You can find virtually everything at a discount at Costco, from bulk groceries and home goods to furniture and electronics. This popular membership warehouse club is also a great place to find a good deal on a high-quality mattress. Costco carries its own label of mattresses alongside well-known national brands both online and in-store. If you aren’t a Costco member or prefer to buy your mattress directly from a retailer — we’ve rounded up some options for you, too. There’s something here for everyone in this list of the best Costco mattresses.

Kirkland Signature Lakeridge Mattress – Best Overall

Expert Opinion

Costco may not be the first place that comes to mind when you think of luxury mattresses, but the Kirkland Signature Lakeridge mattress may change that. This bed is a hybrid made with foam and coils, as well as premier features like a moisture-wicking Tencel cover and reinforced edge support for extra durability — but at a price tag at nearly half the cost of other luxury mattresses. The brand says that this mattress has a medium firmness level, which is comfortable for many sleeping positions and preferences.  

What Customers Say

Customers raved about the bed’s value and the comfortable blend of firmness and plush comfort that it offered. They also loved this bed’s edge support, stating that you can sleep on the entire surface of the mattress without worrying about slipping off the edge. 

Pros of the Kirkland Signature Lakeridge Mattress

• This mattress provides luxury on a budget. Mattresses with similar high-end features and cooling technology typically cost several hundred to thousands of dollars more than this budget-friendly mattress. 
• Customers with a wide variety of body types and sleeping preferences gave this bed five-star reviews, making it a versatile pick that suits most sleepers. 
• This bed provides great motion isolation, which is helpful for light sleepers or those who toss and turn at night. Sleepers can get in and out of bed without disturbing their partners, according to customer reviews. 

Cons of the Kirkland Signature Lakeridge Mattress

• Customers noted that the bed is heavy and hard to move around, so you may need to have extra hands around if you need to move your mattress. 
• This bed is only available online, so you can’t pick it up from a warehouse.

Kirkland Signature Lakeridge Mattress Alternative – Saatva Classic Mattress

Similar to the Kirkland Signature Lakeridge mattress, the Saatva Classic mattress is a luxury mattress built with innerspring coils and a plush Euro pillow top. Saatva uses materials like organic cotton and recycled steel, making this bed a good pick for eco-friendly shoppers. It comes in three firmness levels: Plush Soft, Luxury Firm, and Firm, and has a wide variety of size options from twin to split California king.

The Saatva Classic comes at a higher price point than the Kirkland Signature Lakeridge bed, but its price also includes white glove delivery. That means the brand will send someone to your home to set up the mattress for you. However, it’s worth noting that if you buy a Costco mattress online, they offer the same service.

Beautyrest Silver – Best Luxury

Expert Opinion

If you’re in the market for a top-of-the-line mattress, the Beautyrest Silver may be the bed for you. This bed is built with four layers of foam for a plush and decadent sleeping experience. The soft comfort of the top layers is balanced out with a gel-infused lumbar support layer and a bouncy base of innerspring coils to keep your spine propped up in a healthy posture as you sleep. These cozy layers come wrapped in a cooling cover designed to keep you comfortable on warmer nights. This mattress is offered in queen, king, and California king sizes, and all of them are available for under $1,000. 

What Customers Say

Customers were impressed by the pricepoint of this luxe mattress and say that the bed stayed cool to the touch overnight. 

Pros of the Beautyrest Silver Mattress

• Cooling technology keeps the bed at a comfortable temperature in all seasons. 
• This bed offers a complex construction with luxury features that don’t break the bank.  
• Customers note that this bed provides enough support for heavier body types.

Cons of the Beautyrest Silver Mattress

• This bed’s medium-firm firmness level may be too stiff for some sleepers, such as those who sleep on their side.
• Customers note that the bed takes a few weeks to break in. 

Beautyrest Silver Alternative – Helix Midnight

The Helix Midnight mattress is another luxury hybrid bed that you can buy online. Similar to the Beautyrest Silver, the Helix Midnight features a zoned support layer to support a healthy posture, but also has an extra pillow top layer to create an extra-plush sleeping surface (when testing it, we scored it at a 6 out of 10 on our mattress firmness scale). The Helix Midnight ships for free and has a 100-night sleep trial period, so you can break in your bed for a few months before you commit to your purchase.

