Abstract
An office chair is provided having a contoured back assembly comprising a back frame and a suspension fabric. The fabric is attached to the back frame through a spline wherein the back frame has a three-dimensional contoured shape formed by overlapped frame rings with the fabric being joined thereto by a spline. The fabric is secured to the frame by a machine wherein the fabric is first stretched from the outer edge of the fabric and then is clamped to a frame surface in the pre-tensioned or pre-streched condition. The fabric edges are allowed to hang loose and then fixed in the frame by a spline. Once secured, the fabric is unclamped from the frame.
