United States, 1960s
Florence Knoll's parallel bar lounge chair, model 51, places an armless angled seat upon a squared-off steel frame with a brushed chrome and black finish. The tufted back and seat of this pair have been newly reupholstered in Knoll's Ferry bouclé in Marin (a charcoal grey with other underlying hues). The seat slopes from 14 inches at the back to 16 inches at the front.
