Layer Details
Memory foam comfort layer
A layer of body-moulding memory foam sits on top of the springs and moulds to your body. It softens the surface of a firm mattress, so you feel cushioned rather than resting on hard springs.
Miracoil spring core
A continuous head-to-toe Miracoil spring system with three support zones forms the base. The zoning gives different parts of your body the support they need, and the continuous coil design carries that support out towards the edges.
