Description

The present disclosure relates to a pillow that is held and used by the user.

Various types of body pillows have been conventionally known. Japanese Unexamined Patent Publication No. 2014-168607 describes a body pillow including a main body portion that can be held by the user and a headrest portion on which the user's head is placed. A microphone is embedded in the headrest portion, and the microphone is provided for recording the user's snoring, bruxism, and breath sounds.

Inside the main body, a balloon made of an elastic body such as rubber and having an ellipsoidal shape is embedded. A pressure air source is provided on the outside of the main body portion, and the pressure air source and the balloon are connected to each other by a flexible tube extending from the main body portion. A valve is provided at the outlet of the pressure air source, and by controlling the driving time of the pressure air source and the opening and closing of the valve, the bulge of the balloon is adjusted and the expansion and contraction of the body pillow is controlled.

Japanese Unexamined Patent Publication No. 2014-168607

The above-mentioned body pillow has a built-in balloon and is inflated by supplying air to the balloon. By the way, the dakimakura is often formed by a smooth curved surface, and in the case of a dakimakura having a smooth curved surface, the air permeability when holding the pillow may not be good. That is, since the user's arm or the like is applied to the smooth curved surface, there may be a problem that the arm or the like gets stuffy and the holding comfort is not comfortable. In the case of a body pillow having a smooth curved surface, the curved surface may be pressed against the arm or the like, which may increase the burden on the arm or the like.

An object of the present disclosure is to provide a body pillow that can improve breathability, reduce the burden on the arm and the like, and make the body comfortable to hold.

The body pillow according to the present disclosure is a columnar body pillow made of a flexible material, and has a convex portion extending along the longitudinal direction of the body pillow on the surface of the body pillow and a protrusion along the longitudinal direction on the surface. It is provided with an extending recess.

The body pillow is formed in a columnar shape, and includes a convex portion that protrudes on the surface and extends in the longitudinal direction of the body pillow, and a concave portion that is recessed on the surface and extends in the longitudinal direction. The body pillow is made of a flexible material and further includes a convex portion extending in the longitudinal direction and a concave portion extending in the longitudinal direction. Therefore, since a space is formed between the recess of the body pillow and the body of the user when the body is held by the user, it is possible to prevent stuffiness and improve the air permeability. Further, since the body pillow made of the flexible material is provided with the convex portion and the concave portion extending in the longitudinal direction of the body pillow, the flexible convex portion partially hits the user's arm or the like, so that the body or the like is covered. The burden can be eased. Therefore, it is possible to make a pillow that is comfortable to hold.

The above-mentioned body pillow includes a plurality of convex portions and a plurality of concave portions, and the convex portions and the concave portions may be alternately arranged along the circumferential direction of the body pillow. In this case, since the convex portions and the concave portions formed on the surface of the body pillow are alternately arranged along the circumferential direction, the formation of the space when the body is held and the relief of the burden on the arms and the like are more remarkable. Because it can be done, it can be more comfortable to hold.

The above-mentioned body pillow includes a plurality of recesses, and the plurality of recesses may include a first recess and a second recess deeper than the first recess. In this case, since two types of recesses, a first recess and a second recess deeper than the first recess, are provided, the air permeability can be further enhanced and the stuffiness can be further reduced.

The above-mentioned body pillow has a columnar shape, and may have a diameter of 10 cm or more and 35 cm or less. In this case, when the diameter of the body pillow is 10 cm or more and 35 cm or less, the size can be easily held by the arm, so that the comfort of holding can be further improved.

The above-mentioned body pillow has a plurality of convex portions, and the plurality of convex portions have a first convex portion extending along the longitudinal direction and a second convex portion having a length in the longitudinal direction shorter than the first convex portion. And may include. In this case, since the variation of the convex portion can be increased, the comfort of holding can be further improved by the various convex portions having high flexibility hitting the user's body.

The above-mentioned body pillow includes a plurality of convex portions, and the plurality of convex portions may include a first convex portion having a recess and a second convex portion having no recess. In this case, by including the first convex portion having a dent and the second convex portion having no dent, the variation of the unevenness formed on the surface of the body pillow can be further increased. Therefore, the comfort of holding can be made comfortable by the various highly flexible convex portions coming into contact with the arm or the like.

