Walkers and Rollators are used for someone to get around more efficiently, when a little assistance is provided and a wheelchair is not needed. They can also be used with a wheelchair or mobility scooter but for shorter distances.

 

The difference between a rollator and walker is a walker does not have wheels and a rollator does. The  wheels will help guide someone more smoothly while leaning forward more where a walker is used when some one is able to pick it up as one walks. Both are very popular and the most popuara manufacturer of these products is Invacare.
