Bi-level handrails are the defining feature: a lower R-shaped rail gives something to push against while rising from a sofa, and the upper rail takes over once standing. Four grooved grips add friction across both levels. The gray aluminum frame spans 25.6-in W by 20-in D, adjusts through seven heights from 30 in to 37 in, and carries 440 lbs on a widened base with two non-slip foot pads. Two one-way pulleys let the frame glide forward without lifting, and a single button switches between fixed and reciprocal walking modes. Folded it flattens to 4.7 in thick and weighs 6 lbs. Thick-wall aluminum tubing resists deformation, and the frame wipes down with a damp cloth after outdoor use.
