Walker rollator, also known as a rolling walker, wheeled walker, or medical rolling walker, is a mobility aid that features wheels on all legs. The wheels allow the user to easily push the rollator forward, eliminating the need to lift the device when moving. However, it's important to note that rollators should not be used to support body weight as this can result in falls. Many rollators come with a seat, some also have a removable backrest, to provide balance while sitting.
