Abstract: A load-supporting structure for a chair includes a receiving surface component provided with a curved receiving surface configured to receive a load from a seated person; a load supporter supporting the receiving surface component from a back side of the receiving surface; and a curved shape-changing portion configured to change a curvature radius of the receiving surface from a curvature radius in an initial state thereof to a greater curvature radius than that in the initial state in accordance with a load received by the receiving surface component. The receiving surface component generates a biasing force for returning the curvature radius of the receiving surface to that in the initial state.

Abstract: A chair of an aspect of the present disclosure includes: a support base; and a chair body including a seat frame that extends in the forward-rearward direction and forms at least part of a seat, and a back frame that is provided in the rear end of the seat frame to be pivotable around an axis O1 extending in the left-right direction, extends upward from the seat frame, and forms at least part of a backrest. The support base includes a slider that supports, in front of the axis O1, the seat frame movably in the forward-rearward direction, and a backrest-supporting shaft that supports, below the axis O1, the back frame pivotably around an axis O2 extending in the left-right direction.

Abstract: A booth includes a booth main body including a facing panel, a right-side panel, and a left-side panel, a top plate, and an inclined panel that extends from a booth left front-end portion of the right-side panel of the booth main body while being inclined to become farther from the facing panel toward the right-side panel in the plan view and forms an entrance into the booth main body between the inclined panel and a booth right front-end portion of the right-side panel of the booth main body. The top plate includes a panel side edge portion that extends along at least the facing panel and the right-side panel, and a front edge portion that includes a first edge portion that becomes closer to the facing panel from a first end on the right-side panel side of the front edge portion toward the left-side panel.
