San Francisco-based startup Zephyr Aerospace has debuted a design for what it calls “the world’s first lie-flat double-decker seating concept,” which is designed to let people sleep while maintaining distance, Fox News reports.

“The idea, still in the concept phase, could revolutionize the in-flight experience as airlines encourage people to travel again,” reads a press release for the concept.

According to Zephyr, these double-decker seats can be installed on existing wide-body aircraft in a 2-4-2 seating configuration. And by stacking the seating on top of each other, the company claims that airlines would still be able to fit the same density of passengers in their premium economy cabins.
