While a brand-new mattress can be a good idea for those looking to improve their sleep quality, sometimes a mattress topper can be a more cost-effective and simple solution to finding enhanced sleep. Memory foam mattress toppers come in various sizes and designs and at a wide range of price points. Some even use open-cell technology or gel infusions to draw out excess heat and keep you cool.
Here, the best memory foam mattress toppers on the market.
Best Overall: ViscoSoft 3 Inch Gel Memory Foam Mattress Topper
Sizes: Twin, twin XL, full, short queen, queen, king, Cal. king | Material: Gel-infused memory foam, bamboo-rayon cover | Thickness: 3 inches | Care: Removable, washable cover | Warranty: 7 years
Exceptionally plush and comfortable
Comes with a removable, machine-washable cover
Gel-infused foam and ventilated design promote airflow
May require a deep pocket fitted sheet
If you’re looking for the ultimate in plushness, the Viscosoft Select High Density Topper is a solid choice. It features gel-infused memory foam and a ventilated design to promote airflow, distribute body heat, and help keep hot sleepers comfortable. The 3-inch high-density memory foam also helps evenly distribute body weight to relieve pressure points and prevent you from sinking too far into the mattress. One of the thicker options on our list, it's great for side sleepers or those looking for an extra soft sleeping surface.
Our tester especially liked this mattress pad's smart design: it comes with a breathable bamboo-rayon cover that's machine washable, so you can easily keep your mattress topper feeling fresh, clean, and odor-free. It's available in all standard bed sizes.
"After sleeping on it for a few nights, I can confirm that the mattress topper is excellent at regulating temperature. I don’t have a problem with overheating while I sleep, but it does remain comfortably cool through the night."—Theresa Holland, Product Tester
Best Budget: Linenspa 2-Inch Gel Infused Memory Foam Mattress Topper
Sizes: Twin, twin XL, full, full XL, queen, short queen, king, Cal. king | Material: Polyurethane memory foam, gel beads | Thickness: 2 or 3 inches | Care: Spot clean | Warranty: 3 years (limited)
Gel keeps you cool
Range of sizes, including queen short and full XL
On the thinner side
While some toppers can cost the same price as an entire mattress, that’s not the case with this model by Linenspa—even the California King is affordable. But despite its low price, this topper is still high quality, adding a layer of plushness to your bed while also being supportive. It’s made from memory foam infused with gel beads for maximum pressure relief and cooling.
The only downside is that it's just 2 inches thick, whereas most mattress toppers are 3 or 4 inches thick. Linenspa does produce a 3-inch model, though, but it’s slightly more expensive.
Best Splurge: Tempur-Pedic Topper Supreme 3-inch Mattress Topper
Sizes: Twin, twin XL, full, queen, king, Cal. king | Material: Proprietary Tempur material/memory foam | Thickness: 3 inches | Care: Removable, washable cover | Warranty: 10 years (limited)
Filled with the brand's proprietary Tempur material
Can reduce aches and pains
10-year limited warranty
May be too hot for some
The TEMPUR-Topper Supreme is designed to reduce pressure points as you sleep, making your night more restful and ensuring you wake up comfortable. Filled with the brand’s proprietary Tempur material, it offers enough comfort and support to justify the higher price tag. Available in sizes fitting everything from twin beds to California kings, its cover is 98 percent polyester and 2 percent elastane.
Note that this topper can run a bit hot, so if you tend to overheat in your sleep, you might want to leave it to the colder months (or avoid it altogether).
Best Pillow-Top: ViscoSoft 4-Inch Pillow Top Memory Foam Mattress Topper
Sizes: Twin, twin XL, full, queen, king, Cal. king | Material: Gel memory foam, down alternative-fill cover | Thickness: 4 inches | Care: Machine-washable cover | Warranty: 7 years
Plush topper that's good for side sleepers

May be too soft for some
Another pick from Viscosoft, this 4-inch pillow-top topper comes in seven sizes and features 2.5 inches of gel-infused memory foam topped with a 1.5-inch down alternative layer to provide the ultimate upgrade to any mattress. The down topper is covered with a 300-thread-count fabric that’s hypoallergenic and machine washable. It also comes with elasticized pockets that fit mattresses up to 18 inches thick and help keep the topper in place throughout the night.
