ABSTRACT:
A foldable lawn chair includes a seat frame, a backrest frame connected pivotally to a rear end of the seat frame, and two arm support frames at two sides of the seat frame. Each of the arm support frames has an armrest portion provided with a positioning member that has a longitudinal slot, front and rear ends, upper and lower peripheries extending between the front and rear ends, a row of positioning notches along the upper periphery, and an access hole integrally formed with the longitudinal slot. A slide plate is sleeved slidably on the positioning member and has a longitudinal slot and a through-hole that is formed integrally with and that is communicated with the longitudinal slot thereof. When the slide plate slides together with a positioning stud of the backrest frame along the positioning member, the positioning notches in the positioning member are respectively covered by the slide plate and are exposed through the through-hole of the slide plate.
