In making this article, we immersed ourselves in the ins and outs of memory foam including how it’s made, the sleep-promoting benefits it brings to the table, and its potential downfalls. We also compared over 30 different beds looking for brands who stand out amongst the crowd for delivering truly better sleep. Finally, we spent 23 hours writing and revising the article to deliver the most relevant information about memory foam and memory foam mattresses.

1. Amerisleep AS3

amerisleep as3 best mattress for side sleepersAmerisleep’s AS3 mattress is the best memory foam mattress because it is engineered to deliver an even balance of comfort and support, and is versatile enough to adapt to a variety of sleepers.

The top layer of the AS3 is Amerisleep’s Bio-Pur® foam. This plant-based memory foam is five times more breathable and than traditional memory foam, allowing for air to easily pass through this layer.

When you lay on this layer, the memory foam will hug your body’s curves and offer instant comfort. However, this layer is also designed to be responsive, ensuring you don’t feel trapped in the bed.

Amerisleep uses HIVE® technology in its next layer to offer unbeatable zoned support. To make this technology, they cut hexagons in strategic comfort zones. In areas where you need more support, these hexagons are placed closer together and feel firmer to prevent you from sinking unhealthily far into the mattress.

The last layer of this mattress is Amerisleep’s Bio-Core® foam. The base of the mattress is durable foam designed to help prolong the lifespan of the mattress by preventing premature deterioration and sagging. Amerisleep also backs their beds with an impressive 20-year warranty.

Because the Amerisleep AS3 mattress is designed to be adaptable, it’s great for a variety of sleepers including back sleepers, side sleepers, and those who tend to snooze in a variety of positions throughout the night.

A queen AS3 comes in at $1,499 in price, but Amerisleep regularly runs mattress promotions, so if you watch their site, you could probably snag a deal. Plus, Amerisleep offers a 100-night trial with each of their beds.

Amerisleep AS3 Highlights

  • Features plant-based memory foam, making it great for eco-friendly shoppers
  • Adapts to most body types to be comfortable for the majority of sleepers
  • HIVE® technology promotes healthy sleep positions

2. Zoma Mattress

zoma sports mattressNext up on our list is the Zoma Mattress, a memory foam mattress for athletes. The goal behind the Zoma was to create a mattress that can help athletes get deeper, better sleep in order to recover faster and play harder. If you live an active lifestyle, the Zoma is for you.

Alternatively, Zoma is an ideal choice for those combating recurring pain points. With an emphasis on recovery, this bed can offer relief for old pains and prevent new ones from forming.

The first layer of the Zoma is 2 inches of cooling gel memory foam. When you lay on this bed, the memory foam molds to your body to offer instant cushioning comfort. The gel within this layer combats body heat to keep you sleeping comfortably.

Zoma’s Triangulex™ technology is located within the top layer of their bed to offer your back dynamic support. Around your shoulders and legs, this technology contains triangle-shaped cutouts to allow for deeper compression and pressure relief— this is especially important for side sleepers who need extra cushion near those major joints. Then, this technology firms up the midsection of the top layer, allowing for extra lumbar support and preventing uncomfortable sinkage.

Next, is a layer of highly-responsive Reactiv™ foam— a latex-like poly-foam. The responsiveness of this layer gives the bed a bit of bounce and creates a more “on top of the bed” feel in regards to firmness. Primarily, Reactiv™ functions as a transition foam between the cushioning memory foam above and the durable core of the mattress below.

Last but not least is the core of the mattress, durable Support+ foam. The Support+ foam reinforces the two layers above and prevents premature deterioration and sagging.

The Zoma Mattress comes with a 100-night sleep trial and a 10-year warranty.

Zoma Mattress Highlights

  • Designed to be comfortable for the majority of sleepers
  • Features sleep-enhancing Triangulex™ technology
  • Gel memory foam combats body heat to keep you comfortable all night long

3. Amerisleep AS4

as4 best soft mattressWhile we recommend Amerisleep’s AS3 as the best memory foam mattress, we also like their AS4 and AS5 and recommend those to sleepers looking for a softer mattress. While the AS3 is versatile, some reviews of it mention it not feeling as soft as expected, so if you’re looking for a notably soft bed, go with one of these models.

