Abstract
A back rest construction which may be incorporated into an upholstered chair or recliner, or which may be used in a portable back rest either alone or in combination with a seat. The construction includes a frame with a vertical track carried on it and which in turn carries a lumbar support that may be moved up and down on the track. The lumbar support not only may be moved vertically to adjust its height, but in addition, it may be moved toward and away from the plane of the frame so as to decrease or increase the support provided by it.
