How We Score Cooling
Our cooling score rates each mattress on a 1-10 scale based on four factors: material thermal conductivity, airflow design, cover breathability, and sustained cooling over a full 8-hour sleep period. We weight sustained performance most heavily because many mattresses feel cool initially but trap heat after 2-3 hours.
Material Conductivity
How effectively the foam or gel conducts heat away from the body. Copper and graphite rate highest.
Airflow Design
Whether the construction allows air circulation. Pocketed coils create passive ventilation that solid foam cannot.
Cover Breathability
The cover material matters. PCM covers actively absorb heat. Tencel wicks moisture. Polyester traps both.
Sustained Performance
Does it still feel cool at 3am? Many gel foams feel cool initially but warm up. Hybrid designs maintain cooling longer.

Full review →Cooling Technology Overview
Modern cooling mattresses use five main approaches to manage body heat. The best models combine multiple technologies for sustained cooling through the night. Understanding what each technology does helps you cut through the marketing.
Gel-infused foam
Absorbs heat initially but can saturate. Better than plain foam, weaker than coils or PCM.
Copper-infused foam
Conducts heat laterally away from the body. More effective than gel for sustained cooling.
Graphite-infused foam
Creates thermal pathways through the foam. Similar effectiveness to copper at a lower cost.
Phase-change material (PCM)
Actively absorbs heat at a specific temperature. The most effective single technology for cooling covers.
Pocketed coil airflow
Passive ventilation through the mattress core. Essential for sustained overnight cooling.

Frequently Asked Questions
What is the best cooling mattress in 2026?▾
The Brooklyn Bedding Aurora Luxe is the best overall cooling mattress in 2026, combining CopperGel foam with a TitanCool cover and pocketed coil airflow. For active cooling, the Eight Sleep Pod 4 offers unmatched temperature control with its water-based system. For value, the WinkBed delivers strong cooling at a lower price point.
Are gel foam mattresses actually cooler?▾
Gel-infused foam sleeps cooler than standard memory foam, but the effect is limited. Gel absorbs heat initially but can saturate after a few hours. For sustained cooling, hybrid mattresses with pocketed coil airflow outperform gel foam. The most effective approach combines gel or copper foam with a coil layer and a phase-change material cover.
Is a hybrid mattress cooler than an all-foam mattress?▾
Yes. Hybrid mattresses use a pocketed coil support layer that allows air to circulate through the mattress core. This passive ventilation prevents heat from accumulating the way it does in solid foam. Every mattress in our top picks is a hybrid for this reason. If you sleep hot, avoid all-foam mattresses regardless of their cooling marketing claims.
Do cooling mattresses help with night sweats?▾
A cooling mattress can reduce night sweats caused by sleeping too hot. However, night sweats caused by medical conditions (menopause, thyroid issues, medications) require medical attention. If you only sweat in bed and not during the day, a cooling mattress with PCM technology like the Casper Snow or an active system like the Eight Sleep Pod is likely to help.
How much should I spend on a cooling mattress?▾
Effective cooling mattresses range from $800 to $2,500 for a queen size. Under $1,000, you can find budget hybrids with basic gel foam cooling. The $1,200 to $1,800 range offers the best balance of cooling technology and value. Above $2,000, you enter premium territory with advanced PCM and active cooling. A $200-$400 cooling topper is worth considering if your current mattress is still supportive.
What is phase-change material in a mattress?▾
Phase-change material (PCM) is a substance that absorbs heat as it transitions from solid to liquid at a specific temperature, typically 77 to 82 degrees Fahrenheit. In mattresses, PCM is embedded in the cover fabric. When your body temperature rises above the transition point, the material actively absorbs heat, creating a noticeably cooler surface. The Casper Snow uses HeatDelete bands with PCM technology.
