Quick Overview

Memory foam, also known as viscoelastic polyfoam, is a material that softens when it comes into contact with body heat and then retains its original shape once it cools. Memory foam mattresses are typically constructed with at least one layer of memory foam in the comfort system; the support core is almost always made of high-density polyfoam.

Best Memory Foam Mattresses

Memory foam mattresses conform closer than other mattress types. This results in better spinal alignment and more pressure relief throughout the body. Memory foam also isolates motion transfer and produces little to no noise when bearing weight. These two qualities make memory foam beds suitable for couples, particularly if one or both of the sleepers awaken easily due to motion or noise.

Read on to review our choices for the top memory foam mattresses sold today. Each pick is based on verified customer and owner experiences, as well as intensive product analysis.

Best Luxury Overview

For years, Winkbeds mattresses have exemplified luxury and exceptional quality in the innerspring and hybrid types and this MemoryLux is no exception. Given that history and the quality of this new memory foam offering, we’ve chosen the MemoryLux as the ‘Best Luxury’ pick for memory foam mattresses sold today. The MemoryLux is a 12″ bed available in multiple firmness options and is an all-foam bed with a memory foam comfort layer and a high-density foam support core; available in ‘Medium Soft’ (4), ‘Medium’ (5), and ‘Firm’ (7) settings. This selection ensures most sleepers will find a mattress that aligns with their firmness and conforming preferences.

Temperature neutrality is another key strength. Between the breathable cover components and the use of more breathable engineered foams in its comfort layers, the MemoryLux doesn’t trap quite as much body heat as a traditional memory foam mattress. Other benefits include great motion isolation and no noise when bearing weight.

Though it comes with a slightly higher price tag, the MemoryLux is not as expensive as similarly constructed mattresses which can retail for more than double. Winkbeds offers White Glove delivery for a small fee – including in-home assembly and old mattress removal – and also stands by the MemoryLux with a 120-night sleep trial and lifetime warranty.

Good for:
  • Every type of sleeper (side, back, stomach, combination)
  • Sleepers in all weight groups (light, average, heavy)
  • Sleepers who prefer a higher profile mattress
  • Couples

Best for Lightweight Sleepers Overview

Sleepers in the light weight group (under 130 pounds) tend to prefer mattresses that balance a high degree of body-cushioning comfort and a bit of stable support. If the bed is too soft they will likely experience too much sagging, while overly firm surfaces tend to create more aches and pains.

Our memory foam mattress pick for sleepers in this weight group is the Leesa, which offers a ‘Medium’ feel that conforms and alleviates pressure without sinking excessively.

The Leesa is also a good option for couples. Three foam comfort layers – including a middle memory foam layer – isolate motion transfer very well, and the bed does not make any noise when bearing weight. The mattress is suitable for all sleep positions, as well. Side sleepers enjoy cushioning beneath their shoulders and hips, which can improve spinal alignment, while most back and stomach sleepers find the bed provides great support.

The Leesa’s price-point is fairly low compared to other memory foam beds. Leesa also offers free shipping to all 50 states, and backs the mattress with a 100-night sleep trial and a 10-year warranty.

Good for:
  • Sleepers in any position (side, back, stomach, combination)
  • Sleepers who weigh 130 pounds or less
  • Couples
  • Those with neck, shoulder, and back pain

Best for Average Weight Sleepers – Loom and Leaf

Best for Heavyweight Sleepers Overview

Sleepers with a higher body weight are often cautioned against memory foam mattresses because they can sink too deeply into the mattress and in a way that can threaten spinal alignment. The Plank Mattress from Brooklyn Bedding is an exception to the rule as it provides plenty of firmness while still cushioning pressure points.

In fact, the firmness of the Plank is a two-sided affair. On one side, it has a Firm feel that is around a 7 on the 1-10 firmness scale. On the other side, it has an Extra Firm feel around an 8.5 to 9. Adjusting the feel of the mattress only requires turning the mattress over, and this gives heavyweight sleepers more liberty to find the right fit for them.

The construction of the mattress includes a quilted top on either side. On the firm side, there is 1.5” of quilted material that includes 1” of gel-infused memory foam. This ensures that even though this side is firm, it can provide padding where the body needs it most. Underneath this foam layer is 7” of high-density polyfoam that acts as the support core. On the other side of this polyfoam is 2” of TitanFlex foam, a gel-infused polyfoam that has moderate contouring and bounce. The quilted cover on the extra firm side is .75” thick and covers the TitanFlex layer.

The Plank tends to stay cool thanks to gel-infused foams, and for hot sleepers, there is an option to add a cooling panel made with a phase change material (PCM) that helps to further dissipate heat.

Brooklyn Bedding has over two decades in the mattress industry and offers free standard shipping, a 120-night sleep trial, and a 10-year warranty for the Plank mattress.

