Abstract: A folding chair includes an articulated armrest to initiate a folding of the chair. The armrest can have a spring-loaded, releasable coupling, where the chair will not fold inadvertently, while lifting the chair by the armrests, without release of the coupling. The folding armrests can be linked to movement of the seat structure during chair folding. The chair can include four leg posts, two articulated armrests, where each armrest is rigid and has a front and rear arm section, and two seat links, where each seat link is pivotally attached to one of the front or the rear arm section, and to a side support of a seat bottom, where the chair is configured, when the armrests are articulated, to fold the chair. A releasable coupling can be included, between the front and the rear arm sections, where, when the coupling is released, the chair is folded.
