How do you make stairs safe for elderly people?

To make stairs safe for elderly people, ensure they are well-lit and free from clutter to prevent tripping hazards. Install handrails on both sides of the stairs for better support, and use non-slip materials on the treads to enhance grip. Clearly mark the edges of each step with contrasting colors to improve visibility. Lastly, consider adding stairlifts or ramps for those with mobility issues.
