Abstract: A leg supporter structure for a chair seat plate, in which a leg supporter having a movable structure is mounted on a front end of a frame of a seat plate of a chair so that the leg supporter is rotated according to a user's body shape or posture, thereby softly supporting the user's popliteal part by minimizing pressure applied to the user's popliteal part. The leg supporter structure for a chair seat plate is applied to a chair seat plate to which a mesh member is combined with a frame of a predetermined shape, and includes: a lower frame of a rectangular shape; a U-shaped upper frame mounted along the upper surface of an outer wall of the lower frame; and a leg supporter of a bar shape which is mounted at an open front end of the upper frame to be selectively rotatable through rotary shafts disposed at both ends.

Abstract: The present disclosure relates to an assembly-type chair and provides an assembly-type chair that has a specific structure, thereby conveniently storing and transporting the chair with a minimized volume, and has a structure in which a chair body part including a seat plate and a backrest is rotatable, thereby effectively storing a plurality of chairs by stacking the chairs in the horizontal direction so as to be in close contact with each other.
