Ford Chateau Rear Fold Flat Bench/Sleeper
Not mine, but hate to have it go to waste. At the local Pick N Pull for those in the San Francisco Bay Area. It's in Richmond, CA. In the $50-60 range per their website.
Folds up and lays flat. Recline lever may need a spring. Not seriously stained and totally cleanable. Did not observe any notable rips and tears. Did not smell bad. Little wet from rain, but left upright to help it dry(er). As good as any seat you can find in a wrecking yard. Give it a good thorough cleaning and put it to use. Available as of 12/19 at 3pm.
