Truth is, if you want to buy one of the best online mattresses you’ve got to do your research. Luckily for you, we’ve done it for you. We’re giving you the lowdown on the best online mattresses out there, all of which have been rubber-stamped for quality and comfort by customers and product experts alike.
Our experts have analyzed the data from a comprehensive compilation of online customer reviews to give you the scoop on the best mattresses available to buy over the internet.
The Nest Bedding brand tops our list of the 10 best online mattresses. While this premiere bed-in-a-box company offers several distinct mattress types, their best-selling model, the Exclusive Double Sided Hybrid bed, tops the list of favorites.
The Hybrid Visco Gel support foam and 13.75″ Caliber Coil system are exceptional. But it stands out thanks to its combination of pocketed support coils and copper-infused memory foam. This mattress offers two sides of firmness options just by flipping it over.
Made up of four layers, the mattress rounds off at a larger-than-usual 10 inches thick. The springs are individually wrapped, which means they are more effective at minimizing motion transfer and targeting pressure-point relief. Coils positioned around the perimeter also give the bed excellent edge support.
On top of the coil system, a series of high-performing foam layers infused with antimicrobial copper and cooling gels work together to create a mattress that provides optimum pressure-point relief, spinal alignment, and an overall superb sense of snugness. Even the oh-so-fluffy quilted cover is filled with cooling gel-infused memory foam, inspiring a more restful sleep.
Strengths We Love:
- With two firmness to choose from, it’s the kind of mattress that meets the needs of typical individuals. People who want more comfort prefers the medium side while those who like more support choose the firm side. Regardless of the side chosen, it’s an exceptional bed for getting better sleep.
- The cooling gel foam reduces the risk of the mattress running hot, a common issue with traditional memory foam. The typical customer experience is waking up with a refreshed feeling without the sweat, even in tropical conditions.
- The mattress provides the right balance of comfort and support suitable for side and back sleepers. Stomach sleepers will do well by choosing the medium firm side.
- This is made with CertiPUR-US certified foam so safety from toxic materials is guaranteed.
- The 30 Night Sleep Trial and 10-year limited warranty are welcome bonuses.
Things to Consider:
- A few customers say that there’s less edge support than expected.
OMR Advantage Score: 9.5/10
The Amerisleep AS4 is designed to have a medium-soft level of firmness, making it appealing to those who want strong support as well as snugness.
The AS4 is made up of three layers. Core support is provided by the 7-inch foundation of high-density poly foam. This is topped by a 2-inch plush transitional foam layer that is configured to enhance airflow and cooling.
Finally, at 3 inches thick, a single layer of Amerisleep’s own plant-based Bio-Pur® memory foam provides exceptional cooling and body contouring. Being highly responsive, this comfort layer also helps to relieve pressure points and encourages an ease of movement that’s not always possible with a memory foam mattress.
As with all of Amerisleep’s mattresses, FDA-recognized Celliant® fiber is used, along with Spandex and polyester, in the bed’s soft covering. Constructed from a combination of highly thermo-reactive minerals, Celliant has a number of health benefits, including improvements in circulation and body temperature regulation.
Because the AS4 is a medium-soft mattress, it’s attractive to a wide range of sleepers—from side-snoozers to combination sleepers who change positions throughout the night. Couples will also like this bed, as the blend of foams absorb movement easily, making motion transfer virtually non-existent.
Strengths We Love:
- The three-layer design makes it a mattress with a high profile that many people prefer. You will find it easier to get in and out of bed since little physical effort is necessary, a boon if you have knee issues.
- The combination of three layers of foam ensures that the optimum balance between comfort and support is achieved. There’s no need to add a mattress topper and other accessories except for the usual linens.
- Most customers report that their usual health issues including lower back pain, stiff neck and sore shoulders were gone after a few nights of use. This is the ultimate proof of a mattress’ effectiveness!
- The mattress can last for more than 6 years but it comes with a 20-year warranty. It’s also available with free shipping.
Things to Consider:
- It may be too expensive but it’s well worth the price.
OMR Advantage Score: 9/10
Too hot to sleep? It can be a serious problem. Research has shown that the likelihood of sleep decreases when body temperature rises. So if you regularly find yourself wide awake and hot as blazes in the middle of the night, you might need to consider changing your mattress.
The Signature mattress by Brooklyn Bedding is a luxury mattress that’s widely considered to be one of the best cooling mattresses available online. It has a high-end hybrid design featuring no less than five different layers. And this includes the first layer of TitaniumGel infusion technology, as well as a cool-to-the-touch cover made of a blend of polyester, rayon, and phase-change material.
The cover is not removable, so you can’t machine wash it, but spot cleaning will suffice in getting rid of spills and stains.
The Signature isn’t particularly inexpensive, but alongside it’s great cooling capabilities, you also get more bounce for your buck thanks to its coils and foam combo.
