Definitions

  • the present disclosure relates to a pillow with a sheet and a sheet.
  • Patent Document 1 discloses a structure that exerts a chiropractic effect on the user. According to this pillow, by forming it with a highly resilient material, the back of the head is prevented from sinking unnecessarily during use. Thereby, the pillow can adjust the user's posture during use and exert a chiropractic effect.
  • the pillow of Patent Document 1 is made of one homogeneous material. Therefore, if the user feels that the pillow is hard, it may be difficult to adjust the tactile sensation.
  • An object of the present disclosure is to provide a pillow with a sheet and a sheet that can easily adjust the feel of the pillow without impairing the therapeutic effect.
  • a pillow with a sheet according to one aspect of the present disclosure includes a pillow and a resin sheet stacked on the pillow.
  • the sheet according to one aspect of the present disclosure is stacked on the surface of the pillow on which the head is placed, and is made of resin.
  • the pillow can be adjusted to have a desired tactile feel. Further, in the use state, the user's head is placed on the pillow via the sheet. Thereby, the pillow with a sheet can provide the user with the tactile sensation of the sheet and stably support the user's head with the pillow. As a result, the pillow with a sheet and the sheet can easily adjust the feel of the pillow without impairing the therapeutic effect of the pillow.
  • FIG. 1 is a perspective view showing a pillow with a sheet in an embodiment of the present disclosure.
  • FIG. 1 is a schematic diagram showing how a pillow with a sheet is used in an embodiment of the present disclosure.
  • FIG. 7 is a top view showing a sheet in another embodiment of the present disclosure.
  • FIG. 7 is a top view showing a sheet in another embodiment of the present disclosure.
  • a pillow with a sheet 1 that supports the back of the user's M head will be described as an example.
  • the pillow with sheet 1 of this embodiment is installed on a mattress or futon.
  • the pillow with sheet 1 is formed to have a size in the width direction W, the front-rear direction L, and the height direction H, respectively.
