To ensure children's health and safety, student furniture needs to check health indicators

Health and environmental protection is the first choice

The materials of children's desks and chairs are the same as those of children's furniture. They are rich in wood, wood-based panels, plastics, etc. These materials have their own characteristics, but they must be selected on the premise of sturdiness and practicality. Specifically, it requires environmental protection and no odor. The surface coating should have the characteristics of not fading and scratching, and the desk and chair that use plastic veneer or other harmless paint must be selected. Since children use desks to study almost every day, it is important to choose environmentally friendly products for everyday contact. This is precisely what many parents like to choose the log children's learning tables and chairs.

Don't be too fancy for children's tables and chairs

If you simply choose a children ’s desk and chair, do not choose too fancy shapes and patterns, otherwise it will easily distract your children and prevent them from focusing on their studies.

As part of the children ’s room, the choice of desks and chairs should match the room. 0-7 years old is the pinnacle of children's creativity development, it is best to use bold and bright colors to stimulate their curiosity and attention. Some studies have found that children who are more introverted and weak in character can choose brightly-colored and strong-contrast furniture; children with more irritable personality should use furniture with soft lines and light colors.

Desk-to-height ratio is appropriate

If the ratio of tables and chairs is not suitable, long-term use is not conducive to the child's physical development. The table is high and the chair is low, and children's long-term writing can easily cause myopia; the table is low and the stool is high, which often causes the child to hunch. Therefore, experts remind that the size of the desk and chair should be combined with the child's height, age and body shape, so as to benefit their healthy growth. In general, the standard of children's desks is 1.1-1.2 meters long, 0.76 meters high, and 0.55-0.6 meters wide; the standard of chairs is 0.4-0.44 meters high, which can basically meet the needs of primary and secondary school children.

If you do n’t want to change your child ’s desk frequently, choose a height-adjustable children ’s desk, so you can adjust it to your child ’s growth at any time, so that they can sit comfortably at every age. Desks and chairs with higher dimensions should have matching pedals to ensure that they can be laid flat after sitting down.
