Abstract
A method of manufacturing a seating unit, such as a chair, includes manufacturing a cushion made from a non-woven fibrous material, and attaching the cushion to the seating unit for comfortable support. The cushion is made by cutting a blank from non-woven fibrous sheet material, steam-forming the blank into a pre-formed cushion shaped to support a user, and attaching a stiffener panel to the pre-formed cushion to provide a stiffened cushion assembly. The cushion assembly is aesthetically covered and assembled to seating unit. Advantageously, trimmings from the fibrous material can be recycled.
