Help me identify this bench seat

[Ballo]

Hello. My friend has this bench seat and we can't fathom where it originated. It's aquamarine, wide (64 inches), and really uncomfortable due to a long seat and short backrest which is too far back. It has seatbelts and can fold flat like a futon.

Any ideas where this came from? Thanks

sounds like my 63 Nash/AMC rambler, but with belts it would have to be 68+..

best pic i could find.. back of the wagon was bench that folded down flat, and front seats folded down and connected to front of rears and made a queen size for camping..

oh, and Ballo, i forgot; welcome to Automotive Forums..
i hope others actually know for sure what you have..
with the little dots (rather than lined pleats), makes me think
more of the big three: GM, ford, chrysler; not my AMC..
