This bench is the first example of this model ever constructed. The model became one of his most popular designs in the 1950s and 60s. Later editions were subtituted with leather instead of laced cords and cross stretchers were also added.
cf. J. Adamson, The Furniture of Sam Maloof, New York, 2001, fig. 46, p. 47 for an example of this model with leather lacing.
