Abstract: A system includes a support structure and a massaging device. The support structure has a width to span a user's torso and a depth to raise the user's torso off of an underlying surface when the user is in a prone position on the support structure. The massaging device is coupled to or embedded within the support structure at an offset location. The offset location allows the massaging device to be nearer to one lateral edge of the support structure than to an opposing lateral edge of the support structure, which in turn allows the user to dispose the massaging device approximately in alignment with the user's ileocecal valve. The massaging device also includes a control switch to control an operating state of the massaging device.
