Description of the Related Art [0004] A conventional chair, such as a swing chair, includes a seat portion, and a backrest portion extending upwardly from a rear side of the seat portion. However, the length of the seat portion usually supports only the buttocks and the upper leg portions of a user. The lower leg portions of the user are without support, and are hung freely. The conventional chair is not configured to provide support and comfort to the lower leg portions of the user. SUMMARY OF THE INVENTION [0005] Therefore, the object of the present invention is to provide a chair assembly that can provide leg support to thereby provide comfort to users and that is easy to use. [0006] According to this invention, a chair assembly comprises a chair unit including a seat frame, a seat member, and a leg support. The seat frame includes front and rear ends, and left and right first arms extending from the front to rear ends. The seat member is attached to the seat frame. The leg support includes a leg frame having left and right second arms which are connected pivotally and respectively to the left and right first arms at the vicinity of the front end, and a leg rest member attached to the leg frame. The leg support is movable between folded and unfolded positions. In the folded position, the leg rest member is superimposed on the seat member. In the unfolded position, the leg rest member extends forwardly from the seat member.
