One button collapses this aluminum walking frame flat, and a second set of buttons steps the legs through eight heights from 29 in to 36 in. The frame weighs 5.5 lbs yet carries 400 lbs, helped by thick-walled aluminum alloy tubing and a widened 20.5-in W by 18-in D stance. Two modes are built in: lock the sides for a rigid frame, or release them for reciprocal walking where each side advances in turn. PVC handgrips resist wear and stay comfortable for long holds. Rubber tips on all four legs grip smooth floors, and the walker arrives assembled with no tools and no hardware bag to lose. Folded flat it slips behind a car seat or into a closet, which suits travel, recovery at home and everyday indoor use.
