If you love almost everything about your mattress but want to make small changes to customize your sleep environment, a mattress pad is worth considering. A mattress pad is a thin layer that sits on top of your current mattress. A cooling mattress pad actively or passively regulates temperature and prevents you from sleeping hot. Some are made with breathable materials, like cotton or wool, while others are infused with gel to draw heat away from the body and dissipate moisture. Certain styles use technology to actively cool down the surface of the mattress.
Our team has tested dozens of cooling mattress pads and determined which models are worth purchasing. Side, back, and stomach sleepers across multiple weight groups put our top picks to the test, analyzing each one for comfort, value, and temperature regulation.
Along with the featured cooling mattress pads in our top picks, we’ve also included a comprehensive buyer’s guide. This section tells you what to look for and what to avoid when shopping for a cooling pad. We’ll also break down how cooling mattress pads work, answer frequently asked questions, and help you choose the right style for your sleep preferences.

The Slumber Cloud Nacreous Mattress Pad stands out with its proprietary Outlast technology, which is engineered for optimal temperature regulation. Outlast is a phase change material (PCM), which has the ability to absorb, store, and return heat.
The pad’s fabric lining is engineered to reduce heat and moisture buildup when you’re too hot, but it also releases heat if you start to get cold. Additional temperature-regulating technology is added to the top cover. The PCM technology may appeal to couples with differing temperature preferences, as the mattress pad is designed to adjust to each person’s unique needs.
The pad is available in the six standard mattress sizes, as well as split king. Shoppers can choose between blue and white, which differ slightly in fabrication. The blue model’s top fabric consists of 40% Outlast viscose and 60% cotton, while the top panel of the white pad features 100% lyocell. Both compositions are effective at regulating temperature.
The pad features a small amount of polyester fiberfill padding for greater breathability, without changing the overall feel of your mattress. Its elastic skirting has a 360-degree grip to ensure a snug fit, and the pad will fit mattresses with profiles between 5 inches and 20 inches.
The Nacreous Mattress Pad is hypoallergenic and machine-washable. It comes with a 60-day trial, and Slumber Cloud offers free shipping for all U.S. orders.

Unlike mattress pads that passively regulate temperature, chilisleep’s OOLER Sleep System with Chilipad Cool Mesh actively customizes the temperature of the bed with a hydronic pad and control unit. This gives sleepers the option of setting a temperature for the bed between 55 and 115 degrees Fahrenheit for personalized comfort.
The hi-loft jacquard knit of the mattress pad has a Tencel lyocell surface for breathability. The pad also features an energy-reflective waterproof polyester bottom. The hydronic pad is 0.375 inches thick and includes 0.125-inch tubing with leak-proof connectors. Water flows through the channels and adjusts the temperature of the pad.
The pad is controlled by an attached unit with a water tank. The control unit has a low profile so it can fit underneath the bed. It auto-cleans with a UV light. There is variable ambient noise, which can be adjusted on the control unit.
The pad can be optimized for one or two sleepers. It is available in sizes half queen, half king, half California king, queen, king, and California king. The half sizes are designed for one sleeper and cover half of the mattress. Whole sizes cover the entire mattress and include two control units. This is beneficial for couples with differing comfort preferences, as each side can be individually adjusted.
The mattress pad pairs with a smartphone app for temperature control, customizable schedules, and notifications. Sleepers can set the Warm Awake feature in lieu of an alarm clock. This option warms the bed slowly to wake you up naturally. The Sleep System has been shown to improve sleep quality and reduce sweating for hot sleepers.
chilisleep offers a 30-night sleep trial for the OOLER Sleep System with Chilipad Cool Mesh, though the customer is responsible for any shipping costs in the event of a return. The company covers the product with a 2-year limited warranty.
Our team is well-versed in a wide range of sleep products, including mattress pads and other types of bedding. Each member brings years of experience and expertise to our hands-on product testing, and we’ve personally evaluated dozens of mattress pads using a comprehensive methodology that incorporates many different design and performance elements. This all-inclusive process ensures every product we recommend has been thoroughly tested.
In order to choose the best cooling mattress pads listed above, we primarily focused on breathability and temperature regulation during our evaluations. However, we also took other factors into account, including quality of materials and design, level of comfort adjustment, the pocket depth of elasticated edges (when applicable), ease of care, and overall value. These top picks received the highest ratings during our tests.
