The Best Cooling Mattress Toppers

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.

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. 

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.

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.

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.

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.

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.

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. 

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