The Amerisleep AS4 contains 4 inches of pressure-relieving memory foam, giving you a whole extra inch of memory foam than what’s in the AS3. This extra inch of foam allows for deeper cushioning and creates a cloud-like feel. Though it allows for some sinkage, it still contains HIVE® technology to keep your spine neutrally aligned. The AS4 can be a comfortable option for side and back sleepers but is likely too soft to properly support side sleeping.

The AS4 has three different layers: 4 inches of Bio-Pur®, 1 inch of Affinity with HIVE®, and 7 inches of Bio-Core®. Like all Amerisleep mattresses, the AS4 comes with a 100-night sleep trial and a 20-year warranty.

Amerisleep AS4 Highlights

  • Features 4 inches of pressure-relieving memory foam
  • Comfortable for side and back sleepers
  • Equipped with a cooling cover to regulate your body temperature

4. Amerisleep AS5

The softest mattress Amerisleep offers is their AS5. Despite being so soft, their AS5 is actually a great mattress for heavy sleepers. While sleepers over 250 pounds often struggle to find a soft but supportive mattress, the AS5 is designed to be just that.

The AS5 contains an extra layer none of the other Amerisleep mattresses have– Active Flex. Active Flex is a latex-like poly-foam, and the inclusion of the Active Flex layer prevents plus-size sleepers from sinking uncomfortably far into the mattress.

All in all, the AS5 has four layers: 3 inches of Bio-Pur®, 2 inches of Active Flex, 2 inches of Affinity with HIVE®, and 7 inches of Bio-Core®. The AS5 features a lightweight, removable cover and comes with a 100-night sleep trial and a 20-year warranty just like the other Amerisleep mattresses.

You can find these beds on the Amerisleep website or at one of their select showrooms across the nation.

Amerisleep AS5 Highlights

  • Contains Active Flex technology to boost this bed’s responsiveness
  • Best for side and back sleeping
  • A supportive, soft mattress for heavy sleepers

5. Vaya Mattress

vaya mattress

Are you shopping for a new foam mattress on a tight budget? You don’t have to compromise and settle for a less-than-stellar mattress. The makers of the Vaya Mattress created a bed that’s affordable yet offers pure comfort and support.

A Vaya Mattress has two layers wrapped in a soft and breathable cover. The bed’s basic construction still provides the mix of responsive support and pressure-relieving cushion that sleepers need for a good night’s rest.

The top layer is 3 inches of Vaya Comfort Foam, an airy and adaptable material that molds to you for pressure relief. Underneath the Vaya Comfort Foam is 9 inches of Vaya Base Foam, a sturdy material that promotes mattress longevity.

Every Vaya Mattress includes a 100-night sleep trial, and if you’re not satisfied you can return it for a full refund.

Vaya Mattress Highlights

  • Budget-friendly two-layer design
  • Light and breathable comfort foam relieves pressure
  • Excellent for all sleepers

6. Bear Mattress

bear mattressBear designs their mattresses with athletes in mind and uses state-of-the-art sleep technology, including Celliant® fabric, to promote a better night’s sleep. They market their mattresses towards those who are active because they’re engineered to foster healthy sleep and alleviate aches and pains. We also recommend this mattress to those who frequently experience aches and pains in the mornings or those who struggle to get a good night’s sleep due to uncomfortable tossing and turning.

Let’s talk about the layers of this bed:

The cover of the Bear mattress is Celliant® fabric. We discussed the perks of using this material when we covered the Amerisleep AS3, however as a reminder, this material promotes better sleep by regulating your temperature.

The first layer of this mattress is graphite-infused memory foam. A perk to using graphite in this layer is enhanced temperature control. As you can expect, the memory foam in this layer should cradle your body upon laying down on this bed.

Bear uses two layers of poly-foam as the “middle” layer of this mattress. They design this poly-foam to be more responsive than memory foam, so it should suspend your body in the mattress and prevent you from sinking too far.

The base layer of this mattress is a high-density poly-foam base. They design this base to be long-lasting, but back their beds with a 10-year warranty just in case anything were to happen.

