Four of seven platforms named it during ranking discovery, and six of seven fit assessments landed on mixed, good, or strong rather than a clear rejection. Its strongest case is a single short, straight flight that ends at a door or tight top landing, where the Zero Intrusion configuration removes the usual rail overrun. The main limitation is structural: it is a straight-rail product and cannot serve multiple half-flights, turns, or intermediate landings as one…","target_buyer":"Homeowners with split-level layouts, short stair runs, or multiple half-flights that need flexible stairlift placement","topic":{"base_category":"Stairlifts","category_criteria":["Short-run compatibility","landing clearance","rail customization","parking options","installation complexity","transfer safety","quote transparency","total installed cost"],"geography":"United States","slug":"best-stairlifts-for-split-level-homes","title":"Best Stairlifts for Split-Level Homes","use_case":"Split-Level & Short-Run Staircases"}}
