Sleep Doctor’s Pick
Sleep Is the Foundation Memory Foam Mattress Topper
Material 2″ memory foam
Firmness Medium (5)
- Perforated foam core promotes airflow
- Cooling gel infusion helps offset heat retention
- Cover composed with a breathable cotton top panel
- Only available in full, queen, and king sizes
- Foam may emit strong off-gassing odor for the first few nights
Memory foam toppers can be a great investment if you want extra cushioning for your mattress or frequently wake up feeling sore or stiff, but these toppers also tend to retain heat and sleep on the warmer side. With this model from Sleep Is the Foundation, you get the best of both worlds. A solid foam core ensures close, even contouring to soothe achy joints and pressure points along the spine, but the foam is ventilated to promote airflow and infused with cooling gel that dissipates heat. A cover with a top panel made of breathable cotton seals the deal.
How Does It Feel?
The topper has a medium (5) feel, striking a nice balance between close contouring and steady support. This creates a cradling, cloud-like effect without too much sinkage or body-hugging. At 2 inches thick, the topper has a lower profile. This makes it best suited to mattresses with light to moderate wear. If your mattress is heavily indented but you aren’t ready to replace it, we recommend a topper that’s 3 to 4 inches thick.
The cover features a cotton top panel and polyester bottom panel. The former is soft and breathable, while the latter is designed to be slip-resistant. Thick, adjustable straps in each corner secure the topper to your mattress for added stability.
Why We Like It
This topper checks all of the important boxes for a memory foam model and sleeps cool to boot. Our testers were impressed with how well the foam resists heat buildup. The close, even contouring also made the topper popular among side sleepers on our team, as well as those with frequent or chronic shoulder, back, or hip pain. The foam’s motion-isolating qualities may be helpful for couples with overly responsive mattresses.
The corner straps are notable for their adjustable buckles. Many competing models use elastic straps, which are effective at first but can easily stretch out over time. The buckles also allow you to use the topper with most mattress profiles. We noticed very little slippage when testing the topper, even during position changes and tossing-and-turning simulations. You may notice some harsh off-gassing odor when the topper is new, but we found the smells should completely dissipate within a couple days. Placing the topper in a well-ventilated room can expedite this process.
Full, queen, and king sizes are available for the topper. Standard ground shipping is free of charge for all orders within the contiguous U.S. You may return the topper unopened and unused within 60 nights of delivery and receive a full refund. If the topper has been opened or used, you can return it for store credit equivalent to the original sticker price.
ViscoSoft Active Cooling Copper Topper
Material 2″ copper-infused memory foam 2″ copper-infused polyfoam
Firmness Medium (5)
- Infused memory foam is designed to draw on copper’s natural cooling properties
- Provides a good combination of pressure relief and support
- Adjustable elastic straps hold the topper in place
- Stomach sleepers over 230 pounds may need a firmer topper
- Lack of bounce limits ease of movement
The ViscoSoft Active Cooling Copper Topper is a 4-inch topper with a medium (5) firmness level. With 2 inches of copper-infused memory foam atop 2 inches of copper-infused polyfoam, it offers the contouring and motion isolation of foam while employing copper’s cooling properties to reduce heat retention.
How Does It Feel?
During testing, side and back sleepers found that the ViscoSoft Active Cooling Copper Topper contoured comfortably to their bodies while offering ample support. Stomach sleepers under 230 pounds also gave the topper solid comfort ratings, but those weighing more than that experienced some sinkage and lack of spinal support.
The copper infusions and breathable mesh cover are designed to mitigate foam’s tendency to trap heat, making this topper a good option for hot sleepers who want the benefits of foam. However, it may still retain more heat than a topper made from a more breathable material like latex.
Our testers also found that the topper’s generous 4-inch profile is excellent at isolating motion and muting sound, making it a good choice for couples.
Why We Like It
The ViscoSoft Active Cooling Copper Topper is a versatile mattress topper with a competitive price-point. It offers solid temperature regulation, and most types of sleepers found it comfortable during our tests. Its top layer of memory foam cradles the body to provide targeted pressure relief, and the 2-inch layer of polyfoam provides support to aid spinal alignment.
Copper infused throughout the foam is designed to absorb and distribute body heat. The polyester mesh cover further promotes airflow and is machine-washable. For people concerned about durability, ViscoSoft includes a five-year limited warranty that covers manufacturing defects.
