Experience instant cooling comfort with this Silentnight mattress. A hyper-conductive knitted sleep surface draws heat away from your body to help you fall asleep faster, while the UltraGel® comfort layer provides responsive pressure relief and is up to five times more breathable than standard memory foam. A dual layer of 2,000 Mirapocket® springs works alongside 1,000 individually pocketed mini springs to distribute weight evenly across the surface. The sumptuous boxtop features a micro-quilted lid, while a breathable mesh border promotes enhanced airflow.
