KLM has finally revealed the final look of its fully-flat seats to be fitted in its long-haul business class flights. Unveiled at Amsterdam Schiphol airport in an aircraft hanger the airline has chosen to use customized version of BEAerospace's Diamond seats, which are very similar to the one used by United Airlines in its BusinessFirst class.

KLM has decided to first convert its Boeing 747-400s with these new seats. The airline plans to redesign all of their 22 Boeing's with these Fully-flat business class seats by the end of April 2014. With this introduction the business class cabins will have 35 seats, which is seven less than the present seat capacity.

Work on the first Boeing 747-400 will begin in June 2013, and it if all goes well then KLM plans to launch its inaugural flight done with all the new interiors in July 2013. After all the 22 Boeing 747-400s are fitted with these new seats, the airline plans to retrofit all its Boeing 777-200s.
