Castro Convertible sofa-beds
(perhaps known only to those of us who grew up in the NYC area)

Who's the first to conquer space?
It's incontrovertible
that the first to conquer living space
is the Castro Convertible.
It saves you space with fine design
and saves you money all the time.
Who's tops in the convertible line?
Castro Convertible!
