The Nappak is designed to use in the office for the minimal space; quickly open and store; mobile and easily use. This Nappak sleep bag can be stored in a slim and round trolley, it features can be expanded in a a few minutes, quickly open and stow. Its inside translucent white color creates a relaxing atmosphere, and outside orange color give the people attention. I love this design, because its independent space can be separated from the offcie, give users more relax.
