How to choose the best cooling mattress

Choosing the right cooling mattress for you comes down to several different factors, including your sleep and comfort needs, budget, and the level of cooling you require.  Most of the beds in our cooling mattress guide rely on design, cutting edge cooling technology and natural materials to promote airflow and wick away any excess moisture. 

While some cooling mattresses rely on phase-changing materials or gel-infused foams, many of the beds in our best organic mattress guide do a good job of regulating temperatures, thanks to the naturally cooling properties of natural materials. 

The type of mattress can also affect how cool your mattress sleeps. Memory foam mattress can trap a bit of heat (but certainly not all), while hybrid mattresses tend to sleep cooler, thanks to the added airflow that the coils provide. Ultimately, the best cooling mattress for you will deliver on cooling, comfort and cost.
