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
The Saatva’s coil-on-coil construction provides a classic innerspring feel. It’s a good option for combo sleepers, who will want to feel free to switch positions and avoid feeling “stuck” in the mattress. It comes in three firmness levels, so you should be able to find one that suits your needs. The white glove delivery Saatva provides is an added perk and will save you the headache of getting rid of your old mattress (they take it away for free!). For more information, watch our video review.
What our tester says:
“I think the Saatva is a great option for back sleepers, as the Luxury Firm model provides enough cushioning for their lumbar region, but also lots of support to keep their spine in a neutral alignment.” – Nichole Mondshein, lead reviewer and staff writer
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

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.

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 – WinkBed
The WinkBed is a luxury hybrid mattress. It has a similarly supportive and sturdy feel to a traditional innerspring mattress, but upgrades like a Euro top and cooling Tencel cover give it a touch of modern luxury. Available in three firmness levels, there is a WinkBed for just about every sleeper. And a responsive and bouncy feel makes it a great pick for combination sleepers. Learn more in our video review.
What our tester says:
“If you like the feel of a traditional innerspring mattress, the WinkBed could work for you. Since this bed offered great pressure relief around my lumbar region, I’d also recommend it to folks who suffer from lower back pain.” – Nichole Mondshein, lead reviewer and staff writer
The WinkBed mattress also offers superior pressure relief, but unlike the TEMPUR-Contour Supreme, the WinkBed is a hybrid mattress. So, it incorporates coils into its construction, offering an enhanced level of support that many memory foam mattresses lack. And with three firmness options, as well as the option to upgrade to the WinkBed Plus (a model for heavy people), the WinkBed brand offers adequate contouring for an array of body types and preferred sleeping positions. On our pressure map test, even the Luxury Firm version received fantastic results for comfort and pressure relief. This bed’s motion isolation also makes it an outstanding pick for couples and an exceptional mattress for the money.

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 is a softer hybrid mattress with memory foam and innerspring coils. It offers pressure relief, contouring, and solid support for many sleeper types, but especially back, side, and combination sleepers. For more information, check out our video review.
What our tester says:
“After testing out the Bear Star, I found it to be really cozy. I loved how plush the surface of the mattress felt as I was lying on it, but I still felt super supported. Lying on my back and my side, I felt comfortable and would definitely sleep on this at night in my own home.” – Amelia Jerden, senior staff writer
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.
If you think this bed could be the cure to your Goldilocks syndrome, check out our full Bear Star Hybrid mattress review.
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 – Nolah Evolution Mattress
The Nolah Evolution’s hybrid construction offers the cushioning of memory foam with the responsiveness of coils. The Luxury Firm model is a good option for side and back sleepers due to its medium-firm feel, though there are Plush and Firm versions as well. Those who share a bed may also appreciate its low motion transfer, so you won’t be disturbed by a partner’s movements and its solid edge support to allow you to maximize surface area. For more information, check out our video review.
What our tester says:
“I laid down to rest on this mattress on my back — my primary sleep position. I felt comfortable, but also appreciated the cozy, plush top of the bed. After some time lying on my back, I switched over to my side. I didn’t find this position quite as comfortable, as I did feel some slight pressure buildup in my shoulder.” – Amelia Jerden, senior staff writer
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.

Sealy Posturepedic – Best for Back Pain
Expert Opinion
If you suffer from back pain, 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 and keep your hips properly aligned with your shoulders 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 near the edge 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 – Saatva Rx Mattress
Designed specifically for sleepers with back pain and joint pain, the Saatva Rx features several layers that combine both foam and coils. This creates a blend of comfort and support throughout the entire mattress that’s cushioning enough for any aches and pains while still being sturdy enough for a neutral spinal alignment. Learn more in our Saatva Rx video review.
What our tester says:
“I found that this bed has a supportive feel that easily works for people of all weights, but still feels plush and comfortable.” – Amelia Jerden, senior staff writer
The Saatva Rx mattress is a sturdy, hybrid mattress designed to relieve joint and back pain with pressure-relieving foam and pocketed steel coils. It’s hard to beat Costco’s satisfaction guarantee, but Saatva has a year-long sleep trial period and a lifetime warranty. That said, the Saatva Rx is slightly more expensive than the Sealy Posturepedic after discounts. However, it has luxurious features, including five-star materials, zoned support, and a quilted organic cotton cover, and proves itself an excellent value mattress.

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 Brookyn Bedding Aurora Luxe mattress is one of Brooklyn Bedding’s more high-end mattresses. It’s got a ton of cooling features in it that can help hot sleepers sleep cool all night. It’s also available in three different firmnesses, so it can accommodate all of the sleeping positions. For more information, check out our video review.
What our tester says:
“First and foremost, I’d recommend this mattress to hot sleepers. This bed sleeps nice and cool thanks to special phase change technology and gel infusions. The Aurora Luxe is also a nice pick for back sleepers. This mattress in the Medium model is medium-soft, so it should contour the hips while also lifting them into alignment.” – Nichole Mondshein, lead reviewer and staff writer
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.

