Assessment of the match of Anthropometric Dimension with Classroom chairs and Determination of the Standard Classroom chairs Dimensions in Students of 3th and 6th grades primary schools in Kerman
Abstract
Background and aims: Sitting on an unfitted chair can cause disorders of musculoskeletal system. In this study we investigated to determine the match of anthropometric dimension with classroom chairs in the students of 3ed and 6th grades primary school and finally offer the best dimension of the classroom chairs. Methods: 572 primary schools students (male and female) were attended in this study which 275 and 297 of them were in 3ed and 6th grade respectively. Some of anthropometric dimensions such as shoulder height, elbow height, popliteal height, popliteal - buttock length and buttock breath were measured. Then anthropometric dimensions were compared with seats dimensions and the appropriate seat dimensions were offered. Results: results showed all of the seat dimensions were larger than the anthropometric dimensions in the 3ed students. Also in the 6th grade students only seat height were match with popliteal height 85.3 and 84.5% in the girls and boys student respectively. Back rest height and seat depth were the larger while armrest height and seat width were the smaller than the students physical dimensions. Conclusion: According to the differences in the body dimensions of the third and sixth grade students there are a little difference in the size of their seats. All of the seat dimensions are larger than the anthropometric dimensions in the 3ed students. By reducing of the seat’s size, in addition to the decreasing in the production fee, we can increase match between students’ anthropometric dimensions and seats’ dimensions.
