American Bedding 10-inch Medium Pillowtop Innerspring King Mattress pairs a plush pillowtop with a responsive innerspring core to deliver balanced, comfort-forward support. A memory foam layer contours to the body while polyurethane foam layers provide cushioned support, and the innerspring design promotes airflow to help regulate temperature. The cooling cover adds breathability, and the mattress is made in the USA. It works with a box spring or platform foundation to provide consistent support night after night for a wide range of sleepers.
