A nursing pillow has a flexible, positionable spine that allows the pillow to be deformed into a number of stable shapes. The spine is enclosed within a resilient body forming a medial region and first and second cantilever arms extending from opposite ends of the medial region to define a central opening between the arms in an unloaded, nominal shape. The spine is of sufficient stiffness to keep the pillow from returning from an adjusted shape to its nominal shape when unloaded. The spine may be formed of articulating links, or a malleable rod.