Puffy Deluxe Mattress Topper
Material 2.5″ memory foam
Firmness Soft (3), Firm (7)
- Solid memory foam contours evenly to cushion and cradle the body
- Available in two firmness levels to accommodate different sleepers
- Elastic cover tucks over your mattress like a fitted sheet
- Strong off-gassing odor for the first 48 hours
- Limited options for people seeking mid-range firmness
In your search for a mattress topper, you’ll find models made with solid memory foam are often among the most expensive options. Puffy breaks from that trend with the Deluxe Mattress Topper, which showcases the most appealing qualities of memory foam without the steep price tag. You can also choose from two firmness levels based on your needs and preferences.
How Does It Feel?
Our team tested both versions of the Deluxe Mattress Topper. The soft (3) model contours very closely, creating a cloud-like surface with deep cradling for the torso and hips. Side sleepers up to 230 pounds enjoyed this topper, as did our back sleepers under 130 pounds. If you want to make your mattress feel more supportive, we recommend the firm (7) version — this model earned favorable ratings from back and stomach sleepers weighing at least 130 pounds.
The cover is made from a blend of rayon, polyester, and spandex. This breathable, moisture-wicking material effectively offsets heat retention from the foam, so you should be able to sleep cool despite the topper’s deep hug. The cover is designed to be tucked over the corners of your mattress. Pocket depth maxes out at 15 inches, so we recommend measuring your mattress to ensure it’s compatible with the topper. You may remove and machine wash the cover as needed.
Why We Like It
Since the topper measures 2.5 inches thick, it significantly changes the feel of your mattress and is suitable for surfaces with deep impressions and indentations. We also liked the cover with elastic pockets for tucking over the corners of your mattress. This helps keep the topper in place without using a fitted sheet. The foam emits strong off-gassing smells after the topper is unboxed, so you may want to let the topper air out in a well-ventilated room for the first night or two after unboxing.
Puffy offers free ground shipping throughout the contiguous U.S. Your Deluxe Mattress Topper order comes with a generous 101-night trial period. If you choose to keep the topper after the trial ends, it’s further backed by a lifetime warranty against manufacturing defects.
Saatva Graphite Memory Foam Mattress Topper
Material 1″ graphite-infused memory foam, 2″ memory foam
Firmness Medium Soft (4)
- Memory foam cradles the body to relieve pressure
- Graphite infusion is designed to limit heat buildup
- 180-night sleep trial
- May not offer enough support for stomach sleepers over 130 pounds
- Fairly pricey
The Saatva Graphite Memory Foam Mattress Topper has a 3-inch profile with a medium soft (4) feel. Its top layer consists of 1 inch of memory foam that contours the body and is infused with graphite designed to prevent overheating. Beneath that, 2 inches of traditional memory foam add support and contouring.
How Does It Feel?
The top layer of graphite-infused memory foam contours closely to the body to give plenty of cushioning and pressure relief. Our side and back sleepers under 230 pounds gave it the highest overall comfort ratings. Stomach sleepers over 130 pounds were less impressed, noting that they didn’t feel properly supported around the midsection.
Why We Like It
This topper’s design balances contouring and support to accommodate a variety of sleep preferences. Sturdy straps attach to your existing mattress and prevent the topper from moving out of its proper position.
While the price-point is higher than many toppers, it’s competitively priced for a luxury pick. Saatva is well regarded for the quality of its products and offers a lengthy 180-night sleep trial to try this topper out at home.
Best for Side Sleepers
Birch Plush Organic Mattress Topper
Material Talalay latex
Firmness Medium (5)
- Talalay latex resists heat buildup and facilitates cooling
- Delivers pressure relief without the sinking feeling of memory foam
- Made with durable, eco-friendly materials
- Doesn’t isolate motion as well as competing memory foam toppers
- Higher price-point than most other mattress toppers
The Birch Plush Organic Mattress Topper is a latex model with a medium (5) firmness level. All its materials, including latex, wool, and cotton, resist heat retention to promote cooler sleep. The latex also provides a compelling balance of pressure relief and bounce.
How Does It Feel?
The Birch Plush Organic Mattress Topper offers significant pressure relief, especially in areas where side sleepers need it, including the shoulders and hips. However, the surface is more responsive than memory foam and does not tightly hug the body, making it easier to move on the topper.
Why We Like It
The Birch Plush Organic Mattress Topper is suitable for most side sleepers thanks to its mix of bounce and contouring. All of its materials are natural, and the company focuses on sustainable production, making this a good choice for eco-conscious shoppers. In addition, its latex is robust and durable, which helps to make up for the higher price-point. Birch offers a lengthy 10-year limited warranty as well as a 100-night sleep trial.
