I can almost guarantee I've seen one of these at an estate sale and had no idea what it was!

There are so many things that could go wrong with this set-up.

1960 Cot for Babies & Toddlers

Pint-Sized Cot Keeps Baby Happy
From November 1960 Popular Mechanics


Built to provide baby with a safe, comfortable and familiar bunk anywhere the family goes, the new British "Autocot" fits snugly between the front seat and the rear deck in any car; won't slip during turns or sudden stops.  The canvas hammock is slung from an aluminum frame which expands from 40 to 48 inches in two-inch steps to adjust to cars of any length.  Outside the car, aluminum legs fold down to make a bed or seat for the yard, beach, or hotel rooms.  The whole cot weighs only four pounds, and collapses for carrying and storage into a flat 24-inch package.  Thus a bed familiar to the baby can be carried anywhere.
