The Amerisleep AS3 is a 12-inch hybrid mattress that pairs plant-based Bio-Pur memory foam with a pocketed-coil base for a medium feel. Its HIVE five-zone layer adds targeted support and airflow, and the Refresh Cover is claimed to sleep about 7 degrees cooler than a standard polyester cover. It is fiberglass-free and aimed at side and combination sleepers who want pressure relief without a sinking feel. Against rivals, it sits in the same hybrid class as Leesa and Casper models but leans harder on cooling and zoned support.
