Forward and rearward facing wheeled legs are provided attached to the jack base. Each forward facing leg is hinged to the jack base though a universal joint thereby allowing the legs to be folded into a compact position for transportation or storage. A segmented lever is provided. A folding seat is provided having a back hinged to a bottom. Strap means are attached to the seat bottom and to the seat back for securing to the seat both the upper and lower torso of a fallen invalid who is positioned prone on a floor surface. The seat includes dual function means attached to the back, both for using the segmented lever to provide leverage to the seat, whereby the prone invalid is rotated to an upright sitting position, and for engaging the jack hook, whereby the seat containing the prone invalid is raised above the floor with the invalid in an upright sitting position.
