A foldable armchair comprising a seat frame disposed in a first plane, and wheels rollingly supporting the frame. The wheels are carried by at least two legs rotatably mounted at their upper ends on the frame about first and second axes of rotation respectively. These first and second axes are substantially parallel to the first plane and coaxial, the other extremities of the two legs being connected to at least one roller by a device having at least two degrees of freedom of rotation. The two legs lie substantially in a second plane substantially parallel to the first plane. An upright is rotatably mounted about a third axis parallel to the first and second axes, and a bar interconnects the two legs. A telescoping lever variable in length between two limited positons, is rotatably mounted at one end on the upright and at its other end on the bar, so as to be able to drive the legs in rotation about the first and second axes.
