Design of the school chair mechanism for dynamic sitting

The aim of this research was to design a unique school chair with an adjustment mechanism for students from 5th to 8th grade, that would meet ergonomic and biomechanical requirements and provide comfortable and healthy sitting for students of different ages and anthropomeasures. The anthropometric measurements and an analysis of the existing school furniture with regard to ergonomic and biomechanical requirements were carried out in a primary school in the North of Croatia, on students from 5th to 8th grade. Based on the measured anthropomeasures and the biomechanical analysis of sitting, user needs were recognized and the list of requirements was made for designing a school chair. According to the list, solutions for individual parts of the adjustment mechanism were proposed and a concept with elaborated design was created. The mechanism allows adaptability of the chair to students of different ages and anthropomeasures, dynamic sitting and provides safety preventing injuries due to falls.
