A lawn chair includes a backrest frame and two arm support frames provided at two opposite sides of the backrest frame. Each of the arm support frames has an armrest portion and a positioning member secured to the armrest portion and formed with a first longitudinal slot therethrough. A slide plate is sleeved slidably on the positioning member and has a second longitudinal slot unit of predetermined shaped formed therethrough. A positioning bolt extends through the first slot of the positioning member and the second slot unit of the slide plate and is threaded to the backrest frame. A protective sleeve member is sleeved over the armrest portion and is connected securely to the slide plate in such a manner that the protective sleeve member is movable together with the slide plate and that the protective sleeve member encloses the entire length of the positioning member therein. Thus, hands or clothes of the user are prevented from extending into the first longitudinal slot of the positioning member so as to prevent jamming between the positioning member and the slide plate.