Best Pressure Relief
Brooklyn Bedding Microcoil Mattress Topper
Material 1.75″ polyfoam, 0.75″ pocketed microcoils, 1.5″ polyfoam
Firmness Medium (5)
- Thick profile significantly improves your sleep surface’s comfort level
- Foam-over-coil construction alleviates pressure without too much sink
- GlacioTex cover is engineered to feel cool at all times
- High potential for harsh initial off-gassing
- Expensive pricing for a topper
A worn, uneven sleep surface can lead to increased pressure buildup in the shoulders, lower back, and hips. If your mattress is on its last leg but you aren’t ready to buy a replacement, the Brooklyn Bedding Microcoil Mattress Topper can help you sleep comfortably in the meantime. Three individual layers and a plush, adaptive feel ensure you’ll wake up without soreness or stiffness in your most sensitive areas, but the microcoil layer also helps to maintain an even surface for your body.
How Does It Feel?
The topper features a top layer of adaptive foam, a microcoil middle layer, and a dense foam base. These three materials create a balanced dynamic. You’ll enjoy deep cushioning on the surface, minimal sinkage beneath your midsection, and sturdy overall support. The microcoils also create some responsiveness, resulting in a light bounce when you get into bed — this helps you move across the surface without feeling stuck.
Another notable component is the cover made of GlacioTex fabric. This material is engineered to dissipate heat on contact and feel cool to the touch at all times. Measuring 3.5 inches thick, the topper has a very high profile compared to competing models on the market today. There are no straps or other fixtures for securing the topper to your mattress, so tucking it beneath a fitted sheet is recommended.
Why We Like It
The Microcoil Mattress Topper was a big hit among our testing team, with especially high marks from side and back sleepers up to 230 pounds, and stomach sleepers under 130 pounds. We were impressed with the balance of cushioning, support, and bounce, which can be attributed to the combination of an adaptive foam surface and underlying coils. Temperature control proved to be another standout quality thanks to steady air circulation throughout the interior and the cooling cover.
Although the Microcoil Mattress Topper is fairly expensive, it may prove a solid investment if you’re losing sleep due to pressure buildup. Brooklyn Bedding offers free ground shipping throughout the contiguous U.S. and includes a 30-night trial for testing the topper in your own home. If you decide to keep it, you’ll also receive a manufacturer’s warranty covering workmanship defects for up to three years.
Best for Couples
Dormeo Mattress Topper
Material Memory foam (top layer), zoned Octaspring polyfoam cushions (bottom layer)
Firmness Medium (5)
- Proprietary Octaspring base layer provides zoned cushioning and support
- Steady airflow reduces heat buildup and helps your sleep surface stay cool
- Available in 11 different sizes
- Noticeable off-gassing odor for the first few nights
- Expensive pricing for a mattress topper
Mattress toppers that sleep cool and reduce back pain are hard to come by because the same materials that effectively alleviate sore spots — such as memory foam and adaptive polyfoam — also tend to trap heat. The Dormeo Mattress Topper is a notable outlier thanks to its support core, which contains proprietary Octaspring foam cushions. Each cushion is zoned to feel firmer beneath heavier areas of your body and softer elsewhere. The result is ample padding for your midsection without too much sink.
How Does It Feel?
The topper has a medium (5) feel and the first layer is solid memory foam, making the surface feel soft and squishy as it molds to your body’s unique contours. Hundreds of Octaspring cushions fill the support layer. Air circulates freely through the springs to offset heat retention and help the interior maintain a cool, comfortable temperature. The knit cover is also fairly breathable. You may remove and machine-wash the cover whenever it needs to be cleaned.
A total of 11 sizes are available for the Dormeo Mattress Topper. In addition to standard mattress dimensions, your options include three RV-friendly sizes, a split king consisting of two twin XL toppers, and a split-head king intended for couples who use adjustable beds that elevate the upper body.
Why We Like It
Our team also appreciates sleep products that break from traditional designs and give us something new — the Dormeo Mattress Topper certainly falls into this category. The Octaspring cushions give this topper a unique balance of contouring, support, and responsiveness. Most of our testers reported little to no sinkage beneath their midsections. Despite solid memory foam on the surface, none of us noticed any bothersome heat retention, either.
