To provide a touch of softness to the overall hardness, the Comfort Mattress blends ultra strong foundations with thin comfort layers. The mattress may also include breathable components that prevent heat build-up and enable users to sleep cool, as well as a well-reinforced perimeter that doesn't sink too much when users get in and out of bed. A support core with large pocketed coils and a layer of high-density foundation foam are also included in the mattress. These materials assist to keep the sleep surface level and strengthen the border to avoid sinkage along the borders.
