Should I purchase a walker or rollator?

Answer:

Walkers - Walkers are built with telescoping aluminum supports, the standard walker is a great way for individuals with injuries or disabilities to get around. Better support than a rollator.

Rollators (walkers with wheels) - A rollator is basically a standard walker with tires attached. Unlike a regular walker, a rollator doesn't involve the lift that a normal walker requires. Makes walking a smoother process. A rollator however requires that the user be stable enough to not let it get away from them since it has wheels.

Its best to always ask a medical professional before purchasing any type of walking or mobility aid.
