Abstract: The reversible chair comprises two articulated portions (1, 2) with respect to a support (3), both articulated portions (1, 2) being able to be placed in a first position, wherein the articulated portion (1, 2) is in a substantially vertical position, and in a second position, wherein the articulated portion (1, 2) is in a substantially horizontal position, the chair further comprising two stop plates (4, 5), each of which is joined in rotation to one of the two articulated portions (1, 2), said stop plates (4, 5) being separated from each other when the two articulated portions (1, 2) are in the first position and in contact with each other when one of the articulated portions (1, 2) is in the second position. It provides a reversible chair that can be oriented in two different orientations and that is as simple and cheap as possible.
