ABSTRACT:
An apparatus that is placed on a soft seat, such as an easy chair or sofa to help its user in being seated and in arising includes a rigid U-shaped lower frame that is spanned by a sheet of pliable material that is in contact with the seat, and further includes an upper U-shaped frame formed of tubing that is spanned by a rigid panel. The upper frame is resiliently and pivotably mounted to the lower frame by means of left and right torson springs, which apply an upward force to the rigid panel, partially offsetting the user's weight when the user is seated on the rigid panel. The apparatus is provided with left and right hand holds that permit the user to steady himself as he sits down or arises. The apparatus is stable in use and easily portable owing to its lightweight construction.
