Your questions, answered.

Turns and intermediate landings change the route a lift needs to follow. Helix uses a rail fabricated for the measured staircase. An assessment determines whether that approach suits your home; custom-made does not mean every staircase is suitable.

Discuss where the chair starts, stops and parks before approving the rail layout. Ask to see how those positions affect doors, walkways, charging and transfers. The parking example in the gallery is a manufacturer example, not a promise of the same arrangement in your home.

Try the seat depth, support, control reach and swivel together. Include getting on and off at each landing. The capacity rating alone cannot establish individual fit or the assistance someone may need.

The listed folded width is a product measurement, not a guarantee of usable passage around curves. Have the installer review clearance along the entire route with the chair occupied and folded, including any narrow turn or doorway.

Ask for a written schedule covering the survey, design approval, fabrication, site preparation and installation. Time on site is not the same as total lead time. This page does not promise same-day or next-day installation.

Ask which controls, charging positions, finishes and other options are included in your proposal. An outdoor package is a separate configuration to confirm, not an automatic feature of every Helix. Request the applicable manual, care plan, warranty responsibilities and service contact.

Before the rail is made

See the layout. Understand the choices.

Bring your everyday routine.

Which floors do you use most? Where do you need room to transfer? Do doors open near either landing? Those questions help shape the assessment.

Ask for the proposed route.

Review the rail path, parking positions, charging points and space alongside the chair. Have the installer explain anything you cannot picture before committing.

Keep exploring

Bring clear questions to your assessment.
