Ergonomic application: The design of the chair back should conform to the physiological curve of the human spine, providing good support for the student’s back and reducing the pressure on the waist. The seat surface of the chair should have a certain inclination so that the student’s buttocks can be fully supported while avoiding fatigue caused by long-term sitting. In addition, the edges of the desks and chairs should be rounded to avoid sharp corners causing harm to students.
Color matching: The colors of the desks and chairs should be simple and bright, such as light blue, light yellow, etc., which can bring comfortable visual experience to students and improve their enthusiasm for learning. Avoid using overly bright or dazzling colors to avoid distracting students.
