George Nelson platform bench (No. 4692) was made by the Herman Miller Furniture Company Inc. circa 1950s. It was designed primarily for high and low storage cases. But it was also used as a coffee table or as extra seating (with or without a cushion). This bench is made of an ebonized hardwood and retains it's original paint.
