US Patent 7089616 Composite pillow

A composite pillow which prevents difference in level and a depression from being formed at a contact surface between divided core material parts, thereby prevents discomfort to a user. The composite pillow has core parts of different material or different hardness located at proper positions. The composite pillow is divided into a central part and a holding part for holding the central part by face-to-face contact and the parts are arranged in parallel. The central part and the holding part differ in hardness or material; and right and left contact surfaces of the holding parts contacting the central part and corresponding contact surfaces of the central part are diagonally formed.