The above-mentioned body pillow may be provided with a slit that opens to the bottom surface of the recess and extends in the circumferential direction of the body pillow through the inside of the convex portion. In this case, since the body pillow is provided with a slit that opens in the bottom surface of the recess extending in the longitudinal direction and extends in the circumferential direction of the body pillow, the body pillow can be easily deformed. Therefore, since the breathability can be enhanced by the slit, a more comfortable hugging comfort can be provided to the user.

The above-mentioned body pillow may be provided with a through hole extending from one end surface to the other end surface in the longitudinal direction. In this case, since it is possible to secure an air flow path extending in the longitudinal direction inside the body pillow, it is possible to improve the air permeability and make it easily deformed. Therefore, it is possible to provide the user with a more comfortable sleeping comfort.

The above-mentioned body pillow has a plurality of through holes, and the plurality of through holes may be arranged radially on one end surface and the other end surface. In this case, since a plurality of through holes are formed, the air permeability can be further enhanced and the body pillow can be further deformed. Further, since the plurality of through holes are formed radially on one end surface and the other end surface, the air permeability and flexibility of the body pillow can be uniformly increased.

The above-mentioned convex portion may have a constricted portion in which the convex portion becomes thinner from the top of the convex portion toward the root portion. In this case, since the convex portion has a constricted portion, the convex portion can be easily deformed, so that the flexibility of the surface of the body pillow can be further increased.

The above-mentioned body pillow includes a surface layer forming convex portions and concave portions, and a core located inside the surface layer, and the hardness of the surface layer may be lower than the hardness of the core. In this case, since the hardness of the core located inside the surface layer is higher than the hardness of the surface layer, the core can firmly support the user's body. Further, since the hardness of the surface layer is lower than the hardness of the core, the flexibility of the surface can be increased, so that the comfort of holding can be further improved.

The above-mentioned surface layer includes a first material layer forming a convex portion and a second material layer forming a concave portion, and the first material layer may be made of non-film urethane. In this case, since the non-membrane urethane has a coarser mesh than other types of urethane, the air permeability of the convex portion can be improved. Therefore, it contributes to further improvement of air permeability.

According to the present disclosure, it is possible to improve the air permeability and reduce the burden on the arm and the like to make the hugging comfort comfortable.

FIG. 1 is a perspective view showing a body pillow according to an embodiment. FIG. 2 is a side view of the body pillow of FIG. FIG. 3 is an enlarged view of a part of the side view of FIG. FIG. 4 is a sectional view taken along line IV-IV of FIG.

Hereinafter, embodiments of the body pillow according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are designated by the same reference numerals, and duplicate description will be omitted as appropriate. In addition, the drawings may be partially simplified or exaggerated for the sake of easy understanding, and the dimensional ratios and the like are not limited to those described in the drawings.

FIG. 1 is a perspective view showing a body pillow 1 according to the present embodiment. FIG. 2 is a side view showing the body pillow 1. As shown in FIGS. 1 and 2, for example, the body pillow 1 has a columnar shape centered on an axis extending from the center C of one end surface 1b along the longitudinal direction D1, and the entire body pillow 1 is formed. It is made of flexible material. In the present embodiment, the cross-sectional shape when the body pillow 1 is cut in a cross section orthogonal to the longitudinal direction D1 is circular.

The length L1 of the body pillow 1 in the longitudinal direction D1 is, for example, 60 cm or more and 150 cm or less, and as an example, it may be 77 cm or more and 88 cm or less. The diameter L2 of the body pillow 1 is, for example, 10 cm or more and 35 cm or less, and as an example, it may be 20 cm or more and 22 cm or less.

The body pillow 1 includes a surface layer 10 including the side surface of the body pillow 1 and a core 4 located inside the surface layer 10. The surface layer 10 includes a first material layer 2 that forms the surface of the body pillow 1 and a second material layer 3 that is located inside the first material layer 2. For example, the body pillow 1 has a three-layer structure of a first material layer 2, a second material layer 3, and a core 4, and the materials of the first material layer 2, the second material layer 3, and the core 4 are different from each other. ing. As an example, the core 4 and the second material layer 3 are adhered to each other by an adhesive, and the first material layer 2 is adhered to the second material layer 3 by an adhesive.

For example, the first material layer 2 forms a convex portion 5s, which will be described later, and the second material layer 3 has a cylindrical shape in which a concave portion 5c is formed on the surface. As an example, the color of the first material layer 2, the color of the second material layer 3, and the color of the core 4 are different from each other, which enhances the design of the body pillow 1.

