A chair, comprising:

• a backrest having a reference point and a lower end;
• a seat which includes
• a forward seat having a front end and a rear end, said forward seat being fixed in a horizontal position, and
• a rearward seat pivotally connected to said forward seat, said rearward seat being capable of swinging downward relative to said forward seat, said rearward seat having a rear end;
• a leg support having an upper end, said upper end of said leg support being pivotally supported to said front end of said forward seat;
• a tilting mechanism for connecting said rear end of said rearward seat and said lower end of said backrest so that said backrest is tiltable in a backward direction from a standing posture to a tilted posture, said tilting mechanism changing a positional relation between said rear end of said rearward seat and said lower end of said backrest so that a distance between the reference point and said rearward seat is reduced from the standing posture to the tilted posture as said backrest is tilted backward;
• and
• a connection mechanism for connecting said lower end of said backrest and a part of said leg support lower than said upper end of said leg support so as to cause said leg support to swing forward as said backrest is tilted backward,
• wherein said tilting mechanism comprises:
• a first link possessing a first end fastened by a hinge to said rear end of said rearward seat, and a second end fastened by a hinge to a middle position between said lower end of said backrest and the reference point, respectively;
• and
• a second link formed longer than said first link, said second link possessing a third end fastened by a hinge to a position of said rearward seat in front of the middle position, and a fourth end fastened by a hinge to said lower end of said backrest, respectively.
