Curved vs Straight Stairlifts for Seniors
If your aging parent is having trouble with stairs, a stairlift can help them stay safe, and stay in their home longer.
But not all stairlifts are the same.
The two main types, straight and curved, serve different needs depending on your home’s layout. This guide will walk you through the key differences, costs, pros, and how to make the right decision.
What Is a Stairlift?
A stairlift is a motorized chair that travels up and down a rail mounted to the stairs. It gives older adults a safe, easy way to get between floors without the risk of falling.
Stairlifts include:
- A seat with safety features (belt, armrests)
- A track that follows the staircase
- A motor and control system
- Battery backup in case of power outage
They’re especially helpful for people with balance issues, arthritis, or limited mobility.
“Falls are the leading cause of injury for older adults. A stairlift can prevent a fall and allow someone to stay in their home longer.”. Dr. Warren Wong
