Our Rankings
Edge support and motion isolation are factored into our overall mattress ratings. These scores are shown in green (scores of 5.0+), yellow (3.0–4.9), or red (2.9 and below). Firmness, bounce, and cooling features are a matter of personal preference and aren’t part of our rating system, so these scores are shown in grey.

Product Details
The Sealy Hollycourt mattress stands 14.25″ tall and features a Euro-top construction. It has a medium-firm feel, making it suitable for all sleep styles. Hollycourt is only available in a queen size and costs $749.
Hollycourt has a layer of gel-infused convoluted foam to help keep you cool while you sleep and regulate temperatures throughout the night. A second layer of gel-infused foam is pre-compressed, which the Costco website says helps keep the foam more supportive for longer. However, some customer reviews mention their Hollycourt mattress sagging or forming divots soon after purchase.
The Hollycourt mattress cover is made with Sealy’s CleanProtect fabric. It seems to be a 100% polyester mattress cover treated to be antibacterial. Polyester is also water-repellant, but it isn’t an exceptionally breathable material. Like some Costco customers, you may find this mattress too hot, despite its cooling features.
In comparison, competitor brand Logan & Cove offers advanced cooling features like breathable latex-like foam and cooling nanofibres in the top cover. This helps regulate temperatures throughout the night. Competitively priced at $999 for a queen size, Logan & Cove Choice is available in a full range of sizes and is delivered straight to your door.

Delivery, Sleep Trial & Returns
Sealy Posturepedic Hollycourt is available at Costco both in-store and online, although product availability and pricing may differ by warehouse location. Shipping is free for online orders. You can, however, upgrade to White Glove with Haul Away service for an extra $75, and have your old mattress removed upon the new one’s delivery.
Your Sealy mattress should arrive on your doorstep in 7–10 business days, according to Costco’s website. Costco sometimes runs their “Quick Ship” promotion, under the premise that your mattress will arrive sooner. However, the website doesn’t specify how much faster this promotional shipping and delivery time is.
Sealy Hollycourt was delivered to us fully expanded. This could make it difficult to maneuver the mattress through your home into your desired room, and it also puts the mattress at a higher risk of being damaged during transport. Cuts or tears sustained during delivery won’t be covered by the warranty.
When purchasing a mattress through Costco, you won’t receive a sleep trial. Although Costco is known for its generous return policy, your return must still be approved in order to get your money back if the mattress isn’t a good fit for you. Costco will only provide return pickup if you ordered the mattress online. Otherwise, you’ll need to haul it back to the warehouse yourself.
The Sealy Posturepedic Hollycourt warranty is a 10-year limited manufacturer’s warranty. You’ll be covered for any premature divots, ripped handles, protruding springs, and other defects, as long as you use a proper mattress base and protect the mattress from spills or stains. Not following these terms will void your warranty. Sealy recommends using a mattress protector to help keep your warranty intact, although you won’t receive one with your purchase.
Despite its popularity, Costco is rated “Poor” on Trustpilot and “D-“ on Better Business Bureau. Sealy is rated “Poor” on Trustpilot, with a “B-” (unaccredited) BBB rating. In comparison, Logan & Cove‘s parent company is rated “A+” on BBB and “Excellent” on Trustpilot. Their mattresses come with a 365-night sleep trial, a 15-year warranty, and a free bedding bundle with your purchase, including a mattress protector.

Sealy Posturepedic Mattress Construction
The Sealy Posturepedic Hollycourt mattress is a 4-layer hybrid mattress assembled in Canada. It stands 14.25″ tall and includes layers of foam and individually pocketed coils.
- Layer 1: The first layer of this mattress is 1.25″ of Sealy’s convoluted GelBoost HD memory foam. This gel-infused foam offers a cooling effect and helps improve airflow throughout the mattress.
- Layer 2: This 3″ transition layer is SealySupport gel-HD foam—a second layer of gel-infused foam that is pre-compressed. This layer is CertiPUR-US® certified, but it’s not clear if this applies to all layers. This layer offers additional cushioning and prevents you from feeling the springs below.
- Layer 3: A 9″ inch layer of individually pocketed SealyResponse coils offers support and responsiveness, and is also meant to help reduce motion transfer.
- Layer 4: The final layer of this mattress is an unspecified fibre fill that measures 0.5″ when compressed beneath the coil layer (roughly 2″ when uncompressed, as seen in the photo above). The innerspring system rests on this layer, likely for stability and to prevent noise or scratches from the coils. The layer isn’t mentioned on Costco’s product page.
The remainder of this mattress’s height is made up of 0.5″ of fibre quilted into the Euro-top cover. These MoistureProtect fibres are described on Costco’s product page as being designed to draw moisture away from your body throughout the night.
Sealy Posturepedic Hollycourt’s cover is not removable or machine washable, so any stains or spills will need to be spot-cleaned. Any stains on the mattress will void your warranty, so Sealy suggests investing in a mattress protector. However, unlike competing brand Logan & Cove, the mattress doesn’t come with a mattress protector. You’ll need to purchase one yourself for an added cost.

