Interesting, well presented and well curated. 

The information in the book isn't just about the creation of the chair but the events in Rowlands life that led to the 40/4 and different versions of multiple designs (with different material types and the sketches) for several of his creations that modified it and went hand in hand with creating the 40/4. His background in different art styles and his education plays a part as well as many wonderful color photographs that make this more than a coffee table book.
