A foldable chair, including a first bracket and a second bracket that are hingedly fixed in an X-shape, and an adjusting mechanism connecting an upper portion of the first bracket and a lower portion of the second bracket. The adjusting mechanism includes a fixing member and a movable member, the fixing member including a slide groove, and the movable member including a limit member movable within the slide groove; the slide groove has a serrated first inner side wall and a smooth second inner side wall, and the limit member is snapable to the first inner side wall.

A foldable chair includes a chair body having two rear legs, a metal seat movable upward and foldable on the rear legs so as to occupy little storage room. When the seat is moved to a seated position and when the rear legs are moved to a stretch-out position, the seat has a bottom edge seated on the top end of the rear legs and defines a straight line aligned with a middle line of the top end of the rear leg. An integrally formed strengthening structure extends across a bottom side of the seat so that gravity center of the seat is concentrated on the top ends of the rear legs, thereby strengthening the supporting ability of the rear legs relative to the seat so that even sitting of an overweight person on the seat does not deform and damage the seat and the rear legs.
