Memory foam (visco) pillows contour under pressure, improving pressure distribution by cradling the head and neck. Some users, however, experience more heat retention and sweating. Latex pillows are more elastic, rebound faster, and often provide better airflow with a bouncier support feel. The goal for neck health is not softness—it is stable support that maintains neutral alignment. Hot sleepers and those prioritizing breathability may prefer latex. Those who want deeper contouring and pressure relief may prefer memory foam. The best choice depends on sleep position, heat/sweating tendency, allergy sensitivity, and support needs.
