The Comfort Light Range has a double-layer construction in the upper body area for maximum comfort and insulation and a single-layer construction in the head and foot area where less pressure is exerted on the mat.
Air Sprung Cells
Air Sprung Cells are the core technology of the Sea to Summit sleeping mat range. Instead of a typical partition wall construction, Sea to Summit sleeping mats are provided with a spot-welded construction of interconnected chambers that form a large-area matrix. These chambers are called "Air Sprung Cells". They function like pocket spring mattresses with each chamber deforming independently so that the mattress can adapt to the shape of the body. This construction makes the mats softer and more comfortable, provides a larger body contact area and balanced pressure distribution.
Extrusion TPU lamination
The TPU coating is applied in a special way that was previously used exclusively in the medical and aviation industry. In addition, an antimicrobial treatment was integrated into the TPU to prevent mould inside the mat.
A 40D ripstop nylon material has been developed for the surfaces of the mats, which offers the ideal mix of weight and durability. Light, white TPU is attached to the inside, making the material airtight and weldable. A thin PU film is applied to the outside to make the surface non-slip, to protect it against pinching and to make repairs with self-adhesive patches easier
Sea to Summit has also developed a lightweight, double-sided TPU-laminated 20D Nylon material that is weldable on both sides. This 20D nylon inner material is used inside the offset double-layer Air Sprung Cell construction
