 a seat plate, from which two lateral plates extend downward, each having a hole in a middle position passed through by a hinge axis mounted on said frame, allowing said seat to be tilted forward and backward, and  
 a blocking assembly for restricting tilting forward and backward of said seat to maximum angles;  
   wherein by placing feet of a user on said supporting plates, movements of said user for controlling position and balance help to attain a healthy sitting position and proper orienting of vertebrae.    
   
   
       2 . The corrective chair according to  claim 1 , wherein a backrest is mounted on rear edges of said left and right plates, having an inclination angle that is adjustable by an adjusting device.
