Telephone operators served as their own controls in two field studies of advanced furniture designed for video display terminal (VDT) workstations. The advanced furniture was characterized by dimensions that were easily adjusted by users, in contrast with conventional furniture that provided either no adjustments or inconvenient adjustments that could only be made with difficulty. An eight-week study focused on advanced VDT tables, and a fiveweek study focused on advanced chairs. Four combinations of advanced and conventional workstation components were compared. Although on-the-job discomfort was reduced when either conventional component was replaced with an advanced component, the effect was far greater when the advanced table and the advanced chair were used together. The adjustments of the advanced furniture were reported to be easy to use, and the advanced furniture was rated more highly than the conventional furniture.
