I broke my femur and needed to use a walker until I could put full weight on that leg. I came home with a striped down walker and when I wanted to take food and other stuff across a room to where I was sitting realized that it wasn't possible. The I started searching for a tray or pocket that would hold things. They tray is the perfect thing and I can take food or drink from the kitchen into the family room without spilling it everywhere. And the tray makes the walker much more staple!
