Wheelchairs are mobility devices that are used by persons with limited physical mobility due to illness, injury, or disability. Wheelchairs can be manual (powered by the user) or powered (powered by an electric motor). Manual wheelchairs provide a low-cost, lightweight, and often more mobile option for users, while powered wheelchairs offer more range and power. Wheelchairs are designed to meet the needs of the individual user, including features such as adjustable heights, reclining backrests, and specialized seating systems
