The company's curved stairlifts are purpose-built to navigate complex split-level geometries (turns, multiple landings, varied heights) without mid-journey transfers—a significant advantage over dual-lift competitors. The Starla and Siena product lines offer flexible positioning and extensive customization. However, Stannah's premium pricing ($10,800+ curved start), opaque quoting process (requires free survey, no online calculator), long custom fabrication lead time (estimated 6–8 weeks, not published), and weak residual value on custom curves make it less suitable for cost-sensitive, time-constrained, or temporary-use scenarios. For split-level homeowners with moderate-to-strong budgets, complex staircase geometry, and desire for professional, reliable, long-term mobility, Stannah ranks as a strong choice. For budget-first or simple two-flight split-level homes, competitors offering straightforward straight-lift dual strategies or lower-cost curved alternatives may provide better value.","fit_assessment":{"best_considered_for":["Homes with 2-3 connected flight sections (landing-connected), where users prefer continuous journey without mid-flight transfers","Complex staircase geometries (L-shaped, U-shaped, spiral turns, or irregular angles) where only custom curved rails fit","Users prioritizing comfort, safety features, and aesthetic blend into home over cost minimization","Residences where landing clearance and space preservation are critical (Stannah curved rails hug tight turns)"],"direct_answer":"Stannah is a strong fit for split-level homes with multiple flights or landings.