Underneath its hyper-elastic TitanFlex™ polyfoam and memory foam comfort layers is a robust, pocketed coil support core and a high-density polyfoam base layer.
The edge-to-edge coil system provides strong edge support, while the memory foam layers work well to absorb movement, ensuring motion transfer is significantly reduced.
The mattress is available in three firmness options: Soft, Medium, and Firm. Be aware, however, that the Medium is more medium-soft, so if you’re looking for something a little more solid maybe err on the side of Firm.
Strengths We Love:
- The five-layer design isn’t just for show! The mattress really works in decreasing the severity of back pains, stiff neck and sore shoulders. There’s maximum support for your pressure points and comfort for your entire body, thanks to the ingenious multilayered design.
- There’s plenty of choices in terms of level of firmness. You can then buy a mattress with a specific firmness level for every member of your household.
- The 10-year warranty is an attractive feature, but the mattress itself has a usable lifespan of about eight years. It comes with a 120-night sleep trial, too.
Things to Consider:
- Slightly more expensive price.

The 10-inch, mixed-foam Lull mattress is a good fit for those wanting a moderately firm mattress with a slight memory foam feel.
It’s made up of three CertiPUR-US® Certified foam layers and offers close conforming, without the feeling of being sucked into the mattress.
This is mainly due to the strong foundational layer of high-density poly foam, which measures a sturdy 7 inches. On top of this is a transitional layer of blended latex and poly foam that works to support the body while maintaining proper spinal alignment and weight distribution.
The top layer of gel-infused memory foam is designed with cool sleeping in mind. But it’s also aimed at creating comfort by relieving pressure points for sleepers.
The memory foam also helps absorb and limit motion transfer, and as the bed produces little or no noise when bearing weight, it’s a good choice for couples.
Wrapping the mattress is a soft, easy-to-remove polyester cover.
In terms of cost, the Lull mattress is one of the more competitively priced memory foam mattresses, and it is also shipped for free to anywhere in the continental U.S. (except Alaska and Hawaii).
When it launched in 2016, the Cocoon Mattress by Sealy saw its popularity soar almost immediately, thanks in part to media maven Oprah Winfrey flagging it as one of her favorite products of the year. And with fans like that, there’s no way the Cocoon couldn’t be listed in our list of the 10 best online mattresses.
Celebrity endorsement aside, this is a great mattress for those who want a cool but cozy sleep experience with ample spinal support. First, the cover is engineered with a proprietary phase-change material that alleviates and absorbs body heat—making this bed a good bet for those who sweat while they sleep.
Second, the mattress is available in two firmness options. The Soft option has three layers: a high-quality memory foam, a transition layer, and a base of dense polyurethane foam. This gives it a quintessential memory foam feel that will be loved by those who like to feel “hugged” by their mattress.
The Firmer choice has two layers, comprised of the comfort memory foam layer and supportive polyfoam, and is best for those who prefer to feel they’re sleeping “on” rather than “in” their mattress.
The overall dense memory foam construction makes this mattress particularly attractive to back and stomach sleepers, though in truth, it’s comfortable for all people regardless of their preferred sleep style.
Add to that the fact that it’s virtually silent when bearing weight, and you can expect to enjoy many nights of undisturbed shut-eye.
The Swedish-founded Tempur-Pedic, now part of the Sealy International stable, is one of the best-known mattress brands on the market. Though they provide a wide range of high-quality foam mattresses, their most popular is the Tempur ProAdapt, a model included in the brand’s newest Adapt series.
This high-performing memory foam model comes in three firmness options (Soft, Medium, and Firm), and it’s also available as a hybrid mattress with a ‘Medium’ firmness.
The available options make a difference depending on your sleep style. For example, the pressure-relieving, high-density polyfoam base layer in the all-foam Soft and Medium options offer optimum comfort for side sleepers, while the Firm’s solid foam core is particularly suited to back and stomach sleepers as well as heavier folk. The Medium Hybrid is good for all types of sleepers, and it also offers a bit more bounce and support since it has a coil foundation.
Like all of Tempur-Pedic’s mattresses, the ProAdapt is highly durable and has a longer than average expected lifespan of at least 7 years. This is good news, as the bed doesn’t come cheap!
The all-foam versions are also virtually silent and isolate a significant amount of motion transfer.
A further big buying attraction of the ProAdapt is the dual-layer, cool-to-touch cover, which helps dissipate heat. This seriously soft cover also zips on and off, which means it’s simple to wash and likely to last.
Mattresses don’t get much cheaper than the Zinus Green Tea Memory Foam mattress. With a very reasonable price tag, it’s easy to see why it’s one of the most popular mattresses to buy on Amazon. But is it any good?
Available in 6-, 8-, 10-, and 12-inch designs, the mattress is made entirely of foam. A top layer of memory foam is followed by 2 inches of pressure-relieving high-density polyfoam (except in the 6-inch model), and a further strong polyfoam base. Regardless of the thickness you choose, the mattress has a true slow-melt memory foam feel to it and so is perfect for those who like a little hugging while they’re napping. That said, heavy-set folk should probably steer clear as pleasant spooning can quickly change to that traditional memory foam “quicksand feeling.”
