Abstract A chair having supporting members for the seat and the shins, respectively, of a chair occupant, said supporting member being mechanically interconnected. A frame part (3; 25) interconnects the two supporting members (1, 2) and a supporting column (10) extends downward from said frame part (3; 25), and at its lower end is provided with a base (13; 14-18; 19-22) e.g. a base having legs, provided with roller members (23). A table assembly (32-41) may be attached to the chair through a transverse member (4) provided at the front and lowermost end of the frame part (3). The chair is intended for a kneeling-like sitting posture of a chair occupant.
