ABSTRACT:
An article of upholstered furniture, such as an easy chair or sofa, has a padded back rest comprising a first portion which has a rigid insert embedded therein, and a second portion which has a flexible linkage embedded therein hingedly connected to the rigid insert in the first portion. The second portion is adapted to be manipulated relative to the first portion from a first position wherein said second portion overlies the back rest, to a second position wherein the second portion is folded upon itself and extends vertically above the back rest. A linkage embedded within the second portion is arranged to assume a variety of curvatures as the second portion is manipulated relative to the first portion of the back rest, and is constructed to exhibit a limit position which prevents the padded second portion from being displaced rearwardly relative to the first back rest portion when the second back rest portion is in its second position.
