The Delta Core system maximizes the comfort and thickness of the mattress while reducing weight and bulk of the polyurethane foam core of our self-inflating mattresses. Our patent-pending coring process removes 40% of the initial volume of the PU foam, giving us a minimal packed weight and size.

This coring technique has the additional benefit of keeping the top and bottom surface of the PU completely intact. This ensures consistent warmth along the full length of the mattress, avoiding the vertical holes that have traditionally allowed warmth to leach downwards. The full foam surface also provides improved bonding of the foam to the shell fabrics of the mattress, thereby greatly reducing 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, while still giving the user excellent support and self-inflating performance.

We have literally put a new twist on our very successful multi-function valve so it specifically addresses the inherent characteristic of self-inflating mats - that is, the problem of the foam trying to re-inflate as you're packing up. We've engineered the "one-way" inflation valve to be reversed and used to prevent the mat from drawing air back in. This allows you to roll the mat up as small as possible without fighting re-inflation as you go. This patent-pending valve design has the same slim profile, faster inflation than traditional screw valves, easy pressure fine tuning, and super fast deflation rate as our air mattresses and pillows.
