A back pillow, which forces persons to sleep on their sides in order to prevent snoring and a sleep apnoea syndrome, poses problems of biting-in straps of the back pillow and stiffening cloths around the shoulders, and involves a defect of being uncomfortable to use due to cushions that fail to response softly and smoothly. An attaching structure of a back pillow corrects the above problems and defects.
