“…It seems logical that the furniture allocation system is not guided by chronological age, requiring several seat and desk sizes per academic year. This has been recognised on numerous occasions by the scientific community, and we agree with the collected data [ 12 , 14 , 23 , 24 , 25 ], along with the use of adjustable furniture [ 22 , 43 , 44 , 45 , 46 , 47 ].…”

Background: Back pain is common in secondary school students. If we adjust the school furniture to the anthropometric characteristics of the pupils, we will improve their posture and reduce back pain. There is a high degree of mismatch between the furniture used by students and that which should be used. The objectives of this research are to discover the degree of mismatch and validate two instruments that allow a correct allocation of the furniture. Methods: The selected sample was 132 secondary students (14.08 ± 1.10 years). An anthropometer was used to determine the ideal height of the chair and table; data were taken from body segments. The recorded values were compared with those obtained by the two measurement instruments to be validated. Inter-measurer and intra-measurer reliability and validation were performed using t-tests and Pearson’s coefficient, respectively. Different analysis techniques were used: descriptive, one-way ANOVA, t-test, and effect size. The established level of significance was ρ < 0.05. Results: The mismatch between the anthropometric dimensions of the students and the existing furniture in the classrooms was 98.5 % for the chairs and 100 % for the tables. The correlational analysis of the instruments to be validated shows an r = 0.993 in the chair and r = 0.996 in the table. Conclusions: There is a high degree of mismatch between the furniture and the anthropometric characteristics of the students. The proposed furniture allocation instruments are adequate.

“…Another mechanism is the “Peter lower leg meter” [ 28 ], which measures the popliteal height. This method is recommended by other authors [ 29 , 46 ]; it is unknown whether or not it follows a validation system.…”

“…Researchers have conducted many researches for designing ergonomically fit classroom furniture [9,17,[26][27][28][29][30][31][32][33]. Furthermore, there are some established standards regarding school furniture design in different countries, such as Japan [34], Chile [35], Colombia [36], United Kingdom [37], and the European Union [38].…”

Students spend a large portion of their time in school. In this broadened time of sitting, poor fitting furniture can cause various types of musculoskeletal disorders and discomforts. Thus, it is crucial to use anthropometric data to coordinate the arrangement of school furniture. To fulfill this perception, a survey has been conducted in 10 primary schools in Khulna, Bangladesh. Anthropometric measurements were accumulated from 300 students of these primary schools. Seven furniture dimensions were measured and fifteen anthropometric measurements were taken and they were compared to identify potential mismatch. A significant degree of mismatch was found between furniture and student anthropometric measurements. The results highlighted that desktop height and seat height were found too high and seat width was too small for all of the students. The paper also proposes furniture dimensions, which reduce mismatch percentage of students ranging from 90% to 10%.

“…One of the most commonly used methods in the development of standard systems, which was used in previous studies determining specifications of furniture for students, is the Ellipse methodology [17,49,50]. This method recommends an appropriate design range based on the fifth to 95th percentile dimensions of the collected anthropometric dimensions.…”

The naval multi-function console provides various types of information to the operator. It is equipment that is key for submarine navigation, and fatal human errors can occur due to the mismatch between the console specifications and the operator’s body size. This study proposes a method for deriving console specifications suitable for the body size of Korean users. The seat height, seat width, seat depth, upper edge of backrest, and worktable height were selected as the target design variables. Using six anthropometric dimensions, a mismatch equation for each target design variable was developed. Anthropometric measures of 2027 Korean males were obtained, and the optimal specifications of the console were derived via an algorithmic approach. As a result, the match rate, considering all the target design variables, was improved from 2.57% to 76.96%. In previous studies and standards, the optimal console specifications were suggested based on the anthropometric data of a specific percentile of users, and it was impossible to quantitatively confirm the suitability of the console design for the target users. However, the method used in this study calculated the match rate using the mismatch equation devised for comfortable use of the console and a large amount of anthropometric data that represented the user population, and therefore the improvement effect of the recommended specification can be directly identified when compared to the current specifications. Moreover, the methodology and results of this study could be used for deciding the specifications of multi-function consoles in several fields, including nuclear power plants or disaster situation rooms.
