Per CRNG:
How about sitting on the stairs and going down one at a time like you
see pre-walk children do? I'm serious. I had a leg injury once that
lasted a couple of months and that's what I was able to do.

Admittedly it's pretty embarrassing if you have guests over. And this
is obviously not a long term solution. Just something to get you by
(or down) until you figure out something permanent.

Actually, that was one of the first things that crossed my mind.

I even considered some sort of plank to slide on.

Short of an actual lift, it seems like the most logical and safe
approach because it already lowers one's body - with or without the
plank to slide on.

But I agree with the observations of everybody that the long term
solution involves a lift.
