The Sterling mattress by Sealy offers the firmest feel in the Enhance collection, without compromising on that all-important comfort. Pocket springs offer a gentle level of support and work independently to respond to your body shape and create a personalised feel. The springs are sewn together in their own pockets to reduce movement and provide a refreshing nights sleep. Combined with our deepest layer of Geltex, which offers pressure relief to the areas of your body that need it most. Geltex is reactive to both shape and movement and offers breathability in abundance, allowing air to circulate through the mattress easily and regulating your temperature as you sleep.
