When warmth builds up, the microcapsules release as much cooling as the sleeper needs, then they rest again. Meanwhile Cool regulates moisture on the sleeping surface and protects the mattress. Its fine fabric leads moisture away, so the surface stays dry. Over the years the topper keeps its form, and the filling keeps its function. Moreover the cooling effect lasts permanently. Even with daily use it remains dependable, because the fabric is robust.
