Abstract
Abstract An article of furniture and method for assembling the same are disclosed for use wherein a membrane is supported between two opposing frame members. The membrane is attached to the side frame by a first set of fasteners. Thereafter an elongated strap and an elongated web are attached to the side frame overlying the edge of the membrane The first and second halves of a slide fastener are attached to the longitudinal edges of the web and are selectively interengaged to enclose the fasteners and conceal the same from view. Alternatively, an upholstery pad can be attached to the article of furniture such that it overlies the membrane. A second elongated web is attached to the underside of the pad such that the web is spaced inward from the outboard edge of the pad. The second half of the slide fastener is attached to this second elongated web and is selectively interengaged with the first half of the slide fastener which is fixedly attached to the side frame. The outboard edge of the upholstery pad extends outwardly such that it covers the fasteners and conceals them from view. In another embodiment, the membrane and a first half of the slide fastener are attached by fasteners to the opposing frame members. A fabric strip is attached to the membrane to conceal the fasteners. A second half of a slide fastener is fixedly attached to an upholstery pad. The first and second halves of the slide fastener engage to attach the upholstery pad to the chair and to conceal the fasteners from view. In yet another embodiment, the membrane is attached to the opposing frame members by fasteners. An elongated strip is mounted to the support member such that a portion selectively overlies the fasteners. The elongated strip is preferably mounted in a groove adjacent the edge of the membrane.
