Specification :

The rollator has been in use in Scandinavian and European countries for many years, but has only recently become popular in the United States. A rollator could best be described as a standard walker taken to the extreme. Four large tires replace the two small wheels and two posts of a walker. The handles of a rollator feature caliper brakes, much like a ten-speed bicycle. The user can squeeze these hand brakes to lock the wheels in place, or release them to continue walking.
