Title: Training pillow
Inventor: BERENSTEIN BARRY M
IPC: A47G9/10
Filed: 2000-02-03
Abstract: A training pillow (10) to assist in teaching a person not to sleep face-down has a base portion (14) for supporting the back of the head when lying face-up on a sleeping surface and two side portions (16, 18) which project substantially diagonally from the base portion (14) and away from the sleeping surface.
