A chair includes a base to which a seat member is disposed, an L-shaped connecting plate extending from the base and a back member disposed to an upper end of the connecting plate. A mediate member is disposed to the base 10 and has two guides and each guide has a first slot defined longitudinally therethrough. The connecting plate has a transverse bar fixedly connected to a lower end thereof and the transverse bar is slidably received between the two first slots. An operation rod extends through the mediate member and an aperture defined in the lower end of the connecting plate so that the connecting plate is slidable and pivotable within the two first slots when removing the operation rod from the aperture of the connecting plate.
