The armrests of the standard children's desks and chairs are at a 90 degree angle, which establishes the right habits for children from childhood, and also limits the physical development, so that the spine and waist can be well developed.

Children's desks and chairs should be protected from direct sunlight. When placing high temperature objects, they must be cushioned with heat insulation mats. The desk should be placed in a place with sufficient light. If the children's desks and chairs are placed laterally, the light should be from the left side. Children's desks and chairs shall be as few as possible and placed against the wall to expand children's activity space. The height of children's desks and chairs is generally controlled at about 63cm. When children use them, they can be relatively tall and upright. If the height of the table is 63cm, the size of the matching chair should be controlled at about 30cm.
