1. A seat including a head rest whose height is adjustable, comprising:
- a seat cushion designed to be slidably disposed on a floor;
a seat back connected to the seat cushion and rotatable relative to the seat cushion;
the head rest disposed adjacent the top of the seat back and adjustable in height relative to the seat back;
an inclining mechanism for inclining the seat back relative to the seat cushion;
a sliding mechanism for sliding the seat cushion relative to the floor;
a moving mechanism for moving the head rest towards and away from the top of the seat back; and
an interlocking mechanism for interlocking the moving mechanism for moving the head rest with each of the inclining mechanism for inclining the seat back relative to the seat cushion and the sliding mechanism for sliding the seat cushion relative to the floor such that said sliding of the seat cushion or inclining of the seat back results in movement of the headrest in height relative to the seat back.
