Short answer: A cooling cover layer designed to actively disperse heat through the night, paired with an airflow-oriented construction intended to avoid the heat-trapping feel of older closed-cell foams.
Why two separate features address the same underlying concern
The cooling cover and the breathable foam construction are two distinct components both targeting heat retention — a common complaint with traditional memory foam.
Why "older closed-cell foams" is a specific, comparative reference
This directly contrasts the pillow's construction against a named category of older foam technology, giving you something concrete to understand the improvement against.
💡 Worth knowing: per the official materials list, this is memory foam without latex — worth noting for anyone with a latex sensitivity.
