1. A multilayer, one-piece, disposable diaper comprising a liquid-impervious backing layer having sufficient longitudinal and transverse dimensions for encircling the thigh and waist regions of a wearer, a fluid-absorbent pad adapted to be disposed in the perineal region of the wearer for receiving and retaining body fluids, said pad constituting the primary absorbent component, by weight, of the diaper and being superposed on said backing layer and means for providing adjustable movement between said backing layer and said pad comprising bonding means securing the fluid-absorbent pad to the backing layer over only a limited region disposed inwardly of at least two corners of said pad for permitting marginal sections of the pad which constitute at least 50% of the total pad area to move independently of the backing layer.
