Context: A standing wheelchair (also known as a standing chair, a wheeled stander or a stander) is assistive technology, similar to a standing frame, that allows a wheelchair user to raise the chair from a seated to a standing position. The standing wheelchair supports the person in a standing position and enables interaction with people and objects at eye level.

Types and function
Standing wheelchairs can be either manually operated, have power-operated wheels but manual lifting mechanisms or be fully powered with, for example, hydraulic lifting mechanisms. They are used both to achieve regular mobility and to stand the person up using hydraulics or other power sources. Some standing wheelchairs may be driven from the standing position, however there is some medical concern of an increased risk of long bone fractures while driving due to the legs being under a heavy load.
