Therefore, it is possible to provide a highly usable chair 101 that can be nested from a plurality of directions, without the need to align the legs 120 in the nesting direction during nesting.
  • the above example shows an example in which the front leg x is smaller than the rear leg x ′ in the front-rear direction nesting (x ⁇ x ′), but the front leg x is larger than the rear leg.
  • (X> x ′) may be configured such that a plurality of chairs 101 are nested in the front-rear direction.
  • the above example shows an example in which the right leg interval y is smaller than the left leg interval y ′ (y ⁇ y ′).
  • a configuration may be adopted in which a plurality of chairs are nested in the left-right direction as being larger than the left leg y ′ (y> y ′).
  • the front-rear direction X and the left-right direction Y can be nested without distinction. Thereby, it is possible to further save the trouble of aligning the leg 120 in the nesting direction during nesting, and it is possible to provide the chair 101 that can be nested from a plurality of directions.
  • the leg arrangement of the leg portion 120 in the chair 101 of the present invention is asymmetrical, and in the front view of the chair 101, the pair of left and right legs is located inside the other pair of left and right legs, And in the side view of the chair 101, either the left or right pair of front and rear legs is positioned inside the other pair of front and rear legs, so that the legs can be configured to be nestable from a plurality of directions,
  • the shape and arrangement of the legs are not particularly limited.