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 is somewhat surprising for an all-foam mattress; it’s fairly firm and is even supportive enough for stomach sleepers. Back sleepers should also be well-supported, and budget shoppers should appreciate its value price point. Learn more in our Siena video review.
What our tester says:
“The Siena has a simple, minimalistic design that gets the job done for stomach sleepers and a lot of back sleepers. I think it’s a great option for those after a firm mattress. It will keep sleepers propped up and slightly cushioned, which is especially a major win for stomach sleepers.” – Bridget Chapman, former senior product editor
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.
Is this bed right for you? Check out our full Siena mattress review.
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 Mattress 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 mattresses 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, except for 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 it 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.
If you’re a Canadian shopper, check out our Best Mattresses in Canada for our expert picks.
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.
Are Costco Mattresses Good Mattresses?
There are some great options for mattresses that can be found at Costco, and it may be a good option for shoppers looking for a budget-friendly bed. However, if you want a luxury mattress or something with more bells and whistles, a Costco mattress may not be exactly what you’re looking for.
How We Tested the Best Costco Mattresses
Firmness
Firmness is important to consider when purchasing any mattress, as it affects — to put it simply — how it feels when you lie down on it. While firm mattresses can still be pressure relieving, and softer mattresses can be supportive, firmer mattresses generally offer more support and promote more spinal alignment, and soft mattresses are usually more contouring. When buying a Costco mattress, considering how firm it is is an important first step of buying.
This is also important to consider depending on your sleeping style. We test all of the mattresses we review for their firmness level using our mattress firmness scale, which places mattresses from 1 to 10, with 10 being the most firm and 6.5 being medium firm. Our expert testers lay on each mattress in various sleeping positions and assign a firmness score to the mattress. We generally recommend that stomach sleepers look for a firmer mattress, side sleepers opt for something a bit softer, and back sleepers go for something in the middle.
Cooling
Cooling and temperature regulation are very important for almost every kind of sleeper, especially those who sleep hot or prefer a cool mattress. When looking for cooling mattresses from Costco, or testing the cooling capacity of Costco mattresses, we first examine the materials and look for features like breathable coils, gel-infused foams, or breathable materials such as cotton or cooling covers. We then use our thermal gun to test the mattress. We measure the temperature of a mattress before and after we have laid on it for several minutes. The temperature difference is a sign of how good the mattress is at cooling. We have found that anything below 10 degrees is good cooling and below 6 degrees is great cooling.
Pressure Relief
Pressure relief refers to the amount of pressure alleviated in a certain part of the body when lying on a mattress. This is important both for being comfortable on a bed, as well as for pain alleviation and prevention. Your sleeping position matters here, as different positions need pressure relief in different areas. Back sleepers generally need relief across the lumbar region and sometimes the neck or hips, stomach sleepers need relief in their hips and sometimes shoulders, and side sleepers should look for pressure relief in the shoulders and hips.
To measure pressure relief in the best Costco mattress, we use a specialized mat, which we roll across the bed and lay on. The mat then uses thermal imaging to measure the areas where pressure is relieved, creating a digital pressure reading called a pressure map. As you can see, red and orange indicate poor pressure relief, whereas green and blue indicate better or good pressure relief.
Sleeping Position
As we mentioned, sleeping position is very important when considering what Costco mattress is best for you. How you sleep affects what firmness is best, how much pressure relief you need and where, and also what kind of mattress is going to be the most comfortable for you. We consider sleeping positions in every mattress by laying on the beds in various sleeping positions and seeing how we think that mattress would work for that kind of sleeper.
Side Sleepers
Side sleepers place the majority of their weight on their hips and shoulders. To avoid pressure building (and therefore pain), we recommend softer mattresses with plenty of cushioning and sinkage to allow those sensitive joints to be gently cradled.
Back Sleepers
When it comes to back sleeping, medium firm is the name of the game. These mattresses have enough cushioning to alleviate tension in the lower back while also being supportive and promoting proper spinal alignment.
Stomach Sleepers
Stomach sleepers typically need firm mattresses with minimal sinkage. These beds help keep the hips propped up and aligned with the shoulders. If the hips sink in too far, it causes the spine to bend into a U shape, which leads to lower back pain.
Combination Sleepers
Combination sleepers should look for responsive mattresses with plenty of bounce. This feature allows the sleeper to switch between sleeping positions without feeling trapped in the mattress’s layers. If you’re a combination sleeper, consider which sleeping positions you most often sleep in and choose a mattress that’s compatible with both.
Mattress Materials
The materials of your mattress can affect how it feels, how durable it is, the price, and the other elements we have mentioned above, so it’s important to consider the material and construction of your Costco mattress. Below, we break down the materials of mattresses so you can have a better sense of what each is made of.
Latex
Latex mattresses are an excellent, eco-friendly choice for a mattress, and may also help reduce exposure to allergens such as dust. Natural latex is made from tree sap, meaning that it’s better for the environment than man-made materials, and also naturally allergen-repellant. Latex is comfortable while providing necessary support, and its porous material makes it very breathable. Latex is generally fairly bouncy, but not always very soft, so this may not be the best option if you’re looking for that hugging feel.
You can learn more about our favorite latex mattresses on our best latex mattress page.
Innerspring
Innerspring mattresses are made from two layers of coils, or springs, and a thinner layer of foam on the top of the mattress. Innersprings are one of the oldest mattress constructions, but they remain popular for their support and excellent cooling capabilities. The two layers of coils make the bed extremely breathable, so they’re a great choice for hot sleepers. The springs also provide good durability and strong edge support. These mattresses are not generally hugging, however, so they may not be ideal for someone looking for a traditionally soft mattress feel.
You can look at our favorite innerspring mattresses on our best innerspring mattress page.
Memory Foam
Memory foam is a distinct type of foam that’s slow-moving, contouring, and very comfortable for many sleepers. As the name implies, memory foam “remembers” your shape or the shape of something lying on the bed and maintains that shape for several minutes. Memory foam is a great option for sleepers who like to feel like they’re being hugged by their bed. This material is also known for providing a lot of contouring and pressure relief.
Check out our picks for the best memory foam mattresses to learn more.
Hybrid
Hybrid mattresses are made of one layer of foam and one layer of coils, or springs. Hybrid mattresses are very comfortable, can stay very cool because of their breathable springs, and are popular among many different types of sleepers. They come in various levels of firmness, meaning you can find the perfect level of softness for you.
One issue with hybrid mattresses is that they tend to be expensive, with most costing upwards of $1,000. However, you can always get a discount on our best hybrid mattresses page.
Body Weight
No two mattresses are exactly the same, and neither are any two sleepers. Along with your sleeping position and personal preferences, your body type can largely determine how a mattress feels and performs. When we test our mattresses, we always take body type into consideration to ensure every type of sleeper can find the right bed for them. Our team of Certified Sleep Science Coaches are familiar with how mattresses respond to different weight levels, and use this knowledge to make expert recommendations.
Heavier sleepers are likely to sink further into extra soft mattresses, and they may not find enough back, spine, and hip support from these beds. However, we have a list of the best mattresses for heavy sleepers, specially picked with these folks in mind. Likewise, we typically don’t recommend firm mattresses to lightweight sleepers, as they’re not heavy enough to sink into the firm layers, and the bed might feel too firm. If you enjoy a very firm feel, then this shouldn’t be an issue, but it’s something to keep in mind if you’re looking for body contouring and sinkage.

