Mismatch Analysis of Elementary School Furniture in Several Regions of Central Java, Indonesia, and Redesign Recommendations

Abstract

The aim of this article was to determine the mismatch between the existing desks and chairs in elementary schools and the anthropometric measurements of students in several regions of Central Java, Indonesia. Based on the mismatch, recommendations are given to improve the fit of the desks and chairs with the students’ anthropometry. Five critical dimensions of desk and chair were included in the analysis: seat height (SH), seat depth (SD), seat width (SW), desk height (DH), and under-desk clearance (DC). The analysis provided three critical chair dimensions and two critical desk dimensions with a high degree of mismatch. ANOVA and Tukey tests were performed to determine the grouping of students’ anthropometric data. Four sizes of chair and three sizes of desk are proposed based on the results of the analysis. The proposed dimensions lower mismatch more than the existing dimensions.
