Who will adjust the desks and chairs to the healthiest heights?
Children on the first day of the year, when the growth period. When I'm doing homework at home, I often bend my bow and shoulder for a long time. I'm a little hunchback.
This is because the chair is too high, so that the chair down, so that the children sit down, the eye height is about 8 inches to 9 inches higher than the table is appropriate, if you take into account the impact of eye, then this distance is best 10 inches