Motion Isolation
If you sleep with a partner or pet, you may be familiar with sleep disturbance from their tossing and turning. A bed with low motion transfer is able to isolate movement on one side of the bed and prevent the sleeper on the other side from feeling it. All-foam beds are typically the best at isolating motion, while hybrid and innerspring mattresses with coils are springier and prone to higher motion transfer. We test motion isolation using three tests: a human test, a wine test, and a seismometer test.
The human test involves having someone move around on one side of the mattress and seeing if the person on the other side can detect their movement. Our wine test involves placing a glass of wine on one side of the mattress and seeing how much the liquid moves if someone tosses and turns on the other side. The last test, the seismometer test, involves dropping a 10-pound steel ball onto the mattress from gradually increasing heights and using a seismometer to measure the disturbance. Large lines on the graph indicate high motion transfer and therefore a chance of increased sleep disturbance. These tests help provide an accurate scope of how well a mattress can isolate motion, which helps us make recommendations for couples.
Edge Support
Edge support refers to how strong a mattress is along its perimeter. Ideally, a mattress will be just as strong and sturdy at the edges as it is in the very center. This is an appealing feature for anyone who likes to sit or lie near the edge of the bed or for people who want to spread out and use the entire surface of the mattress. Couples can also appreciate strong edge support because it can make the mattress feel larger. Edge support can indicate how durable a mattress is and whether it’s prone to sagging over time.
We test edge support by sitting and laying on the edge of the mattress and measuring how much it sinks under our weight. We also observe how stable we feel and whether we feel at risk of slipping off the bed. All-foam mattresses tend to have weaker edge support, while mattresses with coils or reinforced edges typically have stronger edge support.
Price
Mattresses are a major purchase — you’re buying a product you’ll sleep on for many years. Many shoppers want a mattress that’s high-quality while still being affordable. Luckily, Costco is known for selling great products at a reasonable price. They sell a variety of luxury brands, as well as some more basic options. Some mattresses are more expensive than others, but Costco frequently offers discounts for members and usually has big sales around the holidays. If you want the best bang for your buck, check out Costco’s online prices, as they are sometimes cheaper online than in-store.

How We Chose These Mattresses
Our team of Certified Sleep Science Coaches has reviewed more than 300 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.
