Five of the seven platforms in this study named it during ranking discovery, and it finished with an average listed rank of 3.4 and a best rank of 3. Its strongest case rests on published compactness: a folded width to the footplate of about 12.6 inches and minimum rail intrusion of about 6.3 inches . The main limitation is that no source establishes a single verified minimum staircase width, and the roughly 25.4-inch swivel radius can become the binding constraint on a tight landing (,…","target_buyer":"Homeowners needing a stairlift installed on narrow stairways (under 30 inches) without blocking foot traffic","topic":{"base_category":"Stairlifts","category_criteria":["Minimum staircase width requirement","folded profile depth","slim rail design","folding footrest and armrest clearance","swivel radius"],"geography":"United States","slug":"best-stairlifts-for-narrow-staircases","title":"Best Stairlifts for Narrow Staircases","use_case":"Compact & Narrow Stairways"}}
