The primary feature of a dual comfort mattress is its ability to offer two distinct firmness levels. This means that one side of the mattress may be designed to feel firmer, while the other side may offer a softer feel. This allows you to flip the mattress over to switch between firm and soft surfaces, catering to different sleep preferences or changing needs over time.
