The focus of this book is on functional seating, and the key argument presented is that functional seating needs to assist the person using it for the performance of seated tasks, enhance rather than detract from the person's posture and health, and it needs to provide aesthetic features that do not limit task or health. The book spans the period 3000BC to 2000AD and presents largely Western seating. This book is unique in its approach to seating because it draws together evidence that relates to seating that facilitates health and task while also addressing aesthetic factors. This evidence creates an understanding of how seats may be designed to not only promote bodily health but also allow functional optimisation of sitting and seating. This book is important to furniture and industrial designers, interior decorators, architects, those teaching seat design, health professionals attending and educating those who relax or work in the seated position, furniture historians, and members of the general public interested in the history of seating.