Good for:
  • Anyone looking for a firm mattress
  • Those who tend to sleep hot
  • Sleepers who want the option of varying their firmness setting

Memory Foam Mattress Buyer's Guide

Initially developed by NASA researchers in the 1970s, memory foam is today one of the most popular comfort layer materials on the market. Memory foam is also commonly known as ‘viscoelastic polyurethane foam’ or ‘low-resilience polyurethane foam (LRPu)’. However, it’s important to note that not all memory foam mattresses are strictly polyurethane-based (see next section for more details). In addition to mattresses, memory foam is also commonly found in pillows and mattress toppers.

Memory foam bridges the gap for mattress comfort layers. It combines the low cost and shape retention of traditional polyfoam with the superior support and body-contouring of a latex comfort layer. An important characteristic of memory foam is that it is viscoelastic, meaning that it changes shape when pressure is applied, and then returns to its original form once the pressure is released. Memory foam is also designed to respond to temperature. When you are lying on memory foam, your body heat will cause the foam to become softer, which allows the material to conform to your figure. After you get up, the memory foam will cool down and return to its original, firmer shape.

Memory foam mattresses are ideal for certain types of sleepers. Side sleepers, for instance, benefit from an exceptionally soft comfort layer because it allows their hips and shoulders to sink into the mattress properly. Side sleeping on a mattress that is too firm can lead to aches and pains caused by spinal misalignment. Memory foam can also help sleepers with chronic back or shoulder pain. The material is designed to conform to your figure and alleviate pressure points, leading to a comfortable, relatively painless night’s sleep. Additionally, memory foam is engineered for low motion transfer — and may be ideal for light sleepers who easily awaken when their partner moves or shifts positions. For those requiring a firmer feel, hybrid memory foam mattresses are constructed with a memory foam comfort layer and an innerspring support core.

Types of Memory Foam Mattresses

You’ll find several varieties of memory foam mattress available on the market. Some of the most popular models include:

  • Traditional (or viscoelastic) memory foam is the most widely available variety of the material. It is polyurethane-based, and categorized as a type of polyfoam.
  • Plant-based memory foam is manufactured using a combination of petrochemicals and botanical ingredients. Plant-based foam layers are designed in an open-cell configuration, making them more breathable and cooler for sleeping than standard memory foams.
  • Gel-infused memory foam is a relatively new material, and is not as widely available as other memory foam types. The addition of cooling gel helps reduce heat and keep you sleeping comfortably. The shape retention of gel-infused memory foam is comparable to traditional memory foam.
  • Copper-infused memory foam, another relatively new version of the material, features beads lined with thin copper wire placed throughout the foam. Like gel, the copper components will help you sleep cooler throughout the night. This material is also designed to help sleepers with joint pain and stiffness, since copper is known to aid with blood circulation.

The Feel of Memory Foam

The popularity of memory foam is largely due to its ‘customized’ feel. Let’s explore some key qualities of memory foam mattresses:

  • Conforming: Memory foam will conform closely to a sleeper’s body. This creates a contoured impression in the sleep surface that provides even body support and helps maintain spinal alignment. As a result, memory foam sleepers often experience high levels of pain and pressure relief.
  • Sinking: Memory foam tends to be softer than other mattress materials. This may be ideal for people who are average weight or lighter than average, but those who weigh more than 230 pounds may experience excessive sinking. This can undermine support and lead to added aches and pains.
  • Motion isolation: As memory foam conforms to a sleeper’s body, it absorbs motion transfer whenever he or she shifts positions in bed. This helps minimize disruptions in other areas of the mattress, and can be beneficial for couples who share a bed — particularly if they are restless sleepers.
  • No noise: Most memory foam mattresses are virtually silent when bearing weight.

Density and ILD

Two important considerations regarding memory foam mattresses are density and indentation load-deflection (ILD).

Density is measured in pounds per cubic foot, and is used to indicate how well the mattress will support your body weight. Most memory foam comfort layers range in density from 2.5 pounds per cubic foot to 8 pounds per cubic foot. A common industry benchmark for a high-quality memory foam mattress is a density of 4-5 pounds per cubic foot. Density is used to categorize memory foam into three grades: low, medium and high. The table below features a detailed breakdown of memory foam density.

Grade Density (pounds per cubic foot) Characteristics
Low 2.5 to 3.9 lbs/ft3 Retains original shape very quickly; offers good motion isolation and some contouring
Medium 4.0 to 5.9 lbs/ft3 Retains original shape somewhat slowly; offers very good motion isolation and good contouring
High 5.5 lbs/ft3 and higher Retains shape very slowly; offers excellent motion isolation and contouring

While density measures the supportiveness of memory foam, ILD is used to gauge the firmness of a mattress. ILD indicates how much pressure is required to make a four-inch indentation on the top surface of a mattress. The higher the ILD number, the firmer the mattress. Some mattresses carry an ILD range, rather than a single number, because the firmness may be influenced by other factors, such as room temperature. Most memory foam mattresses on the market have a comfort layer with an ILD number that falls between 8 and 20; as a general rule, look for memory foam mattresses with an ILD of at least 10. The table below explores ILD numbers in-depth.

