Cushion-like devices designed to facilitate raise from a standard chair or sofa. These lifters typically consist of a portable, two-part hinged structure with a mechanism that lifts the seating surface, raising the person close to an upright position. Self-powered (e.g., using springs) and electrically powered lifters are available. Seat lifters are used to assist people who have lost sufficient upper and/or lower body strength to get up unassisted.
