An electrically-powered cushioned device designed to be placed on a chair or other surface for sitting, and to help lift its occupant to stand from the sitting position; it is typically used by elderly or disabled patients who have difficulty rising from a seated position. It may be in the form of a portable, two-piece, hinged structure with a mechanism that lifts the seating surface mechanically (e.g., by springs), or in the form of an inflatable cushion with an integrated pump. It is normally available [non-prescription] over-the-counter (OTC) for use in the home and healthcare facility.