Comfort Tech – Best Budget

Expert Opinion

Shopping on a budget doesn’t mean you have to sacrifice quality. The Comfort Tech mattress is made of CertiPUR-US certified foams, meaning that they meet rigorous standards for durability and are free of ozone depleters and other emissions. This all-foam bed was designed for lasting support and durability, according to the brand. The mattress also comes wrapped in moisture-wicking soft knit cover to help keep you dry and cool as you sleep. The Comfort Tech also comes in two firmness levels — Medium and Firm — and is available in twin, twin XL, full, queen, king, and California king sizes. 

What Customers Say

Customers liked that the bed provided soft cushioning comfort while responding to your movements. They said that the foam allows you to move easily without feeling stuck in the bed. 

Pros of the Comfort Tech Mattress

• The foam layers of the Comfort Tech mattress are built with air pockets for added breathability. 
• Twin and full size options are great for smaller bedrooms, guest bedrooms, or kids’ bedrooms. 
• This bed’s foam layers relieve pressure from sleepers’ backs and joints, according to customer reviews. 

Cons of the Comfort Tech Mattress

• Innerspring mattress fans may not like the soft feeling of this all-foam bed. Plus, it may not work for those who need a firmer bed, like stomach sleepers.
• The Comfort Tech mattress provides less edge support than other beds in this round up. 

Comfort Tech Mattress Alternative – Siena Mattress

The Siena mattress is another wallet-friendly all-foam bed option. This medium-firm mattress provides a sturdy level of support coupled with a thick plush cover that provides light cushioning. This combination especially suits stomach and back sleepers. Our testing also showed that this bed has strong edge support for a memory foam mattress, making it a good pick if you like to sleep near the end of the bed.

TEMPUR-Contour Supreme – Best for Pressure Relief

Expert Opinion

The TEMPUR-Contour is made of TEMPUR’s uniquely formulated foam, which is beloved for its contouring and pressure-relieving feel. The brand says that the foam is designed to respond to your body’s shape and movement throughout the night, so you get contouring without feeling stuck in indentations. Customers note that this bed cradles the curves of their body while still providing enough support to prevent sinkage. The TEMPUR-Contour also features a removable cover that you can easily toss in the washing machine.

What Customers Say

Customers love how this mattress helps keep their back and shoulders in a healthy posture throughout the night and provides pain relief to tender areas. Reviews also note that this bed is firmer and cooler than typical foam mattresses.

Pros of the TEMPUR-Contour Supreme Mattress

• Customers loved that this bed’s soft foam layers isolated motion, so that they didn’t notice when their partners were moving around at night. 
• Buying a TEMPUR-Contour mattress at Costco allows you to get a brand-name mattress at a discount warehouse price. 
• Reviews stated that this bed provides pain relief for customers of all ages, including senior citizens. 

Cons of the TEMPUR-Contour Supreme Mattress

• Delivery time can take up to two to four weeks. 
• The TEMPUR-Contour is more pricey than other Costco mattress options.

TEMPUR-Contour Supreme Mattress Alternative – Puffy Cloud Mattress

The Puffy Cloud mattress also offers superior pressure relief. This bed is built with three foam layers, including a firm support layer that keeps your spine in a healthy posture, while the foams up top provide deep cushioning comfort around your pressure points. This bed’s motion isolation also makes it a great pick for couples.  An added perk: this mattress is cheaper than the TEMPUR-Contour bed, but also comes with a lifetime warranty from Puffy.

Leesa Legend Mattress – Best for Side Sleepers

Expert Opinion

The side-sleeping position can put extra stress on your hips and shoulders as you sleep. The best mattress for side sleepers provides extra cushioning around these tender areas without allowing your midsection to sink into the bed. The Leesa Legend is built with two layers of plush contouring foam to cradle your joints when you lay on your side, while the bed’s microcoil core keeps your spine propped up in a healthy posture. 

