Three of the seven platforms in this study named it during ranking discovery, at an average listed rank of 4.0 and a best rank of 2. Its strongest case is the published 14.5-inch folded depth on the straight model, combined with a powered footrest and an optional automatically retracting rail for stairs with a door or walkway at the bottom . The main limitation is that the 14.5-inch figure is not a universal installed footprint: rail-start position, armrest behavior, and obstruction-sensor sensitivity are not…","target_buyer":"Families where other household members need to continue using the stairs safely after the stairlift is folded away","topic":{"base_category":"Stairlifts","category_criteria":["Folded depth","folding rail availability","automatic footrest","armrest folding ease","obstruction sensor sensitivity","parked footprint","installation fit","warranty coverage"],"geography":"United States","slug":"best-folding-stairlifts-for-shared-stairways","title":"Best Folding Stairlifts for Shared Stairways","use_case":"Shared Household Clearance"}}
