Information
  The dangers of improper desks and chairs if students fail to achieve the standard: affecting vision, the height of the chairs and tables is the main factor affecting the correct writing posture of students, the desks and chairs are not matched properly, the students are not comfortable, and the writing postures are incorrect. It is easy to cause children to use their eyes too close, and students' vision quickly declines, the formation of myopia.
  Affect development
  Long-term bad posture is prone to neck and neck fatigue. Over time, it can lead to spinal deformity, humpback and cervical spondylosis. At the same time, abnormal bending can also interfere with the function and development of internal organs, cause rib and chest deformities, and cause cardiopulmonary dysfunction.
  Affect learning
  Non-ergonomic desks and chairs can also easily distract students and affect academic performance.
The "National Standards for Desks and Chairs" issued by the Ministry of Health in 1988 determined the height standards for desks and chairs for nine students of different heights. For example, students should be between 143 and 157 cm tall, the height of the desk should be 67 cm, the height of the empty space under the table should be 55 cm, and the height of the chair should be 38 cm. According to this regulation, the tables and chairs used in primary and secondary schools can be selected, but must meet the requirements of national standards. However, the survey found that the use of ordinary wooden chairs by most elementary schools did not meet the standards. Elementary schools equipped with desks for first-year students are 67.5 cm high, the open space under the table is 46.5 cm high, and the height of the chairs is 34.5 cm. Chen Xian, a member of the Child Health Professional Committee of the Preventive Medicine Association, explained that the height of this chair is a table and chair with high and low matching, which is likely to cause pupil distance and may cause students to use myopia in the past.
  Parents and students can select the appropriate desk and chair height according to the national standard "Functional Dimensions and Technical Requirements of School Desks and Chairs" (GB / t3976-2014).
  Among high school students with a standard height of 187.5 cm and elementary school freshmen of 112 cm, there should be 11 tables and chairs of different heights to choose from.
  Parents or students can measure by themselves to see if all the students' desks and chairs are qualified. If you are not qualified, you still need to respond to the school as soon as possible. Change the area to suit your child's desk, for the healthy growth of the child
