Make an informed next step
A straight flight.
A considered next step.
Explore a seated lift for a straight staircase, with attention to the route and the person who will use it.
Understand the options
Start with the whole staircase.
A straight stairlift follows one continuous flight without bends or an intermediate landing. It can make upstairs rooms easier to reach while you remain seated, but the rail is only one part of the fit.
HomePro can help you compare the space at each landing, getting on and off, seat and control options, and the room left for others using the stairs. If your route turns or crosses a landing, explore a curved layout instead.

Clarity before commitment
Three parts of the conversation.
The route
Start at the bottom step and follow the full route upstairs. Include nearby doors, handrails, the landing space and where the chair will park when it is not in use.
The person
Discuss sitting down, standing up and using the controls comfortably. Ask how the proposed seat, swivel and footrest fit the person who will use the lift.
The complete installation
Review the rail and mounting, available power, installation scope and operating instruction. Ask who handles service after installation and what the written warranty includes.
Useful answers
Questions worth asking.
Explore the curved-stairlift route rather than assuming a straight rail can accommodate it. The layout needs assessment.
Compare the actual model, fit, features and ownership terms after the staircase and intended use have been reviewed.
Confirm the selected model’s documented power and backup operation. The entire category should not be treated as battery-backed.
