For Core77, Rain Noe investigated the attic steps design problem and the fact that nobody has really solved it yet:
I’ve got your standard pull-down unfolding attic steps, and they kind of suck. I mean the engineering is clever but the UX is poor.
Years ago we looked at this alternative Concertina Ladder design. It doesn’t seem to be much of an improvement, and that was back in 2009, so I just checked to see if any advances have been made.
