The 10 Best Cooling Mattresses for Hot Sleepers (2026)

Nothing ruins a great night of sleep faster than getting too hot. We slept on a myriad of cooling mattresses to find which ones drew the heat away best.

The top 3

  1. Phase-Change Materials (PCMs) Explained: Phase-change materials absorb and release thermal energy to regulate body temperature, often infused into foam or fabric, proving most effective during the initial sleep-onset phase by buffering temperature fluctuations.
  2. Gel-Infused Memory Foam Innovations: Gel-infused memory foam helps wick body heat away, offering initial cooling, with its effectiveness significantly boosted when combined with an open-cell structure that allows for better heat conduction and dispersion.
  3. Hybrid and Open-Cell Designs for Airflow: Open-cell foam features interconnected air channels that allow air to circulate and release trapped heat, while hybrid mattresses combine foam layers with coils, creating ample space for superior airflow and heat dissipation.
