An oval-shaped T-nut that is received within an oval receiver machined into the upholstered panel to be secured to a chair frame is provided. The oval shape of the T-nut prevents the oval-shaped T-nut from rotating when a screw is driven into the T-nut. Further, this eliminates the necessity of stapling the traditional plastic T-nut to the chair panel, thus saving time and money associated with the manufacture of an upholstered metal frame chair. In addition to the oval-shaped T-nut described herein, a novel U-shaped screw catch is also provided which cooperates with a barbed nylon or plastic push rivet to secure the upholstered chair panels to one another. Further, a method for connecting upholstered seat back panels to the tabs positioned on the back frame of a chair, utilizing the T-nut and the screw catch is disclosed.
