Technical Features
What is 30D Soft Touch Stretch Polyester TPU?
The 30D Soft Touch Stretch Polyester TPU is a knitted fabric with a TPU lamination and is used in our Self Inflating mats. The advantage of the polyester knit is a soft handfeel and the stretchy feel of the mat surface. The TPU lamination makes the fabric airtight and allows the PU foam inside our self inflating mats to be bonded to it.
What is Delta Core Technology?
Sea To Summit Delta Core technique is a truly innovative approach to reducing the weight and bulk of the polyerthane (PU) foam core of our Self-Inflating mattresses. Our patent pending coring process removes up to 40% of the initial volume of the PU foam, retaining enough for optimal support and comfort, while minimising the packed weight and size of the final mattress. Importantly, this coring technique has the additional benefit of keeping the top and bottom surface of the PU foam 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 Coring technique is used in our Comfort Light SI, Comfort Plus SI and Comfort Deluxe SI models.
