The Metro Walker is the most compact, portable, easiest open-and-close walker ever invented. When folded, the Metro Walker is about a quarter the size of the average walker. It fits in small spaces, like an airplane overhead bins or a tiny car trunk. The unique design allows it to open and fold up effortlessly. To fold, just raise the easy-release lever with one hand and the walker collapses. To open, slide the handles apart. It’s that simple!!! The Metro Walker is lightweight, but sturdy and strong, supporting up to 250 lbs. Mfg's Model No. 4100 Stander
