Wheelchairs need to be compact and light so that that they can be transported wherever necessary for its user. Chairs can be self-propelled or powered and can be of the folding variety.
Aluminium wheel chairs are favoured by many users because of their lightweight. Manufacturers cut down weight by having tubing of oval shapes, and reduce the weight further by welding the joints instead of using bolts and brackets. Carbon fibre frames are still lighter, but their high cost acts as a deterrent.
These lightweight wheel chairs made of aluminium are ideal for use in hospitals and other care facilities, as they are easy to push and navigate when you have to go round corners or negotiate slopes. They are also easy to place in vehicles, and if they are of the folding variety they are easy to stow away when not in use.
