Abstract

PROBLEM TO BE SOLVED: To provide an armchair in which a nesting can be accommodated. SOLUTION: From right and left rear legs 1a raised at forward inclination, front legs 1b inclined inward each other, directed forward and then suspended at rearward inclination are extended and extended parts 8 extended upward from the upper ends of both the rear legs 1a are formed. To the upper ends of the extended parts 8, elbow rests 3 slightly inclined upward and directed forward are attached. Seat back rods 7 having a seat back 2 attached to upper parts are provided upright at rearward inclination on short shafts 6 protruding from the upper ends of both the rear legs 1a so as to be opposed to each other. The rear part of a seat plate 4 is attached to the short shafts 6 so as to be rotatable about the short shafts 6. The seat plate 4 can collapse from a using position in which the seat plate 4 is mounted and supported on the upper parts of the right and left front legs 1b to an unused position in which the seat plate 4 is overlaid on the front part of the seat back 2.
