Desks and chairs for primary and secondary school students in China are an indispensable and important part of students' learning and life, and their size design is not only related to students' physical health, but also directly affects the learning effect. In China, the size of desks and chairs for primary and secondary school students is determined through a series of research on specifications and design concepts to ensure that students have a good learning experience and ensure the healthy growth of their bodies during the learning process.
First of all, the size of desks and chairs for Chinese primary and secondary school students refers to the principle of ergonomics to ensure that students do not experience discomfort when sitting for long periods of time. Generally speaking, the height of the student's desk is designed to take into account the student's height, so that the student's arms and wrists can be naturally stretched when writing and reading, and maintain a good learning posture. At the same time, the height of the chair has been carefully designed to ensure that the student's feet can land smoothly on the ground, preventing discomfort caused by prolonged sitting.
Secondly, the width and depth of desks and chairs for primary and secondary school students have also been determined by scientific research. The width of the desk should be large enough to accommodate students' books, stationery and other school supplies, so as to ensure that there is no space restriction when studying. At the same time, the depth of the table is designed to accommodate the needs of students writing and placing books, providing sufficient working space. The width and depth of the seats also take into account the differences in student body size, so as to provide a comfortable sitting position without wasting too much space.
In addition to the basic size design, the desks and chairs for Chinese primary and secondary school students also pay attention to humanized details. For example, some desk and chair designers also take into account the tilt of the table top to accommodate the visual needs of students when reading for a long time and reduce the burden on the cervical spine. The materials of the tables and chairs have also been carefully selected to ensure safety and environmental protection and avoid adverse effects on the health of students.
In China, the size of desks and chairs for primary and secondary school students also reflects the importance of education and the concern for students' physical and mental health. ** Desks and chairs are usually purchased according to relevant standards to ensure that the learning environment provided by the school meets the specifications and provides a good learning place for students.
The specific size of desks and chairs for primary and secondary school students in China varies according to the age group and grade level of the student. The following are the recommended size ranges in general:
1.*Dimensions of the table:**
Height: **Generally 700mm to 760mm, the specific height can be adjusted according to the student's height. Smaller students have lower desk heights to accommodate their height.
Width: Generally between 600mm and 700mm to provide enough space for writing and studying.
Depth: Generally between 400mm and 500mm to accommodate school supplies such as books, stationery, etc.
2.*Chair size:**
Seat height: Generally between 350mm and 420mm to ensure that students' feet can land smoothly.
Seat width: **Generally between 350mm and 400mm to accommodate the student's body width.
Seat Depth: **Generally between 300mm and 350mm, providing a comfortable seat depth.
In addition, some schools and institutions may also make individualized adjustments based on special needs or the student's physical condition. Overall, these dimensions are designed to provide students with a comfortable and healthy learning environment that promotes their holistic development through ergonomic design.
