Buying Guide for Best Full Size Memory Foam Mattress

  • Pressure Relief and Contouring: A full-size memory foam mattress excels at distributing body weight evenly, providing excellent pressure relief by contouring to your body’s shape, which helps alleviate joint and back pain.
  • Motion Isolation: Memory foam mattresses are known for their ability to minimize motion transfer, making them an ideal choice for couples or restless sleepers who want undisturbed sleep throughout the night.
  • Temperature Regulation Features: Look for memory foam mattresses with cooling technologies, such as gel-infused foam or open-cell construction, to help regulate body temperature and prevent overheating during sleep.

Full size mattresses—also called double mattresses—are one of the best mattress options for single adult sleepers. They don’t take up too much space, nor are they too costly, but they still provide lots of room to stretch out throughout the night.

A full size mattress measures 54 inches wide and 75 inches long. It’s comparable to a twin bed in length but is 16 inches wider for ample sleep space.

For single sleepers considering a new mattress, a full size memory foam mattress is always a good choice. Memory foam is well-known for its excellent pressure and pain relief, motion isolation, and lack of noise to foster a good night’s sleep.

Our easy guide takes you through the best full size memory foam mattresses on the market, as well as the ins and outs of memory foam mattresses.

  • Pressure relief
Recommended For
  • Sleepers who want firmness options
  • Side sleepers
  • Hot sleepers

The Layla Mattress offers a unique, dual-sided design that allows sleepers to choose between a soft or firm feel simply by flipping the mattress. This versatility makes it an excellent option for people who are unsure of their preferred firmness level or those whose preferences may change over time. The mattress uses copper-infused memory foam, which not only conforms to the body for pressure relief but also has natural cooling and antimicrobial properties.

After extensive testing, we found the Layla Mattress particularly effective at delivering comfort on both sides, with the soft side offering deep cushioning and the firm side providing enhanced support. Its innovative flippable design truly sets it apart in the memory foam category.

Dual-Firmness Design
We chose the Layla Mattress because of its unique flippable feature, which provides both soft and firm options in one mattress

Cooling Technology Layla’s copper-infused foam stood out for its excellent heat regulation. The copper helps pull heat away from the body, keeping the mattress cool, which is crucial for those who tend to sleep hot, especially on memory foam.

The Layla Mattress is made up of four high-quality foam layers. The soft side starts with 3 inches of copper-infused memory foam for contouring and cooling, followed by 2 inches of convoluted support foam for enhanced airflow.

The center features a 4-inch core support foam for durability and stability. Flipping to the firm side, there’s 1 inch of copper-infused memory foam for a firmer feel. The mattress is encased in a soft, breathable, zippered cover for easy maintenance.

The Layla Mattress provides two distinct sleep experiences, depending on the side you choose. The soft side offers deep pressure relief, making it perfect for side sleepers or those who prefer a plush feel. On the flip side, the firm option delivers more robust support, which is great for back sleepers or anyone who prefers a sturdier sleep surface.

Reviewer Amanda noted, “I love the flexibility of the Layla Mattress. Some nights I prefer the soft side for a cozy feel, but when I need more support, the firm side is just a flip away. It’s like getting two mattresses in one!”

Pros

Dual-sided firmness
The flippable design allows users to choose between soft and firm, making it versatile for different sleep preferences.

Cooling copper-infused foam
Copper-infused memory foam helps with heat dissipation, keeping the mattress cool throughout the night.


Cons

May be too soft
The soft side provides comfort, but back sleepers who prefer a firmer mattress may find it lacks sufficient support.

What is Memory Foam?

Memory foam—also known as viscoelastic polyurethane form—has been around for roughly 50 years now. It is temperature-sensitive and responds quickly under pressure.

Memory foam is a different type of poly-foam since it’s been treated with non-toxic chemicals to increase the foam’s density and viscosity. So, your simple poly-foam isn’t quite the same as memory foam. Memory foam is more durable and comfortable than poly-foam, which is also why it’s more expensive.

