Used Pinnacle stair lifts by Harmar are reasonably priced, reliable, energy-efficient, and low-maintenance. Fold up the seat and footrest to compact the unit to a miniscule width of 11 inches - no need to worry about tripping over it as you walk by! The DC battery motor carries a charge constantly, so that if your home's power goes out, you'll never be stuck on the lift. Used Pinnacle stair lifts must be installed by our technicians. 90-day parts-only warranty included with purchase.
