It indicates the foam has been tested for content (free of certain substances like ozone-depleting chemicals, formaldehyde, and certain phthalates), emissions, and durability. The cool gel memory foam top layer in this mattress is CertiPUR-US certified.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs cool gel memory foam better for hot sleepers?\u003c\/strong\u003e\u003cbr\u003e\nCool gel infused memory foam is designed to dissipate heat more effectively than standard memory foam. The Mona Series uses cool gel as its top layer, paired with an air-mesh fabric cover that allows airflow. Real-world cooling depends on bedding choice, room temperature, and personal sleep environment.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat does the egg-shaped foam middle layer do?\u003c\/strong\u003e\u003cbr\u003e\nThe egg-crate profile of the middle foam layer increases surface area for airflow and helps distribute pressure across the mattress. It sits between the cool gel top layer and the high-density support base, contributing to the medium-firm feel.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill this fit a dust mite mattress encasement?\u003c\/strong\u003e\u003cbr\u003e\nThis mattress is 21cm deep, 137 × 188cm (Double).
