The present invention relates to a chair for supporting a human body by corresponding to postures of human using chairs and, more particularly, to the chair capable of improving the concentration of the human by properly supporting the human such as researchers sitting on the chair to be comfortable. The present invention provides stability and comfortability as the lower body of an operator is stably supported without being pushed from a seating unit and the upper body is supported by backrest in order for the weight of the operator to be dispersed with the seating unit. In case the operator is closely attached to a desk or a workbench in a state in which the spine of the operator is straight, the front femoral part of the operator applies large pressure to the front side of the chair. For improving this, the seating unit is formed to be smoothly rotated or fixed to the front in order for the distribution of the pressure applied to the femoral part to be equalized. If the upper body leans back for the rest, the seating unit is to be rotated or fixed. |
