KLM Royal Dutch Airlines has introduced its new world business class interior, featuring new full-flat seats, carpeting, panel decorations, curtains, lighting, blankets, cushions and upholstery.

KLM said the full-flat Diamond Seat, manufactured by BE Aerospace, is positioned to ensure greater privacy. The number of seats in world business class will be reduced from 42 to 35 aboard 22 Boeing 747-400s.

The new carpet is made partly of discarded KLM ladies’ uniforms. The airline said it recycles all of its carpets in collaboration with carpet manufacturer Desso.

The new design will be inaugurated in July, and the entire 747-400 fleet should see interior redesign completion by April 2014.