MattressReviews.ca commissions licensed third-party engineers and uses public data to rate mattresses on over 40 criteria.
This allows us to accurately rate and compare the performance of the mattresses reviewed on this website. Engineer independence and operating standards help ensure their results remain unbiased, valid, and reliable. Each mattress was evaluated using the same strict mattress testing methodology to protect the overall integrity of the results. The full report has been given the official stamp of approval from an APEGA-certified engineer operating under a strict ethical code of conduct.
Mattress testing conducted outside of this professional standard poses a greater risk of validity errors or reviewer bias.
6.1 /10
Firmness
Sealy Posturepedic Hollycourt had a deflection of 3.5″ when laid on, which contributed to its firmness score of 6.1/10 when tested by third-party engineers. This places the mattress in the medium-firm range—a firmness typically well-suited for all sleepers.
However, some comments on Costco’s website mention that Hollycourt felt overly firm, and that the Euro-top cover was lumpy and uncomfortable.
7.3 /10
Edge Support
When tested for edge support, Sealy Hollycourt had a deflection of 4.8″. This resulted in a very good score of 7.3/10. You should feel supported while you sleep without having to worry about falling off the edges.
(Need a mattress with greater edge support? Consider Logan & Cove Choice with its higher score of 7.5/10.)
6.1 /10
Motion Isolation
Hybrid mattresses like Sealy Posturepedic Hollycourt use individually pocketed coils to help reduce motion transfer across their innerspring systems. Sealy performed just above average for motion isolation, earning a score of 6.1/10. Small movements from the other side of the bed will be muted, but you may feel larger disruptions, like a partner getting in and out of bed.
(If you’re a light sleeper, or uninterrupted sleep is important to you, you may prefer Logan & Cove and its much higher motion isolation score of 7.5/10.)
6.9 /10
Bounce
Bounce in mattresses is a preference. Lower bounce can mean a more even sleep surface, good for undisturbed sleep when paired with high motion isolation. A higher degree of bounce can make it easier to change positions while you sleep but can shake the mattress more.
Sealy Posturepedic Hollycourt had an above-average bounce score of 6.9/10. Considering the mattress’s mid-range motion isolation score, you may end up feeling more movements from a partner or pet across the bed.
4.7 /10
Cooling Features
Sealy Hollycourt is not advertised as a cooling mattress, but it does have a few features that promote cooling and breathability. This mattress earned points for its:
- Moisture-wicking fibres in the top cover designed to keep you dry and comfortable
- Convoluted memory foam for airflow and temperature control
- Gel-infused foam to help regulate body temperature
- Layer of breathable individually pocketed coils
At $749 for a queen size, Hollycourt offers some cooling features to help keep you cool. However, competitor mattresses like Logan & Cove feature CryoFusion™ nanofibres, breathable hollow fibre-fill, and gel-infused foam quilted into the cover. Choice also features a layer of cooling gel foam, and individually wrapped pocketed coils to help dispel excess heat from the mattress while you sleep.

