Within the past two decades, memory foam mattresses have skyrocketed in popularity and now account for roughly 20% of beds sold. Memory foam’s quick rise in demand is due largely in part to the excellent pressure relief, body contouring, and deep compression support it offers. Memory foam mattresses also work well for the bed in a box industry because they can be easily rolled, compressed, and shipped straight to the customer’s door. Despite its many benefits, memory foam has some downsides, such as its ability to trap heat.
Luckily, companies have begun to innovate cooling foam to solve this problem, and new technologies appear every day to give customers the best night of sleep possible. In this article, we’ll share our top recommendations for foam mattresses in 2020, all the pros and cons of memory foam, and how other factors can affect the type of bed you purchase (such as budget, weight, health concerns, and more).
The Amerisleep AS3 contains pressure-relieving, plant-based memory foam and clinically proven support technologies to properly support side sleepers. Plus, it comes with a lengthy 20-year warranty, giving you the most for your money.
The Zoma Sports Mattress features state-of-the-art Triangulex™ technology that uses hundreds of triangle shapes cut into the memory foam for excellent pressure relief and support.

What’s more, all of the Amerisleep mattresses are CertiPUR-US® certified.
Amerisleep Warranty and Sleep Trial
Amerisleep’s 20-year warranty is prorated. In the first 10 years, Amerisleep will replace your mattress free of charge if there are any material or workmanship defects in the mattress. They offer the best warranty we’ve seen so far, covering indents ¾ inch deeper or more (most companies cover sags 1 inch or more). During the last 10 years of the warranty, Amerisleep will replace or repair your mattress, but you must pay a percentage of the cost (this percentage depends on how long you’ve had the mattress).
100-Night Sleep Trial
Amerisleep offers a 100-night trial period where you can sleep on their mattress to ensure it will suit your needs. If you decide you don’t like the mattress, you’re more than welcome to send the mattress back. Amerisleep doesn’t restock their mattresses; therefore, there isn’t a restocking fee. Instead, Amerisleep donates the used mattress to a charity near you.
If the mattress was not what you expected, but you still want to try another option, you can exchange your mattress for another one of their 5 models. Once you have selected your new mattress and your old mattress has been picked up, your new mattress will be delivered to you and you will be refunded or charged with the difference between the two mattresses.
Next on our list is the Zoma Sports Mattress, a memory foam mattress for athletes. Zoma is designed to help athletes sleep deeper, recover faster, and perform better. Though it’s targeted to athletes, the Zoma can upgrade anybody’s sleep and help them feel more refreshed in the mornings.
The top layer is gel-infused memory foam with Triangulex™ technology. When you lay down on the Zoma, this layer molds to your body and offers instant comfort and pressure relief. The gel within the foam combats body heat and keeps you at a comfortable temperature while you sleep.
Triangulex™ technology offers dynamic back support to foster a healthy spine. Near your midsection, this foam feels firmer to offer extra lumbar support and prevent uncomfortable sinkage. Around your shoulder and hips, Triangulex™ contains triangle-shaped cutouts allowing for deeper compression under those major joints. This technology keeps your spine in line with the rest of your body and prevents back, neck, and hip pain.
The second layer of Zoma is Reactiv™, a latex-like poly-foam. Designed to be more responsive than memory foam, Reactiv™ gives this bed a bit of bounce and prevents you from ever feeling “stuck” in the mattress. Its responsiveness makes it easier to change sleeping positions or climb in and out of bed.
The third and final layer of Zoma is Support+, a durable poly-foam. Support+ reinforces the layers and sleeper above and prevents sagging throughout the mattress.
Zoma Mattress Warranty and Sleep Trial
Zoma will repair or replace your mattress if it develops a sag or indentation greater than ¾ inch.
100-Night Sleep Trial
Zoma offers a 100-night sleep trial with each of their beds. If you decide against it, they’ll arrange for it to be picked up and locally donated or recycled.
3. Bear Mattress
This graphite gel-infused memory foam mattress has three distinct layers for increased durability and support. Bear made this mattress specifically for athletes or anyone with a fairly active lifestyle. The medium firmness level is an excellent choice for anyone who doesn’t want to sacrifice comfort for pressure relief.
