acquiring the use of a garment having an elongate, position control member at the rear thereof and extending outwardly therefrom, said position control member being a continuous member having an inner surface, an outer surface, and an elongate, transverse dimension defined by transversely spaced-apart side surfaces, said side surfaces extending outwardly from the inner surface and being joined to the outer surface of said member at elongate side edges of the outer surface, said side surfaces tapering away from each other in a direction from the inner surface toward the outer surface whereby said outer surface has a elongate, transverse dimension greater than the elongate, transverse dimension of the inner surface at least one of, said side surfaces and side edges being located to engage a mattress or other sleeping surface when an individual wearing the garment is sleeping in a lateral position to aid in supporting the individual in a lateral position;

maintaining the garment about the torso of the individual with the elongate, transverse dimension of the position control member extending transversely along the back of the individual with the inner surface adjacent the back of the individual and the outer surface being spaced outwardly from the inner surface and from the back of the individual, whereby when said individual is in a lying position at least one of said side surfaces and side edges of said elongate, position control member assisting in maintaining said individual in a lateral position and providing an impediment to said individual moving into a supine position.