The Bear mattress comes with a 100-night risk-free sleep trial, and costs $840 for a Queen.

Bear Highlights

  • Celliant® fabric offers multiple sleep-promoting benefits
  • Best for side and back sleepers
  • Good option for sleepers seeking pain relief

Pros and Cons of Memory Foam

Memory foam mattresses have been steadily growing in popularity since the 1990s for many reasons. Let’s talk about all of the great sleep-promoting benefits it brings to the table.

Memory foam has the ability to contour to your body unlike any other material, due to its viscoelastic properties. Because it has this functionality, it can cradle your body while you sleep, releasing stress and tension.

These beds can help reduce chronic aches and muscle pains, specifically lower back pain. As memory foam molds to your body, it evenly distributes your body weight throughout the bed, resulting in even support from head to toe.

These beds also help foster your spines alignment by properly supporting your body’s curves.

Memory foam is exceptional at isolating motion. Share the bed with someone who tosses and turns all night long? A memory foam bed could be the solution for sound sleep. Because these beds are designed to cradle your body in a healthy position, they should also prevent you, or a restless partner, from tossing and turning in discomfort throughout the night.

Memory foam mattresses are almost virtually silent, too, considering they’re lacking noisier materials such as springs.

In general, memory foam mattresses receive excellent customer reviews. Review sites like Sleep Like the Dead compile customer feedback, and rank memory foam at an 81% satisfaction rating.

Now, it’s important to note, memory foam is not the end-all-be-all of mattress materials, and these beds do come with their downfalls. Let’s talk about their cons.

These beds are prone to off-gassing. In the production of memory foam, petroleum is used to give the material it’s foam consistency. Without petroleum, there is no memory foam. Unfortunately, the use of petroleum can lead to unpleasant odors when first unpacking your new mattress, often referred to as a “new mattress smell.”

The best mattresses are trying to combat this issue by using more eco-friendly materials in their mattresses such as plant-based foam. Other companies engineer poly-foam to be similar to memory foam, so they can offer the same benefits to their customers without the negatives of memory foam.

Memory foam can trap heat. Some foams are not breathable enough to allow for air to flow in and out of the mattress easily, meaning any body heat you emit during the night can get trapped in the material below you.

Mattress brands are integrating cooling gels and engineering their foams to be more breathable to prevent you from sleeping hot on their beds. If you’re somebody who’s prone to sleeping hot, memory foam may not be the best material for you.

The risks above are much more prominent in cheap materials, such as a foam mattress topper. Look for companies which are CertiPUR-US® certified to help you find your top pick.

And, as always, consider your sleeping position (do you sleep on your side or back or stomach?) to help you find which type of mattress is right for you.

What Makes the Best Memory Foam Mattress?

Just because a mattress is memory foam doesn’t always mean it’ll be high-quality.

In order to find a top-notch memory foam mattress, there are a few things to look consider, including types of memory foam, their densities, thickness, firmness, and more. Below, we’ll discuss how to judge a quality memory foam mattress.

Types of Memory Foam

Not all memory foam is created equal. There are typeof memory foam that is more open-cell in construction, promoting healthy airflow. Some types of foam have a greater chance of heat retention.

Below, we will go over the more general types of foam in our quest to explain what constitutes a high-quality memory foam mattress.

There are essentially three varieties you will come across in the present marketplace: traditional, gel, and plant-based.

All of these types represent the visco-elastic characteristics to varying degrees and mainly differ in ingredients and manufacturing methods.

Traditional memory foam is made from polyurethane with solely petroleum-based components. This is the original manufacturing method for visco-elastic, temperature-sensitive foams, seen in other brands.

While traditional brands provide the notable benefits like pain relief and motion isolation, odorous off-gassing and trapped heat can be an issue for a portion of people.

Plant-based memory foam replaces a portion of ingredients with plant-based materials. These sustainable mattresses reduce chemical concerns and have also been shown to improve comfort when it comes to sleeping temperature.

Plant-based foams, like those from Amerisleep, can be made with a larger cell structure and with more stable temperature sensitivity which may reduce complaints seen in traditional foams, but there can be concerns of misrepresentation as with latex-based foams being presented as memory foam.