It’s likely not a good pick for back or stomach snoozers, either. However, side sleepers will find the gentle body contouring great for pressure relief around hips and shoulders. Its all-foam construction also means motion transfer is kept to a minimum.
The cozy-feeling jacquard knit cover gives the mattress a stylish look. And though it is removable, the company claims doing so will affect the warranty.
Another plus with this bed is that it contains odor-neutralizing particles of charcoal as well as using natural green tea within its memory foam, both of which work to keep the mattress fresh. This also makes the mattress eco-friendly and its CertiPUR-US® Certification proves the point. That said, some owners have reported problems with off-gassing (i.e. that “new mattress” smell you sometimes get when unboxing a bed) with the Zinus Green Tea Memory Foam Mattress.
Though they’ve been around for less than five years, Casper is one of the best-known online mattress brands. They have a selection of several quality mattresses, but their Original Casper Mattress still tops the list as their most popular.
Measuring 12 inches thick, the brand’s flagship model is a CertiPUR-US® all-foam bed, though a recent hybrid version of this star player was recently launched.
Sticking with the original construction, however, there are four layers consisting of memory foam and high-density polyfoam. Also, the bed boasts a transition layer of Zoned Support, specifically targeting pressure points and pain relief.
Starting at the top, the comfort layer is made of a special open-cell foam that acts a little like latex in terms of bounce and breathability. This makes the bed a great choice for combination sleepers, as it significantly absorbs and minimizes motion.
A layer of memory foam comes next, offering comfortable conforming, while the following Zoned Support doubles down on comfort by providing firmness and softness where needed. A high-density polyfoam layer provides the bed’s base, and at 7 inches thick creates the mattress’s solid foundation.
The Casper’s cover is made of a soft polyester blend and has a zipper, which makes it easier to remove.
The GhostBed is a full-foam, competitively priced mattress from bedding product company Nature’s Sleep.
Its CertiPUR-US® comfort foam layers are composed of breathable aerated latex above heat-transferring gel memory foam. The latex gives the bed a soft, springy feel, and together with the cooling memory foam ensures you’ll do more comfortable sleeping than sweating.
The combo of this comfort layer also creates a more balanced foam feel rather than the sink’n’sleep of traditional memory foam mattresses. So if you like that slightly stuck memory foam feeling, this is not the mattress for you.
The foundation of the mattress (7.5 inches of high-density polyfoam) forms and ensures good spinal alignment without making the bed too solid feeling. That said, on a scale of 1 to 10, the GhostBed does rank at around a 6.5, which for light and petite people can make for a firm feel.
The smooth mattress cover is made with a blend of viscose and polyester. This makes it pretty stretchy, meaning it’s less likely to wrinkle or bunch up over time.
And while a further plus-point for this mattress is that it offers a bit better edge support than other full-foam beds, it is still susceptible to sinkage around the bed perimeter over time.
The Leesa is a multi-layer all-foam mattress and the flagship product from the top online mattress company of the same name.
It has a double comfort layer. The first layer consists of 2 inches of pillow-soft, but long-lasting LSA200™ cool foam, which provides superior pressure relief and support. Beneath that is a second layer of equally pressure-reducing memory foam.
At 6 inches thick, the support layer of dense polyfoam provides the base and bulk of the mattress, pushing the overall height to a standard 10 inches.
The mattress is covered with a soft, removable cover made from a blend of polyester, viscose, and lycra. It has a slightly ribbed texture, but that only adds to its cozy quality.
In terms of overall feel, the Leesa is rated as a Medium mattress, making it pleasantly firm for light-limbed folk and slightly softer for heavier people.
As the memory foam is not on top, you feel comfortably cushioned rather than completely cocooned as you sleep. That said, the Leesa mattress does conform very closely to help keep the spine aligned and alleviate pain and pressure points throughout the body.
The all-foam construction also results in above-average motion isolation, and noise while moving around the bed is practically non-existent.
The thick comfort layer and good body balance that this mattress provides makes it popular with petite back and stomach sleepers, though side and combo sleepers can benefit from the ample pressure relief, particularly around the hips and shoulders.
Additionally, if you tend to sleep hot, the Foam Technology microcell structure allows for increased airflow, keeping sweaty bedhead at bay.
As a company, Leesa donates one mattress for every 10 sold and works with One Earth to ensure a tree is planted each time a single mattress sells. That means, not only can you sleep comfortably if you buy a Leesa bed, you can sleep with a clean conscience too!
With the many options today, choosing the right mattress may not be easy. However, we have given you a few options to consider to hopefully narrow it down. And, most companies who sell their products online also offer a “try-out” period… so you can be sure you like it. Get yours ordered today!
