Newcastle combines extra firm support with a more cushioned Eurotop surface, making it ideal for sleepers who want a solid, stable mattress without an overly hard first feel.

At its core is an extra firm pocket spring system designed to provide steady, even support throughout the night. Individually wrapped pocket springs respond independently to movement, helping to reduce partner disturbance when sharing the bed.

The plush Eurotop comfort layer adds cushioning at the surface while maintaining the supportive, extra firm feel underneath. A foam-encased perimeter strengthens the mattress edges and provides a more stable, usable sleeping surface from edge to edge.
