ABSTRACT
Health disorders suffered by elementary and junior high school children were first noticed in Japan in the early 1970s. Simultaneous evidence indicated that although Japanese school children are ill, they are also not healthy. Class and health teachers in Japan observed that poor postures were common in elementary and junior high school children. The objective of this research was to develop a simple method for allocating chairs in accordance with the child's stage of growth. The following problems were identified with school chairs: In 1986, an additional survey was conducted to investigate how teachers and children selected chair sizes. When asked why they selected the particular chair size, many subjects answered that their decision was based on personal preference and the fact that their teacher judged it suitable. Lower leg length, upper leg length, and body weight each affects chair selections. Body weight is closely related with selected seat depths.