What Customers Say

Customers say that this bed helps them wake up pain-free in the side-sleeping position, but is also comfortable for back and stomach sleepers. They were also impressed by the quality and durability of the Leesa Legend mattress.

Pros of the Leesa Legend Mattress

• The Leesa Legend is built with luxurious materials like merino wool and organic cotton at a Costco price. 
• The bed’s soft layers provide relief to customers who suffered from back or joint pain, according to reviews. 
• Ventilation from the microcoil layer helps this foam bed sleep cool.

Cons of the Leesa Legend Mattress

• The Leesa Legend may not provide enough support for larger body types.
• The soft feel of the Leesa Legend means it isn’t a great pick for most stomach sleepers.

Leesa Legend Mattress Alternative – Bear Star Hybrid Mattress

The Bear Star Hybrid mattress is also built with a combination of plush foam and supportive coils, making it a good pick for side sleepers. The memory foam in the Bear Star Hybrid bed is infused with copper, which the brand says can help with muscle recovery and keep your body cool throughout the night. This mattress also comes at a similar price point to the Leesa Legend.

Sealy Posturepedic – Best for Back Sleepers

Expert Opinion

When you sleep on your back, you need a bed that will keep your spine in a healthy posture throughout the night. The Sealy Posturepedic could be a great pick for you. This hybrid mattress is built with a sturdy innerspring coil core that is designed to keep your back propped up with proper spinal alignment throughout the night. This mattress is also topped with a gel memory foam layer for extra comfort and reinforced edges to keep you supported even if you sleep towards the sides of the bed. 

What Customers Say

Reviewers were impressed by the Sealy Posturepedic’s sturdy edge support and how easy it was to set up.

Pros of the Sealy Posturepedic Mattress

• The gel-infused memory foam helps move heat away from your body to keep you cool.
• Sealy’s Duraflex Coil Edge system gives you extra support if you tend to toss and turn or like to sit on the edge of the mattress. 
• The Sealy Posturepedic is comfortable for combination and side sleepers, as well as back sleepers, according to reviews. 

Cons of the Sealy Posturepedic Mattress

• It may not be soft enough to those that prefer a memory foam feel.
• This mattress isn’t available in any size smaller than full.

Sealy Posturepedic Alternative – DreamCloud Mattress

The DreamCloud mattress also combines firm support to promote a healthy back with soft pressure relieving layers. It’s hard to beat Costco’s satisfaction guarantee, but DreamCloud has a year-long sleep trial period and lifetime warranty. The DreamCloud is slightly firmer and a little more pricey than the Sealy Posturepedic, but has luxurious features, including a cashmere quilted pillow top, that still make it a good value pick.

Novaform – Best Memory Foam

Expert Opinion

The Novaform is an all-foam bed that provides a supportive and cool sleeping experience, according to customer reviews. Memory foam mattresses have historically had a reputation for sleeping hot, but the Novaform is built with a Smart cooling cover and a comfort layer infused with gel beads to direct your body heat away from the bed. This mattress comes in Plush, Medium and Firm firmness level options to provide customizable levels of support for a wide range of body types and sleeping positions. 

What Customers Say

Customers note that this bed provides the deep contouring comfort that memory foam beds are known for without making them feel stuck in the bed or leaving indentations. Customers also loved the pressure relief that the Novaform provides for sore joints. 

Pros of the Novaform Mattress

• The Novaform provides a balance of a soft memory foam feel with firm support to help prevent aches and pains, according to customer reviews. 
• Foam beds can sleep hot, but reviewers say that the Novaform’s cooling technology keeps customers comfortably cool.  
• The Novaform’s responsive foam layers made it easy to move around and switch sleeping positions throughout the night. 

Cons of the Novaform Mattress

• The Novaform is not available in twin, twin XL or full sizes, so it may not be a great fit for those with smaller spaces.
• If you’re used to the bouncy feel of an innerspring bed, you may prefer a hybrid or innerspring coil mattress.

