The invention discloses a double folding chair with rotation angles. The double folding chair comprises four backrest pipes and two armrest pipes, wherein the a wrest pipes and the backrest pipes form a folding chair frame, rotation-angle transverse-bracing pipes are arranged between the two backrest pipes in the middle so that a flare angle can be formed between two chair backs, and intermediate connecting pieces which can rotate coaxially are arranged on a front support of the folding chair frame so as to be matched with the rotation-angle transverse-bracing pipes. Since the flare angle can be formed between two chair bodies, chair users can communicate conveniently, and the double folding chair has the advantages of being reasonable in structure, good in user experience etc.
