Ergonomical pillow for head rest

An ergonomic pillow for head rest, comprising:

• a pillow surface, which is a sheet-like element made from a soft buffer material;
• a pillow comprising soft buffer material, and having a first hollow compartment, a left hollow compartment, and a right hollow compartment inside, with the left and right hollow compartments disposed on two opposite sides of the first hollow compartment, wherein the first hollow compartment extends away from a top surface of the pillow by a first depth, the left hollow compartment extends away from the top surface by a second depth, the right hollow compartment extends away from the top surface by a third depth, the first hollow compartment is disposed in an essential location configured to be in alignment with a user's head, and the first depth is larger than the second and third depths;
• a shock absorbing and pressure relief cushion being a sheet-like element and covering the pillow, wherein the shock absorbing and pressure relief cushion has a bottom surface connecting to the top surface of the pillow and covering the first, left and right hollow compartments, and the shock absorbing and pressure relief cushion further has a top surface opposite to the bottom surface and adapted to face the user's head;
• and
• a covering layer covering the shock absorbing and pressure relief cushion;
• wherein the pillow surface is arranged between the shock absorbing and pressure relief cushion and the covering layer;
• wherein the pillow has a top layer material and a bottom layer material that are made from soft buffer material and overlap with each other, wherein the top layer material and the bottom layer material connect with each other, wherein the bottom layer material forms a first central compartment, wherein the top layer material forms a second central compartment in connection with the first central compartment so that the first and second central compartments jointly form the first hollow compartment, wherein the left hollow compartment and the right hollow compartment are formed in the top layer material on two opposite sides of the second central compartment.
