“The quality of the bed we sleep on plays a critical role in our overall sleep quality,” says Dr. Peter Polos, MD, PhD, FCCP, FAASM, sleep medicine specialist, and sleep expert for Sleep Number. And while no one size—or type of material—fits all, for the ultimate body-hugging comfort, you can't go wrong with a memory foam mattress.
Over the last five years, we've spent hours researching and testing mattresses, evaluating quality, comfort, materials, and overall value. Our top pick for most sleepers is the Casper Original Mattress, a breathable, sink- and sag-resistant mattress that provides targeted spinal support.
Here are the best memory foam mattresses.
Casper Original Mattress
Multiple ergonomic zones
Top layer of breathable foam
Initial odor can be strong
Over the years, Casper has become one of the best-known and reputable brands in the bedding industry. And anyone who tries the Casper Original Mattress will understand why. This memory foam mattress features three layers: a supportive base layer designed to prevent sinking and sagging; a middle layer of memory foam with three ergonomic zones to align the spine and relieve pressure; and a top layer of perforated breathable foam that reduces heat and promotes airflow.
The mattress comes in a compact box for easy delivery and is ultra-simple to set up, too. Once you take it out of its box, it expands and is ready to sleep on within minutes. While some say the mattress emits a strong odor that lingers for a bit too long afterwards (sometimes for months!), most rave about the super-soft, body-hugging comfort. And if you don’t like it, you’re in luck. Casper not only offers a 100-night trial complete with a full refund if you don’t like it, but it also includes a 10-year warranty, should anything go wrong.

Runner-Up, Best Overall
Saatva Loom & Leaf Mattress
Cooling gel-infused foam
Antimicrobial top layer
The Saatva Loom & Leaf Mattress is undeniably expensive, but it’s intended to be a luxury option. It’s constructed for the ultimate comfort with high-quality materials, and it’s backed by an extensive 365-night home trial and a generous 15-year warranty to help you justify the purchase. You can also get white glove delivery to have it placed exactly where you want it—no effort needed on your part.
The six-layer mattress couldn’t be more comfortable. It’s made with pressure-relieving memory foam and high-density foam layers that will win you over, thanks to the contouring support. It also has a layer of breathable, gel-infused foam, so sleepers will stay cool even on the hottest nights. What’s more, the quilted organic cotton cover features a botanical antimicrobial treatment to help your mattress stay nice and clean throughout the years. Also nice: The foam is CertiPUR-US certified, meaning it's free from harsh chemicals.

Signature Sleep Memoir 12-Inch Memory Foam Mattress
Eco-friendly and CertiPUR-US-certified
Includes soft cover
Lower price point
May be too firm for some sleepers
Not as many sizes available
Just because you’re on a budget doesn’t mean you can’t get an ultra-comfortable memory foam mattress. The more wallet-conscious will love the Signature Sleep Memoir, since it offers balanced support and is crafted with CertiPUR-US-certified foam. The mattress has none of the bad stuff—harmful PBDEs, ozone depleters, mercury, or lead.
All you get is the good stuff, including a 4-inch layer of memory foam and eight inches of high-density foam for a total of 12 inches of glorious support. While you sleep, the mattress has just enough give to mold to your body’s natural shape, minimizing pressure and distributing weight as evenly as possible. It’s worth noting that it’s a little bit firmer than other options, so it’s most ideal for back and stomach sleepers.
And while this memory foam mattress does come with a soft, breathable cover, it comes in limited bed sizes—you’ll have to look elsewhere if you need a split or have a California king.

Leesa in a Box Mattress
Cool for hot sleepers
Easy to adjust to
Not ideal for stomach sleepers
The U.S.-made Leesa Original Mattress is composed of three layers of top-quality LSA200 foam—a foam that has microcell structure technology to help promote airflow. It’s perfect for sleepers who tend to run hot or even sweat during the night.
Despite this cooling effect, the Leesa doesn’t sacrifice whole-body comfort in any way. The mattress actually adapts to your specific body type, providing enhanced pressure relief that’s perfect for athletes or anyone who suffers from muscle tension or even pain.
Overall, this mattress is a good choice for most sleepers, though stomach sleepers in particular may find the ultra-plush sleep surface a bit too soft, since it can create bowing in the back that eventually leads to back pain.
A bonus worth noting: The company donates one mattress for every 10 sold.
"In our experience, back sleepers found it more comfortable than stomach or side sleepers—the latter who generally need softer support around the curve of their hips and shoulders. However, our lone stomach sleeper thought it did prevent their back from bowing, which often happens with memory foam mattresses."—Stacey L. Nash, Product Tester

