Lightweight all-season comfort and performance.
Using our Delta Core™ technology, the Comfort Light S.I. is for those of us who are looking for the perfect compromise between comfort and weight in a traditional self-inflating foam mat.
Thicker, lighter self-inflating mattress with Delta Cores™.
At 5 cm thick, you can be sure of a great nights sleep while an R-value of 2.7 will give you plenty of insulation for 3-season comfort and still leave you with plenty of room in your pack for everything else.

Our Delta Core technique is a truly innovative approach to reducing the weight and bulk of the polyurethane (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.
Ever woken up cold because you slipped off your sleeping mat in the middle of the night? Not any more.
Anti-slip silicone print patterns to help your sleeping bag stick to your mat, and your mat to the tent floor.
We’ve engineered the “one-way” inflation valve to be reversible and used it 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 pillow.
Easily secure your Sea to Summit pillow to your Sea to Summit mat for a slip-free sleep.
Designed to keep your pillow exactly where its meant to be—on your sleeping mat—our unique PillowLock™ hook-and-loop fastener patches come standard with all our mats from mid-2019.
ASTM F3340-18 R-values
An R-value (Resistance-value) is a metric used to rate how effectively your sleeping mat resists heat loss. It’s the only way to know how well your mat will prevent your body heat being leeched away by ground temperatures (which can be a lot colder than air temperatures).
This value can be tested in-house but at Sea to Summit our mats are independently tested at a laboratory to precisely controlled standards.
The new industry standard ASTM F3340-18 testing has now been introduced and all Sea to Summit mats released from 2020 onwards are tested to this standard.