The wide size range is another perk, especially if you’re planning to use this topper in a dorm bed or RV, or with an adjustable bed. One thing to keep in mind is that the off-gassing odor is quite strong after you unbox the topper. We recommend airing it out in a well-ventilated room for at least two nights before sleeping on it for the first time.
The Dormeo Mattress Topper is fairly expensive, but may be worth the investment if traditional toppers aren’t relieving your pain and pressure points. Standard shipping is free of charge. Your order includes a 100-night sleep trial, giving you more than three months to sleep on the topper and decide whether it meets your needs. Full refunds are issued for all returns within this time frame, provided you’ve slept on the topper for at least 30 nights.

What Is a Cooling Mattress Topper?
A cooling mattress topper consists of an additional layer placed on top of a mattress that is intended to enhance comfort and temperature regulation during sleep.
Regular mattress toppers can help change the feel of a mattress by making it softer or firmer. They can also be an affordable way to extend the life of a mattress by providing it with a fresh top layer. A cooling mattress topper goes a step further by using materials that are engineered to help resist heat buildup or disperse body heat so that sleepers are less prone to overheating.
Who Should Use a Cooling Mattress Topper?
Cooling mattress toppers are a great choice for hot sleepers or people who live in hot climates. They can also help limit heat retention that can come from sharing a mattress with a partner or pet.
Many foam mattresses trap body heat, which can lead to sweating at night and difficulty sleeping. A cooling mattress topper is designed to counteract this heat buildup and keep the body at a neutral temperature.
Cooling Mattress Toppers vs. Cooling Mattress Pads
While many people use the terms mattress pad and mattress topper interchangeably, there are significant differences between the two. Mattress pads are thin pieces of material placed on top of a mattress to protect it from spills, dust, and allergens. While they can make a bed feel slightly softer or firmer, they don’t substantially change the firmness level of a mattress.
On the other hand, mattress toppers are usually several inches thick and can considerably change the feel and firmness of a mattress. A topper may also contribute to a mattress’ durability by compensating for sagging or indentations.

Best Types of Cooling Mattress Toppers
The best mattress toppers for hot sleepers are constructed from breathable materials that either avoid collecting body heat or disperse heat and allow air to circulate. In some cases, materials are infused with cooling agents engineered for temperature neutrality.
Memory foam is known for its ability to conform to the body and offer cushioning around pressure-prone areas. However, this conforming can limit airflow and allow body heat to collect.
As a result, cooling mattress toppers with memory foam employ multiple approaches to reduce heat retention. Manufacturers often infuse the foam with materials that pull heat away from the body or allow more airflow so that heat can dissipate. Common materials that are infused into toppers include copper, graphite, and cooling gels.
Some toppers use open-cell memory foam. This type of foam is constructed with tiny air pockets that allow ventilation and airflow within the foam. Thanks to this structure, the heat normally trapped by memory foam is more capable of being dispersed and may result in a cooler sleep surface.
Latex is popular for mattress toppers because it offers a nice balance of bounce, support, and pressure relief. Compared with memory foam, latex does not have as much tendency to retain heat. It also doesn’t hug the body as closely. Latex can also have an open-cell structure to permit airflow through the material.
Natural latex is harvested from rubber trees, while synthetic latex is made from petrochemicals. Natural latex is more commonly used in mattress toppers and is often sustainably produced, but it is usually more expensive than synthetic latex.
Polyfoam can be manufactured to have a range of different features and firmness levels. Most often, it provides more bounce and less contouring than memory foam. It may collect heat, but usually not to the same degree as memory foam. Like memory foam, polyfoam is sometimes infused with cooling agents, especially if it forms the top layer of a mattress topper.
Climate Control Technology
Some mattresses use special technology to control the temperature of the sleep surface throughout the night. These toppers usually have internal channels for air or water. An attached device tracks temperature levels and can pump hotter or cooler air or water through those channels to adjust the bed’s temperature. A compatible smartphone app is often recommended to set the desired temperature.
Many of these advanced toppers offer the ability to set each side of the bed to a different temperature. While these products can significantly reduce overheating, they are normally much more expensive than traditional mattress toppers.
Picking the Right Cooling Mattress Topper for You
The best cooling mattress topper for you depends on a number of factors, including your weight, sleeping position, and personal sleep preferences. Depending on their design and materials, mattress toppers can alter the firmness of your mattress, add contouring, or provide additional bounce. Think of a topper as an extra comfort layer that can optimize the bed for your needs.
