Sienna naugahyde, beige painted armshell, black wire base
From a 1954 Herman Miller poster, "A tailored foam rubber pad is fitted over the molded plastic shell in these new designs by Charles Eames. The upholstered pad is a single unit which may be removed for easy cleaning. These chairs are comfortable, lightweight, colorful seating solutions for home, office or commercial installations."
"Upholstered foam rubber pad adds resilience to basic molded plastic shell."
