I can’t imagine that with stacked seating and ladders that come out and block the aisle that you could evacuate a plane in 90 seconds or less. That’s the standard for the FAA: https://www.washingtonpost.com/local/trafficandcommuting/first-of-their-kind-tests-are-aimed-at-setting-new-standards-for-airplane-seats/2019/11/28/55bcdd3a-0ae4-11ea-97ac-a7ccc8dd1ebc_story.html https://www.washingtonpost.com/local/trafficandcommuting/fir...

Another safety issue seems to be that people would always have to wear a seatbelt in the upper row, otherwise unexpected turbulence could lead to falls and bad injuries.

  Turbulence that bad would be the kind that causes injuries in normal seats too (by banging heads in the celing for example). Its more common and dangerous than people think and that's why we are instructed to always wear the seatbelt when seated. Cabin staff couldn't really give more than that advice to people in top seats, but perhaps people would believe that warning in this case because they can see the danger.

It's not meant to fill the whole plane, just a few premium economy rows.

If you look at a modern long haul cabin like a BA 777 [1] or the new SAS A350 [2], you'll se that the number of "economy plus" seats is quite small. It's 3 rows (18 seats) on the BA plane, and 4 rows (24 seats) on the SAS plane. It's well under 10% so even the evacuation time for the whole plane isn't going to be severely affected by the seat change in maybe 10% or 20% of the seats. There would be no emergency exit windows in this section, for example. It would be say 30 people of which half(?) would be on the upper level. So say 15 people out of 280 on a full A350. It's not nothing, but the speed of disembark in reality will be more dependent on the age of the people in economy than on whether 15 people will need to climb down from the top shelf. Obviously the idea behind making economy plus more attractive like this is to be able to sell more of it and charge more for it, so it may be that airlines want to install this on maybe 25% of a cabin, at which point it might start affecting evacuation etc. But if it's a simple swap in current economy-plus sections it wouldn't be a big issue because of how few seats that is.

The article is so annoying, I searched for the word "security" and this word came up zero times. I wonder if the fancy San Francisco "industrial designer" even considered that?
