My understanding is that VW had a "Weekender" option and for a 7 passenger van that was a fold down rear seat with a matching cushion over the engine cover.

now I'm  confused my 85 GL 7 passenger has a Z bed is that not a  factory
item?

some people call ANY dark colored cola "coke" regardless of who made  it
some people call ANY facial tissues "kleenex" regardless of who made  it

the name "z bed"  is a brand name, and it was a hardware kit to make  your
vans rear seat into a bed...made by a now-defunct company called Z Products
that was not affiliated with volkswagen.  they just made aftermarket
camping products for vw vans.
its NOT a volkswagen name.
somewhere along the line someone started INCORRECTLY calling ANY  rear bed
in volkswagen vans or campers a "z-bed' weather it was made by Z  Products
or not...and the name somehow INCORRECTLY stuck.

your 85 GL seven passenger van probably has the volkswagen factory "rear
bed option and folding middle seat option"     please do NOT  call it a Z
bed.