Gel memory foam is made using traditional poly foams layered or infused with gel (blended in or beads/particles). This mattress type is popularized by brands like Serta and is the most recent, claiming to sleep cooler than traditional.

While gel foam may create a cool sensation initially in some models, there are concerns of gels affecting durability over time and not living up to coolness claims (according to sources like Consumer Reports).

Memory Foam Density

One of the key features used to compare memory foam mattress brands is density, which is measured by the weight in pounds of a 12″ by 12″ square of material, or pounds per cubic foot. Foams are made more or less dense by changing the ratio of polymers to air.

Low density memory foams can be more responsive, cheaper, and less likely to trap heat, but break down quicker and may not offer enough support. High-density foams last longer and excel at support, but tend to trap heat, hinder movement, and cost more.

More so, you want a mixture of high density and low density foam in your mattress to help with motion transfer. A mattress with bad motion transfer will lead you to wake up throughout the night as your sleeping partner moves.

  • Low Density — 3.5 lbs and less
  • Medium Density — 3.5-5.0 lbs
  • High Density — 5.0 lbs and more

In addition to the density of the memory foam layer, the core or support foam density also plays a role in longevity and support, with 1.8 lbs and less considered low, 2.0-2.5 lbs considered medium, and over 2.5 lbs considered high.

The vast majority of brands use cores between 1.5 and 2.5 lbs.

Mattress Firmness

Indentation Load Deflection refers to force required to compress a material 25% or one inch on a four inch sample, depending on the test. Lower numbers reflect softer materials while higher numbers reflect firmer. With this type of mattress, firmness options depend on several factors: the ILD of each foam comfort layer and core, and the thickness of all layers.

Since ILD numbers are so important to knowing the firmness level of a mattress, it’s a shame more companies aren’t upfront about the ILD of each layer. If you can’t find this information on the company website, consider reaching out and asking a customer support representative.

The range for memory foams is typically 10-16 ILD, where core foams register ILDs between 20-45. Mattresses with thicker layers of memory foam will also typically feel plusher than those with less.

Not all manufacturers will disclose this information, but if they do it can help you make a more objective decision rather than relying on more arbitrary terms like soft and extra-firm.

Room temperature also plays a role with foams that are more sensitive to temperatures, as cooler rooms will make the foam feel firmer while warmer rooms and body heat will make the foam feel softer. Temperature-neutral foams will have less fluctuation and the firmness should feel more stable.

Mattress firmness preference is fairly subjective topic, but sleep studies have shown the majority of people will prefer medium to medium-firm beds for overall comfort and pain relief.

The best starting point is to consider your current mattress firmness and whether you want something similar or different.

Mattress Thickness

Different compositions of different layers can actually make a large impact on individual comfort.

When comparing different models, looking at the layers within the mattress proves important, both for understanding the relative value the mattress offers, the potential lifespan and how comfortable it will be for you.

Some brands also use filler foams and other materials in the upper layers, which is important to know since these may be less durable and reduce comfort over time.

For example, consider two beds that are the same price and size. One has 4″ of 4.0 lb memory foam over a 7″ core. The other has 2″ of 3.0 lb memory foam, 1″ of regular foam and an 8″ core.

Even though they are the same overall thickness, the first mattress contains an additional 2 inches in the comfort layer and a higher density.

The second bed would represent less value at the same affordable price, since it contains less memory foam and lower density.

Foam Responsiveness & Viscosity

The responsiveness refers to how quickly it contours or returns to its original shape after being pressed. Traditional memory foams have a slow-response rate since they rely on body heat to conform and soften.

Newer generations can be made with less temperature sensitivity, which creates a more responsive material that contours and returns to its original shape more quickly.

In terms of comfort, slow response foams provide a sinking or melting sensation and close contouring that some people enjoy but others may describe as being trapped in a hole or sinking in quicksand.

Those with mobility concerns may also prefer more responsive foams since changing positions and getting out of bed requires less effort compared to slow-response foams.