Since memory foam is both dense and responsive, it isolates motion very well. Motion isolation is valuable for couples who share beds so you won’t disrupt each other at night. It’s also great for conforming under your body’s curves and relieving pressure or achiness.

Memory foam mattresses are also hypoallergenic, meaning bacteria, dust mites, mold, dander, and pollen are unable to live within it.

Using a hypoallergenic mattress can prevent symptoms including runny nose, itchy skin, sneezing, coughing, and breathing troubles. Since allergies are so disruptive to your sleep, we recommend using a hypoallergenic mattress—such as a memory foam mattress—to improve your sleep.

While memory foam is great, the primary issues with memory foam are that it gets hot and off-gasses. Memory foam was built to conform in response to heat. While this helps relieve pressure, many hot sleepers complain about memory foam’s heat retention. However, lots of mattress companies have created proprietary memory foams to handle this issue.

Similarly, off-gassing is a strong odor—similar to that “new car smell.” While the intense odor may seem nice for a car, sleeping in an off-gassing memory foam mattress can lead to headaches, breathing problems, and nausea.

We suggest airing out your mattress in a room with open windows for several days when you first receive it to reduce the strong odor.

Another option to avoid this issue entirely is by getting a CertiPUR-US® certified mattress. CertiPUR-US® certified foams are free of formaldehyde, heavy metals, flame retardants, and are low in VOCs, meaning your memory foam bed won’t off-gas.

Types of Memory Foam

While memory foam is a type of mattress, there are multiple variations memory foam comes in. Some common types of memory foam include plant-based, gel, and memory foam with cooling infusions.

Plant-Based Memory Foam

Traditional memory foam contains petroleum-based oils, but with plant-based memory foam, the petroleum is replaced with plant oils. Plant-based memory foam is cooler, stronger, and more environmentally friendly compared to traditional memory foam.

Not only that, but plant-based memory foam contains little VOCs (volatile organic compounds), which are unstable and potentially toxic. So, plant-based memory foam is less likely to off-gas.

Gel Memory Foam

Gel memory foam is a type of memory foam with cooling gels inserted into it. This could mean gel was infused into the memory foam, or perhaps that there is a layer of gel or gel beads added atop the memory foam comfort layer.

The benefit to a gel memory foam mattress is that it keeps your bed cool, considering a common problem with memory foam is that it often traps heat.

Memory Foam with Cooling Infusions

Another option for memory foam is memory foam infused with cooling properties, such as copper, graphite, and green tea extracts. These natural minerals regulate the temperature of your mattress, helping you stay cool.

For example, both graphite and copper absorb and dissipate heat, while green tea extracts get rid of odors and promote cool sleep.

Benefits and Drawbacks of Memory Foam

As with any type of mattress, memory foam is great, but it’s not without flaws. While mattress brands are constantly working to make memory foam better, it still falls short at times. Let’s take a look at some of the pros and cons of memory foam beds.

Benefits:

  • Memory foam conforms closely under the body to relieve pressure points and pain
  • Dense foams isolate motion
  • Doesn’t produce noise, unlike innerspring beds
  • Hypoallergenic foam is dust mite and allergen-resistant
  • Certain types of foam release little to no off-gassing

Drawbacks:

  • Traditional memory foam traps heat
  • Certain memory foams off-gas within the first few nights of use
  • Expensive compared to classic innerspring beds
  • Memory foam can cause sleepers to feel “stuck” in bed

Other Common Types of Full Size Mattresses

If memory foam isn’t up your alley, it’s worth knowing what your other options are. If you want a foam bed, consider a latex mattress. For beds totally unlike memory foam, consider innerspring or hybrid mattresses.

Latex Mattresses

Latex mattresses are a good option if you enjoy foam mattresses but find memory foam a bit too warm or unresponsive. Latex mattresses have a bouncier feel than memory foam, which makes it easier to shift around in bed.

