-off within the first year

Costco Sealy vs Retail Sealy Queens
Walk into a Sleep Country or mattress specialty store and ask for a Sealy Posturepedic queen. You will find models with 900 to 1,200 coils, 3 to 4 inches of layered comfort foam, reinforced edge support systems, and zoned coil configurations that provide firmer support under hips and softer cushioning under shoulders.
The Costco version carries the Sealy name but uses a simplified coil system, thinner comfort layers, and basic edge support. The warehouse-exclusive model number ensures you cannot compare the two side by side using online specifications.
The Model Number Trick
Try searching the exact model number from your Costco Sealy queen online. You will find zero results outside of Costco's own website. This is by design. Manufacturers create unique SKUs for warehouse retailers specifically to prevent price comparison with their retail channel.
The Coil Math on Queen Mattresses
A queen mattress measures 60 by 80 inches, giving you 4,800 square inches of sleeping surface. The coil count determines how many independent support points share that load:
| Mattress | Coils | Sq. Inches per Coil | Support Quality |
|---|---|---|---|
| Sealy Costco Entry | 600 | 8.0 | Basic |
| Sealy Costco Premium | 800 | 6.0 | Moderate |
| Sealy Retail Mid-Range | 1,000 | 4.8 | Good |
| Restonic ComfortCare | 1,222 | 3.9 | Premium |
↔ Scroll to see full table
The Restonic ComfortCare queen provides one coil for every 3.9 square inches of sleeping surface. The Costco Sealy entry queen provides one coil for every 8.0 square inches. That is more than double the coverage per coil, which translates directly into better pressure relief and longer mattress life.
Comfort Layer Differences That Matter
Beyond coil count, the comfort layers above the coils determine how the mattress feels in years two through ten. The Costco Sealy queen uses 1 to 2 inches of standard or gel-infused foam. This foam typically has a density of 1.8 to 2.5 lb/ft³.
Brad at Mattress Miracle explains what happens: "That density compresses quickly under body weight. Within 18 months, you feel the coils through the comfort layer, especially under your hips and shoulders. Premium mattresses use foam at 3.5 to 5.0 lb/ft³ density, which holds its shape for years."
Sealy Costco Queen vs Restonic ComfortCare Queen
| Specification | Sealy Costco Queen (Best) | Restonic ComfortCare Queen |
|---|---|---|
| Price (CAD) | $850-$900 | $1,619 |
| Coil Count | 750-800 | 1,222 |
| Price per Coil | $1.06-$1.20 | $0.92 |
| Comfort Layer | 2" gel foam | Multi-layer premium system |
| Edge Support | Basic encasement | Reinforced perimeter |
| Showroom Testing | Plastic-wrapped display | Full comfort test |

At $0.92 per coil, the Restonic ComfortCare queen delivers better material value than the Costco Sealy at $1.06 to $1.20 per coil. You get 53% more coils for 25% more money.

Call 519-770-0001How much is a Sealy queen mattress at Costco Canada?
Sealy queen mattresses at Costco Canada range from $600 to $900 CAD depending on the model tier. Entry-level models start around $600, mid-range around $700 to $800, and the premium warehouse options reach $850 to $900.
Is the Costco Sealy queen the same as the retail version?
No. Costco carries warehouse-exclusive Sealy models with unique SKU numbers that differ from retail versions. The Costco models typically have fewer coils (600-800 vs 900-1,200), thinner comfort layers, and simplified edge support compared to the retail Sealy Posturepedic line.
How many coils does a Sealy queen at Costco have?
Costco Sealy queens typically have 600 to 800 pocketed coils. The entry-level models have around 600 to 650 coils, while the premium models reach 750 to 800. By comparison, the Restonic ComfortCare queen has 1,222 coils at $1,619.
Is a Sealy queen from Costco worth it?
For a short-term or guest room mattress, the Sealy entry queen at $600 offers basic comfort. For your primary bed where you sleep 7 to 8 hours nightly, the lower coil count and thinner comfort layers will show wear within 2 to 3 years. A higher-coil mattress provides better long-term value per night of sleep.
Can I return a Sealy queen to Costco if I do not like it?
Yes. Costco Canada accepts mattress returns at any time with no deadline. However, returning a queen mattress requires transport back to the warehouse, which typically requires a truck or SUV. Testing properly before buying saves this hassle entirely.
