The pillow is substantially wedge-shaped and has an appropriately shaped cavity in its upper surface for receiving and supporting the expanded abdomen of a pregnant woman lying on her side.

The combination of the resilient nature of the pillow and its geometrical configuration comfortably supports the expanded abdomen.
