A portable seating assist device for use on a wide range of seating furniture comprises a base portion to be placed on the horizontal surface of a chair or the like and a seating surface which is hingedly mounted to the base. A compression spring is mounted between the seating surface and base to urge the two apart an allow upwardly assisted motion between a closed and open position. The seating surface is hinged in two sections so that the rear section forms a stable platform in the raised position. Levers at the front corners of the seating surface assist in initiating the lifting action.
