Purple's grid technology — originally developed for military and medical applications — extends into their pillow lineup as the Harmony (full grid structure) and Cloud (grid panels). The Harmony is the most technically distinct pillow on the market for hot sleepers who don't want a foam feel.
Purple's HyperElastic Grid creates air channels that keep this pillow dramatically cooler than any foam option.
More traditional pillow feel than the Harmony — soft down-alternative fill with Purple grid side panels for airflow.
