How to fold down 60/40 bucket seat from 90s GMC Sierra

[Gregski]

hey guys, a bit of an off question I bought two of these 40% low back bench seats from two different trucks at the local Pick N Pull and want to store them on a garage shelf for now, and one of them folded down (forward) perfectly flat (makes for easy storage) the other one refuses

now I know you pull the backs up ever so slightly and they lean forward allowing you to get to the extended part of the cab, but one folded down completely so now I am doubting myself thinking is that one just broken or do they actually do that, cause for the life of me I can't get the second one to lay down flat, I'm like 4 beers into it trying, ha ha
