A foldable massage chair, including a face pillow assembly for supporting the head, a chest pillow assembly for supporting the chest, a handrail assembly for supporting wrists, a front support piece, a seat cushion assembly, a back support rod, a kneeboard assembly, a back supporting frame, and a front supporting frame. When a user needs to use this chair, it is placed in an expanded or use position, so the user may sit on the seat cushion and lean on the massage chair, completely exposing his back, waist, and hips for a masseur to massage. When the chair needs to be put away, it is possible to fold down the chair into a collapsed position by folding the seat cushion assembly, front support piece, chest pillow assembly, and handrail assembly. Also, the front supporting frame is folded towards the back supporting frame. Consequently, the size of the entire chair decreases.
