A support pillow includes a pillow body having a medial region and two curved arms that extend from the medial region. The pillow body has a curved exterior periphery and an interior periphery that defines a well when the pillow is in an open position. A first flap portion extends from the exterior periphery of a first one of the curved arms and a second flap portion extends from the exterior periphery of a second one of the curved arms. A fastening mechanism is configured to couple the first and the second flap portions to each other when the pillow body is folded in half to place the pillow in a closed position, with the first and the second arms being generally adjacent to each other.
