Nita > Yes Nita, I forgot the name, but it is a roller with four wheels maybe ten in. diameter, and holders like a bike, with a basket on the front chassis and a seat between the hand grips. If she gets tired, she puts the brakes on, turns gently around and sits. After removing the basket, you can pull a tab and then the roller can be folded in half so that it can be transported in a car. I usually take it when going to department stores. Medicare paid 80% of the cost up to $240, I believe, and our saleswoman came to the house and provided the necessary papers for Medicare. Actually, I think this note should go to the list. Nita, you keep well, you are needed. Fondly, Michel
