Abstract

A work chair is provided. The work chair comprises at least one rearward support wheel, at least one forward support wheel, at least two drive wheels and a height adjustable seat. The work chair further comprises a bogie base member. One of the at least two drive wheels are rotatably fixated to the bogie base member at a first fixation point, one of: a rearward support wheel and a forward support wheel are rotatably fixated to the bogie base member, at a second fixation point, and the bogie base member is adapted to have a pivot axis substantially between the first fixation point and the second fixation point. The pivot axis enables the wheels of the work chair to stay in contact with the ground surface, even when traveling over uneven surfaces.
