The Silentnight Hatfield Memory mattress features the unique Miracoil spring system which offers twice as many springs as an ordinary system to offer improved head to toe zoned support and pressure relief. A layer of body moulding memory foam allows free movement throughout the night with quick recovery to support your body and provide a soft cocooning comfort for blissful sleep. This mattress provides a medium firm comfort, meaning it’s great for those who change sleeper position as they sleep – or who’s partner sleeps differently to them. The Miracoil spring system in this mattress provides no roll together for less partner disturbance, and zoned support scientifically proven to provide superior spinal alignment and improve posture. While the memory foam responds to your body temperature to offer pressure relief where you need it most. This mattress is finished in a soft knit cover for a smooth sleeping surface and added comfort. This mattress is hypoallergenic, for healthier sleep.
