Dimensional analysis of seating furniture from the 1960s and 1970s intended for redesign

Furniture is an object that accompanies us in everyday life. Therefore, it is important to choose appropriate dimensions, tailored to the human body, which will ensure comfort during use. In this study, the dimensions of seating furniture from the 1960s and 1970s were analyzed from an ergonomic perspective. The chosen period of furniture creation is not accidental, as it has been observed that furniture from this era is often renovated or redesigned. They are not only found in homes but also in public spaces such as cafes, schools, and cultural venues. Based on gathered literature, specific specimens were described and served as the basis for further research. Ten armchairs and twelve chairs were measured, and the obtained dimensions were analyzed. The results were compared with guidelines characterizing ergonomic seating. Additionally, percentile models for sitting positions were analyzed, leading to conclusions. After conducting research and analyzing the dimensions of chairs and armchairs from the 1960s and 1970s, it was found that the overall dimensions and important functional measurements for ergonomic seating deviate significantly from the applicable standards.
