Abstract: A chair is disclosed in which a support member is provided by a membrane shell having at least one structural support region of relatively low resilience and at least one flexing region of relatively greater resilience to provide for the structural integrity of the membrane shell yet to permit the support surface to deform under loading for the comfort of the person seated thereon. Further, a folding chair is disclosed which provides a plurality of legs hingedly connected to the support member and disposed to swing between a first position which folds flatly against the underside of the support member and a second position which distends the legs for holding the chair in a convenient position for use.