A latex bed can contain natural, synthetic, or blended—synthetic and natural latex mixed—latex. The problem with synthetic and blended latexes is that both wear down quickly and can even off-gas.

Conversely, natural latex comes from the sap of rubber trees and is durable and breathable. Natural latex beds can last upwards of 12 to 15 years with proper maintenance.

Innerspring Mattresses

Innerspring mattresses are very traditional mattresses, having been around since the 1800s. They contain layers of coils and a thin comfort layer, often made from cotton, down, polyester, wool, or poly-foam.

Coil beds are known for being supportive and breathable. However, since innerspring beds contain contiguous coils, this leads to lots of motion transfer. Not only that, but the coils can squeak and cling together, which can be disruptive late at night. Also, the thin comfort layers aren’t very comfortable, especially if they contain fibrous fills like cotton or wool.

Fancier innerspring mattresses have a pillow top or Euro top, which are extra layers of padding sewn to the top of the mattress. Pillow tops and Euro tops add extra cushioning to increase your comfort at night, but are still prone to going flat or shifting out of place.

Hybrid Mattresses

Hybrid mattresses combine the benefits of both innerspring and foam mattresses.

A hybrid bed contains a coil support layer and a comfort layer thicker than 2 or 3 inches. The comfort layers often contain memory foam or latex, but some hybrid beds feature poly-foam. Foam comfort layers provide lots more pressure relief than typical pillow tops or Euro tops.

In innerspring beds, there are contiguous coils, meaning the coils are connected. While this is cheap to produce, it also leads to noise, coils breaking, and motion transfer.

However, hybrid mattresses contain pocketed coils, meaning the coils are separate and wrapped in a lightweight fabric. This promotes close-conforming support, minimal noise or motion transfer, and less chance of coils breaking.

Sleeping Positions

Although knowing the type of mattress you want is one of the first steps to finding a bed, knowing what mattress firmness you need is another important thing to consider.

Choosing the right mattress firmness level comes down to your sleeping position as it affects the amount of cushioning you need.

Side Sleepers

Side sleeping is one of the healthiest sleeping positions. It’s good for your breathing, digestive system, blood circulation, and is even a safe position for pregnant women to sleep in.

Despite being so healthy, the wrong mattress firmness can lead to pressure build-up and pain. Memory foam mattresses are great for relieving pressure, which is why many side sleepers enjoy them.

When sleeping on your side, it’s important to have a bed with adequate cushioning for your shoulders and hips. The best mattresses for side sleepers are soft, medium-soft, or medium memory foam mattresses.

Back Sleepers

Back sleeping is another healthy sleeping position, especially for keeping your spine neutral. It may be uncomfortable for some sleepers at first but is great for your back and neck.

Mattresses for back sleepers should be medium-firm or firm memory foam mattresses. Firmer beds support your back and spine, prevent sinkage, all while providing enough cushioning to stop lumbar back pressure build-up.

Stomach Sleepers

Frankly, stomach sleeping is not the best sleeping position. It’s hard on the lower back, can strain your neck, and can make breathing difficult.

If possible, we recommend switching to side or back sleeping as both are worlds better for you compared to stomach sleeping. However, permanently switching sleeping positions isn’t easy.

If you’re struggling with switching sleeping positions, we suggest using a firm memory foam mattress in the meantime. Firmer beds prevent your hips from sinking—taking your spine out of alignment—and reduce your chances of pain.

Combination Sleepers

It’s rare for a person to sleep strictly in one position throughout the night. Plenty of us enjoy switching positions and moving around at night, but if you do this, you’ll need a mattress built to support multiple positions. Mattresses for combination sleepers are often medium because they offer a balance of cushioning and support to suit different positions throughout the night.

