Popular Costco Mattresses

Costco offers a wide variety of mattresses ranging from tri-fold and RV mattresses to standard foam and hybrid mattresses for bedrooms. Novaform, Stearns & Foster, GhostBed, and Casper are some of the most well-known brands you’re likely to find at your local Costco.

Novaform logo

In Canada, Novaform mattresses are available from Costco and Amazon. They’re generally available in queen and king sizes. Novaform says its foam is “proudly made in the USA, while most covers are imported.”

One of Novaform’s most popular mattresses is Novaform ComfortGrande Plus. This memory foam mattress is advertised as a cooling mattress, but some reviews on Costco’s website complain of heat trapping. This mattress was included in a 2023 product recall.

Stearns & Foster logo

Stearns & Foster is a luxury bedding brand based in Ohio, but manufactures several items in Canada. The Stearns & Foster brand is owned by Tempur-Sealy International, the world’s largest mattress manufacturing company.

Costco has an agreement with Stearns & Foster to produce Lakeridge, its Kirkland Signature mattress. The mattress is only available in queen and king sizes. Some Costco customer reviews report the mattress sagging after a short period of time.

GhostBed logo

Costco sells several GhostBed mattresses, including GhostBed Classic, a gel foam and aerated latex mattress. GhostBed advertises the Classic with a regular retail price of $2,495, but frequently has sales on its website. The mattress is significantly less expensive at Costco.

As a company, GhostBed is rated “Bad” on Trustpilot and “B-” (unaccredited) on BBB, based on a customer rating of 1.14/5 stars. Common complaints include false advertising, product quality, and difficulty getting the company to honour warranty claims.

Casper logo

Casper is well-known for being associated with the Target Corporation and celebrities like Ashton Kutcher. The American-based mattress maker sold a significant share of its Canadian assets to Sleep Country in 2023.

Costco offers two Casper mattresses: the Select memory foam and the Select hybrid. However, it’s hard to compare Casper Select with any other Casper mattress because it’s not listed on the Casper website. This makes it difficult to evaluate the mattress’s quality and make an informed buying decision.

 

Is Costco the best place to buy your next mattress?

Costco may have low prices and high convenience, but that doesn’t mean it’s a good place to buy a mattress. There are a few reasons why you should reconsider buying a mattress at Costco:

  • It’s hard to research mattresses. The Costco website offers limited information about details like mattress materials and construction, layer thickness, and foam density. Many Costco employees also won’t have answers to your questions about a specific mattress.
  • Mattresses aren’t always stored properly. Expanded mattresses should be laid flat for storage. However, Costco often stores fully expanded mattresses on their sides along the warehouse walls so customers can browse them more easily. This can damage the inside of a mattress over time and reduce its lifespan.
  • You may not get a freshly made mattress. If you’re buying a bed-in-a-box, there’s no guarantee that your mattress was recently made. It could have been inside the box for several weeks or even months. As a result, your mattress may not expand properly when you open the box. Some mattress warranties are also voided if the mattress is left inside the box for too long.
  • Prices and availability vary by location. There’s no guarantee that your local Costco will have the mattress you’re looking for. Even if they do have it, the store might not have your size, or might charge more for the same mattress compared to another warehouse.
  • Delivery and return pickup is only available for online purchases. If you find a mattress in-store and want to take it home, you need to transport it yourself. You’ll also have to bring the mattress back to the store if you decide to return it—no pickups.
  • Costco has a poor online reputation. The company is rated “D-” on Better Business Bureau and “Poor” on Trustpilot, based on thousands of customer reviews. A number of reviews complain of issues with delivery and customer service.
  • You need a paid Costco membership. You have to be a Costco member to purchase a mattress, whether you’re shopping in-store or online. This membership starts at $60/year, meaning you need to pay an added fee before you can buy a Costco mattress.

While it may seem smart to buy your mattress at the same place you get your groceries, there are other Canadian mattress brands that are well worth a look.

Douglas Original is a foam mattress available online at just $799 for a queen size. Only Douglas features impressive edge support and motion isolation, a 365-night sleep trial, and a 20-year warranty. The brand is rated “A+” on BBB and “Excellent” on Trustpilot. Your Douglas mattress also comes with a free bedding bundle—something you won’t get with a Costco mattress.

 

Frequently Asked Questions

Where can I try Costco mattresses?

Costco sells a small selection of mattresses in its warehouses. However, their mattress displays don’t encourage people to try out the mattresses before they buy. Most Costco mattresses are only available online, so you’ll have to wait for the mattress to arrive at your home before you can try it out.