Best Gel: LUCID 3-inch Gel Memory Foam Mattress Topper
Sizes: Twin, twin XL, full, full XL, queen, king, Cal. king | Material: Gel memory foam | Thickness: 2 or 3 inches | Care: Spot clean | Warranty: 3 years (limited)
Medium-plush topper with 3 inches of supportive memory foam
Vented and gel-infused for cooling
Comes with washable cover
Takes 48 hours to expand
The Lucid Gel Memory Foam Mattress Topper is 3 inches thick and has a medium plush feel, so it’s not so soft that you’ll sink in but just firm enough to give you support. The ventilated design helps promote airflow, and the infused gel material helps regulate your temperature throughout the night. It takes about 48 hours to inflate and comes with a 3-year limited warranty against defects.
Best Thin: Slumber Solutions 1-inch Memory Foam Mattress Topper
Sizes: Twin, full, queen, king, Cal. king | Material: Memory foam | Thickness: 1 inch | Care: Spot clean | Warranty: 3 years (limited)
Offers medium support for those who like a firmer mattress
Takes 48 hours to expand
May have slight odor when unpackaged
If you prefer firm mattresses but are looking for more comfort, the Slumber Solutions Memory Foam Mattress Topper provides just the right amount of support. The 1-inch thick topper is made from 2-pound-density memory foam and offers medium support to keep you comfortable and reduce pressure points.
While it’s not as thick as other options, this topper still provides plenty of support, conforming to your body without the overt softness some sleepers dislike. The material is also temperature-sensitive, using your body heat to mold around individual contours.
Best Cooling: Sleep Innovations 4-inch Dual Layer Gel Memory Foam Mattress Topper
Sizes: Twin, full, queen, king, Cal. king | Material: Gel memory foam, fiber fill | Thickness: 4 inches | Care: Removable, washable cover | Warranty: 10 years
Regulates temperature well
Supportive and comfortable
New smell lingers
For some, the decision to buy a foam mattress topper isn’t based on creating a more plush surface as much as keeping things cool throughout the night. Combining the best attributes of memory foam and fiber-fill, this is the goldilocks of mattress toppers. Each layer is two inches thick, providing both support and plushness all in one. The pillowy top layer is machine washable, and it provides great protection for the memory foam layer. Although, should anything go awry, the memory foam layer has a 10-year warranty).
But the topper’s best attribute is its cooling capabilities. Despite sitting beneath a two-inch layer of fiber-fill, the gel-infused memory foam still works wonders to keep you cool at night, no matter the temperature outside.
Best Firm: Zinus Green Tea Cooling Gel Memory Foam Mattress Topper
Sizes: Twin, twin XL, full, short queen, queen, king | Material: Green tea and charcoal-infused memory foam | Thickness: 1.5, 3, or 4 inches | Care: Spot clean | Warranty: 5 years (limited)
Infused with green tea and charcoal for odor protection and moisture-wicking
No cooling gel
Needs 48 hours to expand to full size
Most mattress toppers aren’t designed to help a soft mattress feel firmer, but that said, some are definitely firmer than others. If you want a medium-firm topper that provides excellent support but not too much extra plushness, opt for this Zinus model. It’s made from two layers of memory foam: the high-density bottom layer provides ample firmness, while the top has green tea and charcoal to help prevent both odor and moisture from forming.
Just keep in mind this denser topper might feel a little hot, as there’s no cooling gel, so it’s better for cold sleepers or cooler climates.
Best Twin XL: Lucid Comfort Collection 3" Charcoal and Aloe Infused Memory Foam Mattress Topper
Sizes: Twin, Twin XL, full, queen, king, Cal. king | Material: bamboo charcoal memory foam | Thickness: 2, 3 or 4 inches | Care: Spot clean | Warranty: 3 years
Infused with aloe and charcoal for odor protection and moisture-wicking
Open-cell memory foam for cooling
Some might find it too soft
Since Twin XL mattresses are most common in college dorm rooms, it’s not a bad idea to get an odor-repelling model. That’s where this Lucid Comfort mattress topper comes in. The 3-inch-thick memory foam not only provides cushioning, support, and cooling—dorm mattresses aren’t known to be the most comfortable—but it is also infused with charcoal and aloe to fight odors. Plus, it’s very reasonably priced (just in case it doesn’t survive a year at school).
