I read somewhere the updated Royal Laurel Class business class seats have been styled by ... “We wanted EVA's business class experience to be fresh and ... all work together,” said Johannes Lampela, Design Director at BMW Designworks' LA Studio.
This has been mentioned throughout the press releases and in the discussion from the outlook thread extensively. The "BMW designed" seat carries quite a bit of weight with the local Taiwanese market, who relate the "BMW" to ultimate luxury.
