Abstract: An n-shaped multifunctional pillow is provided, including a headrest portion and two armful pillow portions, in which the n-shaped multifunctional pillow includes an n-shaped pillow case, compartments are respectively disposed at two corners of the n-shaped pillow case, the compartments divide an internal cavity of the n-shaped pillow case into three storage spaces, and each storage space is filled with a soft material to form the headrest portion and the two armful pillow portions. The n-shaped multifunctional pillow can avoid the “cotton sliding phenomenon” and has a longer service life and better intensity. When in use, one of the two armful pillow portions which is at the side of the human back can be abutted against the human back.
