Abstract:
1. A pillow having a plurality of polygonal units, comprising: a central normal sleep pillow portion comprising: a plurality of triangular pentahedron units, each of which having a shape of a triangular prism that is triangular in cross-section, so that the plurality of triangular pentahedron units are configured to provide a cervical vertebral part; two one-side inclined square hexahedral units, each of which having a shape of a square pillar that is square in cross-section, with a one-side inclined surface thereof being inclined; and a rectangular hexahedron unit having a shape of a rectangular pillar that is rectangular in cross-section and disposed between the two one-side inclined square hexahedral units, so that the two one side inclined square hexahedral units and the rectangular hexahedron unit are configured to provide an occipital-region support part; and two sideways pillow portions, one disposed on each side of the central normal sleep pillow portion, wherein each of the two sideways pillow portions comprises: a first plurality of isosceles-triangular pentahedron units, each of which having a shape of an isosceles triangular prism that is isosceles triangular in cross-section, wherein the first plurality of isosceles-triangular pentahedron units are disposed on a same plane as a bottom surface of the central normal sleep pillow portion; a plurality of rhombic hexahedron units, each of which having a shape of a rhombic pillar that is rhombic in cross-section, wherein the plurality of rhombic hexahedron units are stacked on the plurality of isosceles-triangular pentahedron units; a second plurality of isosceles-triangular pentahedron units, each of which having a shape of an isosceles triangular prism that is isosceles triangular in cross-section, wherein the second plurality of isosceles-triangular pentahedron units are disposed on an elevated plane parallel to the bottom surface of the central normal sleep pillow portion; and two rectangular hexahedron units, each of which having a shape of a rectangular pillar that is rectangular in cross-section and disposed on the second plurality of isosceles-triangular pentahedron units, so that the two rectangular hexahedron units are configured to provide an ear-press prevention recess, whereby the units are sewn together in such a way so as to selectively come into surface contact with each other or be stacked, thus forming one pillow, with the respective units being filled with stuffing.