Novaform Mattress Alternative – Nectar Mattress

The Nectar mattress is another great option if you’re looking for an all-foam, budget-friendly bed-in-a-box mattress. The Nectar also has a gel memory foam layer to help keep you cool and provides motion isolation for restless sleepers. This bed is available in a wider variety of sizes than the Novaform, including twin, twin XL, and full sizes. The Nectar mattress is only available in one firmness level (we found it to be just softer than average). Additionally, it may not provide enough support for heavier body types.

Simply Modern – Best Hybrid

Expert Opinion

Hybrid mattresses — essentially beds made with more than one type of material — have a complex construction that typically makes them more expensive than mattresses made just of foam. The Simply Modern mattress is an exception that doesn’t sacrifice quality for a budget-friendly price. Built with three layers of foam and a support layer of innerspring coils, this bed provides the bouncy feel of an innerspring bed with plush memory foam pressure relief at a much lower price point than other leading national brands. 

What Customers Say

Customers say that this mattress performs just as well or better than more expensive name-brand mattresses. They also said that the top foam layer is soft and cozy, but kept them comfortably supported on top of the mattress without sinking. 

Pros of the Simply Modern Mattress

• The Simply Modern combines the best features of a responsive, cool innerspring bed with the pressure-relieving comfort of memory foam. 
• Priced at under $600 for a queen size mattress, this bed is one of the most wallet-friendly mattresses on our list. 
• The Simply Modern’s memory foam layers are CertiPUR-US certified and non-toxic. 

Cons of the Simply Modern Mattress

• Customers note that the bed doesn’t have the strongest edge support.
• The Simply Modern is only available in queen, king, and California king sizes.

Simply Modern Mattress Alternative – Novah Evolution Mattress

The Novah Evolution mattress is a hybrid mattress with two cooling comfort layers, including a comfort layer infused with graphite and a core base of innerspring coils. The Nolah Evolution mattress also includes a layer of high-resilience foam that mimics the supportive and bouncy feel of latex in the center of the bed. While this mattress has more features than the Simply Modern mattress, it is also significantly more expensive.

Sleep Science Bamboo Cool –– Best Cooling

Expert Opinion

Memory foam can tend to trap heat, but the Sleep Science Bamboo Cool mattress is formulated with cooling technology so you can cuddle up in an all foam bed while keeping night sweats at bay. The bed is topped with a layer of charcoal-infused memory foam that the brand says helps eliminate moisture and odor as you sleep. Underneath, there is a layer of foam infused with cooling gel beads to help move heat away from your body. 

The Sleep Science Bamboo Cool mattress also comes with a unique patented wedge-shaped edge support layer that the brand says both extends the life of your mattress and increases the sleep surface by 20 percent. All of these layers come wrapped in a hypoallergenic and antimicrobial washable cover to help stave off allergies. 

What Customers Say

Customers say that this mattress not only sleeps cool, but provides a soft memory foam feel with enough support to sleep with a healthy spine alignment throughout the night. Several reviewers were also impressed with the bed’s edge support. 

Pros of the Sleep Science Bamboo Cool Mattress

• The Sleep Science Bamboo Cloud Cool’s wedge support layer provides firm support across the entire surface of the mattress, according to reviewers. 
• Customers of all sleeping positions gave this mattress five-star reviews, saying it gave them an ideal level of comfort and support. 
• Many customers cite that they experienced minimal off-gassing when they unboxed their new mattress. 

Cons of the Sleep Science Bamboo Cool Mattress

• This bed is only available in queen, king, and California king sizes. 
• Sleepers who prefer a soft mattress may find this bed too firm, according to customer reviews. 

Sleep Science Bamboo Cool Alternative – Brooklyn Bedding Aurora Luxe Mattress

The Brooklyn Bedding Aurora Luxe mattress is a hybrid, bed-in-a-box mattress that has cooling technology integrated into every layer. The cover is made of a phase change material that is designed to move body heat away from the bed, and the bed uses copper and gel-infused foams to keep you cool while providing cushioning comfort. This bed has more customization options than the Sleep Science Bamboo Cool bed. It comes in three firmness levels, so you can choose the level of support you need, and comes in a pillow top or standard model. It comes in sizes ranging from twin to California king.

