Folding armchair perfected, characterized by having articulated on the sides of the armchair two armrests, which have respectively articulated rods paths taking the form of a bridge, which bridge is fixed in different areas on the side of the chair to act as a buffer to adjust the position of the armrest, said armchair having eccentric pieces articulated respectively between the frame of the front legs and between two articulated tubes on each side of said chair, which have at least one recess operatively located to accommodate another rod in the form of a bridge, which is articulated to the frame of the front legs acting as a regulating stop for the chair's extensibility and representing the chair both end chains that join the frame of the backrest and the seat, so that the backrest acts anatomically under the pressure of the user's horn.
