A wheelchair is a device used to assist individuals who have difficulty walking or moving independently due to a disability or injury. It typically consists of a seat, backrest, and two large wheels, as well as two smaller wheels in front to aid in steering and maneuvering. Wheelchairs can be manually propelled by the user or pushed by another person, or they can be powered by batteries and operated by the user through a joystick or other control system. There are also specialized wheelchairs designed for specific purposes, such as sports or rough terrain. Wheelchairs provide individuals with greater mobility and independence, enabling them to participate more fully in everyday activities and improve their overall quality of life. #hospital bed on rent #
