This chapter begins by contrasting the decorative of the traditional furniture with the functional form of the modern furniture, which allows "liberated" living. It then discusses the importance of space in the home, in which human movement is central. Furniture should not be obstacles, but the form should be adapted to the human scale. They should be grouped in such a way that they do not impede the traffic space in the home or interfere with spatial functioning. Nicolaï-Chaillet discusses the so-called switch furniture, which is easily expandable with a minimum use of space and takes up little space. Like the furniture, the number of utensils should not be too large. That only creates clutter. The interior should radiate space and tranquility, which also means that simple patterns and plain fabrics are preferred. Using numerous drawings with captions, she shows how the home should and should not be decorated. The chapter concludes with an ergonomic treatise on seating. In doing so, she gives examples of designs by A. Aalto, M. Stam, M. Breuer and G. Rietveld, among others. For review, see Alma-Heijnen,L., 'I can Wonen', in: Good Living 12 (1959) 4, p. 122-124.
