For Sea to Summit, comfort is the most important attribute for a sleeping mattress. Sleeping well is paramount and is the best way to start the day. Sea to Summit is concerned with creating products that are lightweight, durable and as compact as possible while remaining as comfortable as possible. The new line of self-inflating sleeping mattresses joins the award-winning air mattresses by offering an even more comfortable sleeping experience. The range of sleeping mattresses is growing and now offers a sleeping solution for everyone.

Delcore :

Delta Coring technology is a truly innovative approach to reducing the thickness and weight of the self-inflating mattress while maintaining comfort. Design and manufacturing techniques optimize this process by removing 40% of the initial volume of the foam to reduce its size and weight. Solidity and durability guaranteed. This technology leaves the internal and external parts of the foam completely intact. Assured warmth distributed throughout the length of the mattress. This makes the foam stronger and more durable. Delta Coring technology is found in our Comfort Ligth, Comfort Plus and Comfort Deluxe models.