A breathable Celliant® cover wraps around the three layers of foam. Celliant® is an FDA-determined textile which promotes a more restful sleep, improves performance, and keeps you nice and cool.
Thanks to its responsive transition foam layer and high-density support foam layer, motion transfer is practically non-existent.
Bear Mattress Warranty and Sleep Trial
This warranty covers any visible indentations deeper than 1 inch as long as the mattress was used with a compatible foundation. If the mattress shows any deformities within the first 10 years of ownership, Bear will cover the cost of repairs or replacements. The outer cover of the mattress is only covered under the warranty for the first year.
100-Night Sleep Trial
Bear asks that you try out the mattress for at least 30 nights before you initiate a return. If you find the mattress unsatisfactory after the 30 days (but before 100), Bear will arrange for someone to pick up the mattress and you will be refunded.
4. PlushBeds Cool Bliss® Luxury Memory Foam Mattress
The PlushBeds Cool Bliss® memory foam mattress stands at 12 inches tall and is made with gel-infused memory foam. This foam improves airflow throughout the mattress and dissipates heat and moisture 3 times faster than other brands’ infused gel foams. The luxurious stretch cover has advanced cooling properties to keep you from sleeping hot.
Underneath the gel comfort layer lies a 100% natural latex support layer. Latex cradles the body and relieves aches and pains while properly supporting the spine and back. It’s also a naturally eco-friendly material. This mattress is GreenGuard Gold certified, so you shouldn’t experience any chemical odors or off-gassing when you unbox the mattress.
The 5 inch supportive core is made of high-density polyurethane foam, and customers even have the option of purchasing PlushBeds’ very own orthopedic base to use with their mattress.
PlushBeds Warranty and Sleep Trial
PlushBeds offers a 25-year warranty which covers indents or sags deeper than 1.5 inches and other defects in the material’s construction. During the first 10 years, PlushBeds will cover repairs or replacement costs, and in the last 15 years, some of that cost is up to the customer.
100-Night Sleep Trial
You can try out the PlushBeds mattress for 100 nights risk-free. They ask that you try out the bed for at least 30 nights, allowing time for your body to adjust to the new mattress. If, after those 30 days, you’re still unsatisfied, contact them to initiate a return. You will need to box up the mattress, but PlushBeds will pick it up.
5. Nest Bedding Alexander Signature Series® Flippable
Nest Bedding makes a variety of mattresses and other sleep accessories, but their Signature Series® flippable mattress is one of our favorites. One side of the mattress is medium, while the other is luxury firm. An organic cotton cover covers the surface of the mattress, and underneath that is two inches of gel memory foam, two inches of transitional foam, and seven inches of a luxury base foam.
We recommend the medium side for most sleepers since it has the right balance of give and support. If you prefer a firmer surface, you can try out the other side.
All of Nest Bedding’s foams are CertiPUR-US® certified and made in the USA.
Nest Bedding Warranty and Sleep Trial
Nest Bedding offers a lifetime warranty with their mattresses. This warranty protects against certain defects as long as you own the mattress. Sags greater than 1 inch are covered, as well as any manufacturing flaws in the zipper or cover. You must use the mattress on a compatible foundation (see their website for more details).
100-Night Sleep Trial
Your sleep trial begins when your mattress is delivered, and Nest Bedding asks that you try the bed for at least 30 nights before initiating any return, since this time period allows for you to adjust to the mattress. If after the 30 days you still aren’t satisfied, contact Nest about returns or exchanges.
6. The Muse Mattress
The Muse Mattress uses unique cooling technologies to keep anyone who uses it completely temperature-neutral all night long. First, their Diamond Breeze cover is made using phase-changing material which absorbs the ambient temperature in the room instead of your body heat. Then, the first layer of gel memory foam dissipates any lingering heat and keeps it away from you.