The first material layer 2 is made of, for example, non-membrane urethane, and the second material layer 3 and the core 4 are made of urethane. For example, the hardness of the first material layer 2 is harder than the hardness of the second material layer 3 and softer than the hardness of the core 4. The surface layer 10 has an unevenness 5f that is aligned along the circumferential direction D2 of the body pillow 1 and extends along the longitudinal direction D1.

The body pillow 1 has, for example, a first region 2b, a second region 2c, a third region 2d, a fourth region 2f, and a fifth region 2g. As an example, the second region 2c and the fourth region 2f correspond to the place where the user's arm is applied, and are softer than the other regions (first region 2b, third region 2d, and fifth region 2g). The area.

For example, the length of the second region 2c in the longitudinal direction D1 and the length of the fourth region 2f in the longitudinal direction D1 are the length of the first region 2b in the longitudinal direction D1 and the length of the fifth region 2g in the longitudinal direction, respectively. Shorter than each of the lengths of D1. As an example, the length of the third region 2d in the longitudinal direction D1 is longer than the length of the first region 2b in the longitudinal direction D1 and the length of the fifth region 2g in the longitudinal direction D1.

For example, in the first region 2b, the second region 2c, the third region 2d, the fourth region 2f, and the fifth region 2g, the shapes and sizes of the irregularities 5f are different from each other. In the present embodiment, the shape of the unevenness 5f of the first region 2b and the shape of the unevenness 5f of the second region 2c are different from each other. The body pillow 1 has a convex portion 5s extending in the longitudinal direction D1 and a concave portion 5c extending in the longitudinal direction D1. The convex portion 5s includes a first convex portion 5b, a second convex portion 5m, and a third convex portion 5p, which will be described later.

For example, the body pillow 1 has a shape symmetrical with respect to a plane that passes through the center of the body pillow 1 in the longitudinal direction D1 and extends along the circumferential direction D2. In this case, the first region 2b and the fifth region 2g have the same shape as each other, and the second region 2c and the fourth region 2f have the same shape as each other.

When the body pillow 1 has a symmetrical shape as described above, it can be used without worrying about the orientation of the body pillow 1, so that the usability can be improved. Further, the fifth region 2g may have the same shape as the first region 2b, and the fourth region 2f may have the same shape as the second region 2c. Therefore, in the following, the description of the shapes of the fourth region 2f and the fifth region 2g will be omitted as appropriate.

FIG. 3 is a side view of the body pillow 1 in which the first region 2b, the second region 2c, and the third region 2d are enlarged. As shown in FIGS. 2 and 3, the boundary between the first region 2b and the second region 2c, the boundary between the second region 2c and the third region 2d, the boundary between the third region 2d and the fourth region 2f, and the fourth An annular recess 5h is formed at each of the boundary between the region 2f and the fifth region 2g. For example, the depth of the annular recess 5h is deeper than the depth of the recess 5c.

The first convex portion 5b has a recess 5g recessed on the surface of the first convex portion 5b, for example, the recess 5g is recessed in a U shape. The recess 5g is formed, for example, near the center of the first convex portion 5b in the longitudinal direction D1. As an example, the depth of the recess 5g is shallower than the depth of the first convex portion 5b, and the recess 5g is formed only in the first material layer 2 (not in the second material layer 3).

The position of the recess 5g formed in the first convex portion 5b in the longitudinal direction D1 and the position of the recess 5g formed in the first convex portion 5b adjacent to the circumferential direction D2 in the longitudinal direction D1. May be identical to each other. In this case, the recess 5g is formed so as to be continuous along the circumferential direction D2 between the plurality of first convex portions 5b.

The body pillow 1 includes, for example, a slit 5j that passes through the inside of the first convex portion 5b in the radial direction, opens at the bottom surface 5k of the concave portion 5c, and extends in the circumferential direction D2. The slit 5j extends along the circumferential direction D2 on the radial inside of the body pillow 1 with respect to the bottom surface 5k of the recess 5c. As an example, one slit 5j is formed between the recess 5g and the annular recess 5h. In the first region 2b, the slit 5j is formed on the second region 2c side (opposite side to one end surface 1b of the body pillow 1) with respect to the recess 5g.

