What is the size of student desks and chairs to meet the normal use of students

Education is a major event in children’s life, but it is not easy to make children sit comfortably and listen in the classroom. According to some children’s feedback, their uncomfortable sitting in class will not only affect their physical development, but also reduce their learning efficiency. So the size of students’ desks and chairs is the primary consideration for contemporary schools to purchase desks and chairs. With the change of times, the development of school desks and chairs becomes more and more humanized, so what is the standard of students’ desks and chairs?

1. Seat height

The seat height of desks and chairs refers to the vertical distance from the front of the seat to the ground, which is one of the important factors affecting the fitness of sitting posture. The appropriate seat height should make the legs of the seated person naturally vertical. When the height of the seat surface is close to the height of the human calf plus the height of the foot, it is conducive to the rational distribution of the human pressure on the seat surface. Therefore, the seat height design of desks and chairs should strictly follow the leg and foot height values under human sitting posture.

2. Seat width

The size of the human hip and the appropriate range of motion determine the width of the seating surface of the desks and chairs. The seat width design of the student seat should consider the needs of those tall and strong students, so it should not be too narrow. Generally, it is better to be greater than or equal to 380mm, and it can also be determined by measuring the hip width.

3. Seat inclination

Because students keep leaning forward in reading and writing positions for a long time in class and self-study, if the front edge of desks and chairs is raised, it will exert great pressure on the body and the abdomen will also be severely squeezed. When leaning forward, when the angle between the thigh and the upper body is greater than 90 °, the body pressure distribution on the seat surface can be more reasonable.

4. Seat backrest

In the process of learning, when students lean back, the back support bears a certain body pressure load. If the back support is sufficient, students can look up at the blackboard or screen, greatly reducing the discomfort of cervical vertebra. Therefore, in order to distribute the weight of the backrest more, the height of the backrest should be higher than the height of the backrest point, and the height of the backrest should be 350~400mm.