The 8-inch base layer made of high-density foam aids in edge support, so you won’t feel like you’re sinking in or rolling off the mattress during the night. If you’re unsure which Muse Mattress firmness is right for you, they have a Sleep Quiz on their site that matches you with the ideal mattress— you can choose from a soft, medium, or firm mattress.
Muse Warranty and Sleep Trial
The Muse Mattress comes with a 10-year warranty, beginning at the original date of purchase. The warranty covers any manufacturing defects, as long as the owner takes care of the mattress using instructions on the care tag. The owner must also use the bed on a proper foundation. The Muse warranty covers sags greater than ¾ inch.
120-Night Sleep Trial
If you’re unsatisfied with your mattress anytime during the 120-night sleep trial, you can return it for a refund. Muse will arrange to have it picked up and will donate it to a local charity.
Types of Memory Foam to Consider
Memory foam is not the only foam in an “all-foam mattress.” Like we mentioned earlier, even the most basic all-foam mattress has a high-density foam in the base and then softer foam in the top. The top layer is sometimes made of memory foam, but other brands use latex foam, polyfoam, or gel-infused foam. They all feel a little different and serve different purposes to accommodate a wide variety of users.
Traditional Memory Foam (Viscoelastic Foam)
This is the type of foam most of us associate with mattress foam. Memory foam is a blend of polyurethane foam and additional chemicals that make it viscoelastic. Memory foam’s viscoelasticity gives it that structured and firm feel upon initial contact before you sink into the body of the mattress. Additionally, traditional memory foam mattresses will provide you with a more pronounced contour, as they are traditionally less responsive than other foams.
Polyurethane foam, also known as polyfoam, is often found in memory foam mattresses, but the two materials are not quite the same (although they are often conflated). Polyurethane foam is synthetic and often blended with other compounds. Polyurethane foam often leaves an off-gassing odor and is lower-quality than some viscoelastic memory foam— this is why many brands have begun to manufacture all of their foams using eco-friendly processes.
Gel Memory Foam
Gel-infused memory foam is one of the most popular types of memory foam you will find on the market. That’s because the gel infusion cools down the foam, hence helping the user avoid that all too familiar problem: sleeping hot. It also makes foam even more springy and conforming.
Gel foam was actually invented by Charles Yost, the same person that invented memory foam for NASA in the 1970s. Most brands use gel a couple of different ways in their foams.
One of the most popular ways mattress brands use gel is via gel beads, which are usually made with ceramic and conduct heat away from the body. However, some companies prefer gel infusion since it disperses heat all throughout the mattress instead of in concentrated areas where the beads are.
Infusing foam with gel involves introducing the gel as a liquid at the beginning of the manufacturing process, which also causes it to disperse evenly across the foam. When someone sleeps on a gel-infused mattress, the gel absorbs their body heat, and it then redistributes it throughout the foam.
While gel foam mattresses do work to cool down the body at least temporarily, there are other factors to consider that will keep you cool for longer: open-cell foam, lighter-density foams, and even your bedding.
Examining the pros and cons is a great first step in the research process, but there’s more to a mattress than meets the eye— some of the most important components of your mattress can’t be seen, but it helps to know how they all come together to make the bed comfortable (or not).
Foam Density and ILD
Lower density foam is softer, more responsive, and more pliable. That’s why you’ll most likely find it in the top layers of a foam mattress. On the other hand, high-density foam is much harder and sturdier, so brands use it as the support core of a mattress. Firmer mattresses use fewer low-density foam layers than softer mattresses do. When you’re thinking about which mattress to buy, consider that firmer mattresses generally last longer because they are constructed with more high-density foam.
If you’re opting for a soft mattress, make sure there is a thick layer of high-density foam in the base or wrapped coils for stability. A thick or thin mattress doesn’t correlate with density— it’s all about the different layers and their composition. That said, if you are heavier or share your bed with a partner, you will want a thick mattress that’s also on the firmer side so it holds up to compression and wear over time.
A high-density foam mattress carries two important implications: if a mattress has a higher density it is more likely to have a longer lifespan, but it is also going to generally retain more heat. Therefore, these dense foam mattresses will likely result in a warmer night’s sleep. What is considered a reasonable middle ground between the longevity of the bed and its heat retention lies in medium-feel mattresses, made with a balanced combo of high and low-density foams.
