Have you been eyeing the Sealy Hollycourt Posturepedic at your local Costco? It is one of the most searched Costco mattress models in Canada, and for good reason. The name "Sealy" carries decades of brand recognition, and the Costco price tag feels like a deal. But our team at Mattress Miracle in Brantford sees customers every week who bought the Hollycourt expecting premium support and ended up disappointed within 18 months. Here is what the spec sheet actually tells you.
Sealy Hollycourt Posturepedic: Full Specifications
What Costco Does Not Tell You

Why 800 Coils Falls Short at the Queen Size
A queen mattress measures 60 by 80 inches, giving you 4,800 square inches of sleeping surface. With approximately 800 coils, the Hollycourt provides about 0.17 coils per square inch. The Restonic ComfortCare queen packs 1,222 pocketed coils into that same area, delivering 0.25 coils per square inch. That is 53% more support points under your body.
Dorothy's Observation
"When couples test the Hollycourt versus Restonic side by side, the first thing they notice is motion transfer. With 800 coils, movement ripples across the bed. With 1,222 individually pocketed coils, one partner can toss and turn without the other feeling it."Each coil in a pocketed system works independently. More coils means more precise contouring around your shoulders, hips, and lumbar region. Fewer coils create broader pressure zones that cannot adapt to your unique body shape, leading to pressure points that cause tossing and turning.
Foam Density: The Hidden Durability Factor
The comfort layers in the Sealy Hollycourt use foam rated at approximately 2.5 lb per cubic foot. This is standard for warehouse-channel mattresses but sits below the durability threshold that sleep engineers recommend for mattresses expected to last 8 to 10 years.
Here is what foam density means in practice:
- 2.0 to 2.5 lb/ft³: Budget range. Expect noticeable body impressions within 18 to 24 months for average-weight sleepers
- 2.5 to 3.0 lb/ft³: Mid-range. Holds shape for 3 to 5 years under regular use
- 3.0 to 4.0 lb/ft³: Premium range. Maintains support for 7 to 10 years. This is what Restonic uses in the ComfortCare line
Talia at Mattress Miracle explains it simply: "When the foam breaks down, the coils start poking through. That is when people come in saying their two-year-old mattress feels like a decade-old one."
Price vs. Value: What Your Dollar Actually Buys
Cost Per Coil Comparison
At approximately $900 CAD for the Hollycourt queen with 800 coils, you pay $1.13 per coil. The Restonic ComfortCare queen at $1,619 with 1,222 coils costs $0.92 per coil. You get 53% more coils for just 25% more money.The Costco price looks attractive at first glance, but the math tells a different story when you factor in longevity. If the Hollycourt develops body impressions at year three and you need to replace it, your effective cost doubles to $1,800 over six years. The Restonic ComfortCare, built with denser foam and more coils, is engineered to maintain its support profile for 8 to 10 years.
| Cost Metric | Sealy Hollycourt | Restonic ComfortCare |
|---|---|---|
| Purchase Price (Queen) | ~$900 CAD | $1,619 CAD |
| Cost Per Coil | $1.13 | $0.92 |
| Expected Lifespan | 3-5 years | 8-10 years |
| Cost Per Year | $225/year | $125/year |
| White Glove Delivery | Not available | Included in service area |

Sealy Hollycourt vs. Restonic: Side-by-Side Testing
Our team invites every customer who mentions the Hollycourt to test a Restonic ComfortCare queen in the Mattress Miracle showroom. The differences become immediately obvious when you lie down:
- Pressure Relief: The 1,222 pocketed coils in the ComfortCare create a more precise cradle around shoulders and hips. The Hollycourt's 800 coils produce a broader, less targeted support feel
- Edge Support: Roll to the edge of the ComfortCare and the reinforced perimeter coils keep you supported. The Hollycourt's foam encasement compresses under body weight at the edge
- Motion Isolation: Partners report significantly less motion transfer on the ComfortCare due to the higher density of individually wrapped coils
- Temperature Regulation: More coils means more airflow channels between them. The ComfortCare sleeps noticeably cooler than the Hollycourt's tighter coil arrangement
Upgrade Path
If you want even more premium support, the Restonic Revive Reflections ET offers 1,200 coils in a flippable, dual-sided design at $2,395. It is the only flippable mattress in its price range, effectively giving you two mattresses in one.Who the Sealy Hollycourt Actually Suits
To be fair, the Hollycourt is not a bad mattress for everyone. It works reasonably well for:
- Guest rooms where the mattress sees occasional use
- Single sleepers under 150 lbs who do not need heavy-duty support
- Short-term housing where you plan to upgrade within 2 to 3 years
- Budget-conscious buyers who prioritize upfront cost over long-term value
However, if you are a primary sleeper looking for 7+ years of consistent support, share the bed with a partner, or weigh over 180 lbs, the Hollycourt's construction will likely disappoint you before the fifth year.
Frequently Asked Questions
Is the Sealy Hollycourt at Costco the same as the retail version?
No. The Costco Hollycourt is a warehouse-exclusive configuration with adjusted coil counts, foam densities, and cover materials to meet the Costco price point. The model number may be similar, but the internal construction differs from what you would find at a Sealy retail partner.
How many coils does the Sealy Hollycourt queen have?
The Costco version of the Sealy Hollycourt queen contains approximately 800 Sealy Response coils. By comparison, the Restonic ComfortCare queen at Mattress Miracle has 1,222 individually wrapped pocketed coils, providing 53% more support points.
Can I return the Sealy Hollycourt to Costco if I do not like it?
Yes, Costco Canada has a generous return policy on mattresses. However, returning a mattress is a significant hassle involving transport logistics, and many people continue sleeping on a mattress they are unhappy with rather than going through the return process. Testing before you buy at a showroom like Mattress Miracle eliminates this risk entirely.
How long does the Sealy Hollycourt Costco mattress last?
Based on the 2.5 lb foam density and 800 coil count, most sleepers report noticeable body impressions within 2 to 3 years of regular use. The Restonic ComfortCare with 3.0+ lb foam and 1,222 coils maintains its support profile for 8 to 10 years under normal conditions.
Is the Restonic ComfortCare worth the extra cost over the Hollycourt?
At approximately $225 more than the Hollycourt, the ComfortCare delivers 53% more coils, higher density foam, and significantly longer lifespan. The cost per year of ownership is actually lower at $125 per year versus $225 per year for the Hollycourt. Visit Mattress Miracle at 441 1/2 West Street in Brantford to test both and feel the difference. Call (519) 770-0001.
Does Mattress Miracle offer delivery like Costco?
Mattress Miracle offers white glove delivery throughout southern Ontario, including Hamilton, Burlington, Mississauga, Toronto, Kitchener, Waterloo, Guelph, Cambridge, St. Catharines, Niagara Falls, London, Barrie, and Oshawa. Unlike Costco's doorstep drop-off, white glove service includes in-home setup and old mattress removal.
Final Verdict: Test Before You Buy
The Sealy Hollycourt at Costco is a recognizable name at a warehouse price. But when you look past the brand label and examine the actual construction, the 800-coil, 2.5 lb foam build does not compete with what specialty retailers offer in the same price range. The Restonic ComfortCare at Mattress Miracle gives you 53% more coils, denser foam, better edge support, and a mattress built to last twice as long.
