Rogers 1855 is a premium mattress collection designed to promote airflow, regulate moisture, and maintain a temperature-neutral sleep environment. Rather than relying on cooling gels or chemical treatments, Rogers 1855 uses only breathable materials such as wool, linen, cotton, natural fibers, and individually wrapped coils to help hot sleepers remain comfortable throughout the night. The Rogers 1855 line began with a different premise: foam traps heat. So there is no foam.
