The height of school desks and chairs is related to the physical health of students, and schools attach great importance to the adjustment of school desk and chair height in the scope of school assessments. Make recommendations for the procurement of desks and chairs for the district education bureau. First, schools can save materials, targetly purchase desk and chair models that match the student's height and conform to the standard, and make standard height adjustments. Second, the annual inspection urges school teachers to pay attention to students' sitting posture, desk and chair height, and pay attention to their physical health. Special Situations may be fine-tuned The recommended heights for three additional classes have been adjusted appropriately in accordance with the student's existing realities. Take the guidelines for adjusting the height of desks and chairs for primary and secondary schools in the district of Gongshu, for example. A student whose height is 145cm, compared to the table and chair height table and chair model, meets the height of desk and chair models of 5 and 6, then he can adopt three types of desk and seat combination: desk 5 with desk 5, desk 6 with desk 6, desk 5 with table 6. Depending on the growth and development of the student's body, if some of the lower limbs are particularly long, or if the existing desks and chairs cannot stand upright to the floor due to the large drawers, In addition to the above three matching cases, appropriate fine-tuning is made in accordance with the principle of leg reach and foot landing, such as matching desk number 4 with desk number 4, desk number 4 and desk number 5 and desk number 4 between desk number 5 with desk number 6. The guide provides students with answers to six questions: What harms uncomfortable desks and chairs can do, What should a comfortable desk or chair be? What height should a desk or chair suit you? What can you do in general? What is the reason why a desk and chair are uncomfortable when adjusted to your height? What is correct to sit in? In this way, elementary and middle school students are reminded to pay attention to their sitting and desk and chair issues and take responsibility for their own health. Students can also take the guide home for parents to see, and at home also pay attention to sitting issues and cultivate good sitting habits. New ideas for schools worth learning From a price point, hand-shaking tables and chairs are several times more expensive than older ones. Each school will gradually update the new class tables and chairs in accordance with the financial situation and the scrapping of old tables and seats. The height of the desks and chairs is adjusted twice each semester, and the desks are walking with a brand name, which means that a set of desks and seats is with students for 3 years, and each desk and chair is branded with a name identification. In the past, students would change classrooms at each grade level, faced with a new set of desks and chairs, and the comfort level had to be readjusted. This situation can be avoided by following the desks and chairs. This also has the advantage of making desks and chairs specifically designed for students easier to confuse, while also ensuring that the quality, quality and service of such desks and seats are tracked in the school's use management. Daguan Elementary School has set up a "height tree" in the hallway to make it easier for students to measure it at any time. What does it take to sit right?

When it comes to children's sitting at home, mothers are in a state of "hating iron is not steel."The reporter randomly interviewed ten parents on WeChat Moments. Half of them had equipped their children’s homes with adjustable desks and chairs, and they were very concerned about the issue of classroom desks and chairs.The child's height is measured almost every month to see if the seat height needs to be adjusted. Parents are also careful about their children's sitting problems. In addition to verbal reminders, some have also used a sitting adjuster to prevent children from putting themselves on the table. For the healthy growth of the child, measure the child's height on time, set the table and chair, and urge the child to develop a good sitting position from an early age. At the same time, let the child be aware that if he or she grows taller, he or she should promptly tell the teacher or parents and adjust the desk and chair to the appropriate height.
