Wheelchair and power wheelchair

What are wheelchairs?

Wheelchairs are specially designed chairs with fitted wheels where the user can manually propel the seats by turning the wheels with hands or where the user can electrically propel the seats by turning the wheels with the help of a motor or a joystick. The wheelchairs are designed with handles at the back for helpers to push the wheelchair.

People who are physically impaired, or who suffer from various illnesses and do not have the ability to walk and sit use a wheelchair.

Wheelchair is a very old technology. Harry Jennings and Herbert Everest, the two friends and mechanical engineers invented the first lightweight, collapsible, steel wheelchair in 1933. And since then, they have become the mass manufacturers of wheelchairs.

The wheelchair is propelled with the help of an electrical motor. This kind of wheelchair is used mainly by those people who travel long distance and for whom manually operating a wheelchair could be fatiguing. Electric wheelchairs are combined with style, functionality, comfort, durability, and convenience.
