We updated this guide in June 2022 to ensure all products tested and vetted by the Good Housekeeping Institute Textiles Lab were in stock and reflected current prices.


If your mattress is not feeling as comfy as it used to, a mattress pad or mattress topper is an easy fix. For many, mattresses can trap in heat causing night sweats, especially during warm weather. Cooling mattress pads can make your mattress feel cooler and plusher. But what's the difference between a mattress pad and a mattress topper anyway?

  • Mattress pads add a cozy top layer with a bit of cushioning.
  • Mattress toppers are usually thicker and offer more cushioning.

    At the Good Housekeeping Institute Textiles Lab, we make it easy to build your dream summer bed to get your best sleep. These mattress pads and toppers from brands we love have innovative features for ultimate cooling. For hot sleepers, our Textiles pros recommend looking for cooling technologies like Outlast, which stores and releases body heat as needed, and 37.5, which works by wicking away sweat before it forms. For your ideal, cool bed, make sure to have a cooling comforter, cooling blankets and cooling sheets, along with your new cooling mattress pad. We chose these picks ahead based on our categorical expertise and decades of testing bedding.

    • Outlast technology
    • Multiple color options
    • High marks from testers for staying in place

    SlumberCloud offers a traditional-style mattress pad that goes on your mattress like a fitted sheet — and it uses Outlast technology to keep you cool. Outlast absorbs heat when you get overheated and releases it when you are too cold, preventing night sweats in the first place. Using a mix of Outlast viscose and cotton fabric on the top, it has a soft feel while the pad is made of Lyocell to wick away moisture for extra cooling. Our testers raved about this pick's cooling capabilities with one saying it "substantially helped regulate my temperature and kept me cool through the night."

    If your mattress has lost the soft, supportive feel you love, opt for a thicker mattress topper that will transform your sleeping experience without having to purchase a whole new mattress. This pick from ViscoSoft has two-inch, three-inch and four-inch thickness options. Because of its memory foam material and thicker height, testers said it was a bit more challenging to unroll onto their bed, but appreciated the corner straps to keep everything secure. The foam is perforated throughout to help dissipate heat and allow more airflow. With high marks for comfort and support, we recommend this pick for those who prefer a firmer feel.

While this pick is definitely an investment, testers rave that the comfort from Sleep Number products is "unmatched."

    How we chose the best cooling mattress pads and toppers
    linebreak

    Pros in the Good Housekeeping Institute Textiles Lab have sent over 30 mattress pads and toppers to ~100 consumer testers, leading to hundreds of data points to analyze before making these picks. Testers provided feedback on comfort, support, ease of set-up, feel and more. In addition to having testers try them out first hand, GH fiber scientists reviewed product claims and evaluated each pad or topper's construction. These picks are from top-performing brands with vetted cooling technologies or materials.

    What to look for when shopping for cooling mattress pads and toppers
    linebreak

    Many products claim to provide cooling benefits, but there are actually no set definitions of what "cooling" means. Therefore, brands can make these claims with nothing to back them up. GH textiles pros are here to help you shop for cooling bedding that will actually work. Here's what to look for:

    ✔️Cooling technologies: Phase change materials actually store and release heat to keep you at a stable body temperature. Threads are treated with phase change technologies to provide real cooling effects. Opt for well-vetted technologies like Outlast and 37.5.

    ✔️Perforated foam: Memory foam is known for holding onto heat. If you're looking for the supportive feel of memory foam without the risk of overheating, try foam that's perforated throughout. It'll allow increased airflow for a more breathable feel.

    ✔️Temperature regulating materials: Certain materials can help provide a cooler sleep like polyester and lyocell/Tencel, which wick away moisture. Wool also has great temperature regulating properties, making it a great pick for both warm and cold weather.
