Walkers allow people who have lost the mobility of their legs due to old age or because of an accident and allow them to become mobile once again. Walkers can have four legs, two wheels on the front legs, or wheels on all four legs.
A 4 wheel walker can be used without lifting the walker off the ground as most walkers will require you to do. This lifting can be difficult and tiresome for some people, and they will benefit the most from walkers with four wheels.
These walkers will slide forward with pressure and this can be a major safety hazard. Use has to be made of the handbrakes that they are equipped with so that the walker does not slide forward when it is leaned on. They are easy to use on surfaces that are slightly uneven and can be navigated easily once the user has got used to maneuvering them.