Best for Kids: Milliard 2-Inch Ventilated Memory Foam Crib and Toddler Bed Mattress Topper
Sizes: One size | Material: Memory foam | Thickness: 2 inches | Care: Removable, washable cover | Warranty: Not listed
Comes with waterproof, non-slip cover
Aerated for cooling
New smell lingers
First off, a safety warning: infants and young children should never use a soft mattress topper, as there is a risk of suffocation. Be sure to consult your doctor before buying a mattress topper for your older toddler.
That said, if your doctor gives the go-ahead for your child to use a mattress topper, this is the one to buy. Its two inches of hypoallergenic memory foam are perfect for a smaller body, and it comes with a machine-washable waterproof cover to protect the topper against any accidents.
What to Look for in a Memory Foam Mattress Topper
Firmness is perhaps the most important quality of a mattress topper when it comes to proper body alignment while sleeping. “It is recommended to choose the firmness level based on the sleeper’s favorite position. For instance, side sleepers require more of a hug for the protruding body parts. Therefore, they are advised to choose softer mattress toppers,” says Alex Savy, a certified sleep science coach and founder of SleepingOcean. “Back sleepers usually feel the most comfortable on medium, sometimes medium-firm surfaces. And stomach sleepers are recommended to stick to firm toppers. This would help them avoid unwanted curves in the spine.”
The thickness of memory foam mattress toppers usually ranges from 1 inch to 4 inches. A 1- or 2-inch topper will most likely be thick enough to make your mattress more comfortable, allowing you to use the bed for a few more years before replacing it. Thicker mattress toppers are good for side sleepers or anyone who wants a plusher mattress feel.
Memory foam mattress toppers are sold in all standard bed sizes and designed to fit over your existing mattress, so you’ll want to choose the same size as your bed for the perfect fit. Some toppers also come in harder-to-fit sizes, like full XL and short queen.
If you can, choose a mattress topper with a removable and washable cover. The covers are often breathable to help you stay comfortable throughout the night. Covers also help protect your mattress topper from getting dirty since most memory foam products are not washable.
If you’re a hot sleeper, choose a ventilated memory foam mattress topper or one that’s infused with cooling gel—this will help you enjoy the supportive benefits of sleeping on memory foam with less chance of getting overheated during the night.
When purchasing memory foam products, it's helpful to look for options that have been third-party tested for consumer safety. For instance, you can opt for a memory foam mattress topper that is CertiPUR-US certified to be free of potentially harmful chemicals.
What's the difference between a mattress topper and a mattress pad?
They’re both similar in that they’re a soft cushion designed to sit atop a mattress, but they’re a bit different in function. “Mattress pads are usually much thinner than toppers. A pad can only offer slight comfort changes, while a good foam topper may alter the feel of one’s mattress, plus aid support and tension alleviation,” says Savy.
How do you clean a memory foam mattress topper?
While you should always defer to a manufacturer’s instructions regarding cleaning, most mattress toppers can be cleaned with one simple technique. “Sprinkle baking soda over the topper," says Robert Pagano, co-founder of Sleepline. "Add water sparingly because if you add too much, you'll need to let it dry in the sun and have kids or pets off-limits for 24 hours before re-use.”
To help protect your mattress topper, you can use a machine-washable cover.
Should you flip a mattress topper?
It depends on your specific mattress topper. Some are designed with a clear top and a clear bottom due to the different layers of material. For instance, some cooling mattress toppers only have cooling gel on the surface, not all the way through.
If your mattress topper is reversible, you can rotate and flip it to have it wear down more evenly. But every topper has its limits. “If the mattress topper seems saggy or deformed, flipping it won't help. It may be time for a new one,” says Pagano.
How do you dispose of a memory foam mattress topper?
Memory foam is a form of polyurethane (a type of plastic), so instead of letting it sit in a landfill, recycle it or upcycle it if possible. Contact your local recycling facility to see if they have any programs for memory foam mattress products, donate gently used toppers, or see if you can make a DIY project, such as throw pillows.
