The new “saddle” seat, to be unveiled at a conference this week, increases the number of seats an airline can have in its economy class.
The seats would also offer storage space including a shelf for carry-on bags and hooks to hang a jacket or a handbag.
The makers say the seat would allow budget airlines, such as Ryanair, to cram more passengers into their tight cabins.
The seat, designed by Italian design firm Aviointeriors Group, based in Latina, in the country's south-west, is to be unveiled this week at the Aircraft Interiors Expo Americas conference in Long Beach, California.
