Memory foam mattresses may suit a wide range of people due to their pressure-relieving and supportive qualities.

There is limited scientific research into who memory foam suits best, but a 2022 study indicates that a memory foam mattress may help support the abdomen and pelvis in people who are pregnant and reduce pelvic girdle pain. The participants of the study also received coaching from a physiotherapist.

However, memory foam has a reputation for retaining heat, and may not be the best option for people who sleep hot or those who live in warmer climates.

Those with larger bodies may also not find memory foam supportive enough.

People may wish to consider the following when choosing a memory foam mattress:

  • Certifications: People may wish to look for mattresses that have certifications from organizations such as CertiPUR-US and GREENGUARD Gold. These certifications mean that the mattresses are free from materials or compounds that are hazardous to human health.
  • Cooling features: Memory foam is denser than other mattress materials and may sleep hotter. People may wish to choose a product that has cooling features such as cooling gel to avoid overheating during sleep.
  • Firmness: Firmness is subjective, and people should always choose the firmness that feels most comfortable. That said, most people will find a medium-firm mattress suitable to sleep on.
  • Height: Mattresses with more height tend to have extra layers, which may provide more comfort. However, people who may find it difficult to sit on a bed or to get out of bed may prefer to choose a thinner mattress.
  • Size: People should always purchase a mattress that is the same size as their bedframe.
  • Motion isolation: People can check if the mattress minimizes motion transfer. This may be suitable for couples, as they are less likely to wake up if the other partner changes position or gets out of bed.
  • Sleep position: Check what sleeping positions the mattress is compatible with. People may read customer reviews to learn about others’ experiences.
  • Pressure relief: Some mattresses come with pressure-relieving mattresses. This means that they distribute the individual’s weight and reduce the amount of pressure they apply on a specific area.
  • Off-gassing: Some mattresses emit a strong odor when a person unpacks them. This occurs due to VOCs as manufacturers may use flame retardants during production.
  • Edge support: Individuals may check if the mattress offers edge support. This may help prevent sagging and help the mattress retain its shape.
  • Warranties and sleep trials: People may wish to purchase from companies that offer more generous sleep trials and warranty lengths.
  • Price: Memory foam mattresses can be expensive. People should consider the features they need and their budget, using sleep trials to test mattresses.

Take our quiz to find the best mattress.

Although memory foam is not a new mattress material, not many studies have investigated its impact on sleep quality or back pain.

One 2018 study compared memory foam mattresses with other types of mattresses and found that participants using the memory foam mattress reported better sleep and less body pressure.

However, an older 2014 analysis of previous research found no statistically significant differences between a memory foam mattress, a firm foam mattress without springs, and a waterbed for people with chronic back pain.

A person’s health needs change over time, and what works for one person may not work for another. When choosing a mattress, it is a good idea to consider factors such as body weight, any injuries or joint conditions, age, and climate to find the best option.

Common types of memory foam include:

  • Traditional memory foam: This contours to a person’s body shape and position and offers pressure-relieving effects. It comes from petroleum-based products and has an open-cell structure. Mattresses using traditional memory foam may trap heat, so they may not suit hot sleepers.
  • Gel-infused memory foam: These mattresses contain gel beads, a swirling liquid gel, or a gel that covers the comfort layer. This helps keep the body cool during sleep and provides pressure-relieving benefits.
  • Plant-based memory foam: This type of memory foam may appeal to people looking for a more environmentally conscious memory foam option. It contains plant-based ingredients such as soy.
  • Copper-infused memory foam: Some manufacturers infuse their memory foam with copper. As a heat conductor, it can draw heat away from the body to keep people cool while they sleep. Copper may also have some antimicrobial and antibacterial properties.

There are many other types of mattresses on the market. Some other popular mattress types include:

  • innerspring mattresses, which contain steel coils surrounded by layers of cotton or stuffing
  • pillow-top mattresses, which have a soft, pillowy layer on top
  • hybrid mattresses, which blend newer technologies such as memory foam and gel with a traditional spring core
  • airbeds, which feature pockets filled with air
  • waterbeds, which are filled with water and create the sensation of floating

Each type has its pros and cons, so it is worth looking into what each can offer.

Organic and natural mattresses can also be better for the environment, which is another consideration for many consumers.

Here we answer some common questions about memory foam mattresses.

When should I replace my memory foam mattress?

People should replace their mattress when they notice it does not give them enough support. This may mean people wake up with aches and pains or notice sagging or soft spots on the mattress.

Can memory foam mattresses go on slats?

Yes, people can place memory foam mattresses on slats.

However, the slats should be close together. Slats that are not close together may lead to the memory foam mattress sagging into the spaces.

Are memory foam mattresses too hot?

Memory foam mattresses can be denser than other types of mattresses as they do not contain springs that allow extra airflow through the mattress. Therefore, memory foam mattresses may sleep hotter.

However, people can choose mattresses that contain cooling technology such as cooling gel, which may prevent overheating.

Which memory foam mattress brand is best?

Popular brands selling memory foam mattresses include Nectar, Casper, and Saatva, among many others.

While Nectar provides very affordable memory foam mattresses, some brands, such as Saatva, may use more natural materials.

Each memory foam mattress will have individual advantages and drawbacks, and the best memory foam mattress brand will depend on what a person is looking for. People should prioritize brands that use CertiPUR-US certified foam, provide lengthy warranty and sleep trials, and offer affordable products.

Is a memory foam mattress better than a spring one?

Memory foam mattresses may provide more even support than spring mattresses because of their more uniform construction. They can also conform more accurately to a person’s body shape and position than a spring mattress.

However, people should test memory foam mattresses before they commit to buying them, as they can vary in quality, comfort, and support.

What are the disadvantages of memory foam?

One of the most well-documented disadvantages of memory foam is that it retains heat. It can also be heavy.

Due to memory foam’s ability to quickly conform to a person’s body, some people feel “stuck” in memory foam mattresses. They can also lose form and develop dips over time.

There is also a risk of off-gassing with memory foam mattresses. To limit the risk of off-gassing, many companies use CertiPUR-US certified foam.

What makes a mattress the best memory foam mattress depends on a person’s sleep preferences, how much support they like to have, whether or not they tend to overheat, and other considerations.

To find the right fit, a person can take note of their personal needs and make use of risk-free trials that many mattress companies offer. This can help them test out the mattress to see if it helps them sleep well.
