The mechanism comprises an extension member fitted to the frame of the dropend, a stay pivotally connected between the extension member and the frame of the chair and a cam track to guide the end of the extension member as the drop-end is raised and lowered. A particular feature of the invention is that as the drop-end is lowered it moves inwardly relative to the seat to prevent any gap between the seat and drop-end upholstery when in the dropped position. The drop-end is supported from below and, in a preferred arrangement, can be set in an intermediate position.
