“…Starting from the theories of sustainable development, circular economy, life cycle assessment, etc., the literature [8] proposed the concept and role of furniture green packaging based on a questionnaire survey of 15 furniture companies and established a furniture green packaging system framework. e literature [9] discussed the early stage of furniture design and its furniture design program evaluation theory. Moreover, it conducted surveys and analysis of consumer psychology questionnaires and design experts' attitude index to design evaluation indicators.…”

In today’s society, children’s furniture is an important piece of furniture for every household. Consumers and even companies may ignore its environmental merits since it is not a regular item of home furniture. This research focuses on the use of environmentally friendly materials in the design of children’s furniture and combines fuzzy technology with structured design technology to build a fuzzy technology-based children’s furniture design system. This research also introduces two intelligent systems for the design of children’s furniture, analyzes the structure of children’s furniture via structured design, and produces an interactive system with user experience. Finally, this component conducts a system test study based on real-world needs. The experimental research results show that the children’s furniture design system based on fuzzy technology proposed in this paper has a good user experience and can play an important role in the application of environmentally friendly materials in the design of children’s furniture.

Introduction: School tables and chairs are needed amongst many other facilities which support the teaching and learning activities. Uncomfortable tables and chairs can cause health problems. The purpose of this study is to design school table and chair sizes in accordance with anthropometry of elementary school students, so the tables and chairs do not cause health problems for children. Methods: The population used in this study was 72 students of elementary school students in Surabaya, and the sample size was 61 students. The sampling method used in this research was a simple random sampling. The anthropometric data measured were shoulder height in the sitting position, elbow height in the sitting position, popliteal-buttock length, knee height, popliteal height, shoulder width, and distance from elbow to fingertips. Meanwhile, the dimensions of tables and chairs measured were chair height, chair width, back length, back height, table height, table width, and underneath desk height. Results: The results of the research show that the sizes of existing tables and chairs are mismatched with student anthropometry. There are 7 dimensions of proposed table and chair sizes which are based on anthropometric data. Specifically, the chair height is 33.25 cm, chair width is 33.25 cm, backrest length is 46.50 cm, backrest height is 49.60 cm, table height is 56.85 cm, table width is 39.05 cm, and underneath desk height is 47 cm. Conclusion: The sizes of existing tables and chairs still need improvement in all dimensions based on the students’ anthropometric measurements.Keywords: anthropometry, chair, elementary school students, table

“…According to studies [11,18], anthropometric data obtained with the use of the traditional methods have been shown to be accurate and reliable as those obtained using some hi-tech equipment. Traditional methods have also been used for similar studies in Nigeria [14,15,19]. An anthropometer was used for taking all measurements of the participants while in sitting position.…”

“…Ergonomic designs which suit users and reduce discomfort resulting from use rely on a number of tools one of which is the anthropometric measures of the end-user [1]. Sadly, there is a dearth of information on the ergonomic suitability of educational furniture for students, especially in the higher institutions of learning in Nigeria [14], resulting in a large number of mismatch between anthropometric measures of users and furniture dimensions [15]. The design of DOI: https://dx.doi.org/10.17352/jbm.000017 classroom furniture for Nigerian schools with anthropometric measurements obtained from other parts of the world is unacceptable because body composition, size and shape have been reported to differ across races and nations [16].…”

Background: Ergonomic furniture design which is based on the application of the anthropometric measurements of the intended users does not only reduce the risk of developing musculoskeletal disorders such as low back pain, but also improves work performance. Aim: The main aim of this study was to survey and describe Nigerian University students based on important anthropometric measures relevant to ergonomic classroom furniture design. Method: A total of fi ve hundred and ninety (undergraduate and graduate) students where surveyed using the traditional methods of data capture. The measurement considered were the most important anthropometric features relevant to ergonomic furniture design. Result: The result of the survey was stratifi ed according to gender and age. Across all age groups, males had higher mean values for anthropometric measurement except for the hip width which was found to be higher in females than in males. When the participants were considered broadly as just males and females without consideration for their age groups, sexual dimorphism was seen to still exist. The males had higher mean values for all the anthropometric measurement except for hip width (males = 30.7±2.7cm; females = 33.9±3.7cm). Dimensions for ergonomic furniture design for the study population was also determined and presented. Conclusion: The study anthropometrically describes young Nigerians and therefore provides data which can be deployed by furniture designers for ergonomic product manufacture.

Abstract: In most underdeveloped and developing countries, the anthropometric dimensions of users are not deployed in classroom furniture design. This has severe health as well as learning implications. The aim of this study was to determine the ergonomic suitability of classroom furniture at the
