Sea to Summit Comfort Plus Self Inflating Regular Sleep Mat Red

Delta Core-V technology

STS Delta Core technique is a truly innovative approach to reducing the weight and bulk of the polyurethane (PU) foam core of their Self-Inflating mattresses. Their 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. 

A multi-function valve specifically designed for self-inflating mats

STS have literally put a new twist on the 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. STS have engineered the “one-way” inflation valve to be reversible 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 STS air mattresses and pillows.