Heat Traps and Bad Odors

Though memory foam rates among the highest of all mattress types in owner satisfaction, two complaints that come up most often include warmer sleeping and an initial odor.

For a majority of people, these are not an issue but about 10% of people report sleeping hot and about 15% report a strong odor.

The factor most associated with sleeping hot is high foam density. Dense memory foams tend to contour more closely and are also less efficient at circulating air.

Mattresses with thicker layers of dense foams tend to receive more complaints of heat than lower density beds and those with thinner layers.

While almost all newly manufactured products have some type of odor, the primary concern some have with poly foams is volatile organic compounds.

VOCs encompass around 60 gasses that various compounds (often petroleum-related) release over time as they break down.

Though many of the worst offenders have been banned for use, mattress companies are not required to disclose ingredients so it can be hard to tell what is or is not in a mattress.

Certi-Pur is an independent organization that tests polyurethane foams and only certifies those that have been found to have low-VOC levels, and do not contain chemicals of concern like PBDEs and formaldehyde.

If odors and chemicals are a concern for you, consider checking for this certification when shopping and see what reviewers say.

Tired of waking up sweaty? Find the best memory foam mattress for sleeping cool

Mattress Covers

The cover on a memory foam mattress should complement the characteristics of the materials within. Breathable fabrics like cotton and rayon may be more preferable than polyester-blend knits for those who sleep warm.

The material should also be able to stretch with the memory foam as it contours to your body and rebound without getting saggy.

Covers should contain no more than 1″ of padding, quilting or fiber between your body and the memory foam layer(s), since any more could reduce the contouring and pressure reducing benefits.

Sleep Positions & Body Type

Different body shapes deform foam at differing degrees in different places, which can affect what feels comfortable to you.

Don’t forget to take your personal needs such as sleep position and body type into consideration when shopping as well.

Side sleepers need thicker layers of memory foam to prevent pressure on hips and shoulders, whereas back and stomach sleepers require less since less of your body “sinks in”.

Petite people may also feel comfortable with thinner-profile mattresses, though larger-framed people will feel more comfortable on thicker mattresses.

Therefore, if you are a 150 lb back sleeper, an 8-9″ mattress may be a good option, but a 250 lb side sleeper would do better with a 12-14″ mattress. For couples with significant differences, finding a middle ground or a customizable solution may be necessary.

Mattress Warranties & Sleep Trials

All mattresses should come with a warranty, though length and terms often vary. Most brands will have both a full coverage period (5-15 years) and sometimes a longer pro-rated period (5-15 additional years). Quality mattresses should have full coverage periods that extend through the expected lifespan of the mattress (at least 10 years ideally).

You also want to find out how deep impressions must be before warranty coverage kicks in. Surveys have indicated that sagging over one inch can significantly affect comfort, so a warranty that covers impressions of one inch or less would be ideal.

In-home trial periods are offered by many retailers and allow customers a window in which they can return after buying. This is especially important if you are trying memory foam for the first time. Ask what fees are associated with returns. Some charge only return shipping, while others have restock fees, pickup fees, and other costs.

You should have a minimum of 30 days to return or exchange in order to get a feel for the mattress since it can take time to fully adjust to new beds.

While buying online can seem counter-intuitive, online retailers tend to have more generous return policies (and even showroom shopping doesn’t guarantee satisfaction since 40% of buyers report remorse).

Other Mattress Types

Memory foam mattresses are great for pain relief and sleepers looking for a “cloud-like” bed, but they aren’t always a fit for everyone. Sleepers who are prone to night sweats may find memory foam too warm, and elderly sleepers may find it hard to change sleeping positions and feel “stuck” in these beds. While memory foam mattress brands take these potential sleeping concerns into account when building their beds, it’s a simple fact that other mattress types may just be better for certain sleep needs.

In this section, we compare memory foam mattresses to latex, hybrid, and innerspring beds to help you decide which type of mattress is best for you.

Memory Foam vs. Latex Mattresses

Memory foam and latex mattresses are both considered “all-foam” beds, but memory foam mattresses feature memory foam and latex mattresses feature layers of latex (as you might imagine). It’s hard to say which of these types of mattresses is “better” because it comes down to personal preference.

