The present invention relates to a school classroom elastic chair. A lower end of a plurality of thin and long slots is opened from the lower end of a backrest of the chair to the upper part thereof and an upper end of the slots is closed, thereby having an abundance of elasticity in the backrest. The middle and lower part of the backrest is configured to move back and forth about the upper part, thereby a user does not feel tired even when sitting for a long time, as the chair provides comfort, and there is a big help effect in the prevention of spinal pain or scoliosis because the user instinctively moves his/her spine back and forth for spinal exercise. |
