How to Find the Best Mattress for Cool Sleeping: A Buyer’s Guide

In this guide, we’ve listed some of the most important factors you need to consider while shopping for a cooling mattress. 

Mattress cooling technologies

If you’re a hot sleeper, you’ll probably want to know which cooling technologies are on the table for you. 

Some of these include:

  • Pocket springs known to boost breathability

  • Gel-infused foam, designed to absorb heat

  • Phase-change materials, one of the newer technologies, it can significantly lower the temperature of your bed

  • Open-cell foam provides solid airflow and temperature regulation.

Typically, hybrid, latex and pocket spring mattresses are recommended for hot sleepers, while memory foam beds tend to sleeper hotter than others. Still, thanks to these cooling technologies, even foam mattresses can reduce the temperature at night. 

Trial Period

Most beds nowadays are ordered online, so sleepers do not have the chance to see the bed before purchasing it. Thankfully, most mattress manufacturers offer free trials, ranging from two weeks to a year, depending on the brand.

Warranty

It’s in your best interest to read the warranty policy before purchasing. Some companies offer a lifetime guarantee, while others limit them to 10 years. That said, look into what types of damage or defects are covered by the warranty to prevent any misunderstandings.

Price

Mattresses that keep you cool are available at all pricing points, depending on the materials used in the construction. Although there are affordable, high-quality mattresses available, longer-lasting mattresses tend to cost more.

Accessories That Can Help Hot Sleepers 

If you can’t afford to splurge on a new bed right now, there are more affordable alternatives to make your existing mattress cooler. 

Mattress protector

The best mattress protectors will not only cool you down but also protect your bed from stains, damage or spills. 

You can find mattress protectors featuring all kinds of materials, even special cooling blends originally developed by NASA for temperature regulation. Latex or gel-infused memory foam protectors are also a suitable solution for those who seek pressure relief with additional cooling benefits.

Mattress topper

A cold mattress topper is usually made of naturally breathable wool and phase change materials and is 1–4 inches thick. 

Mattress toppers are an excellent, cheap alternative if you don’t want to buy a whole new mattress. But if you want to cool down, opt for a topper that uses gel-infused memory foam or latex.
