The innovative Delta Core system maximizes the comfort and thickness of our Self Inflating mattresses while minimizing weight and bulk. 40% of the initial volume of the PU foam is removed in horizontal Delta-shaped cores, giving minimal weight and packed size. Importantly, the top and bottom surface of the PU foam remain completely intact. This ensures consistent warmth along the full length of the mattress and significantly improves bonding of the foam to the shell fabric, which reduces the chance of delamination.
The shape and size of the Delta Cores are adjusted across the different thicknesses of our mattresses to ensure strength and durability combined with excellent support. The horizontal Delta Core technique is used in our Comfort Light SI, Comfort Plus SI, and Comfort Deluxe SI models.