The second region 2c has a second convex portion 5m and a concave portion 5c extending in the longitudinal direction D1. For example, the recess 5c is continuous from one end surface 1b of the body pillow 1 to the other end surface 1c. The second convex portion 5m and the concave portion 5c are alternately arranged along the circumferential direction D2. The second region 2c includes a plurality of second convex portions 5 m arranged along the longitudinal direction D1, and an annular concave portion 5h is formed between the two second convex portions 5 m arranged along the longitudinal direction D1. .. As an example, the second region 2c includes three second convex portions 5m arranged along the longitudinal direction D1 and two annular recesses 5h arranged along the longitudinal direction D1.

As described above, the body pillow 1 includes a plurality of convex portions 5s, and the plurality of convex portions 5s have a first convex portion 5b extending along the longitudinal direction D1 and a length in the longitudinal direction D1. It includes a second convex portion 5m shorter than the first convex portion 5b. As described above, the first convex portion 5b has a recess of 5 g, and the second convex portion 5 m does not have a recess of 5 g.

For example, a slit 5j extending in the circumferential direction D2 is formed inside the second convex portion 5m in the radial direction, and the slit 5j opens to the bottom surface 5k of the concave portion 5c. The first region 2b has one slit 5j along the longitudinal direction D1, while the second region 2c has a plurality of (three, for example) slits 5j along the longitudinal direction D1. Therefore, the second region 2c is a region softer than the first region 2b. Further, the first region 2b does not have an annular recess 5h, whereas the second region 2c has (a plurality of) annular recesses 5h (as an example), and in this respect as well, the second region 2c is more than the first region 2b. Is also considered to be a soft area.

The third region 2d has a third convex portion 5p and a concave portion 5c extending in the longitudinal direction D1. The third convex portion 5p and the concave portion 5c are alternately arranged along the circumferential direction D2. For example, the third convex portion 5p has a recess 5g. The third convex portion 5p may have, for example, a plurality of (three as an example) recesses 5g, and the plurality of recesses 5g may be arranged at equal intervals along the longitudinal direction D1.

The position of the recess 5g formed in the third convex portion 5p in the longitudinal direction D1 and the position of the recess 5g formed in the third convex portion 5p in the longitudinal direction D1 adjacent to the circumferential direction D2. May be the same as each other. That is, the recess 5g may be formed so as to be continuous along the circumferential direction D2 between the plurality of third convex portions 5p.

A slit 5j extending in the circumferential direction D2 is formed inside the third convex portion 5p in the radial direction. The third region 2d has, for example, a plurality of slits 5j, and the plurality of slits 5j are arranged along the longitudinal direction D1. As an example, in the third region 2d, the slits 5j and the recesses 5g are alternately arranged along the longitudinal direction D1.

As an example, the third region 2d includes four slits 5j arranged along the longitudinal direction D1 and three recesses 5g arranged along the longitudinal direction D1. The distances between the slit 5j and the recess 5g in the longitudinal direction D1 may be the same as each other. The hardness of the third region 2d is, for example, about the same as the hardness of the first region 2b and the hardness of the fifth region 2g. Further, the hardness of the third region 2d is, for example, about the same as the hardness of the second region 2c and the hardness of the fourth region 2f. However, since the second region 2c and the fourth region 2f are finely formed with slits and the like, they are easier to move than the first region 2b, the third region 2d, and the fifth region 2g.

FIG. 4 is a sectional view taken along line IV-IV of FIG. As shown in FIGS. 1 and 4, the body pillow 1 includes, for example, a surface layer 10 forming a convex portion 5s and a concave portion 5c, and a core 4 located inside the surface layer 10. The surface layer 10 includes a first material layer 2 that forms the convex portion 5s and a second material layer 3 that forms the concave portion 5c.

The body pillow 1 includes a plurality of convex portions 5s and a plurality of concave portions 5c, and the convex portions 5s and the concave portions 5c are alternately arranged along the circumferential direction D2 of the body pillow 1. As an example, the number of convex portions 5s and the number of concave portions 5c are 33. However, the number of convex portions 5s and the number of concave portions 5c can be appropriately changed, for example, 1 or more and 65 or less, 2 or more and 50 or less, 3 or more and 45 or less, 5 or more and 45 or less, or 10 or more. And it may be 40 or less. Further, the number of convex portions 5s and the number of concave portions 5c may be different from each other.

