Delta Core-V technology removes up to 20% of the weight and bulk of the polyurethane (PU) foam of a self-inflating mattress, while maintaining comfort and insulation.

Our unique approach uses sophisticated pressure-mapping data to create the blueprint for our distinctive graduated core pattern. Where extra warmth and support is needed for the body contact areas-shoulders, hips and feet-the core holes are smaller. In the less critical areas, we have removed more foam to minimise the weight and packed size. Delta Core-V technology is used in our Ultralight SI and Camp mat SI models.