Factors to Consider in a Cooling Mattress Topper
To choose the best cooling mattress topper, consider each component of the topper in relation to your unique needs and preferences.
- Cooling materials: Some mattress toppers use naturally cooler materials like latex, while others infuse memory foam or polyfoam with a cooling agent such as gel, graphite, or copper.
- Firmness: The ideal firmness of a mattress topper usually depends on the sleeper’s personal preferences, sleeping position, and weight. Stomach and back sleepers usually need a firmer mattress topper than side sleepers. People who weigh over 230 pounds normally get better support from toppers that are at least medium firm.
- Support: A mattress topper should provide ample support to promote spinal alignment. Support needs vary from sleeper to sleeper according to weight and sleeping position.
- Pressure relief: This refers to how well the mattress topper cushions sleepers to relieve tension and impact. Generally, the more evenly the topper conforms to the body, the more effective the pressure relief.
- Thickness: Since a mattress topper adds height to a mattress, it’s important to consider whether it could make a mattress too thick for a standard fitted sheet. Thicker toppers are not always better, since a topper’s firmness and performance often depends more on its materials than its thickness.
- Motion isolation: Couples or those who sleep with pets may want to prioritize motion isolation so that movement on another part of the mattress doesn’t wake them during the night. Mattress toppers, especially ones made with memory foam, tend to offer the best motion isolation.
- Durability: A topper’s durability varies based on the materials and quality of construction. On average, foam toppers last three to five years, while latex toppers often last longer.
- Cost: Cooling mattress toppers span a wide price range, from under $100 to well over $1,000. Most shoppers can find a quality topper that meets their needs in the range of $200 to $500.
How Firm or Soft Should a Cooling Mattress Topper Be?
Mattress toppers can make a bed feel softer or firmer. Ideally, a bed should be soft enough to cushion the body, but it should not sag excessively. Finding the right balance in a mattress and topper can promote healthy spinal alignment.
Optimal firmness depends largely on a person’s sleeping position and weight. To avoid sinking too deeply into a mattress, people with a higher body weight generally need a firmer sleeping surface.
|Side sleepers generally prefer a softer bed with more significant contouring that can cushion the hips and shoulders. Most side sleepers over 230 pounds fare best with at least a medium (5) firmness level to prevent sinkage that can cause heat retention and back pain.
|Back sleepers under 130 pounds often find a nice mix of back support and cushioning from medium soft (4) mattress toppers, but those who weigh more may want to consider a topper ranging from medium (5) to firm (7-8) that can resist sagging around the midsection.
|Stomach sleepers generally need a firmer bed that prevents the abdomen from sinking and pulling the spine out of alignment. In most cases, this means a topper between medium (5) and firm (7-8) depending on body weight and comfort preferences.
Do Cooling Mattress Toppers Really Work?
Cooling mattress toppers can be effective at dispersing body heat so that it doesn’t collect around the body. However, a topper’s performance depends on its materials, design, and temperature regulation features.
Materials like latex, which can resist heat buildup, tend to work best for cooler sleep. Memory foam can be engineered to reduce heat retention, but if it closely hugs and wraps around the body, some heat will inevitably become trapped. Many cooling mattress toppers come with sleep trial periods so that you can test them out and return them if you aren’t satisfied.
Can Cooling Mattress Toppers Help With Night Sweats?
Cooling mattress toppers may help alleviate night sweats by helping to regulate body temperature throughout the night. If a topper enables better airflow around the skin, it can support the body’s ability to cool itself down.
That said, night sweats have many potential causes, some of which may persist even when using a cooling mattress topper. People with severe night sweats should consult their doctor about the most appropriate way to get relief.
What Else Can You Do to Stay Cool at Night?
While cooling mattress toppers are one useful way to avoid sleeping hot, there are other steps you can take to stay cool while you sleep.
- Try a mattress with better temperature regulation: In general, innerspring, hybrid, and latex mattresses are less likely to sleep hot than standard foam mattresses. If you’re still sleeping hot after purchasing a cooling mattress topper, it might be time to consider a cooling mattress.
- Use pillows and bedding made from breathable fabrics: Pillows and bedding can trap heat, so it’s important to use breathable sheets and cooling pillows that maintain a comfortable temperature while you sleep.
- Keep your room cool: Take steps to make sure your sleep environment is at the optimal temperature for sleep. This may involve using air conditioning or fans, opening windows to facilitate ventilation at night, or remembering to keep blinds closed during the heat of the day in the summer.