Your body weight also has an effect on how dense you will like your mattress to feel. Heavier individuals who weigh over 250 pounds will probably like a firmer mattress and one that is at least 12 inches thick, as it will need to withstand more pressure over time. A lighter person, on the other hand, would probably prefer a softer mattress since they won’t sink in too much and will still need some support and cushioning to keep their posture neutral.
You can get really technical with foam density by looking at the ILD. The ILD, or Indentation Load Deflection number, measures how much weight a mattress can withstand before being indented 1 inch deep. A mattress with a high ILD is firmer, while one with a lower ILD is softer. A mattress rating with an ILD of 14, for example, is considered very plush, while one with an ILD of 40-44 is very firm.
Since most companies don’t widely advertise the mattress ILD on their website, you can look for an easier-to-read firmness scale, which goes from 1-10, one being very soft and 10 being very firm. Most mattress fall between 3-8 on this scale.
The thinner the mattress cover, the more breathable your mattress is likely to be. Now, many companies use cooling technologies in their cover fabrics to increase breathability or they use naturally breathable fabrics such as Tencel or bamboo.
The best memory foam mattresses generally have a minimum of four inches of comfort memory foams. Each layer of a mattress tends to have a specific thickness for a reason, and they all come together to create the desired comfort and support combination. If a mattress has less than four inches of comfort foam, it will typically feel firmer.
Most mattresses are between 10 and 14 inches thick— anything thinner than 10 inches won’t be supportive enough for most adults. All foam mattresses have a high-density foam base layer, but the thickness of that layer increases the firmer the mattress.
Your sleeping position has a huge impact on your night’s rest. For example, a side sleeper will most likely feel uncomfortable on a firm mattress, but stomach sleepers prefer this type because it keeps their hips and back neutral and straight. Each sleeping style will feel comfortable on a slightly different mattress type and firmness.
Side sleepers are most comfortable on a medium-soft or medium mattress because these offer a nice balance of support and softness. Side sleepers won’t want a too-soft mattress as this will cause their hips to sink down, causing pain and exacerbating other existing medical issues such as bad posture or chronic pain.
Side sleeping is one of the healthiest sleeping positions for your posture, but if you sleep on your side with your arms under your pillow, you may run the risk of paresthesia, or “pins and needles.” To combat this, choose a medium-soft or medium mattress and a medium pillow that keeps your head from pressing down too heavily on your arms.
Back sleepers need a medium-firm or firm mattresses because they usually want to feel like they are on top of the mattress, not sinking down into it. Back sleepers are at less risk for back pain compared to other positions, but they are more likely to snore or develop sleep apnea. A medium-firm mattress and pillow should keep the head elevated enough to prevent the tongue from collapsing into the throat, which causes snoring.
We don’t recommend sleeping on the stomach because it puts the user at a higher risk of misaligning their spine, hips, pelvis, and back, causing pain and other health problems. However, if you’re in the habit of sleeping this way, choose a medium-firm or firm mattress.
Stomach sleepers may also be fairly uncomfortable on foam mattresses because they sink— if you want to sleep on foam and you like sleeping on your stomach, choose a foam mattress with a high-density foam base.
Warranties and Lifespan
A standard mattress warranty is 10 years long and it covers manufacturing defects or damage beyond normal use. Most warranties cover sagging or indentations up to a certain depth (an average of 1 inch). Some companies offer longer warranties, but they are usually prorated, meaning the customer pays a portion of the cost for repairs and replacements after the first ten years or so.
A good-quality foam mattress usually lasts 7-10 years, and so a warranty longer than that may not be completely necessary. However, you should invest in a mattress with a good warranty because it will give you some peace of mind and it tells you how long a company is willing to stand behind their product.
Lifetime warranties are becoming more popular, but they are not much better than a typical 10 or 20-year warranty since mattresses don’t last a full lifetime.
