A desk chair includes a seat with a back rest and a rigid frame joining the seat and backrest, and a pedestal base preferably with tilt and rotational capabilities. The chair is securely coupled to the base in the desk chair configuration but may be decoupled from the base and placed on the floor beside the base. To accomplish this arrangement, the chair is equipped with a set of four-and-aft extending rails that are integral with the frame which is attached to the seat. These rails rest on the floor only when the chair portion is decoupled from the pedestal base.
