The film is based on the stage play of the same title[1] by Gerald Sanford, adapted by Matt Cimber, who also directed (credited on-screen as "Matteo Ottaviano").

[citation needed] The film also features an introduction by Walter Winchell who was a close friend of Mansfield's.

Pop then begins to tell Maria the story of Johnnie, a young woman who used to live in the building with her husband Frankie about ten years earlier.

As Pop finishes narrating the story to Maria, Flo comes into the kitchen; she is pregnant with Charley's baby.

While she removes her makeup and undresses, Billy professes his desire to marry her, stating that he does not care about her past.

She interjects by informing him of the many men she has been with and the things she has done with them, before then reflecting of a time when she was in love with a man whom she planned to marry.

The feature was shot in 1966,[citation needed] while Mansfield was married to her third (and final) husband, Matt Cimber.

[citation needed] The feature was released "legally" and "officially" in 1968; which was nearly a year after Mansfield's death in a car crash at the age of 34.

Her legally[clarification needed] final film appearance was in 1967's A Guide for the Married Man playing an uncredited cameo role.

Today Single Room Furnished is considered by Jayne Mansfield fans as one of her finest acting performances;[citation needed] some of her other dramatic performances were in Illegal, The Burglar, The Wayward Bus, all three Hollywood productions; and, two independent foreign films: Too Hot to Handle and The Challenge.