Best Mattress Topper
LUCID 4 Inch Ventilated Memory Foam Mattress Topper
Thicker than many toppers
Airflow-enhancing ventilation channels
Great for back sleepers
Too plush for some sleepers
If you don’t want to invest in an entirely new mattress but love the idea of transitioning to memory foam, the LUCID 4-Inch Ventilated Memory Foam Mattress Topper is a great, budget-friendly option. At 4 inches tall, it’s undoubtedly substantial—almost half that of some full mattresses.
It’s made well, too. It’s constructed of memory foam that’s infused with an effective cooling gel complete with evenly spaced ventilation channels that excel at improving airflow and regulating temperature. The result: Sleepers who run hot will stay cooler, and therefore more comfortable, at night. And though it’s relatively plush, this topper is also proven to help some sleepers—particularly back sleepers—rest pain-free, since the foam aligns the spine by supporting the natural curves of the head, neck, and shoulders.

Tuft & Needle Original Adaptive Foam Mattress
Great for stomach sleepers
Adaptive, weight-distributing foam
Takes up to 72 hours to expand fully
Too firm for some
Whether you prefer your mattress on the firmer side or are a stomach sleeper who needs the firmness to prevent painful back bowing, the Tuft & Needle Original Mattress is a great choice. The memory foam mattress is specially designed to absorb pressure and accommodate the natural curves of the body for even weight distribution and proper alignment. And though it’s firm, it offers just enough bounce, so you won’t feel like you’re sleeping on a board. (If you want something truly plush, look elsewhere!)
Like other great mattresses, it’s also constructed of a special adaptive foam that has cooling properties, thanks to materials like gel and graphite. Of course, you’ll have to try it for yourself—and you can, thanks to a 100-night sleep trial and a 10-year limited warranty. Just don’t make any rash decisions. Since this mattress comes wrapped up in a box, it can take up to 72 hours for it to fully expand and for any potential odors to go away.

LUCID 12 Inch Gel Memory Foam Mattress
Good for couples
Sizing is slightly off
It can be a tall order to find a mattress that works for both you and your partner—particularly if you sleep in different ways or run at different temperatures. But the Lucid 12 Inch Gel Memory Foam Mattress is an excellent selection to solve this dilemma, since it provides a medium-firm feel (not too hard or too soft). It also features special isolated motion transfer, so you won’t feel your partner tossing and turning at night. What’s more, the top-selling mattress offers three inches of gel-infused memory foam that wicks away heat and promotes airflow.
The mattress is also a good choice for anyone who experiences neck, back, or hip pain, since it's adept at adjusting to the various pressure points in your body. This is all thanks to a base layer of foam that provides deep, structural support and spine alignment.
Some users say the sizing is ever-so-slightly off, leaving small gaps between the bed frame and the mattress. If you can get past that, you’ll love the feel of the mattress, plus nice bonuses like a naturally hypoallergenic removable cover.

Best for Back Pain
Zinus Cooling Green Tea Gel Memory Foam Mattress
Great for pain relief
Suitable for all sleepers
Too firm for some
This mattress is definitely firmer than most memory foam mattresses, but that’s what makes it so great for anyone who struggles with back pain. The Zinus Memory Foam Green Tea Mattress is constructed with three different layers of foam (memory foam, comfort foam, and high-density support foam), so that regardless of sleep position, it will conform to the body and alleviate pressure in key areas like your back, neck, and shoulders.
The foam is also CertiPUR-US Certified and infused with green tea extract and castor seed oil to help stave off bacteria and unseemly odors. Considering this and its ability to reduce pain, keeping you more comfortable at night, this mattress offers an exceptional value. Just make sure a firmer memory foam mattress is what you’re really after; otherwise, you may find it a bit too hard.

Best for Side Sleepers
Allswell Luxe Hybrid Mattress
Hybrid coil-and-foam construction
Built-in plush topper
Some say it’s too plush
Side sleepers in particular will appreciate the Allswell Luxe Hybrid, thanks to a medium-firm feel that conforms to the body but doesn’t allow you to fully sink in. It’s also a great option for couples who can’t quite agree on how plush or firm their mattress should be, since the Individually wrapped coils offer the firm support and springy feel some are looking for, while the top layer of performance memory foam provides pressure-relieving softness.
The Luxe Hybrid mattress is also expertly designed to feel cool to the touch, so hot sleepers will be more comfortable throughout the night. What’s more, the mattress is CertiPUR-US certified—it’s entirely free of harmful chemicals like lead, mercury, and phthalates. Allswell also offers a 100-night risk-free trial and a 10-year warranty to help you feel extra-confident in your purchase.