What to Consider When Buying a Costco Mattress

A mattress is a huge investment, both financially and in your sleep health. Here are a few factors to help you decide when you’re shopping for the best Costco mattress. 

Discounted Prices

Costco is a discount club that sells goods, including mattresses, at competitive prices. Even though Costco mattresses are normally sold at great prices, you may want to shop around online to see if there are better deals available before you commit. 

Limited Options

Costco only carries a few select mattress brands. If you aren’t finding the right mattress for you in one of their stores, keep in mind that there are many affordable options available online, including those alternatives listed in this roundup. 

Best Time to Buy a Costco Mattress

Costco offers discounts all year long, but you may get a better deal if you shop around holidays like Black Friday, Labor Day, and Memorial Day. 

Shopping Costco Online vs In Store

There are perks to shopping both online and in store at Costco. You’ll need a Costco membership to enter their warehouses, so that’s one factor to consider if you don’t already have a membership. 

There are some mattress models that non-members can purchase on the Costco website, but some of Costco’s online mattress offerings are for members only.  

If you go to the store, you can bring your mattress home that day and don’t have to wait for delivery service. Costco does not have a showroom where you can lay on the beds, but you can physically look at the different beds before you choose one. 

If you choose to shop online, you won’t have the same instant gratification. Your mattress could ship within a few days or take a few weeks depending on inventory and your location. One perk of shopping online, however, is Costco’s white glove delivery service. A delivery team will set up your new mattress in your bedroom and haul away your old bed as part of their delivery services. 

Costco Shipping and Delivery Policy

Costco provides free delivery and in-home setup with the purchase of your new mattress, with the exception of customers in Alaska and Hawaii, who may have to pay an additional shipping fee.

According to their policies, Costco will also haul away your old mattress, as long as your mattress isn’t dirty or contaminated. Costco is required to collect a small mattress recycling fee if the shipping address is located in California, Connecticut, or Rhode Island. 

Costco Mattress Return Policy

One of the benefits of shopping at Costco is their generous return policy. Costco has a 100 percent satisfaction guarantee, and mattresses do not have to be returned within a specific timeframe. If you bought your mattress in-person, you’ll need to physically bring it to a Costco warehouse. Online purchases can be returned online or at one of their stores. Once you return your mattress, you’ll get a refund of your whole purchase price. 

FAQs

Should I buy a mattress at Costco?

Costco can be a great place to start shopping for your new mattress. They carry a wide variety of mattresses with strong reviews, and have an outstanding flexible return policy. If you aren’t a Costco member, however, you won’t be able to shop in a warehouse and some of their mattress offerings won’t be available to you.

Can I return a mattress to Costco?

You can return a mattress to Costco for a full refund at any time.

Does Costco have mattresses in store?

Most Costco warehouses have a selection of mattresses in store, but some mattress options are only available online.

Are Costco mattresses good?

Costco carries a wide selection of mattresses that have received strong reviews from customers and third parties.

Will Costco take away my old mattress?

Costco will take away your old mattress at no extra cost, as long as the mattress isn’t dirty or contaminated. If your shipping address is located in California, Connecticut or Rhode Island, Costco is required to collect a small mattress recycling fee.

Do I need a Costco membership to buy a mattress?

You can buy some Costco mattresses online without a membership, but you’ll need a membership to shop in a warehouse. Some of Costco’s online offerings are also for members only.

How We Chose These Mattresses

Our team of Certified Sleep Science Coaches has reviewed more than 220 products in our mattress lab, running each one through tests such as pressure-mapping and measuring motion transfer with a seismometer. From there, we give every bed an overall score based on materials, comfort, support, cooling, and edge support. We also factor in brand performance with categories such as value and warranty.

To select these best Costco mattresses, we analyzed customer reviews to assess which are the best beds the discount retailer offers. We made our alternative selections by choosing similar mattresses we’ve tested to provide another option for those seeking an affordable mattress. Click here to learn more about our methodology.