Warranties, Sleep Trials, and Return Policies

When buying a mattress, a brand’s warranty, sleep trial, and return policies are often a person’s utmost concern to ensure they’re getting the best deal and care from a brand.

Reading reviews is also helpful so you can learn about other shoppers’ experiences and decide if that memory foam bed is right for you or if that brand is worth buying from.

Warranties

Warranties are written guarantees from a manufacturer, ensuring they will repair or replace a product. In terms of mattresses, manufacturers cover workmanship defects and sags.

Most mattress warranties last somewhere between 10 to 20 years, though some brands even offer lifetime warranties. During the warranty period, a manufacturer will offer to repair or replace your damaged mattress for free or for an agreed-upon charge.

Sleep Trials

Sleep trials are extended periods where buyers can test their memory foam mattress out at home. They’re especially useful when online shopping because then you can try your mattress out risk-free and can return it easily if needed.

Most sleep trials for memory foam mattresses last between 30 to 365 days. We suggest looking for a sleep trial that’s at least 30 to 60 days so you have sufficient time to adjust to your new bed and decide if you truly like it.

Return Policies

With a sleep trial, always comes a good return policy. If the memory foam mattress you choose includes a sleep trial, this means you should be able to return the mattress within the trial period.

Most brands who offer sleep trials offer free and easy returns, which may include them picking up the old mattress for you, giving clear instructions on how to dispose of your mattress, and more.

Companies that don’t offer sleep trials usually have 30-day return policies. However, 30 days isn’t always enough to adjust to a new bed. Not only that, but companies who don’t have sleep trials usually expect you to return the mattress unused and still properly packaged, so you won’t get the chance to try the bed in the first place.

For this reason, always go with a company that offers sleep trials.

How many inches should a memory foam mattress be?

Regardless of the type of mattress you have, we recommend adults choose at least an 8-inch mattress for nightly usage—and that’s the absolute minimum mattress thickness.

The most comfortable mattresses are typically between the 10 to 14-inch range, so that’s the best range to stick within for your memory foam bed.

What is the average cost of a full size mattress?

The price of mattresses varies based on the type of mattress and its size. The typical price of a full size mattress is usually between $500 to $1500. You can find full size beds for cheaper than this price point, but they’re often made with cheaper materials and break down quickly.

Can a couple share a full size mattress?

While you may be able to squeeze two adults on a full size mattress, it definitely won’t be comfortable.

Full size mattresses are designed to give single sleepers room to stretch out, not couples. Considering a full size mattress is only 54 inches wide, if you try to fit on a full size bed with your partner, you’ll both only have 27 inches of width to yourselves, which is less than you would on a twin bed.

We recommend that couples use queen beds or bigger so both sleepers have ample space.

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

No, box springs are solely usable with innerspring mattresses. You should avoid using a box spring with a memory foam mattress as it can potentially harm your mattress and voids some mattress warranties.

Instead of using a box spring with your memory foam mattress, we recommend using bed slats, solid foundations, platform beds, or adjustable bases.

What is the difference between a foam mattress and a memory foam mattress?

Something important to know is that while all memory foam mattresses are also foam mattresses, not all-foam mattresses are memory foam mattresses. A foam mattress is an all-encompassing term to describe memory foam, latex foam, and poly-foam.

If a brand is solely promoting their mattress as “foam,” it’s safe to assume that the bed is poly-foam. Poly-foam is cheaper than memory foam or latex foam, but not as comfortable or as high-quality. If a brand was selling memory foam or latex, they’d be sure to state so.

Conclusion

You can find countless full size memory foam mattresses on the market, but they’re not all the same. Choose a full size memory foam mattress based on your sleeping position, whether or not you share a bed, and if you tend to get hot at night.

We hope our guide has given you all the information you need on your hunt for a full size memory foam mattress. If you’re ever unsure, always go for a bed with a hassle-free sleep trial, so even if that bed doesn’t work for you, it’s easy to make an exchange.
