  Here, the upholstery material 5 </ b> A is attached so as to form a space K between the pipe support 3. The space K is formed in an annular shape along the outside in plan view of the pipe support 3.

  In plan view, the center of the seat member 2 and the center of the base body 1 are arranged concentrically. The shape of the upper surface 21 </ b> B of the cushion material 21 is larger than the shape of the base plate 12. The upholstery material 5A is stretched along a surface connecting the corner portion 21D of the upper surface 21B of the cushion material 21 and the corner portion 12D of the lower surface 12C of the base plate 12. That is, between the cushion material 21 and the base plate 12, the upholstery material 5 </ b> A is stretched so as to incline gradually toward the center in plan view of the stool 100 as it goes downward from above. Thereby, the width of the space K is formed larger on the upper side than on the lower side.

  In the stool 100 configured as above, the upholstery material 5A covers the entire upper surface 21B of the cushion material 21 of the seat member 2, and the end 53A extends from the side surface 12B of the base plate 12 along the lower surface 12C of the base plate 12. It is stretched so as to be involved. A space K is formed between the pipe support 3 that connects the base plate 12 and the cushion base 22 and the upholstery material 5A. For example, in a chair provided with a core material that forms an outline between the leg member and the seat member, if the shape of the leg member and the shape of the seat member are different in plan view, the core material has a complicated shape. A local force is generated in the jacket material stretched along the core material. On the other hand, in the present invention, the upholstery material 5A can be freely deformed along the space K formed between the pipe support 3 and no local force is generated. Therefore, since it is suppressed that twist etc. arise in tension material 5A, tension material 5A can be tensioned without trouble.

  Further, the upholstery material 5A is stretched along the upper surface 21B of the cushion material 21, and is bent at the corner portion 12D of the cushion material 21 so as to follow the shape of the corner portion 12D. It is stretched in the acted state. Therefore, the appearance of the stool 100 can be configured by the upholstery material 5A that is stretched with an appropriate tension.

  The upholstery material 5 </ b> A covers the seat member 2 and is stretched up and down to the bottom of the base plate 12. Therefore, the stool 100 having a unified appearance can be provided by the upholstery material 5A stretched from the seat member 2 to the upper portion of the base body 1.

  In addition, since the plurality of pipe columns 3 connect the base body 1 and the seat member 2, the load of the seated person acting on the seat member 2 can be reliably supported by the plurality of pipe columns 3.

  Further, since the cushion material 21 on which the seated person sits has elasticity, it is possible to improve the sitting comfort. Further, since the cushion base 22 that supports the cushion material 21 is connected to the base body 1 via the pipe support 3, the load of the seated person acting on the cushion material 21 can be reliably supported.

  Further, since the end portion 53A of the upholstery material 5A is sandwiched between the lower surface 12C of the base plate 12 and the upper surface 11U of the skirt portion 11 and cannot be seen from the outside, the appearance of the stool 100 can be improved. Further, since the upholstery material 5A does not contact the floor surface, the upholstery material 5A is prevented from coming into contact with the floor surface and becoming dirty.

  In addition, since the adjuster 13 is provided on the center side of the stool 100 in a plan view with respect to the outer wall portion 11D and the inner wall portion 11B of the skirt portion 11, the user's feet and articles do not hit the adjuster 13, The adjuster 13 is not damaged or broken. Further, when viewed from the outside, the adjuster 13 cannot be visually recognized because it is hidden by the outer wall portion 11D and the inner wall portion 11B of the skirt portion 11, so that the stool 100 having excellent design can be provided.

  Further, since a core material such as a resin that constitutes the outer shell of the chair as in Patent Document 1 is not required, the weight can be significantly reduced. In addition, since a molding die for molding the resin is not required, significant cost reduction is possible.