Other Mattress Types
If after reading the article above, you’ve decided maybe memory foam isn’t for you, don’t worry. There are other mattress technologies to consider, from latex to innerspring to a combination of materials.
Latex is made from the sap of a rubber tree, and its environmentally-friendly manufacturing process makes it a great green mattress option. Latex isn’t heat-activated like foam, and therefore retains less heat. It’s also aerated, made with holes in the surface, to promote better airflow. Latex is soft like memory foam, but it is much bouncier and feels more firm than memory foam. If you’re looking for close-conforming material, memory foam might be a better option than latex. However, if you like the soft support of memory foam but need the bounce, latex is a good choice.
Latex is also extremely durable— latex mattresses can last up to 15 years, making them one of the longest-lasting mattress types.
A hybrid mattress combines the benefits of innerspring and foam in a 50/50 combo— usually, the top layers are made using memory, latex, or polyfoam, and the bottom layer is always composed of innerspring coils. Newer hybrid models (made within the last 5-10 years) often use wrapped coils in the base for better motion isolation.
Using coils in the base increases the airflow and adds bounce— two things memory foam isn’t known for. Then, the top layers are made of foam for close-conforming, pain-relieving cushioning— things innerspring mattresses don’t typically offer. Hybrid mattresses can be more expensive than other types because they use a lot of materials. It depends on the brand and the construction, so look at these things carefully before you purchase one.
Despite memory foam’s surge in popularity, innerspring beds still make up a large portion of mattress sales. You may know these mattresses as pocketed coil mattresses, innerspring mattresses, or simply as spring mattresses. These beds will provide the coolest sleep, but they also provide the least amount of conformity to your body and sometimes end up creating pressure points. Innersprings have a layer of foam or another soft material in the top layer, sometimes called the “pillow top.”
These mattresses also have the lowest customer ratings because they tend to sag quickly. Newer models have begun using wrapped coils, which make the bed quieter and boost the motion isolation abilities of the bed. Lots of innerspring beds have layers of high-density foam between the soft layers and the coils to act as a buffer against any potential sagging or indents. If you’d like a bed with good bounce, even support across the surface, and good airflow, an innerspring is probably a great choice for you.
Does memory foam sleep hot?
Because of their composition, you will find that hybrids and innerspring mattresses are generally cooler than memory foam. However, don’t let this deter you from considering a memory foam mattress. Since the invention of high-quality covers, gel-infused memory foam, and open-cell structures, memory foam mattresses have greatly improved their ability to release heat and allow for breathable airflow without compromising the support that is so crucial to a memory foam mattress.
Look for foam mattresses made using gel-foam— be wary of gel beads, since these are often not as effective as gel-infused foams. Some brands even infuse their foams with graphite, copper, or charcoal, which all conduct heat away from the body and are naturally antimicrobial.
Most memory foam found in the top comfort layers of a mattress is open-cell, meaning it should increase airflow through the mattress better than higher-density, closed-cell foams (often found in the base). If the foam mattress you’re looking at doesn’t use open-cell foam, it may sleep hot.
Is memory foam slow to respond?
You can test the responsiveness of your mattress by pushing down on it and then releasing to see how quickly the foam adapts or springs back. While different foams vary in responsiveness, the innate viscoelastic qualities of a memory foam mattress mean that it will be relatively slow to respond while conforming closely to the shape of whatever sits on top of it.
Viscoelastic means the foam takes on viscous and elastic characteristics when weight and/or heat is applied to it.
The slow responsiveness of memory foam is the very thing that allows for the contouring that provides firm and consistent support. However, if you are more accustomed to a bed with bounce, you may want to avoid memory foam mattresses. If you’re worried about sinking too far into your foam mattress, choose a medium-firm or firm foam bed, as these are made with thicker layers of high-density foam in the base.
What does memory foam feel like?
Most foam mattresses have a relatively similar composition and structure. The base layer of most foam mattresses is a thick, high-density polyfoam, creating a solid foundation for the other layers.
The order, type, and number of foams layered atop the polyfoam base varies across brands, but the simplest foam mattress has just one thick polyfoam base layer and then a thinner, softer memory foam comfort layer.
