Ces sièges verticaux sont la dernière innovation pour augmenter la capacité sur les avions de 20%

Horse-saddle-style seating may be the latest design to increase capacity on planes, if one company’s designs get approved for use. Italian seating company Aviointeriors unveiled the new version of its Skyrider seat, Skyrider 2.0, at this year’s Aircraft Interiors Expo in Hamburg.
