Delta Core™
Technical Features

Delta Core™

The Delta Core system maximizes the comfort and thickness of the mattress while minimizing weight and bulk. This is a truly innovative approach to 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.

Importantly, 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 or frame-like gaps that have traditionally allowed warmth to leach downwards. The full foam surface also provides significantly improved bonding of the foam to the shell fabrics of the mattress, thereby greatly reducing 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, while still giving the user excellent support and self-inflating performance. The horizontal Delta Core™ technique is used in or Comfort Light SI, Comfort Plus SI, and Comfort Deluxe SI models.
