A foldable chair includes a main stick, a fold unit and a retention unit. The fold unit includes a middle slider member movable along the main stick between lower and upper positions, and a foldable support leg connected to the middle slider members. The retention unit is configured to prevent fold operation of the support leg when the middle slider member is at the lower position, and to permit the fold operation of the support leg when the middle slider member is at the upper position.
