A folding chair has a seat component, a back component and a leg component. The seat component has a seat rear and a guide-support bar. The leg component comprises two pairs of legs, the first pair comprising a first and second leg and the second pair comprising a third and fourth leg. A cross member extends from the third leg to the fourth leg. The back component comprises a vertical element. The bottom of the vertical element is connected to the cross member and extends upwardly therefrom. The seat front is pivotally attached to the first and second legs and the seat rear is not connected to either the leg component or the back component, allowing the seat rear to slidably travel along vertical element. When the seat rear is at the vertical element top, the chair is in a folded configuration. When the seat rear is situated at the vertical element bottom, the chair is in a first sitting configuration. The vertical element includes at least one catch adapted to receive the guide-support bar and hold the seat rear such that the chair is in a second sitting configuration.