Company Background
Founded in the 1880s, Sealy crafted customized mattresses in a Texas town, adopting the town’s name as its own. Sealy was an industry frontrunner by the 1920s. The well-known Posturepedic mattress line was added to the company in the early 1950s.
In 2012, Sealy merged with Tempur-Pedic, one of its biggest competitors, to become Tempur Sealy International, Inc. The corporation also owns the Stearns & Foster mattress brand.
Sealy holds a “B-” (unaccredited) rating on the Better Business Bureau, but a user score rating of only 1/5. On Trustpilot, Sealy has a “Poor” rating with a score of 2.3/5. Tempur-Sealy International also received a “Poor” rating on Trustpilot. Customers have reported issues receiving orders, using their products, and resolving warranty claims.
Frequently Asked Questions
Is Sealy a good mattress?
Sealy is a well-known mattress manufacturer and the creator of Posturepedic Technology™. However, numerous customers seem to be unsatisfied with their Sealy mattresses. Sealy is rated “Poor” on Trustpilot and “B-” (unaccredited) on the Better Business Bureau, with a customer review rating of just 1/5 stars.
Reviews on the Costco website mention that their Sealy Posturepedic Hollycourt wasn’t a comfortable firmness level, sagged and dipped prematurely, or came with delivery issues. The mattress also has only 47 reviews on the Costco website at the time this review was written.
If you’re looking for a mattress backed by more 5-star customer reviews, we think you should check out Logan & Cove. This Canadian-owned company has 4,500+ five-star reviews, is rated “Excellent” on Trustpilot, and is rated “A+” on BBB with 4.9/5 stars.
Are Costco Sealy mattresses good?
Sealy Posturepedic Hollycourt performed above-average in areas like edge support when tested by commissioned third-party engineers. On its own, Hollycourt is a reasonably good mattress. However, it’s available exclusively at Costco. While some sleepers are avid Costco fans, there can be disadvantages to buying a mattress from the retail giant.
Apart from needing a Costco membership to purchase a mattress, you also won’t receive a sleep trial. You’ll have to rely on Costco approving your return in case your Sealy isn’t the right fit. The mattress you receive will also likely not feel the same as the one you test out in the store in person, since the in-store mattress has already been broken in by other shoppers. Finally, if you purchased the mattress in-store and decide you’d like to return it, you’re responsible for transporting it back to the warehouse.
In comparison, companies like Logan & Cove offer a 365-night sleep trial, a 15-year warranty, and free delivery and return pickup. You also get a free bedding bundle with your purchase—something you won’t get from Costco.
Are Sealy and Serta the same company?
No, Sealy and Serta are separate companies. Sealy was founded in 1880 and merged with Tempur-Pedic in 2012 to become Tempur Sealy International, Inc. Tempur-Sealy owns the Sealy, Tempur-Pedic, and Stearns & Foster brands.
Serta is owned by Serta Simmons Bedding LLC. The parent company owns other mattress brands like Beautyrest, Simmons, and Tuft & Needle.
Can you flip a Sealy Posturepedic mattress?
No, you shouldn’t flip your Sealy mattress. Like most modern mattresses, Sealy Posturepedic Hollycourt is meant to be used one way only. Hybrid mattresses are often constructed with foam on the top and springs at the bottom. If you flip the mattress, you’ll be sleeping on top of the firm spring layer, causing discomfort and losing all the benefits of the plush top layer.
Do Sealy mattresses have fiberglass?
Sealy’s warranty outlines that their mattresses are not fire-proof, and therefore likely don’t have fiberglass. We also didn’t find any fiberglass when we cut open the mattress for this review, and it wasn’t listed on the law label. Mattresses made in Canada tend to not contain fiberglass because the federal government doesn’t have strict fire barrier requirements for mattress manufacturers.

Do Sealy mattresses need a box spring?
The Sealy Posturepedic Hollycourt mattress can be purchased with a box spring directly from Costco, but does not explicitly need to be used with a box spring. This mattress requires a foundation that has at least 5 equally spaced hardwood cross-slats, or a rigid bridge bar and 5 support legs. Any flat-surface foundation, such as a platform bed, would also be appropriate to use with Hollycourt.
Does Sealy make Stearns & Foster mattresses?
The Sealy brand is owned by parent company Tempur Sealy International, Inc., who also manufactures Stearns & Foster mattresses.
Does Sealy own Tempur-Pedic?
In 2012, the Sealy and Tempur-Pedic mattress brands merged to form Tempur Sealy International, Inc. The parent company now owns and operates both the Tempur-Pedic and Sealy brands.
How long do Sealy Posturepedic mattresses last?
Sealy Posturepedic Hollycourt’s warranty is 10 years, meaning you should reasonably be able to expect it to last about that long. Most mattresses last around 7–10 years with a supportive base and proper care, although some mattresses will last you even longer. However, some reviews on the Costco website mention the Hollycourt mattress sagging or creating divots after a short period of time, making it difficult to sleep comfortably on.

How long is the Sealy warranty?
The warranty on Sealy Posturepedic Hollycourt is a 10-year limited manufacturer’s warranty. In Hollycourt’s case, this warranty is provided through Costco. You’ll need to contact Costco in case of a warranty claim.
The Sealy warranty specifies their mattresses need to be used on quality foundations that provide “continuous support” and are found to be “adequate” by Sealy. In conjunction with proper handling and normal use, the frame “must have a rigid bridge-bar with at least 5 support legs or 5 equally spaced hardwood cross-slats with a supporting center leg” for a queen-size mattress or larger.
The warranty will cover ripped handles or protruding springs, but not superficial damage to your mattress, such as stains, burns, or a soiled cover.
What Sealy mattress alternatives should I consider?
We think you should consider Logan & Cove Choice as an alternative to Sealy Posturepedic Hollycourt. Logan & Cove makes their luxury-quality hybrid mattresses in Canada, for Canadians. Made with high-quality foams and individually pocketed steel coils, Choice performed very well for both motion isolation and edge support. It also has 4,500+ five-star reviews and comes with a 365-night sleep trial, a 15-year warranty, and free bedding bundle with purchase.