For example, the convex portion 5s has an inverted U shape. The convex portion 5s may have a top portion 5t and a root portion 5v, and may further have a constricted portion 5w that becomes thinner from the top portion 5t toward the root portion 5v. The recess 5c includes, for example, a first recess 5q and a second recess 5r deeper than the first recess 5q. The first recesses 5q and the second recesses 5r may be arranged alternately along the circumferential direction D2, for example. For example, a plurality of (two as an example) first recesses 5q are arranged between the pair of second recesses 5r.

For example, the number of the first recesses 5q is larger than the number of the second recesses 5r. As an example, the number of the first recesses 5q is 22, and the number of the second recesses 5r is 11. However, the number of the first recesses 5q, the number of the second recesses 5r, and the ratio of the number of the first recesses 5q to the number of the second recesses 5r can be changed as appropriate.

The core 4 is arranged radially inside the body pillow 1 of the convex portion 5s and the concave portion 5c. For example, the hardness of the core 4 is higher than the hardness of the surface layer 10. In this case, the core 4 is harder than the surface layer 10. The core 4 is, for example, cylindrical. The core 4 has, for example, a through hole 4b extending from one end surface 1b in the longitudinal direction D1 to the other end surface 1c.

As an example, the through hole 4b communicates with the slit 5j inside the body pillow 1. That is, in the body pillow 1 according to the present embodiment, a through hole 4b that opens on one end surface 1b in the longitudinal direction D1 and a slit 5j that opens on the side surface of the body pillow 1 are formed. As described above, since the body pillow 1 has a through hole 4b that opens on one end surface 1b and a slit 5j that opens on the side surface, it has very high air permeability and flexibility.

For example, the core 4 has a plurality of through holes 4b. As an example, the plurality of through holes 4b are arranged radially on one end surface 1b and the other end surface 1c. The plurality of through holes 4b are arranged so as to be arranged along the circumferential direction D2, and are, for example, arranged at equal intervals along the circumferential direction D2. As an example, the body pillow 1 is provided with 10 through holes 4b, and the 10 through holes 4b are arranged at equal intervals along the circumferential direction D2.

For example, the through hole 4b has a first inner surface 4c and a second inner surface 4f extending radially inward from the outer surface of the core 4, and a radial inner end of each of the first inner surface 4c and the second inner surface 4f. It has an expansion hole portion 4d that extends from the portion. The first inner surface 4c and the second inner surface 4f face each other along the circumferential direction D2, and extend in parallel with each other, for example.

The expansion hole portion 4d extends in an arc shape from the radial inner ends of the first inner surface 4c and the second inner surface 4f. By having the expansion hole portion 4d in which the through hole 4b expands in the radial direction, the portion between the pair of through holes 4b arranged along the circumferential direction D2 can be more easily deformed, so that the air permeability is improved. At the same time, it is possible to provide a more comfortable sleeping comfort to the user of the body pillow 1.

Next, the action and effect obtained from the body pillow 1 according to the present embodiment will be described in detail. The body pillow 1 is formed in a columnar shape, and includes a convex portion 5s that protrudes on the surface and extends in the longitudinal direction D1 of the body pillow 1, and a concave portion 5c that is recessed on the surface and extends in the longitudinal direction D1. The body pillow 1 is made of a flexible material, and further includes a convex portion 5s extending in the longitudinal direction D1 and a concave portion 5c extending in the longitudinal direction D1. Therefore, since a space is formed between the recess 5c of the body pillow 1 and the body of the user when the body is held by the user, it is possible to prevent stuffiness and improve the air permeability.

Further, since the body pillow 1 made of the flexible material is provided with the convex portion 5s and the concave portion 5c extending in the longitudinal direction D1 of the body pillow 1, the flexible convex portion 5s partially hits the user's arm or the like. Therefore, the burden on the arm and the like can be alleviated. Therefore, the body pillow 1 can be comfortable to hold.

Further, the body pillow 1 may include a plurality of convex portions 5s and a plurality of concave portions 5c, and the convex portions 5s and the concave portions 5c may be alternately arranged along the circumferential direction D2 of the body pillow 1. In this case, since the convex portions 5s and the concave portions 5c formed on the surface of the body pillow 1 are alternately arranged along the circumferential direction D2, the space is formed when the body is held and the burden on the arms and the like is alleviated. Can be made more prominent, so that the comfort of holding can be made more comfortable.

