In 1967, Harcourt designed a series of swivel armchairs with trumpet bases, based on a shell shaped template. The shell is large enough to curl up in and is the paragon of his philosophy that “the chair should focus on the person, and not the other way around.” To begin with, there are different versions of the chair for men and women (with high and low backs respectively). These were later followed by models with stitched edging, fixed cushions and deep-buttoned padding.
