A wheelchair is a mobilized form of chair using 2 or more wheels, a footrest, and an armrest usually cushioned. It is used when walking is difficult or impossible to do due to illnesses, injury, disabilities, or age-related health conditions. Wheelchairs provide mobility, postural support, and freedom to those who cannot walk or have difficulty walking, enabling them to move around, participate in everyday activities, and live life on their own terms.

Wheelchairs come in a wide variety of formats to meet the specific needs of their users. They may include specialized seating adaptions, and individualized controls, and may be specific to particular activities, as with sports wheelchairs and beach wheelchairs. The most widely recognized distinction is between motorized wheelchairs, where propulsion is provided by batteries and electric motors, and manual wheelchairs, where the propulsive force is provided either by the wheelchair user or occupant pushing the wheelchair by hand (self-propelled), by an attendant pushing from the rear using the handle(s), or by an attendant pushing from the side use a handle attachment.
