a linkage assembly having a pantograph linkage set defining a legrest portion for supporting a user which is rotatable between a fully reclined and a fully extended position;
a base frame including first and second side channels; and
at least one tilt cam rotatably connected to the linkage assembly, the tilt cam including a plurality of substantially flat cam faces each oriented at an angle with respect to proximate ones of the cam faces, the cam faces defining a plurality of rotation positions of the mechanism by contact of individual ones of the cam faces with one of the first and second side channels to provide a positive stop at each rotated position.