Further, the body pillow 1 may include a plurality of recesses 5c, and the plurality of recesses 5c may include a first recess 5q and a second recess 5r deeper than the first recess 5q. In this case, since two types of recesses 5c, a first recess 5q and a second recess 5r deeper than the first recess 5q, are provided, the air permeability can be further improved and the stuffiness can be further reduced.

Further, the body pillow 1 has a columnar shape, and the diameter L2 may be 10 cm or more and 35 cm or less. In this case, when the diameter L2 of the body pillow 1 is 10 cm or more and 35 cm or less, the size can be made easy to hold with the arm, so that the comfort of holding can be further improved.

Further, the body pillow 1 includes a plurality of convex portions 5s, and the plurality of convex portions 5s have a first convex portion 5b extending along the longitudinal direction D1 and a first convex portion having a length in the longitudinal direction D1. A second convex portion 5 m shorter than 5b may be included. In this case, since the variation of the convex portion 5s can be increased, the comfort of holding can be further improved by the various convex portions 5s having high flexibility hitting the user's body.

Further, the body pillow 1 may include a plurality of convex portions 5s, and the plurality of convex portions 5s may include a first convex portion 5b having a recess 5g and a second convex portion 5m having no recess 5g. In this case, by including the first convex portion 5b having the depression 5g and the second convex portion 5m having no depression 5g, the variation of the unevenness 5f formed on the surface of the body pillow 1 can be further increased. Therefore, various highly flexible convex portions 5s can be brought into contact with the arm or the like to make the hugging comfort comfortable.

Further, the body pillow 1 may be provided with a slit 5j that opens to the bottom surface 5k of the recess 5c and extends in the circumferential direction D2 of the body pillow 1 through the inside of the convex portion 5s. In this case, since the body pillow 1 is provided with a slit 5j that opens in the bottom surface 5k of the recess 5c extending in the longitudinal direction D1 and extends in the circumferential direction D2 of the body pillow 1, the body pillow 1 can be easily deformed. it can. Therefore, since the breathability can be enhanced by the slit 5j, a more comfortable holding comfort can be provided to the user.

Further, the body pillow 1 may be provided with a through hole 4b extending from one end surface 1b in the longitudinal direction D1 to the other end surface 1c. In this case, since the air flow path extending in the longitudinal direction D1 can be secured inside the body pillow 1, the body pillow 1 can be easily deformed while improving the air permeability. Further, since the plurality of through holes 4b are formed radially on one end surface 1b and the other end surface 1c, the air permeability and flexibility of the body pillow 1 can be uniformly increased.

Further, the convex portion 5s may have a constricted portion 5w in which the convex portion 5s becomes thinner from the top portion 5t of the convex portion 5s toward the root portion 5v. In this case, since the convex portion 5s has the constricted portion 5w, the convex portion 5s can be easily deformed. More specifically, since each convex portion 5s can be easily deformed in the circumferential direction D2 so that each convex portion 5s moves in the circumferential direction D2, the flexibility of the surface of the body pillow 1 can be further enhanced. it can.

Further, the body pillow 1 includes a surface layer 10 having a convex portion 5s and a concave portion 5c, and a core 4 located inside the surface layer 10, and the hardness of the surface layer 10 is higher than the hardness of the core 4. It may be low. In this case, since the hardness of the core 4 located inside the surface layer 10 is higher than the hardness of the surface layer 10, the core 4 can firmly support the user's body. Further, since the hardness of the surface layer 10 is lower than the hardness of the core 4, the flexibility of the surface layer 10 can be increased, so that the comfort of holding can be further improved.

Further, the surface layer 10 includes a first material layer 2 forming the convex portion 5s and a second material layer 3 forming the concave portion 5c, and the first material layer 2 is made of non-film urethane. You may. In this case, since the filmless urethane has a coarser mesh than other types of urethane, the air permeability of the convex portion 5s can be improved. Therefore, it contributes to further improvement of air permeability.

The embodiment of the body pillow according to the present disclosure has been described above. However, the body pillow according to the present disclosure is not limited to the above-described embodiment, and may be modified as long as the gist described in each claim is not changed. That is, the shape, size, number, material, and arrangement of each part of the body pillow can be appropriately changed without departing from the above gist.
