Although I felt more than a little ridiculous trying it out, I recently borrowed my mom's extra walker to help me on a planned trip. I went to Washington DC with my 2 teenaged sons. I knew there would be A LOT of walking and standing around. I just can't do that for long periods. Mom'a walker was a godsend.....it literally saved our trip. I wanted to have a seat available where ever and whenever I needed one. Being able to leave my pocketbook, the camera bag, and our snacks and coats on the rollator was an unexpected bonus and really saved my neck.

The 4 wheeled versions are called rollators. Mom and I are BIG girls, so we got a bariatric rollator like this one http://www.overstock.com/Health-Beau...130203051332:s

Medicare covers the cost of a walker if you have a doctor's order.
