15 Things to Know Before Buying a Mattress From Costco (Complete Guide)

The importance of a good night’s sleep cannot be overstated; quality rest is essential to good human function. It all starts with your mattress, and if your interest has been piqued by Costco’s selection, you aren’t alone; the mega-retailer has something for everyone.

However, before you go wading into the mattress pool, make sure you’re an informed shopper. Here are 15 things to know before buying a mattress from Costco!

15 Things to Know Before Buying a Mattress From Costco In 2024

1. If You’re Buying a Mattress From Costco, You Have Many Types to Shop

One of the things that amaze me about Costco’s mattress selection is how many options they offer. To start off, you can choose from Innerspring, Hybrid, Memory Foam, and Adjustable mattresses.

Innerspring is your typical spring-based mattresses, with metal coils within to provide support. Hybrids contain both coil springs with layers of memory foam on top.

The memory foam layers provide great support, while the more cost-efficient coil springs keep the entire mattress more affordable than full memory foam.

Memory foam mattresses were made famous by the Sealy Posturepedic commercials with a glass of wine on one side and a jumping woman on the other.

Finally, adjustable mattresses are used on mechanized bed frames where the left and right sides can be moved independently.

2. Don’t Go Looking Too Hard for a Mattress From Costco Under the Kirkland Signature Label

While Costco sells a panoply of items under the Kirkland Signature label (vodka, apparel, and many different types of foods), the company only sells one Kirkland Signature mattress.

Further, that mattress reveals the manufacturer right in its name: “Kirkland Signature by Stearns and Foster.” Perhaps, on the whole, none of the other mattress manufacturers who were willing to partner met Costco’s extremely high standards.

3. Instead, You Will Find These Brands When Shopping for a Mattress From Costco

Rather than a huge selection of Kirkland Signature mattresses, you can find these mattress brands at Costco:

  • Sealy
  • NovaForm
  • Sleep Science
  • Beautyrest
  • Brentwood Home
  • Comfort Tech
  • GhostBed
  • Tempur-Pedic
  • Molecule
  • Casper
  • Zinus
  • Cocoon
  • Simmons
  • Drexel Heritage
  • Leesa

4. A Mattress From Costco Will Likely Save You Hundreds

Despite the big names, you won’t see the biggest prices at Costco. Remember: the company doesn’t mark up anything more than about 14 percent in-stores.

The Sealy Response Premium RidgeCrest 14” mattress costs $999.99 for a king-size, while the same one on Amazon retails for about $1,600!

The cheapest Sealy hybrid mattress at Ashley Furniture costs at least $799 for a queen, but you can find one at Costco for $500.

5. A Mattress From Costco Might Not Be the Best Deal

Still, that doesn’t mean you will always get the very best price at Costco. If you shop around, you might find the same or comparable mattresses for less at furniture stores (when they’re running sales) or different online vendors.

For example, Wayfair sells a 14” hybrid mattress for $400 (for a queen), with free shipping that is often very fast.

The mattress is high-quality, comparable to a brand name, but cheaper even than Costco.

If you’re looking for a great price on a good mattress, Costco is definitely an option, but if you want the very best price, you should still shop around a bit.

6. Not Every Mattress From Costco Requires You to Be a Member to Purchase

There are some mattresses from Costco that are clearly marked with a “C” icon next to the name and the words “Member Only Item.”

That means they’re available for purchase only to Costco club members.

If a mattress doesn’t carry that icon, then anyone can purchase them online and have them shipped to their home, member or not.

7. You Can Get Your Mattress From Costco Shipped

As I just mentioned, you don’t have to live within proximity to a Costco warehouse store to receive a mattress from the company.

Costco offers delivery service, free for many items, via UPS, FedEx, or USPS.

Since mattresses are pretty heavy and bulky, USPS likely won’t be handling your delivery.

UPS and FedEx are better equipped to handle heavier parcels.

8. You Might Also Add on White Glove Delivery for Your Mattress From Costco

8. You Might Also Add on White Glove Delivery for Your Mattress From Costco

Costco offers both “Room of Choice” delivery and “White Glove” delivery for bulkier shipments.

The former means that the delivery person will take the mattress to the specific room, even if it’s up three flights of stairs.

The White Glove delivery means the delivery person will not only deposit it in the room, but they will also unpack it and inspect it before leaving, to ensure it’s just what you ordered.

Next, they’ll take the packaging with them for disposal, so you don’t have to worry about it.

9. Every Mattress From Costco Carries a Money-Back Warranty

One of the finest points about shopping at Costco is the generous money-back guarantee (this also extends to any of the mattresses that the company sells).

According to SleepAim, while other mattress retailers usually cut off returns after a few months, Costco’s policy is pretty much forever.

So, if you’re unhappy with your purchase for any reason (even if you don’t like the color), initiate a return and Costco will give you your money back.

10. You Have Forever to Change Your Mind About the Mattress From Costco

Even better than getting your money back within a set amount of time, Costco doesn’t put a limit on when you can return the mattress and get your money back.

That’s fortunate because many issues with mattresses can take some time to develop.

While you can’t return the mattress because you spilled something on it and want a new one, issues with quality, like sudden, severe sagging, are a returnable offense.

11. You Don’t Necessarily Need a Receipt to Return Your Mattress From Costco

While conducting a mattress return to Costco with a receipt is the most ideal situation, Costco is very generous with its policy and doesn’t necessarily require it.

That said, the company doesn’t legally owe you your money back without a receipt.

Therefore, if you don’t have one (and the cashier can’t find the record of your purchase), it’s best to take the loss graciously.

12. Your Mattress From Costco is Likely Not Going to Be Organic

While Costco has many mattress options, like coil springs, hybrids, and more, one mattress type you won’t see a lot of are organics.

If you value organic materials in your life and would prefer them in your mattress, then you will likely have to shop elsewhere to find a product that fits your needs.

13. There are Some Concerns to Consider When Buying a Mattress From Costco

TerryCralle.com highlights some other concerns for shoppers who are looking to buy their mattress from Costco.

For example, returns are free only if you’re a Costco member. Those who aren’t members found customer service to be “inconsistent” and difficult to navigate.

As well, the very popular Casper brand is one of the mattress types that can only be purchased by Costco members (if you run the numbers and find that you’ll save more than $60 on a Casper model, the membership has paid for itself).

14. The Company Really Wants You to Be Satisfied With Your Mattress From Costco – Even After Years!

A comment from Reddit told the story of how this user and their wife purchased a mattress from Costco.

Eventually, the mattress sagged on each side (where their bodies lay) and the middle section formed the “mountain range” that is common when people share a bed.

The shopper mentioned this at the customer service desk of their local Costco, whereupon the associate told them to bring the mattress back and receive a refund.

The kicker? They’d had the mattress for a few years. The refund was in the form of Costco credit because it had been so long, but they still got their money back!

15. When Shopping For a Mattress From Costco, You Can Also Pick up Accessories

Along with mattresses from Costco, you can also purchase accessories to make your rest even more enjoyable.

These include cooling pads, mattress pads and toppers, sheets, comforters/duvets, and much more.

To know more, you can also see our posts on Costco mattress returns policy, does Costco deliver mattresses, and Costco returns without a receipt policy.


Costco might not be the first store that comes to mind when you’re buying a new mattress, but the low mark-up policy to which the company adheres makes the retailer an affordable choice.

They have many different options for shoppers to choose from, but be aware that Costco doesn’t always have the cheapest prices.

Shop around, but don’t be surprised if you end up going with a Costco find!