Latex and memory foam have a distinctly different feel. While memory foam is known for feeling “hug-like” or “cradling,” latex mattresses are described as feeling more “lifting.” These beds hold you more on top of the mattress rather than cradled within. If you prefer firmer mattresses, you may like latex better than memory foam.

Latex mattresses are also a popular choice for eco-friendly shoppers searching for an organic bed. Some memory foam mattresses are eco-friendly because they use plant-based foams and eco-conscious manufacturing methods, but latex beds are the only true organic mattresses.

Memory Foam vs. Hybrid Mattresses

Hybrid mattresses combine both foam layers and innerspring coils to offer both cushioning and bounce. Many hybrids feature memory foam layers with coils, so you receive the benefits of sleeping on a memory foam bed but with all of the bounce of a traditional innerspring mattress. Plus, hybrids allow for better airflow and less heat retention due to the gaps between the coils.

Not all hybrids feature memory foam, though. Latex and poly-foam hybrids are just as prevalent as hybrids with memory foam. Like we mentioned above, hybrids aim to offer the benefits of each mattress type while mitigating the concerns of each, too. So while many sleepers complain that memory foam mattresses sleep too hot, hybrids combat that by allowing for better airflow.

The one drawback to hybrid mattresses are their price tag. These beds combine multiple high-quality materials and with that, cost more. Some hybrids, such as those with poly-foam, are a bit more budget-friendly; however, cheap or inexpensive hybrids are usually poorly-built and not worth the money. If your budget doesn’t allow for a good-quality hybrid, we suggest choosing a different type of mattress rather than opting for a cheap hybrid.

Memory Foam vs. Innerspring Mattresses

Memory foam and innerspring mattresses differ drastically. Memory foam beds feature foam layers while innerspring mattresses contain no foam layers and instead are characterized by their inner coil systems. Most innersprings do feature a pillow or Euro top, though, that allow for some cushioning comfort.

Innerspring mattresses used to be the most popular type of mattress, but have since lost their allure. These beds aren’t very pressure-relieving, and when the coils begin to wear, offer uneven support. These beds break down faster than most other mattress types, too. We also don’t recommend couples invest in one of these beds because they offer notably poor motion isolation, so if your partner tosses and turns, you’ll be feeling every movement.

If you’re looking for a cheap mattress and only need the bare minimum from a bed, an innerspring will suffice; however, we do not suggest these beds to people looking to make a long-term investment towards better sleep.


What is the best memory foam mattress to buy?

There is no “best” memory foam mattress, as every sleeper has different needs. The best mattress for side sleeping likely wouldn’t be comfortable for a stomach sleeper, so it’s important to keep your own needs and preferences in the front of your mind when shopping.

To judge the quality of a memory foam mattress, look at its construction and sleep-promoting technologies. A good memory foam mattress usually contains a layer with zoned support technology. Zoned support layers typically have firmer areas of foam to offer added support and softer areas to allow for deeper compression; these facilitate better spinal alignment, alleviate pressure points, and promote more comfortable sleep.

One of the biggest complaints with memory foam is its tendency to trap heat, so many modern memory foam mattress companies incorporate some method of cooling into their beds. Some of the more popular cooling technologies include cooling gels or temperature regulation technologies to combat heat retention.

If a mattress is lacking in either or both of these technologies, it’s probably not the greatest.

How do I choose a memory foam mattress?

Choose a memory foam mattress based on your own needs and personal preferences. Do you tend to wake up with aches and pains? Keep those in mind when making your decision. Do you prefer a firm or soft mattress? How do you tend to sleep? All of these questions help you gauge your personal sleeping habits to determine which mattress best compliments you.

Which type of foam mattress is the best?

There are three main types of foam beds: latex foam mattresses, memory foam mattresses, and poly-foam mattresses. The term “all-foam” is often used interchangeably to describe these beds, but these three types of mattresses are very different.

Latex and memory foam mattresses are comparable in terms of quality, but their biggest differences lie in how they feel. We wouldn’t say memory foam is better than latex (or vice versa), but that a sleeper who prefers a more “hug-like” feel from their mattress may like memory foam better than latex. Whereas somebody searching for an organic mattress may choose latex over memory foam.

