Interior Cabin Seats For Lilium Jet Reveal With the Lilium Jet eVTOL coming closer to reality and entering service, the interior aspects of the craft are becoming more zeroed-in. For example, Lilium recently partnered with Expliseat (a French seat manufacturer) to create the cabin seats of the Lilium Jet. The seats will be plush and luxurious looking but more importantly will be lighter than average aluminum seats. Expliseat makes their seats using high-grade materials like carbon fiber and titanium. This will result in a 35% lighter product per seat.
