How do you remove the rear seat on a 1991 Honda civic std?

Hey there, I was having the same issue as you, if you look on the very left and right crevices while the seats are folded down you will see two black clips, pop those out with a flat head screwdriver, and you can get the back tops off, then for the back bottom there will be a bolt that the rear upper seats were hiding, take out that bolt and then lift the bottom back seat from the area closest to where the bolt used to be and then it should simply pull off.
