Best Costco Mattresses in Canada (2026): Picks by Need, Prices and the Return Policy

Which mattress brands does Costco sell in Canada?

Costco.ca's queen mattress category showed 88 results on October 4, 2026. We read 87 distinct listings: 77 mattresses or mattress sets, 8 RV mattresses and 2 other items (a foundation and a mattress sold with an adjustable base). The 77 carried 18 brand names.

Two things stand out. First, most of the range comes from long-established spring mattress makers, sold as a mattress alone or as a set with a foundation. Second, a few online-first names appear too, such as GhostBed, Novaform and Polysleep. If you are still deciding between foam and coils, our memory foam vs hybrid guide explains the difference before you compare models. Costco also publishes its own mattress buying guide, which covers sizes, sleeping positions and mattress types.

How much does a mattress cost at Costco?

Costco.ca shows most mattresses as a price range, because one listing covers several sizes and sometimes more than one firmness. On the four product pages we opened, the top of the range was the king price. Across the 77 listings on October 4, 2026:

• Middle of the range: half of the listings started at $889.99 or less.
• Promotions: 7 of the 77 listings carried a discount label that day, from "Up to $160 OFF" to "Up to $500 OFF". Costco's offers state their own start and end dates, so read the dates on the listing.
• Warehouse prices: product pages carry the note "Item may be available in your local warehouse, prices may vary", so the online price is not always the warehouse price.

To put these numbers next to the rest of the market, see our guides to how much to spend on a mattress in Canada and when mattresses go on sale.

Which Costco mattress is best for your need?

Each pick is a route to a decision with its basis and its trade-off, not a ranking and not a test result. The basis is what Costco.ca showed on October 4, 2026: the price range, the type named in the listing, and the number of member reviews shown beside it. Review counts were recorded for the first page of the category, the 23 listings Costco showed first.

• Best for the lowest price: Simmons 8 in. Gel Memory Foam, $249.99 to $389.99, with 1,828 member reviews shown. Falls short: at 8 inches it is among the thinnest mattresses in the category, better suited to a guest room, a child or a lighter adult.
• Best if you go by member reviews: Kirkland Signature by Stearns & Foster Lakeridge Luxury Medium-Firm Pillowtop, 4.5 stars from 3,895 reviews on its page, the most of any listing we recorded; queen $1,249.99 after $250 off. Falls short: queen and king only, 14.5 inches thick so it needs deep-pocket sheets, and the offer was dated to end October 4, 2026.
• Best low-priced hybrid: Contessa 12 in. Plush Top Pocket Coil Hybrid, $399.99 to $699.99, the lowest-priced listing with "Hybrid" in its name; the Beautyrest 14 in. Hybrid, $599.99 to $899.99, is the next step up in price. Falls short: we did not open these two pages, so check the specifications, the warranty and the reviews yourself.
• Best-reviewed Sealy under $1,700: Sealy Posturepedic Lincoln Heights 14 in., $1,199.99 to $1,699.99, with 2,790 member reviews shown and a choice of plush or firm. Falls short: its page offered Twin XL, queen and king only.
• Best for a memory foam feel: Novaform Advanced Back Support 12 in., $699.99 to $949.99, with 581 reviews shown. Falls short: an all-foam mattress has less bounce than one with coils.
• Best if you want latex: the NSC Medical listings were the only ones with latex in the name, from $1,199.99 for the 12 in. Hybrid Articulating System Latex to $2,799.99 for the 11 in. Natural Elements Latex. Falls short: a higher price band, and fewer listings to compare.
• Best if budget is not the limit: Tempur-Pedic Simplicity 11 in., $2,379.99 to $3,899.99 in Firm or Medium, the highest-priced mattress listings in the category. Falls short: the price; and at 11 inches, paying more does not buy more height.

A high review count shows that many members bought and rated a mattress; it does not tell you how it will feel to you. That is why the return terms below matter as much as the pick.

What are the Kirkland Signature mattresses?

Costco's house brand appeared on two listings, both named "Kirkland Signature by Stearns & Foster Lakeridge": a Luxury Medium-Firm Pillowtop and a Firm Tight Top, each sold in queen and king only. We opened the Pillowtop's page on October 4, 2026:

• Price: queen $1,249.99 after $250 off, shown against $1,499.99, with the offer stated as valid for orders placed September 28 to October 4, 2026. The listing's range ran to $1,999.99.
• Size and weight: the specifications gave a thickness of 36.83 cm (14.5 in.) and a queen weight of 57.61 kg (127 lb).
• Construction: "Mattress Composition" was given as innerspring, with gel foam and memory foam named among the features.
• A detail to check: the name says Medium-Firm, while the "Firmness" line in the specifications said Firm. The page also gave a delivery time frame of 10 to 15 business days while showing a "Quick Ship" label and an earliest delivery date three days out for a Toronto postal code. Confirm both at checkout.
• Reviews and guarantee: the page showed 4.5 stars from 3,895 member reviews, and the line "If you're not completely satisfied with this Kirkland Signature product, your money will be refunded."