ILD Rating Category Characteristics
8-10 Extremely Soft Most sleepers experience significant sinking
11-15 Very Soft Most sleepers find this to be the ideal softness/firmness level for a memory foam mattress
16-21 Soft Minimal sinking, and less contouring than mattresses with lower ILD ratings

Memory foam is also available in a wide range of ILD ratings. Exceptionally soft memory foam will conform to your body more easily, but may also create a ‘sinking’ feeling that some sleepers find uncomfortable. On the other hand, ultra-firm memory foam provides a more stable sleep surface but is not as effective at alleviating pressure points.

Because the material is so soft, a ‘memory foam mattress’ is not entirely made of memory foam. Rather, the comfort layer (usually 25% to 40% of the mattress) is made of memory foam, while the larger support core is constructed from a sturdier material — usually high-density polyfoam — to prevent you from completely sinking into the mattress.

Other Important Considerations

In addition to the density, ILD number and mattress construction, there are several other factors to consider when shopping for the right memory foam mattress.

  • Cooling elements: Due to the contouring effects of memory foam, many people find that these mattresses sleep warm to the point of discomfort. Cooling components (like the gel and copper-infused foams mentioned above) are designed to reduce this effect — although the extent to which they reduce heat retention has been debated.
  • Comfort layer thickness: Memory foam mattresses will vary based on the thickness of the top memory foam layer. A thicker top layer may provide added support for certain sleepers, such as heavier people who feel they need extra cushioning and support.
  • Mattress cover: The top cover — located above the comfort layer — will also vary in its thickness, as well as the material used to make it. Covers that are thicker or constructed from less breathable materials may cause you to sleep hot, and also may affect the responsiveness of the memory layer.
  • Mattress composition: Many foams are made from flame retardants and other chemicals. While these materials are generally regarded as safe, they are not necessarily eco-friendly. Plant-based foams or foams certified by organizations like CertiPUR-US are considered somewhat better for the environment.

Pros and Cons of Memory Foam

  • The material conforms closely to align the sleeper’s spine and evenly distributes their weight
  • Memory foam sleepers report above-average pain and pressure relief
  • Foam isolates and absorbs motion transfer to help couples reduce nighttime disruptions
  • Memory foam mattresses produce little to no noise
  • The mattresses are usually compressed for shipping, allowing customers to order them online without a truck


  • Memory foam tends to retain a fair amount of body heat from sleepers, causing the mattress to sleep excessively warm for some
  • Some sleepers — particularly heavier individuals — report uncomfortable sinking and inadequate mattress support
  • Memory foam mattresses are not very bouncy, and some couples say they are not responsive enough for sex
  • Off-gassing potential is high for memory foam beds, and some mattresses emit odors for weeks after they are removed from their packaging.

Memory Foam Lifespan and Mattress Warranties

The lifespan of a memory foam mattress will depend largely on the foam’s density grade. Low-density memory foam will retain its shape quickly, but the material degrades at a faster rate and has the lowest amount of motion isolation. High-density memory foam, on the other hand, offers superior body-conforming and low motion transfer — although this material is slower to retain its shape after each sleep. Medium-density memory foam provides a compromise between low- and high-density foam in terms of cost, shape retention, motion isolation and other key factors.

Most memory foam mattresses are designed to last for at least five years of regular use. In order to maximize the lifespan of your memory foam mattress, you’ll need to look carefully at the material composition of the mattress — in particular, the ratio of memory foam to cheaper types of polyfoam in the comfort layer and the support core. Also take time to inspect other aspects of the mattress, such as the type of stitching found on the cover and seams.

Additionally, you should make sure your memory foam mattress comes with a robust warranty. Although the warranty length is key, you should also understand what the warranty covers. For example, the best memory foam mattress warranties should cover sagging, one of the most common issues associated with memory foam. The warranty should also discuss in clear terms how the manufacturer handles warranty claims, turnaround time, shipping costs and mattress replacement. For more information about warranties, please visit our guide to Understanding Mattress Warranties.

Cost of a Memory Foam Mattress

Memory foam mattresses will vary considerable when it comes to price point. Some models cost as little as $300 to $400, while high-end and luxury memory foam mattresses will cost upwards of $3,000. Foam density is one factor that affects price; low-density foam will be the cheapest, while high-density foam is usually the most expensive. Plant-based memory foam, as well as gel- and copper-infused foam, will typically cost more than standard viscoelastic memory foam mattresses.

According to our findings, the average Queen-size memory foam mattress costs $1,044.

Important Questions for Consumers

When purchasing a memory foam mattress online or in a store, make sure to inquire about the following characteristics.

  • What is the material composition of the foam?
  • How thick is the comfort layer?
  • What are the density and firmness (ILD rating) of the foam?
  • How long should I expect this mattress to perform before a replacement is needed?
  • Will this mattress provide adequate support and comfort, given my preferred sleep position?
  • For couples: will this mattress be comfortable for both of us?
  • Is the bed constructed from materials that will produce off-gassing smells?
  • Is there a trial period for testing out the mattress? If yes, then what is the return policy?
