Straight Stairlifts for Home

Harmar Pinnacle Premium straight stairlift

Compare straight stairlifts for everyday access at home

Explore Harmar Summit and Pinnacle seated stairlifts for straight indoor staircases. Compare rider capacity, chair dimensions, controls, rail options and power arrangements. The Pinnacle models listed here use battery power for operation during an outage when adequately charged; the Summit SL350AC uses household AC power.

Measure the staircase, landings, doorways and transfer areas, and arrange a site assessment to confirm rail length, installation and clearance. Check seat fit and the rider's ability to transfer and operate the controls. Folding features and powered options vary by configuration. Follow the installer's and manufacturer's instructions for use, battery care and scheduled maintenance.
