Why are Costco Mattresses So Cheap?
Costco mattresses are often more affordable than those found at other retailers for several reasons:
Bulk purchasing: Costco operates on a warehouse model, which means they buy products in large quantities directly from manufacturers. This allows them to negotiate better prices and pass on the savings to their customers.
Membership fees: Costco is a membership-based retailer, which means customers pay an annual fee to access their products and services. These fees provide Costco with a steady revenue stream, enabling them to offer lower prices on their products, including mattresses.
Limited selection: Costco typically carries a more limited selection of products compared to traditional mattress retailers. By offering fewer options, they can focus on high-quality, popular models and negotiate better deals with manufacturers.
Lower overhead costs: Costco’s warehouse-style stores have lower overhead costs compared to traditional retail stores. They require less expensive fixtures and displays, and the simple, no-frills shopping environment allows Costco to save on expenses, which in turn results in lower prices for customers.
Private label offerings: Costco also sells their own private label mattresses, such as the Kirkland Signature line. These mattresses are manufactured by well-known brands but sold under Costco’s label, often at a lower price than their branded counterparts.
Overall, Costco’s business model allows them to offer quality mattresses at more affordable prices by focusing on bulk purchasing, reducing overhead costs, and leveraging membership fees to provide value to their customers.
How Many Mattresses Does Costco Sell A Year?
Since Costco is a large multinational corporation with a wide range of products, they typically do not release specific sales figures for individual product categories like mattresses.
However, it’s safe to assume that Costco sells a significant number of mattresses each year due to their competitive prices, vast customer base, and reputation for offering quality products.
Costco Mattress Trial and Warranty
Costco is known for having a very generous return policy. They offer a satisfaction guarantee on all their products, including mattresses, which allows customers to return items for any reason within a certain time frame for a full refund.
The specifics of the return policy vary depending on the product, but in general, most items can be returned within 90 days of purchase. Costco also offers a 100% satisfaction guarantee on their Kirkland Signature private label products, which means that if you’re not satisfied with one of their products at any time, you can return it for a full refund or exchange.
This lenient return policy has helped build a reputation for Costco as a company that values customer satisfaction and is willing to stand behind the products they sell. It has also contributed to the company’s success, as many customers feel comfortable making purchases at Costco knowing that they can easily return them if they’re not satisfied.
Costco offers a satisfaction guarantee on their mattresses, which means that you can return the mattress for any reason within the specified trial period for a full refund. The trial period varies depending on the mattress you purchase, but it is typically around 90 days.
In terms of warranty, most Costco mattresses come with a manufacturer’s warranty that covers defects in materials and workmanship. The length of the warranty varies depending on the mattress, but it is typically between 10 and 20 years. If you encounter any issues with your mattress within the warranty period, you can contact the manufacturer directly to make a claim.
It’s important to note that the warranty and trial periods may differ for specific models or brands of mattresses sold at Costco, so it’s always a good idea to read the product information carefully before making a purchase. Additionally, be sure to keep your receipt and any other documentation related to your purchase in case you need to make a warranty claim in the future.
Costco mattress delivery and removal
Delivery, setup and haul-away terms can vary by mattress, ZIP code and whether you buy online or in a warehouse. Check the product page and checkout details for the exact service level before ordering. Large-item returns can also follow a different process than a warehouse return.
Before buying, confirm four things: where the mattress will be delivered, whether setup is included, whether your old mattress can be removed, and how a return would be collected. See our Costco mattress return-policy guide for the practical steps.
Costco Mattress Quality
Costco offers a range of mattresses from different brands, and the quality of these mattresses can vary depending on the specific brand and model. However, in general, many of the mattresses sold at Costco are known for their high quality and competitive pricing.
Costco’s private label brand, Kirkland Signature, offers a variety of mattresses that are highly rated by customers for their comfort and durability. These mattresses are often manufactured by well-known brands, but sold under the Kirkland Signature label, which allows Costco to offer them at a lower price than other retailers.
In addition to Kirkland Signature mattresses, Costco also carries mattresses from other well-known brands, such as Sealy, Stearns & Foster, and Tempur-Pedic. These brands are known for their high-quality materials and advanced technologies, and many of their mattresses have received positive reviews from customers.
Overall, while the quality of Costco mattresses can vary depending on the specific brand and model, many customers have found that they offer a great value for the price and are comparable in quality to other store brands.
Which Costco mattress is best for your sleep position?
- Side sleepers: prioritize a pressure-relieving comfort layer and enough give at the shoulder and hip. Avoid choosing only by brand name—firmness can differ significantly between models.
- Back sleepers: look for medium to medium-firm support that keeps the pelvis level without creating a hard pressure point.
- Stomach sleepers: favor a firmer, more supportive build that limits hip sinkage.
- Combination sleepers: responsive hybrids are generally easier to move on than slow, deeply contouring foams.
- Hot sleepers: consider hybrids or more breathable comfort materials, but remember that “cooling” claims do not guarantee a cool night.
Costco inventory and model names change, so verify the current specification sheet rather than relying on an older price or discontinued model. If you want to compare measured scores and policies across brands, use the Yawnder mattress comparison tool.
Does Costco Carry Box Springs?
Yes, Costco does carry box springs for mattresses. They offer a variety of box spring options, including traditional box springs, low-profile box springs, and split box springs.
The prices and availability of box springs at Costco may vary depending on your location and the specific model you’re interested in. It’s a good idea to check the Costco website or your local Costco store to see what options are available in your area.
It’s important to note that not all mattresses require a box spring, and some modern mattress designs may work better with alternative types of support, such as platform beds or adjustable bases. It’s always a good idea to check with the manufacturer’s recommendations for the best support system for your specific mattress.
Adjustable bases at Costco
Costco periodically carries adjustable bases and mattress-and-base bundles, but selection varies. Confirm that the mattress is adjustable-base compatible, check the base warranty separately, and measure access through doors and stairways before delivery.
A bundle is not automatically the best value. Compare the mattress price, base price, setup, removal and return terms as separate line items before deciding.
When do Costco mattresses go on sale?
Costco discounts rotate by model and member offer rather than following one universal mattress markdown. Holiday windows can be useful, but the best time to buy is when the exact mattress you want is discounted and its delivery and return terms work for you.
We maintain a separate Costco mattress sale calendar so this buying guide does not go stale with temporary prices. Check Costco directly for today’s inventory and final member pricing.