Sometimes, companies use misleading terminology or overstate the features of a mattress pad, which can make it difficult to distinguish fact from fiction. Additionally, every shopper has unique needs and preferences. What works for one person may not work for another.
Focusing on the following features will help narrow down the vast selection and differentiate between a mattress pad that suits your needs, and one that does not.
There are different types of cooling mattress pads available, each of which has benefits and drawbacks. We’ll break down what types are best at cooling here. Keep in mind that mattress pads enhance the features of your current mattress. Additional factors, including bedding, room temperature, and personal preferences, will also determine which mattress pad is best for you.
Memory foam mattress pads react to heat and pressure to conform closely. This can restrict airflow around the body. These pads may also retain heat. This is especially the case for mattress pads made of traditional memory foam. Newer styles of memory foam often have an open-cell structure for better airflow. Memory foam can also be infused with copper or graphite to draw heat away from the body, or gel for additional cooling.
Polyfoam is less conforming than memory foam, which allows for better airflow around the body. There are many types of polyfoam, some of which regulate temperature better than others. Basic polyfoam may still retain heat, but is going to be less restrictive than memory foam. Like memory foam, advanced polyfoam can also have an open-cell structure, or be infused with copper, graphite, or gel.
A cooling gel mattress pad draws heat away from the body. Gel-infused foam dissipates heat and moisture to prevent overheating. Some gel foams are better than others. How well it performs depends on the type of gel used and how it is incorporated into the foam. Heat retention is still possible.
Latex is a natural material made from sap harvested from rubber trees. It is more breathable than synthetic foam and regulates temperature well. There are two types of natural latex: Dunlop and Talalay. Dunlop latex is more dense. Talalay latex is light and breathable, and it is often used to regulate temperature in mattresses. Latex can be aerated to maximize airflow and improve breathability.
Wool and cotton are natural fibers that wick away moisture and regulate temperature. Cotton is lightweight and breathable. It prevents moisture from building up in the mattress pad. This is beneficial for hot sleepers who are prone to sweating throughout the night.
Wool acts as natural insulation. The fibers absorb and retain heat in cooler months, and dissipate heat when it is warmer. This keeps sleepers comfortable throughout the year. Wool and cotton fill can also add softness to a mattress.
Standard mattress pads have two primary functions: to protect your mattress from spills and contaminants, and to slightly improve the comfort level of your mattress. These traits distinguish pads from mattress protectors, which offer stronger protection – most are 100% waterproof – but do not change the feel of the mattress very much. Pads also differ from mattress toppers, which protect the mattress to a minimal extent but will significantly adjust the feel of your sleep surface.
Cooling mattress pads perform a third function by regulating the surface temperature of the mattress to keep you comfortable while you sleep. Every cooling mattress pad has a unique design, but most fall into one of two categories: active cooling or passive cooling pads.
As their name suggests, active cooling pads are designed to actively cool your mattress. Many circulate air or water to maintain a steady, comfortable temperature across the mattress surface. These pads usually have dials or remotes, and may be programmed for specific temperature settings. Some newer models are also compatible with smartphone apps.
Passive cooling pads are constructed from breathable materials that draw heat away from your body without actively regulating the surface temperature. These materials include copper, gel, and phase change material. Breathable shell fabrics like cotton, Tencel, and rayon from bamboo can also enhance the pad’s cooling properties.
Most passive cooling pads can be washed and dried in any household machine. Specific care instructions vary, but these pads should usually be washed in cool or warm water on a delicate cycle and tumble dried on a low setting.
Cleaning instructions may differ for active cooling pads. Some should never be machine-washed or -dried because they contain fragile tubes, electrical parts, and other components that can be permanently damaged if exposed to water. Other cooling pads are washable in household machines, but you may be limited to delicate wash cycles and no-heat dryer settings. If your machine-washable active cooling pad includes a power cord, you should secure it with a rubber band to prevent damage to both the cord and your appliances.
These are general cleaning suggestions, and specific care instructions vary by pad. Whether you choose a passive or active cooling pad, always check the care tag before washing and drying it for the first time.
Some people sleep hot regardless of the season or local climate, and an uncomfortable temperature in bed may impact overall sleep quality. A cooling mattress pad can help maintain a comfortable temperature for hot sleepers and help them rest soundly throughout the night.
Even if you don’t need active or passive cooling to sleep comfortably, mattress pads also improve the feel of your sleep surface and protect the mattress from liquid damage and contaminants. Cooling mattress pads can be a worthwhile investment if you’re looking for bedding with any of these features.