Viscoelastic memory foam is easy to identify because of its unique composition and feel. It’s also easily compressed with the pressure and weight you apply to it.
Does Memory Foam Have Good Edge Support?
You’ve probably heard about edge support. But what does it mean? Is it important for helping you get a good night’s sleep?
Some mattress companies make their beds firmer on the edge, this is called edge support. There are pros and cons to this, but generally companies are moving away from this practice.
While edge support makes it easier to sit on your bed, it also reduces the amount of sleeping surface you have. Surprisingly, sleeping on the edge of the bed is fairly common, so if the bed felt firmer there, that means you are no sleeping on what you paid for.
With the rise of bed-in-box technology, memory foam mattresses, edge support isn’t as common as it used to be.
So, when shopping for a new memory foam mattress, don’t be surprised when all the best options don’t utilize edge support.
Is a memory foam mattress right for you?
Memory foam is a great technology and makes for a comfortable, pressure-relieving mattress. However, that doesn’t mean it’s for everyone.
Memory foam mattresses are ideal for:
- People who are experiencing back or shoulder pain, thanks to its pressure-relieving abilities.
- Side and back sleepers, as the memory foam contours nicely to the shape of the body in these positions.
Memory foam mattresses may not be right for:
- Heavier sleeps: Those who need the mattress to support over 300lbs on each side should consider a speciality mattress
- Organic shoppers: If having a 100% organic mattress is important to you, you will need to look at
How much should I budget for a new foam mattress?
The cost of a memory foam mattress varies greatly because it depends on a wide variety of things: the quality of the foam, its density, whether or not it has any certifications, the length of the warranty, sleep trials, return policies, white glove delivery options, and even the brand name. The average queen-size memory foam mattress costs about $1,000, although some cheaper models cost as little as $300 and luxury models can be up to $3,000.
When you’re budgeting for a new mattress, keep in mind your top priorities. If you want your mattress to last a while, invest in one with higher-density foams and a good warranty (at least 10 years). If you have allergies or skin sensitivities, opt for foam mattresses with plenty of green certifications. If you aren’t worried about sleeping hot and you just need a soft place to sleep, don’t worry about spending extra on a mattress with gel or graphite-infused foams.
Is a foam mattress good for everyone?
We believe sleep is an individual experience, and as such, there is no “one-size-fits-all” mattress. Read mattress reviews written by customers to get an idea of how each mattress fits different preferences. Some websites let you filter reviews by concern, so you can read how someone with back pain enjoyed (or didn’t enjoy) their mattress.
Foam mattresses are popular because they can be shipped in a box directly to the customer’s door and they work well for most sleeping positions, those with back pain, and anyone seeking pain relief. They’re also relatively affordable. While memory foam beds now are made with various firmness options to accommodate most sleepers, you should try out as many types as you can (latex, innerspring, and hybrids) to find the one that best fits your needs and lifestyle.
What is a “sleep trial” and how does it work?
Lots of mattress companies have begun to offer sleep trials with the purchase of a mattress. This is especially common with foam bed-in-a-box mattresses, since they ship directly to the customer, foregoing the “try it out in a showroom” experience for a more personalized, in-home one.
Most sleep trials last around 90 nights, giving the customer plenty of time to adjust to their new bed. If a company doesn’t offer a sleep trial, they should offer some sort of customer satisfaction guarantee in its place. We suggest buying a mattress with a generous sleep trial and easy return policy, allowing the customer to get a refund for the bed within the sleep trial period.
To write a quality and credible article, we considered over 20 leading mattress brands, read several dozen reviews and articles, and spent over 20 hours researching, writing, and editing.
Foam mattresses are rising in popularity thanks to their soft, conforming feel and their ability to relieve pressure for pain sufferers. Many brands sell foam mattresses at various price points, making them affordable for most, and they include sleep trials so you can get a good idea of how the bed will fit your lifestyle. If you’re still unsure which foam mattress to buy after reading our guide, don’t worry— choosing a bed is a big investment— one you shouldn’t take lightly.
