Best Cooling Mattress

Your body generates heat all night. A mattress traps or dissipates that heat depending on its construction:

• Dense foam absorbs and retains body heat — memory foam is the worst offender because it's designed to contour closely, maximizing body contact
• Pocketed coils create air channels that allow heat to escape downward and sideways
• Cover materials affect the surface temperature you feel — some fabrics trap heat, others wick moisture
• Body sinking — the deeper you sink into the mattress, the more surface contact and the more heat trapped

Two main factors determine how hot a mattress sleeps: airflow through the core (coils vs foam) and surface cooling (cover material and upper foam layers).

Features that actually work:

• Pocketed coils — The single biggest cooling factor. Air circulates freely between individual coils. This is why hybrids consistently sleep cooler than all-foam.
• Gel-infused foam — Gel beads absorb and distribute body heat more effectively than standard foam. Noticeable but not transformative.
• Ventilated/perforated foam — Holes punched through foam layers create airflow channels. Effective when combined with a coil base.
• Phase-change material (PCM) covers — These fabrics actively absorb excess heat and release it as you cool down, maintaining a more constant surface temperature.
• Tencel and moisture-wicking covers — Draw sweat away from the body, preventing that clammy feeling.
• Latex — Naturally breathable with an open-cell structure. Sleeps cooler than memory foam, roughly equivalent to hybrid.

Features that are mostly marketing: "Cooling" labels on standard foam, copper-infused foam (minimal effect), and thin gel memory foam toppers over a hot core mattress.

If cooling is your priority, the comparison is clear:

Hybrid wins for cooling — coils provide passive airflow that continuously moves heat away from your body. Even without special cooling tech, a basic hybrid sleeps noticeably cooler than a basic memory foam mattress.

Memory foam can be cooled but requires premium features: gel infusion, ventilated layers, and cooling covers. Tempur-Pedic Breeze is specifically engineered to sleep up to 3° cooler than standard TEMPUR. The ActiveBreeze has an active temperature regulation layer. Both work — but add $1,000-2,000 to the price.

Bottom line: If you sleep hot and don't want to pay a premium for cooling tech, choose hybrid. If you want the pressure relief of foam and are willing to invest in cooling, Tempur-Pedic Breeze delivers. Full foam vs hybrid comparison →
