When evaluating a Steel Walker Factory, prioritize the frame material grade, typically high-tensile carbon steel or stainless steel, to ensure a balance between weight and structural integrity. The weight capacity should be a minimum of 300 lbs (136 kg) for standard models and up to 500 lbs for bariatric versions. Key features must include adjustable height mechanisms with secure locking pins, non-slip rubber tips for stability, and ergonomic handgrips made of high-density foam or PVC to prevent user fatigue.