The Firm Tight Top was listed at $1,399.99 to $1,699.99, with $1,699.99 shown for the king.

What is Costco's mattress return policy?

Costco Canada's Return Policy FAQs, read on October 4, 2026, say Costco guarantees satisfaction on merchandise and will refund the purchase price, with a list of exceptions. That list covers items such as electronics (90 days), diamonds, cigarettes and alcohol, tires and batteries, custom installations and gift cards. Mattresses are not named in it. What the policy does and does not say matters more than the headline:

• No number of nights: under "Is there a time limit for returning an item?", Costco gives no period for general merchandise. It says all returns are "reviewed and considered on a case-by-case basis" and that some will be authorized or refused at a manager's discretion.
• Large items: for a big-ticket item that needs special transport, Costco asks you to contact your local warehouse before you bring it in.
• Online orders: a Costco.ca order can be returned to any warehouse, and packaging is not required for a warehouse return. If a carrier picks the item up, the refund goes back to the original payment method.
• No receipt: a return may be accepted if the item can be verified as a Costco product, at the warehouse manager's discretion.
• The "90-day returns" label: on October 4, 2026, Google's search listing for Costco.ca's mattress pages displayed "90-day returns". Costco's own policy page gives 90 days only for the electronics it lists, and states no period for mattresses, so rely on Costco's page and your warehouse, not the search label.
• Future changes: Costco says it may restrict the policy for other products in future, and that restrictions are shown at the point of purchase.

In practice this is a satisfaction guarantee, not a sleep trial with a set length and a written process. Our sleep trial and return policy guide sets out how the written trials of Canadian mattress brands compare.

How does Costco deliver a mattress, and will it take the old one?

Delivery depends on the listing, so read the "Shipping & Returns" section of the exact mattress. On the Kirkland Signature Pillowtop page on October 4, 2026:

• Delivery included: "White Glove Delivery Included", with basic installation listed as included.
• Old mattress: "White Glove with Haul Away" was offered for $75.00 at checkout on that page; another listing we opened showed $79.99.
• Scheduling: you book the date through a link sent after shipping, and delivery must be scheduled within 30 days of that email or the order may be cancelled and refunded.
• On the day: deliveries run Monday to Friday between 8 a.m. and 7 p.m. (this may vary by region), a three-hour window is given the evening before, and someone aged 18 or over must sign.
• Restrictions: the page said the item is subject to some delivery restrictions and that you should check your postal code at checkout.

Not every Costco mattress ships this way. Some listings are marked "Online Only" and shipping terms differ by item, so check the listing. If you are not using haul away, our guide to disposing of or recycling an old mattress in Canada covers the options.

Do you need a Costco membership to buy a mattress?

Costco's membership page listed two personal memberships on October 4, 2026: $65 and $130 (Executive), each plus applicable sales tax, with "Shop Online and in Warehouses" among the benefits. The Executive membership adds an annual 2% reward on most Costco purchases, up to a stated maximum. Costco also says it will refund the membership fee in full if you are dissatisfied.

If you do not already hold a membership, add its cost to the mattress price when you compare. We did not test ordering a mattress without a membership, so confirm the current rule with Costco before relying on it. For returns, Costco says a non-member can return a gift only with the original receipt; without it, only the purchasing member can.

Costco or an online mattress brand: which suits you?

The two routes differ less on price than on how you decide and what happens if you choose wrong.

• Choice: Costco.ca listed 77 mattresses under 18 brand names in queen alone. An online mattress brand usually sells a handful of models.
• Trying it: Costco.ca says an item may be available in your local warehouse, but most of these listings are bought from a product page, as with an online brand, so the real test happens at home. See mattress in a box vs in store.
• Returns: Costco gives a satisfaction guarantee with no stated number of nights and case-by-case review. The Canadian online brands we read on September 25, 2026 gave written trials of 100 to 365 nights, most with a minimum number of nights before a return can start.
• Warranty: at Costco the warranty comes from each mattress maker, so it varies by listing. Read the warranty on the product page, not just the brand name.
• Price changes: Costco's Customer Service home page describes a price adjustment for Costco.ca orders when an item you bought recently drops in price; check the current terms there. Online brands rarely offer this outside a sale.
• Cost of entry: a Costco membership is $65 or $130 a year plus tax; online brands have no membership fee.

What should you check before you order a mattress from Costco?

1. The price of your size. Select the size on the product page; the range on the category page is not the queen price.
2. The offer dates. Discounts state a start and an end date.
3. Mattress alone or set. Many listings read "Mattress or Set". If you have a platform bed you may not need the foundation; our guide to whether you need a box spring explains when you do.
4. Thickness. Listings ran from 8 to 15 inches. A 14 or 15 inch mattress needs deep-pocket sheets and sits high on a tall frame.
5. Firmness in the specifications. Compare it with the name, as on the Kirkland Signature example above.
6. Delivery type, haul away fee and time frame for your postal code.
7. The maker's warranty and who handles a claim.
8. How you would return it. A full-size mattress does not go back in its packaging, so ask your warehouse how a return would work before you need one.
