This is the Benz of rollators. Retails for $1600.  I got it because I wanted to take my mom outdoors on trails and to the beach and the lake and the barn. You can’t do that with an unsteady person or a traditional wheelchair. This thing has been amazing and I hate to give it up in case anybody else should ever need it but here we go. At 27” wide it rolls easily through doors. It switches from walker to wheelchair in about 30 seconds. The seat is super comfy with the backrest. The air tires make curbs and roots and rocks a breeze. Lots of storage and the color is cool too.
