Its single-chamber design, not a separate upper and lower chamber, combines the comfort and lightness of Air Sprung Cell mattresses. Air Sprung Cell mattresses are made of numerous interconnected cells (air chambers) that are bonded together in a concave and convex shape. When inflated, they become elastic, allowing each cell to support your body weight and provide a comfortable sleeping experience. The uniquely developed multi-function valve combines a check valve for inflation, a release valve, and a button for fine-tuning firmness into a single, thin and compact valve. The included stuff sack for storage features a convenient built-in Airstream pump sack. The Airstream pump inflates with just one puff, allowing for quick setup.
