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.

7. A back construction comprising:
-
a back support including a lumbar region adapted to support a seated user;
a cover supported by the back support, the cover having opposing side edges extending vertically along a front surface of the back support but not attached to the back support along a majority of the lumbar region; and
an edge stabilizer attached to the side edges and abuttingly supported on the back support to control a position of the side edges relative to the back support in the lumbar region but allowing the opposing side edges to move in at least one direction on the back support, whereby forces on the cover result in controlled movement rather than uncontrolled shifting of the cover assembly. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A back construction comprising:
-
a back support configured to support a seated user and including vertically-extending edge sections and a flexible region between the edge sections where the seated user is more flexibly supported than at the edge sections; and
a cover assembly supported by a front surface of the back support, the cover assembly including opposing side edges unattached to but supported by the edge sections of the back support, the cover subassembly also including an edge stabilizer extending along and attached to the opposing side edges along at least a majority of the edge sections, the edge stabilizer being sufficiently structural to control a position of the side edges relative to the edge sections. - View Dependent Claims (16, 17, 18, 19, 20, 21)
