Designed around everyday life
Comfort, control, and a little more independence.
Whether you are planning ahead or helping a family member, Otolift brings useful features together in a chair that feels at home.
A slim modular rail
Precisely engineered rail sections form a route around your staircase. The single rail measures just 2⅜ inches in diameter, creating a compact appearance through turns and landings.
Powered footrest, standard
Fold the footrest without bending down. The seat, armrests, and footrest fold up when the lift is parked to leave more room for others using the stairs.
Controls within reach
An ergonomic joystick operates the lift. The armrest dashboard shows lift status and battery level, and wireless call/send controls bring the chair to your floor.

How to use the Otolift Modul-Air Smart
Watch Harmar’s demonstration of the chair, controls, and everyday operation.
Product demonstration from Harmar. Your installer will explain the operation of your configured lift.
Your stairs. Your layout.
A curved stairlift fitted to your home.
Turns, intermediate landings, and spiral layouts need a rail planned for their route. Otolift’s modular system can follow the inside or outside bend of the stairs, with start and finish options to suit the available space.
The rail supports attach directly to the steps. Ohana will assess stair width, headroom, doorways, landing space, and the rider’s needs before recommending a configuration.
Optional powered swivel
The powered swivel upgrade turns the chair using the joystick. It also enables reverse-drive configurations that can help negotiate tighter stairways, where the survey confirms a suitable fit.
Fit and options depend on your staircase and individual needs.
Thoughtful features
Built for an easy everyday routine.
- A comfortable seat: supportive seating with synthetic-leather upholstery.
- A simple seat belt: designed to fasten with one hand.
- Obstacle detection: the lift stops when it detects an obstruction.
- Battery-powered travel: operation can continue during a power outage while sufficient battery charge remains.
- Quiet movement: designed for smooth, quiet travel between floors.

Common Otolift questions
Is Otolift suitable for stairs with turns or landings?
The Modul-Air Smart is designed for curved staircases. Its modular rail can follow turns and landings, including some spiral layouts. A staircase survey determines the fit and configuration for your home.
Can it fit a narrow staircase?
The slim rail and folding chair help conserve space. The optional powered swivel and reverse-drive configuration may help with tighter layouts. Ohana must check the stair width, headroom, and rider’s needs before confirming suitability.
Does the footrest fold automatically?
A powered folding footrest is standard, so you do not need to bend down to raise or lower it.
Will the stairlift work during a power outage?
The lift runs on batteries and can continue operating while sufficient charge remains. The number of trips depends on battery condition, charge, rider weight, and the staircase. Charging requires power.
How much does an Otolift stairlift cost in Hawaii?
Your price depends on the staircase route, rail configuration, selected options, and installation and delivery arrangements. Contact Ohana for a quote for your home.
How soon can it be installed?
The modular rail system can reduce manufacturing lead time compared with a fully fabricated curved rail. Your Hawaii installation schedule depends on the survey, equipment availability, delivery, and installation arrangements. We will discuss timing with your quote.
Can this model be installed outdoors?
This page covers the indoor Modul-Air Smart. For outdoor curved stairs, explore the Helix curved stairlift and ask Ohana about an outdoor configuration suited to your location and weather exposure. For straight exterior steps, see our outdoor stairlifts.
