The leisure chair frame comprises at least two parallel spaced first cross frames, each of the first cross frames comprises two cross pivoted first connecting rods, the upper end of each of the first connecting rods is provided with an upper seat, the lower end of each of the first connecting rods is provided with a lower sat; and a second cross frame is pivoted between adjacent two first cross frames. Two lower seats positioned at the rear side of each of the first cross frames are respectively fixedly provided with a vertical rod, and the upper end of the vertical rod traverses through the upper seat in a sliding manner. Each of the first cross frames is provided with an inclined backrest rod, one end of the inclined backrest rod is pivoted to the upper end of the vertical rod, the other end of the inclined backrest rod is movably connected with the first cross frame, and the vertical rod, the inclined backrest rod and one of the first connecting rods of the cross frames form a triangular structure when the first cross frames are positioned in unfolding state. The folding leisure chair frame enables an angle between a backrest cloth and a seat clot to be greater than 90DEG, has high comfortableness, can prevent the tip-back of the folding chair, has a high support stability, can prevent the near distance between the two inclined backrest rods, and avoids the wrapping of a user by the backrest cloth.
