In the past, there has been discussion of various kinds of helpful walkers. My elderly relative who just moved in with me has just a basic type with small wheels in front & no wheels in back. He does well with this in the house, but.................. I'm in a lovely rural setting where the ground is somewhat rough & am wondering if there's a better walker for this. I've heard on this list of U-walkers, ones with seats, ones which will catch you somehow if you stumble, etc., but didn't pay atttention when they were being discussed, as I didn't need one then. Unfortunately, in this rural area, neither the PT nor the HHC store is knowledgable about these. Can anyone suggest what might be best & where to get it? M.Dawn 56/6
