Children spend most of their time on campus when they are three or four years old. How much do you know about the size of children's seats on campus? For example, in kindergarten, children use many types of seats, but in Bian Xiao, I mainly choose classroom seats to introduce them to you, because this is the most used and influential seat type for children. This child seat is 22*25*47cm, small and exquisite, which is very suitable for many children in kindergarten.
What is the size of a standard children's desk and chair?
The design of children's desks should conform to the principles of ergonomics, and the size of tables and chairs should of course match the height, age and body shape of children, so that children can grow up healthily. Generally speaking, the standard for children's desks is 1. 1 ~ 1.2m, with a height of 0.76m and a width of 0.55 ~ 0.6m What is the standard for a chair? 0.4~0.44 meters, the overall height is less than 0.8 meters, which can basically meet the needs of school-age children. However, as children grow up, their height is also increasing, and you don't want to change your children's desks frequently. You can choose a lifting children's desk with adjustable height.
The standard size of children's desks and chairs shall comply with the following standards:
1、? Chair seat surface: The chair seat surface inclines downward backward with an inclination angle of 0o ~ 2o. If the seat surface is concave along the center line, its radius of curvature is above 500mm. The front edge and two corners of the seat are obtuse.
2、? Back of the chair? Above the backrest point, it leans backward and forms an angle of 60 ~ 12O with the vertical plane. The front projection near the back is circular, and the upper and lower edges are processed into arcs. The curvature radius of the concave surface of the backrest is above 500mm. There is a gap between the lower edge of the backrest and the rear edge of the seat surface. Note: the backrest point is the most protruding point of the backrest forward on the center line of the chair. It is the basis of calculating the height of the upper and lower edges of the backrest, so that the backrest is supported at the waist back position under the shoulder angle.
3、? Product technical requirements and inspection methods: the allowable error range of desktop height and seat height is 2mm, and the allowable error range of backrest point from seat height is 15mm. See QB/T for other dimensional errors. 39 16.
4、? See QB/T for material requirements, process requirements, physical and chemical performance requirements of paint film, mechanical performance requirements and test methods. 39 16. The table top, seat surface and backrest of steel-wood tables and chairs are all made of wood. The paint film is light and uniform, close to the color of natural wood.
In fact, the choice of children's chairs should be based on the child's height, and the chair suitable for the child's height is the best chair. If the chair is not suitable, it will not only affect the child's hunchback, but also affect the child's development, so parents must take the choice of chair as an important thing and don't ignore the choice of chair. In addition, because the child's height is growing, the chair should be replaced accordingly, and a chair suitable for the child's height should be bought.
The above is about the size of children's chairs, I hope it will help everyone!
