I’m impressed they fit it in the standard pitch. One of the problems I had in trying to design a diagonal stagger like this was the squeeze between the outside corner of the window (most forward) seat and the rear inside corner of the seat in front — this will be narrower, and I wondered if you could get approval for how it might interfere with emergency exit. (After all, they are paranoid about how a reclined seat will interfere with getting out in an emergency.)

This approach misses one thing though. For those of us in the “widebody” category, and actually for everybody, you want room to spread your elbows. Part of my goal in getting away from the 3-in-a-row design was that it aligns us up so widest part of the body bumps into widest part. I would modify these seats so that there is a small hole at elbow level instead of a solid surface. This intrudes into the seat pocket area of the seat behind, but I would rather have somebody’s elbow taking my space there than somebody’s elbow/arm right at my elbow the way we do it now.

The padded lean-against curve is a nice touch I did not consider (as I switched to the alternating direction approach.)
