Rollators are also known as four-wheel walkers. They are walkers that include seats, wheels and brakes and are ideal for people who require stability when they lift their feet to walk forward. The most obvious perk of a rollator is that it has wheels on the end of each leg. This means that you will be able to move the walker along more smoothly, rather than having to steady yourself enough to be able to lift the walker and set it ahead of you every few steps.
