Dave, the walker has four wheels and a seat that comes down so I can sit. Don't really know what it is called. It folds up when using it with neighbor who took me for license plate, I broke the seat with my knee. He fixed it, but it doesn't fold up the same way any more, but is very sturdy. Cost about $148 originally, I think. My regular walker is easier to handle, but I can't sit down which I have to do.
