  • Patent number: 5918335
    Abstract: A baby pillow includes a base plate and two frames connected to two sides of the base plate. A cotton body surrounds each frame, and a layer of cotton cloth is made to cover the base plate and the two side cotton bodies. A soft cushion layer is formed with a cotton bag filled with cotton and then sewed with a side of the cotton cloth of the base plate, and then folded to overlap the base plate. The head of a baby may be laid on the soft cushion layer overlapped on the base plate, with the two side cotton bodies folded up to two sides of the head of the baby to help prevent the head from turning to a side, keeping it in a normal position, and preventing noise from reaching the ears of the baby to permit it to sleep soundly.
