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, and is secured with elasticized straps or a skirt much like a fitted sheet. Not only does a mattress pad let you customize the feel of your mattress, but it also adds a layer of protection.

While a mattress pad does not necessarily change the overall firmness of your mattress, it can change certain qualities like temperature regulation. A cooling mattress pad actively or passively regulates temperature and prevents 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.

We’ll cover our top picks for the best cooling mattress pads and what to look for when shopping for one. We’ll also break down what type of cooling mattress pad is best, along with answers to frequently asked questions.

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, the Chili Ooler Mattress Pad 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 Ooler Mattress 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 Ooler Sleep System 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 Ooler Sleep System has been shown to improve sleep quality and reduce sweating for hot sleepers.

Chili offers a 30-night sleep trial for the Ooler Sleep System, though the customer is responsible for any shipping costs in the event of a return. The company covers the Ooler Sleep System with a 2-year limited warranty.

How to Choose a Cooling Mattress Pad


There are multiple types of mattress pads, which can make choosing the best cooling mattress pad somewhat overwhelming. Understanding what you are looking for will help narrow down the search. There are several factors for shoppers to keep in mind, which we will break down here. This includes the cooling properties of the mattress pad, how it performs, and what price point you have in mind. Shoppers will also want to consider what they want to change about their current mattress.

What to Consider When Purchasing a Cooling Mattress Pad

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.

  • Cooling Properties: The main reason for purchasing a cooling mattress pad is to prevent overheating and stay comfortable throughout the night. Some mattress pads draw heat and moisture away from the body. Others actively cool the mattress surface. A mattress pad with active cooling properties often circulates air or water to cool down the surface of the bed. These types of mattress pads can be set to a specific temperature with a control unit, remote, and/or smartphone app. Passive cooling properties mean the mattress pad is made with breathable materials that dissipate heat. Conductive materials like copper, gel, and phase change materials draw heat away from the body for a cooling feel. These types of mattress pads do not allow you to customize the temperature of the bed.
  • Price: Like mattresses, mattress pads are available at various price points. Setting a budget before shopping can help customers narrow down their choices. Natural and organic materials are often more expensive than synthetic materials, but they may have a longer lifespan. Pads that incorporate technology or a complex construction can be more effective, but also more of an investment.
  • Sleeping Position: Sleeping position affects how much pressure relief a person might need. It also impacts mattress firmness and overall support. A mattress pad does not change a mattress significantly, but it can offer additional cushioning. Side sleepers may opt for a thicker mattress pad to soften the mattress at their shoulders and hips, while back and stomach sleepers may prefer a firmer sleeping surface.
  • Quality Materials: The quality of materials used in a mattress pad determines how durable the mattress pad is. This can also affect how well the mattress pad regulates temperature. High-quality, natural materials like wool and cotton wick away moisture and heat. A mattress pad also protects the mattress, so a high-quality pad can further extend the life of the mattress. Investing in quality materials means shoppers will not have to replace the pad as often.
  • Firmness Level: Mattress pads are not very thick, so most will not alter the firmness level of the mattress. Some cooling mattress pads have wool or cotton padding, which can add softness to the mattress. Others are thin fabric covers that simply act as mattress protection. Shoppers who want to change the firmness level of their mattress may want to consider a mattress topper instead.
  • Thickness: Mattress pads are thinner than mattress toppers. Most mattress pads are less than one inch thick, which adds some height to the mattress. The mattress pad sits between the mattress and the fitted sheet. Keeping the mattress height in mind is important when purchasing sheets, as mattresses that are more than 12 inches tall will likely need deep pocket fitted sheets. Some mattress pads are ultra-thin and do not affect the thickness of the mattress at all.
  • Pressure Relief: Soft, thick mattress pads can cushion pressure points. Pressure often builds in the shoulders and hips, especially for side sleepers. Most mattress pads will not dramatically alter the amount of pressure relief a mattress provides. Those who want additional pressure relief may consider using a memory foam pad or topper.

Which Type of Mattress Pad is Best at Cooling?

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

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

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.

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

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

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.

Cooling Mattress Pad FAQ

  • How do cooling mattress pads work?

    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.

  • How do you wash a cooling mattress pad?

    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.

  • Who should buy a cooling mattress pad?

    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.
