High Quality Content by WIKIPEDIA articles! The Action Office is a series of furniture designed by Robert Propst, and sold by Herman Miller. First introduced in 1964 as the Action Office I product line, then superseded by the Action Office II series, it is an influential design in the history of “contract furniture” (office furniture). The Action Office II series introduced the concept of the flexible, semi-enclosed workspaces, now better known as the cubicle. All cubicle office designs can be traced back to Herman Miller’s Action Office product lines.
