40D nylon construction with rip-stop weave, antibacterial coating

The inner layer utilizes embossed thermoplastic polyurethane (TPU), renowned for its flexibility and high resistance to damage, and is further protected by an antibacterial coating designed to inhibit the development of fungi and mold within the air chambers. For the exterior, lightweight 40D nylon is employed, strengthened by a Rip-Stop weave to safeguard against tearing. A supplementary polyurethane finish grants the surface anti-slip characteristics and enables swift, localized repairs with adhesive patches.

Air Sprung Cells and PillowLock System

The mattress features an advanced system of 181 interconnected Air Sprung Cells, ensuring optimal weight distribution and tailored contouring to the sleeper’s body. This design greatly improves overall sleeping comfort by minimizing pressure points and providing enhanced stability throughout rest. The adaptive structure of the cells promotes superior support, allowing for a restful experience. Incorporation of the PillowLock system secures the pillow in place, effectively preventing unwanted movement during sleep and maximizing comfort for the user.

Easy inflation and compact dimensions

Featuring a wide, one-way valve, the mattress enables rapid inflation and allows for precise adjustment of firmness by adding or releasing air as needed. The valve's design ensures no unintentional air escape. For complete deflation, simply open the valve.

When compressed, the mattress packs down to a compact size of 17 x 7.5 cm, making it convenient to store in a backpack.