Are Costco mattresses good?

Of the four mattress brands we tested and reviewed that are currently available at Costco, none earned an overall rating higher than 6.6/10. If you’re looking for a quality mattress, we recommend Douglas Original instead, which earned an overall rating of 9.9/10.

Douglas is our number-one pick for the best mattress in Canada. It offers superior motion isolation and edge support, a cooling top layer, a machine-washable mattress cover, and a medium-firm feel that’s ideal for any sleep position. Douglas has all the features you’re looking for at an unbeatable price of $799 for a queen size.

How much are Costco mattresses?

The price of a Costco queen mattress varies widely, from just a few hundred dollars to well over $3,000. It depends on the size, brand, and accessories you buy. You can expect to pay more for a king-size mattress, or if you buy a mattress with an adjustable base. In comparison, Douglas Original sells for just $799 for a queen size.

Does Costco deliver mattresses?

If you order a mattress online, Costco will deliver it to your door. You can also pay an extra $79.99 plus tax for them to remove your old mattress, as long as it’s not larger than your new mattress. However, if you buy a mattress in the warehouse, you’re responsible for transporting it home and setting it up yourself.

How do you return a mattress to Costco?

If you ordered your mattress online, contact Costco to start your return. They will arrange with you to pick up the mattress and issue a full refund. Customer reviews indicate that this process could take 2–3 weeks.

If you bought the mattress in the warehouse, wrap it in plastic and transport it back to the warehouse in person, where you’ll receive a refund. Costco also asks that the mattress be clean and in good condition.

Either way you shop, the Costco mattress return policy is known for being generous. There’s no time limit for returning items. But it’s always up to the retailer whether they’ll honour a return. You also might not want to take a chance on returning an item several years after you bought it.

Does Costco pick up mattress returns?

It depends. If you ordered your mattress online and want to return it, you can arrange for Costco to come and pick it up. But if you bought your mattress in the warehouse, you’ll have to return it to the warehouse yourself.

It’s worth noting that some mattresses can be heavy and hard to move. For example, a king-size Stearns & Foster Lakeridge mattress weighs 165 lb. This could be difficult to transport to the warehouse for a return.

Do Costco mattresses have fiberglass?

While fiberglass fire socks are common in mattresses produced in the United States, there’s no way to know for sure whether Costco mattresses contain fiberglass. However, there are some clues you can look out for:

  • Country of origin. If a mattress is made in the United States or China, there’s a good chance the mattress contains fiberglass.
  • Materials on the law label. Look for the word “fiberglass,” as well as “glass fibers,” “glass wool,” “glass-reinforced plastic,” “glass-fiber reinforced plastic,” or “fiberglass-reinforced plastic.”
  • Pricing. The cheaper the mattress, the more likely it contains a fiberglass fire sock as an inexpensive way to meet national fire regulation policies.

It’s possible that Novaform mattresses contain fiberglass, but we don’t know for certain. Novaform says its foam is “proudly made in the USA, while most covers are imported.” The website doesn’t state the cover’s country of origin. We noted that the ComfortGrande Plus model contains a fire sock—a fairly common safety feature, but one that could contain fibreglass.

In the past, Casper has stated that their mattresses contain fiberglass. This statement is no longer on Casper’s website. To be safe, double-check the law label if you purchase a Casper mattress from Costco.

It’s worth noting that Douglas Original—our top pick for Best Mattress Canada—is fully manufactured in Canada and doesn’t contain fibreglass.

What is Costco’s mattress warranty?

It’s surprisingly difficult to find a comprehensive Costco mattress warranty on the company’s website. The company does say it guarantees satisfaction with every product they sell. There are some exceptions, like electronics, products with a limited life expectancy, and custom installation services. But customers have been known to return items to Costco when they stop working, or even when they don’t like their items anymore.

Currently, Costco doesn’t have a stated time limit for returns. However, the company does state that it “may in the future restrict its return policy regarding these and other products.”

What is a good Costco mattress alternative?

The best mattress alternative to Costco is Douglas Original. (This mattress is also our number-one pick for the best mattress in Canada.) Douglas features a cooling gel layer, a machine-washable mattress cover, superior edge support and motion isolation, and pressure-point relief for all sleeping positions.

Douglas Original received top scores for its use of high-quality, eco-conscious materials, overall comfort, and excellent value at just $799 for a queen size. It comes with a 365-night sleep trial, 20-year warranty, and free bedding bundle with purchase.

The company is rated “Excellent” on Trustpilot and “A+” with the Better Business Bureau. Douglas has also earned over 13,000 five-star reviews from happy customers.