Sleep Number 360 M7 Smart Bed
Adjustable for maximum comfort
Many sizes available
Longer warranty than most
This may be a seriously expensive mattress, but there’s a reason Sleep Number charges as much as it does for their mattresses—the 360 M7 Smart Bed in particular. This highly researched bed utilizes some of the most advanced smart technology available in mattresses to offer an exceptionally premium sleep experience.
The bed is available in a wide range of sizes, and you can customize the whole thing from start to finish. Once you select a size, move on to a base option (or opt for mattress only, if you prefer!), then add extras like a protection pad or a set of cooling sheets.
The mattress itself is fully adjustable, too. In fact, thanks to the integrated technology, it responds to your movements and automatically adjusts firmness on each side—great for couples sharing a mattress. Through the compatible smartphone app, you can even get sleep data the next day, so you can continue to adjust your side of the bed accordingly, eventually settling on just the right option for you. Hot sleepers will also appreciate the cooling properties of this luxe mattress; it works to absorb excess heat and release it as you cool down, to help you sleep better at night.
Worried about making such a massive investment? Sleep Number offers a 100-night trial, plus has a more extensive warranty than most—you’ll get 15 years of protection with your purchase.

For a soft and supportive mattress that most people will love, we recommend the Casper Original Mattress. The layers of foam provide a balanced sleeping surface that’s highly breathable. If you’re on a budget, try the Signature Sleep Memoir 12-Inch Memory Foam Mattress. Though it is much more affordable, it has two layers of foam for a total of 12 inches of support, plus is made with CertiPUR-US-certified materials and comes with a soft, breathable cover.
What to Look for in a Memory Foam Mattress
Type of Foam
“Traditional” memory foam is made up of polyurethane-based viscoelastic foam, but there are a few other types of foam used as well. Plant-based memory foam has become a popular choice for its improved breathability and more eco-friendly manufacturing. Some foams are infused with gel or copper to make them cooler to sleep on.
The density of memory foam, measured in pounds per cubic foot, tells you how well the mattress will support you, retain its shape over time, and reduce motion transfer. High-density foam (6 pounds per cubic foot or more) is the most supportive, firm, and durable. If you want a plush mattress, opt for low-density foam (3 pounds per cubic foot or less), but keep in mind that it will be less supportive.
If you’re a hot sleeper, you may find that a traditional memory foam mattress retains too much heat—look for a mattress with open-cell construction and gel or copper-infused foam to help you sleep comfortably.
How long do memory foam mattresses last?
Memory foam mattresses can last anywhere between seven and 10 years, with seven years being average. There are a few factors that play into this: cleanliness, rotation (or lack thereof), allergy issues, and the presence of pets and children.
How do you clean a memory foam mattress?
You can clean a memory foam mattress in several ways: vacuuming (best for surface level debris or dust), a cleaning solution (diluted fabric cleaner, dishwashing soap, or a mild detergent work best), or spot-cleaning. However you clean, be sure the mattress is completely dry before using or covering with sheets.
How long do memory foam mattresses need to expand?
As soon as you receive your mattress, it's recommended to open it right away to start the expansion process. It typically takes anywhere between four and six hours for the memory foam to expand 90% (and potentially another four to six hours for full expansion). Experts recommend waiting at least 24 hours before laying on it.
What thickness is best for memory foam mattresses?
“A standard thickness can vary anywhere from eight to more than 16 inches,” says Polos. One isn’t necessarily better than another. Rather, the right thickness for you depends on your sleeping position and your sleep needs. If you tend to need more support, look for a mattress on the thicker side.
Are there different types of memory foam?
There are a few different types of memory foam on the market, and they can target different types of sleeping issues that people have at night, says Polos. “Memory foam comes in traditional, gel, and plant-based.” They also come in a variety of densities, composed of several layers of materials, from simple one-layer to complex arrangements, he explains. Like thickness, the type of memory foam you choose depends largely on your sleep needs. For example, if you run hot, you’ll want to look for a memory foam mattress that contains a cooling layer. “As with any bed, you should research and try a variety of them before purchasing one,” says Polos.
