Almost everyone will feel that sleeping on the airplane is an extremely uncomfortable experience. The noise and the small seat make people feel nervous and unpleasant. The biggest problem is we have to sit and sleep. If people can lie down they would feel much comfortable.
I designed a smart garment for people to sleep on the airplane. With muscles being supported, people don't have to put one's strength on keeping their gesture. The garment can be controlled by several ways. Also involved digital fabric inside this garment.