Poly-foam mattresses, on the other hand, usually are not as high-quality as latex or memory foam beds. Poly-foam is cushioning and comfortable, but it doesn’t relieve pressure as well as memory foam. In fact, when pressure is applied to these beds, they often compress much quicker than memory foam would— so it’s not uncommon for these beds to sag and feel uncomfortable after only a short period. We should note though, that poly-foam is one of the most inexpensive mattress materials, so you can usually find these beds for pretty cheap. A poly-foam mattress may be a good option if you’re buying a mattress to use for a short time, but they’re not the best investment if you’re looking for a long-lasting bed.

How long does a memory foam mattress last?

Most high-quality memory foam mattresses last around 10 years. Cheaper memory foam mattresses don’t last as long, but they should still hold up for five to seven years. Plus, most warranties for memory foam mattresses span 10 years, so should your mattress start sagging or showing signs of indentations, you can usually get it repaired or replaced free of charge.

Are memory foam mattresses good for back pain?

Some of the best mattresses for back pain are memory foam due in part to memory foam’s conformability. Memory foam can contour to your body unlike any other mattress material, making it the best at pressure and pain relief. While memory foam cannot cure chronic back problems, such as scoliosis or herniated discs, it can ease the symptoms of these two common conditions and help you get more restful, pain-free sleep.

Can you flip a memory foam mattress?

Unless a mattress is labeled as “flippable” or “dual-sided,” we recommend against flipping mainly because most memory foam mattresses are built with layers that are placed in a particular order.

More often than not, memory foam mattresses have a solid, durable base layer in place to prevent sagging and support the layers above. Should you flip a mattress like so over, you’d be left sleeping on the firm, uncomfortable core. Doing so would not only lead to aches and pains, but also cause the mattress to break down sooner.

Do memory foam mattresses sag?

Memory foam mattresses, like all other mattress types, can sag. Sagging usually occurs at the end of a mattress’s life, so you should get a lot of years from a bed before it begins to sag or shows signs of indentations.

Plus, many mattress warranties cover sagging, so if your bed starts feeling lumpy after only a few years, you may be able to have it repaired or replaced. Every warranty is different, be sure to read the fine print of your mattress’s warranty before making a final purchase.

Is memory foam toxic?

Memory foam mattresses are not toxic. Though they are made with a number of petrochemicals, mattress manufacturers don’t use these chemicals in high enough concentrations for these beds to be considered unsafe. Memory foam mattresses do sometimes let off an unpleasant odor right after unpacking, though— this is called off-gassing. Many people believe memory foam is toxic due to the release of this odor, but it should not be harmful to your health. Some sleepers report headaches, nausea, and asthma when first sleeping on a new memory foam mattress, but these symptoms usually go away after the mattress has aired out enough. If your bed does have a strong off-gassing odor, we suggest letting it sit in a well-ventilated room for a few days before use.

If you’re concerned about the chemicals in your new mattress, check for a CertiPUR-US® certification. CertiPUR-US® ensures mattresses are free from formaldehyde, phthalates, mercury, lead, ozone depleters, and PBDE flame retardants.

Do you need a box spring with a memory foam mattress?

Box springs are not compatible with memory foam mattresses because they can damage the foam and cause premature wear and tear. Instead, the best mattress foundations for memory foam mattresses are solid and flat, or have slats less than 3 inches apart. You can also set these beds directly on the floor, as well, but we suggest putting a mattress protector around the bed before doing so.


We hope this guide has helped you decide if a memory foam bed is right for you. When weighing the pros and cons of these beds, consider your own sleeping habits.

Also, don’t forget to read customer and mattress reviews during your search to get more insight information about the beds you’re thinking of buying.

If you’ve decided memory foam is solution to your sleep struggles, we’re confident one of the beds on this list could be a great mattress for you.

    • Hi Yvonne,

      Good question! We do not recommend stacking memory foam mattresses because it will result in sagging. Memory foam mattresses are best supported on a solid, flat surface or a slatted surface with slats no more than 3 inches apart.
